To turn this indication off, press any key. - Indicates that the monitor mode is enabled. This mode disables Call Guard squelch and other squelch control features so that all messages are heard on conventional systems (see page 50).
GENERAL OPERATION • If a conventional system is selected, take the microphone off-hook and if someone is using the channel, voice is heard. If no one is using the channel, the squelch control can be adjusted counterclockwise as described in “Setting Squelch Control” on page 18 and noise is heard. It is not possible to unsquelch the transceiver in this manner when a Multi-Net or LTR system is selected.
GENERAL OPERATION bottom line. For example, a “SECURITY” system and “CAR 220” group are displayed as follows. The system and group numbers are not displayed in this mode. System Alpha Tag Group Alpha Tag Alpha Tag Display Mode Selecting the System and Group The front panel Select switch is used to change the system and group. Pressing this switch toggles between the system and group select modes, and then rotating it increases or decreases the system or group.
GENERAL OPERATION System Select Mode Group Select Mode Select Mode Indication With Alpha Tag Display The transceiver can be programmed so that after a change is made, the current select mode remains enabled or a default mode is selected after a delay of up to 15 seconds. This programming also controls the mode that is selected when power is turned on. Setting Squelch Control NOTE: This sets the squelch level used for conventional calls.
STANDARD CALLS 4. If both narrow and wide band channels are used, perform this adjustment on both types because separate settings are maintained. NOTE: Some readjustment may be required if weak messages are not heard or unsquelching occurs when no messages are present. STANDARD CALLS Introduction Most calls you make are probably the standard type described in this section. These calls are between you and another mobile or control station.
STANDARD CALLS successfully accessed. If it is not enabled, no tone sounds when the system is successfully accessed. The proceed and other tones can be disabled as described in “Tone Select” on page 32. • If the radio system is busy, the busy tone sounds (see page 54) and “BUSY” is indicated on the lower line of the display. If you continue pressing the PTT switch, the system is accessed when it becomes available.
TELEPHONE CALLS AND OTHER SPECIAL CALLS 2. Select or scan the system and group programmed for the call you want to receive (see page 35 for scan information). 3. When the message is received, the display usually changes to the system and group of the call. Take the microphone off-hook and press the PTT switch to talk and release it to listen. If scanning, a response may not automatically occur on the group of the call (see page 39).
TELEPHONE CALLS AND OTHER SPECIAL CALLS Busy and Out-Of-Range Conditions Busy and out-of-range conditions are indicated the same as with Multi-Net and LTR standard calls described on page 19. The following additional features may be available with telephone calls: Busy - With LTR operation, if Busy Queuing is programmed (see page 48), the call is automatically placed in a queue when the PTT switch is released. The Busy Queuing mode is indicated by “IN QUEUE” in the display.
TELEPHONE CALLS AND OTHER SPECIAL CALLS Receiving a Telephone Call 1. Turn transceiver power on and set the volume as described starting on page 15. 2. Select or scan the system and group programmed for telephone calls. When a telephone or Multi-Net special call group is selected, is displayed. 3. When “ringing” is heard, press the PTT switch and respond. The PTT switch must be pressed to talk and released to listen the same as with standard calls. 4.
TELEPHONE CALLS AND OTHER SPECIAL CALLS 3. Dial the 4-8 digit number using the microphone keypad. Refer to step 4 on page 22 for more information. 4. A tone then sounds to indicate that the call was accepted by the system. If this tone does not sound, an incorrect or unauthorized number may have been dialed. The call then proceeds as follows: Unique ID Call - Ringing is heard to indicate that the other transceiver is being rung.
GENERAL FEATURES Landside-Originate Calls Calls can be placed from a landside telephone to your transceiver if the radio system and transceiver have that capability. With most systems, a mobile can be called directly (each has a unique telephone number). With others, a mobile may be called as follows: 1. Dial the number of the radio system in which the mobile is operating. 2. When the system answers, a short tone sounds to indicate that the number of the mobile should be dialed.
GENERAL FEATURES Call Indicator The call indicator is “C” in the upper part of the display as shown in the following illustration. The purpose of this indication is to show that a call was received while you were away from the vehicle. Individual groups can be programmed for this feature and it then turns on when a call is received on one of those groups. Call Indicator This indicator is turned off by pressing any button or turning transceiver power off and then on.
