r Getting Started Antenna To attach the antenna to the TNC connector on top of your radio, press down and rotate the antenna base clockwise until it seats firmly into place. Battery Information The Sundowner UH-O57 comes with a standard rechargeable Ni-Cd Battery Pack. An optional heavy duty rechargeable Ni-Cd Battery Pack is also available. Installation THE RECHARGEABLE NICKEL-CADMIUM BATTERY PACK MUST BE CHARGED FULLY BEFORE USING IT FOR THE FIRST TIME.
-- - ~----- Recharging the Nickel-Cadmium Battery Pack Note: Before charging, be sure that the power (ON/OFF Volume control) is turned OFF. Recharge the Ni-Cd Battery ONL Y when the unit indicates a LOW BA TTERY condition. (TX LED blinks during TRANSMIT) Insert the discharged Battery Pack in the rapid charger, or connect the trickle charger to the side of the unit. Using the trickle charger, the standard pack charges fully in 8 hours, and the heavy duty pack in 12 hours.
~-.... rI , ! i Operation I --11 RECEIVE 1. Turn the radio ON. Rotate the ON/OFF Volume control clockwise until you hear the click. A channel number should appear in the LCD Display. UP DOWN 2. Press the 0 or 0 switch or use the Numeric Keypad to select the desired channel. 3. Press the monitor switch (Auto-squelch turns OFF). 4. Rotate the ON/OFF Volume control to adjust the speaker volume to a comfortable level. 5. Press the Monitor switch (Auto-squelch turns ON).
r Channel Scan I I i UP When you pressed the 0 Key for more than 1.5 seconds, the scan feature starts and the SCN indicator appears on the LCD. Scanning stops automatically on any active channel that is not Locked-out, receives a call and you hear the caller. UP To resume scanning, press the 0 Key. If there is too much activity on a certain channel and you wish uo to exclude it from being scanned, simply press the Key (please see page 18 on how to create a channel scan list).
r' Priority Scan When a priority channel is selected and scan is activated, the radio will monitor the prioritised channel regularly for activity while scanning. While scanning, if a signal is received on the priority channel the radio will stay on that channel as long as the signal is present. Otherwise, priority scanning resumes after 3 seconds.
r Create a Channel Scan List with Channel Lock-Out Feature You may have certain channels that you do not want to hear every time you scan. These are channels that are busy in a major portion of time, and the scanning stops at that channel(s) often enough to interrupt the scan cycle. You can Lock-out those channels so they are not scanned. There are two ways to do this. UP 1. Using the 0 DOWN or 0 switches, manually select the uo desired channel and press the button. The lockedout channel blinks.
"., I r TRANSMIT 1. The maximum transmit power output level of UH-O57is 5 watts. To switch to Iow power, press the HI/LO switch. LO appears on the LCD and the transmit power output level is changed to 1 watt. To switch back to High power, press the HI/LO switch again. The TX power returns to high and the LO indicator disappears from the LCD. 2. Before you transmit, listen for activity on the selected channel. 3. When the channel is clear, press the PIT switch to transmit.
! '--' ,~- -_....--------- r Simplex I Duplex Communication Duplex Operation allows the Uniden Sundowner UH-O57 to operate via a repeater station on Channels 1 through 8. The set receives on these channels but transmits on Channels 31 through 38 respectively. When Duplex operation is disabled, the set receives and transmits on the same channel. (Simplex Communication) To activate Duplex operation on a Channel where Repeater Service is available, select the channel and then press the DUP 0 button.
Special Feature SELECTIVE CALLING Selective Calling (SELCALL) is a special Sequential Tone Squelch System that allows the user to receive/transmit calls selectively fromlto an individual or a group, on a shared busy channel. The Sundowner UH-O57 has Selective Calling (SELCALL) system specially built-in. With exceptional features like Receiver Quieting, Group Calling, and User Programmable Parameters makes the Sundowner UH-O57 superior to any of its kind.
rSELCALL OPERATION Receiver Quieting Puts the receiver on "Quiet" Mode (also known as "Tone Squelch" Mode). When enabled, the radio prevents any unwanted conversations in the channel from being heard unless the call is specifically directed to you and the required SELCALLID to open the "Quiet" condition is received. To enable: 1. Select the channel you want to put in Quiet Mode using either the UP/DOWN Switch or the Numeric Keypad.