GENERAL FEATURES Automatic Operation - The transmitter automatically transmits an emergency message on the emergency system/group. The message is transmitted without pressing the PTT switch and at the highest priority. Emergency transmissions continue until an acknowledgment is received from the dispatcher. Encryption Voice encryption is an optional feature that prevents conversations from being monitored by casual eavesdropping and analog scanners.
GENERAL FEATURES Function (FCN) Switch If an option switch is programmed for FCN (function), it performs the following functions. If this switch is not programmed, these functions are not available. When the function select mode is active, “FCN” is displayed on the lower line of the display. The function mode is automatically exited after 8 seconds of no activity. Menu Mode Select - Pressing FCN twice selects the menu mode as described on page 33.
GENERAL FEATURES When enabled, the horn alert pulses on and off for 1-8 cycles and then goes back to the disabled state. To change the currently selected horn alert mode, the HORN option switch or HRN ALRT menu parameter can be used if available (see page 32). The horn alert is programmed to operate in the manual or automatic mode (see descriptions which follow). If the ignition switch does not control transceiver power, only the front panel power switch affects operation when applicable.
GENERAL FEATURES Power Turn-Off Delay Your transceiver may have been installed so that the vehicle ignition switch as well as the front-panel power switch control transceiver power. If this is the case, both the ignition switch and the front panel power switch must be on for transceiver power to turn on. When the ignition switch controls power, turn-off delays of Immediate, 10, 20, 30, 40, or 50 minutes, 1, 2, 4, 8, 10, 12, or 16 hours or Forever can be programmed.
GENERAL FEATURES On conventional systems, the Transmit Disable On Busy feature can be used to automatically perform monitoring (see page 51). The proceed tone then does not sound if the channel is busy. Otherwise, the proceed tone (if enabled) sounds on conventional systems even if the channel is busy. With all operating modes, if encryption is used, a 0.9-second delay occurs before this tone sounds and two beeps are heard instead of one. A short delay may also occur with conventional calls.
OPTION SWITCHES AND MENU MODE One use of the time-out timer feature is to prevent a repeater from being kept busy for an extended period by an accidentally keyed transmitter. It can also prevent possible damage to the transmitter caused by transmitting for an excessively long period. Tone Select If the TONES menu parameter is selectable, the tones that sound can be selected. Otherwise, the tones that sound are fixed by programming. The following choices are available.
OPTION SWITCHES AND MENU MODE column. Refer to the page listed in this table for a description of the function. If a function is controlled by an option switch, it cannot be controlled by the menu mode and vice versa. Some switches may not be used and are then disabled. Menu Mode Introduction The menu mode is selected by pressing the FCN switch twice. If this switch is not programmed, the menu mode is not available.

SYSTEM AND GROUP SCAN 5. The selected status conditions for the various functions are saved when the menu mode is exited in one of the following ways: • • • Pressing the FCN switch again Pressing the PTT switch Automatically when time-out occurs 2 seconds after a change is made or 8 seconds after no changes are made. NOTE: Calls cannot be received or transmitted while the menu mode is selected.
SYSTEM AND GROUP SCAN System Scan List System or Group Scanning Selected Group Scan List System or Group Scanning Occurring The type of scanning selected is determined by the menu mode SCN TYPE parameter (see page 33). If that parameter is not selectable, the type of scanning is fixed by programming. The available scan types are as follows. Single and multiple site scan may also be selectable (see page 37).
SYSTEM AND GROUP SCAN Single and Multiple Site Scan Single and Multiple site scanning (see descriptions which follow) are selectable if the SCAN SEL menu parameter if it is available. If this parameter is not available, scanning is fixed in one of these states by programming. If you can select this parameter, your system operator may provide more information on which type to use.
SYSTEM AND GROUP SCAN inal group scan list is again active. Systems and groups can be deleted from the scan list while listening to a message on the system or group by pressing the A/D switch in the normal manner. Scanning resumes shortly after the system or group is deleted. Scan list programming is not available if the A/D switch is disabled. In addition, the group scan list is not programmable if the group scanning is disabled on the current system.
SYSTEM AND GROUP SCAN There is also a scan continue timer that may be programmed. This timer controls the maximum time that a call is received before scanning resumes. Times up to 60 seconds can be programmed. This prevents scanning from being delayed for long periods by lengthy calls. If the menu SCN CONT parameter is selectable (see page 33), this feature can be turned on and off.
MULTI-NET, LTR, AND CONVENTIONAL MODES disabled), the selected system/group is again displayed. Therefore, you can respond to a call without changing the selected system/group as long as you do so before scanning resumes. Fixed System/Group Transmit in Scan Each bank can be programmed so that transmissions in the scan mode that are made while scanning is occurring are on a preprogrammed system/group. Note that scanning must be occurring (scrolling underline displayed) when the transmitter is keyed.
MULTI-NET, LTR, AND CONVENTIONAL MODES include telephone, unique ID, and directed group. Multi-Net features are described starting on page 43. LTR operation is similar to Multi-Net operation. The main difference is that the preceding features are not available. The two types of calls that can be placed with LTR operation are Standard and Telephone. LTR features are described starting on page 48.
MULTI-NET, LTR, AND CONVENTIONAL MODES Monitoring Conventional Channels Before Transmitting Regulations require that the channel be monitored before transmitting to make sure that it is not being used by someone else. If you were to transmit when someone else is talking, you would probably disrupt their conversation. As previously stated, monitoring is performed automatically in the Multi-Net and LTR modes. In the conventional mode, it must be performed automatically or manually as follows.
MULTI-NET FEATURES Monitor Mode Selected MULTI-NET FEATURES Standard and Special Calls Standard calls are between two mobiles or between a mobile and a control station, and special calls include telephone, unique ID, and directed group. Standard calls are described starting on page 19, telephone calls starting on page 21, and unique ID and directed group calls starting on page 23.
MULTI-NET FEATURES with all calls except telephone, and the dial tone sounds with telephone calls. The call can then be placed in the normal manner. When in the queue mode, calls are received normally. A response can be made to a call and Busy Queuing resumes shortly after the call is finished (if it was not on the selected group). If group scanning is enabled, it continues. However, system scanning is temporarily disabled, so calls are not received on other systems.
MULTI-NET FEATURES other selectable systems. While searching is occurring, “ROAMING” is indicated on the lower line of the display as shown below. When a new site is located, this message is no longer displayed, and the system and group of the new site is displayed. The new system is the first higher system with a different site that could be accessed (wrap-around occurs after the highest system is accessed).
MULTI-NET FEATURES message and exit this mode, press the FCN option switch again. This also occurs automatically 2 seconds after a change is made or 8 seconds after no changes are made. Up to eight status conditions such as “AT SITE”, “LEAVING”, and “LOADING” may be preprogrammed by your system operator. The selected status condition along with the unique ID of your transceiver is then displayed on the dispatcher’s console whenever the transmitter is keyed.
MULTI-NET FEATURES If a call is received on one of the fixed priority ID codes, either “PRIORTY1” or “PRIORTY2” is displayed on the bottom line. The selectable groups are then checked to see if any have the same ID code. If a match is found, the transceiver changes to that group. If no match is found, the group does not change and a response cannot be made on that ID code. The “Transmitting in the Scan Mode” programming described on page 39 determines if a change is temporary or permanent.
LTR FEATURES LTR FEATURES Standard and Telephone Calls Standard calls are between two mobiles or between a mobile and a control station. Telephone calls allow you to place and receive calls over the public telephone system using your transceiver. Standard calls are described starting on page 19, and telephone calls are described starting on page 21. Busy Queuing (LTR) The LTR busy queuing feature places a telephone call in a queue if the radio system is busy when it is placed.
LTR FEATURES remains enabled while in the queue mode, but system scanning is temporarily disabled. This feature is enabled on individual LTR systems by dealer programming, and it is then available with all telephone calls on that system. System Search If an out-of-range condition exists when attempting an LTR telephone call, the system search feature can be used to automatically search for a system within range. If enabled, the system search mode is automatically entered when the PTT switch is released.
CONVENTIONAL FEATURES a call is received on one of these groups, the transceiver automatically transmits a response. This causes the transceiver placing the call to briefly unsquelch and the call indicator to turn on (if it is programmed on the selected group). Priority and Block ID Codes LTR priority and block ID codes function nearly the same with both LTR and Multi-Net operation. Therefore, refer to the Multi-Net description on page 46.
CONVENTIONAL FEATURES A CG (Call Guard disable) option switch may also be programmed. This switch disables both receive and transmit squelch control on the selected group only (the monitor mode disables only receive squelch control). When squelch control is disabled by the CG switch, “CG OFF” is momentarily displayed. To re-enable squelch control and momentarily display “CG ON”, press the CG switch again, select another system/ group, or cycle transceiver power.