When a call is received... While on TSO Condition, when UH-057 receives a code matching your SELCALL ID, it will do the following operation. 1. Automatically Acknowledge 2. responds to the caller by transmitting tones. Informs you that a caller is on the channel by emitting a CALL ALARM (three successive tones in a regular interval for 10 seconds.) and displays the CAL indicator. 3. Flashes the TSO indicator for about 20 seconds allowing you to use the PTT Switch.
~ When a call is received while TSQ Scanning, UH-057 follows the same response as receiving a call on a Tone Squelch Channel. It differs only on the following. 1. If the call is not answered within the 20 second period, TSQ Scanning resumes. CAL indicator remains on the LCD. To look for the channel where CALL is received: UP a. Cancel TSQ Scanning by pressing either the DOWN 0 Key. UP 0 or DOWN b. Using the 0 or Channels.
-.. ..----- Tone Calling Tone calling enables you to selectively call other radios. To do this, the SELCALL ID of the radio you are going to call should be in the Transmitters SELCALL ID memory (please see Programming Method on page 28). To Call: 1. Select the channel where you and your group agreed to use for Selective Calling. 2. Press and hold the @ Key for about 1.5 seconds.
--".. "'- where: [x] is a common SELCALL ID prefixes of your group and, [A] is the internationally assigned SELCALL tone to identify the Group Call Code example: If one group comprises of 1D members with SELCALL 10s. ranging from [1] [2] [1] [2] [1] [2] [1] [2] to [3] [4] [D], [3] [4] [1], [3] [4] [2], [3] [4] [3], [1] [2] [3] [4] [9], All in TSO Mode at CH2D If someone transmits [1] [2] [3] [4] [A] on CH2D, all of the above unit will open their Tone Squelched Receiver.
Programming Since UH-O57 can support either 5 tone or 6 tone signalling format, you and your group must decide which format are you going to use. Receiver SELCALL ID To program your own receiver SELCALL ID, do the following procedure. 1. Press and hold the @ Key for about 1.5 seconds. Two beeps will be heard and the LCD displ~ys: - -] [ 2. Press the @ Key. The TSQ indicator appears on the LCD Display. Flashing. " , , q~:, I ' GIlD - 3. Enter your chosen SELCALL ID using the Numeric Keypad.
4. Press the (@) Key to complete the programming. Two beeps will be heard and the unit returns to its previous status prior to accessing Programming Mode. If you decided to use the 6 Tone Format, simply enter the sixth digit when programming before pressing the(@) Key. To remove the Receiver SELCALL ID from Memory: 1. Follow step 1 and 2 of Receiver SELCALL ID programming. 2. Press the @}) Key. Programming ends and no ID will be stored in the memory. Whenever the @ Key is pressed, error tone will be heard.
3. Enter the Transmitter SELCALL ID using the Numeric Keypad. Example: 1 2346 Every time you press the numeric Keypad, confirmation tones will be heard. The SELCALL Tone assigned to the pressed Keypad will be displayed on the LCD as shown: (please see page 34 for the SELCALL TONE Key Assignment) CD tcAL / I,
Other SELCALLParameters. Aside from the Transmitter and Receiver ID, you should also know some of the SELCALL Parameters. Though, this parameters are not frequently changed understanding them will probably help you on your future use. Tone Period Tone Period is the duration of one tone in a SELCALL ID sequence. The setting of this parameter depends on your application.
For example, selecting 40 mSec Press CD. The lCD displays PI [ ] 3. Press the @ Key to complete the programming. Two beeps will be heard and the unit returns to its previous status prior to accessing Programming Mode. Lead-In Delay lead-In delay is a SElCAll transmit parameter that "wakes-up" and helps the receiver of the other radio to lock onto the incoming signal.