CONVENTIONAL FEATURES Talk-Around Normally, all transmissions go through a repeater. Therefore, if you are out of radio range of the repeater, you cannot talk to anyone, even if you are only a short distance away from the mobile you are calling. To allow communication if this occurs, the talk-around feature can be used to enable direct mobile-to-mobile communication without going through a repeater. Each selectable group can be programmed for talk-around.
CONVENTIONAL FEATURES Priority Group Sampling The priority group sampling feature ensures that messages on priority conventional groups are not missed while listening to a message on a non-priority conventional group. A fixed first and second priority group can be designated by programming or either priority group can be the selected group. When a first priority group is selected, is displayed, and when a second priority group is selected, is displayed (see following illustration).
MISCELLANEOUS NOTE: Priority sampling occurs only on conventional systems and only when scanning is enabled by the SCAN switch. It does not occur when listening to a Multi-Net or LTR call or when transmitting. MISCELLANEOUS Supervisory Tones The following tones are heard at various times when operating this transceiver. Some or all of these tones can be disabled by the TONES menu parameter or programming. Refer to “Tone Select” on page 32 for more information.
MISCELLANEOUS seconds before this tone sounds, a single beep sounds to indicate that time-out will soon occur. • Transmit Inhibit - If this tone sounds as soon as the PTT switch is pressed with a Multi-Net or LTR system selected and “TX INHIB” is displayed, the transmitter has been disabled by the Transmit Inhibit feature (see page 47).
MISCELLANEOUS Multi-Net Telephone Call Tones The following tones are generated by the Multi-Net equipment and are heard when making a telephone, unique ID, or directed group special call on a Multi-Net system. Confirmation Tone - This is a short tone that sounds when the number just dialed has been accepted by the system. Call Proceed Tone - With Multi-Net directed group calls (see page 23), ringing does not occur after the number is dialed.
MISCELLANEOUS Conversation Time-Out Tone - Calls are limited to a certain length by the system. Thirty seconds before this time is reached, a “tick” begins sounding each second. When the 30-second time expires, the call is automatically terminated by the system. Turn-Around Tone - This is a single beep which may be used to indicate to the landside party when to respond to your transmission. It sounds when you release the PTT switch, and you may partially hear this tone.
MISCELLANEOUS EMERGNCY - Indicates that the emergency switch has been pressed (see “Emergency Switch” on page 26). FCN - Indicates that the function select mode is selected by the FCN option switch (see page 28). GSCN DIS - Indicates that an attempt was made to delete a group from the scan list with group scanning disabled (see “Scan List Programming” on page 37).
MISCELLANEOUS OUT-RNGE - Indicates that the transceiver was unable to contact a repeater. Once this indication appears, no more access attempts are made until the PTT switch is released and then pressed again. Refer to “Operation At Extended Range” on page 61 for more information. PRI ON or OFF - Indicates that priority sampling was just enabled or disabled by the PRI option switch (see page 53).
MISCELLANEOUS Menu Mode Messages The following messages are displayed in the menu mode that is described starting on page 32. “ON” is displayed to indicate enabled or yes, and “OFF” is displayed to indicate disabled or no.
MISCELLANEOUS STATUS - Status message select • NO STATUS - No status message transmitted • Programmed status messages STEALTH - Stealth mode select • ON or OFF SYS SRCH - LTR system search • ON or OFF TALKARND - Conventional talk-around on-off • ON or OFF TONES - Beep tones select • SILENT - All tones disabled • KEY BEEP - Only Select switch and key press tones sound • ALERT - All tones sound except preceding Key Beeps sound • ALL TONE - All the preceding tones sound System Operator Programming As noted s
MISCELLANEOUS ground noise when messages are received. You may still be out of range even though you can hear a message. The reason for this is that the signal you are receiving is usually transmitted at a higher power level than the one transmitted by your transceiver. Communication may be improved by moving to higher ground or away from shielding objects such as tall buildings or hills.
MISCELLANEOUS Also make sure that the controls are properly set and that the power, external speaker (if used), and accessory (if used), cables are securely plugged into the back of the transceiver. If the transceiver still does not operate properly, return it to your system operator for service. NOTE: There are no user-serviceable components in the transceiver.
