PREPARATION FOR MOBILE AND FIXED STATION OPERATION 1 2 3 4 5 6 7 8 MOBILE INSTALLATION Install the transceiver in a safe, convenient position inside your vehicle that minimizes danger to your passengers and yourself while the vehicle is in motion. For example, consider installing the transceiver under the dash in front of the passenger seat so that knees or legs will not strike the radio during sudden braking of your vehicle. Try to pick a well-ventilated location that is shielded from direct sunlight.
DC POWER CABLE CONNECTION ■ Mobile Operation The vehicle battery must have a nominal rating of 12 V. Never connect the transceiver to a 24 V battery. Be sure to use a 12 V vehicle battery that has sufficient current capacity. If the current to the transceiver is insufficient, the display may darken during transmission, or transmit output power may drop excessively.
■ Fixed Station Operation 1 In order to use this transceiver for fixed station operation, you will need a separate 13.8 V DC power supply that must be purchased separately. The recommended current capacity of your power supply is 12 A. 2 3 4 1 Connect the DC power cable to the regulated DC power supply and check that polarities are correct (Red: positive, Black: negative).
■ Replacing Fuses ANTENNA CONNECTION If the fuse blows, determine the cause then correct the problem. After the problem is resolved, then replace the fuse. If newly installed fuses continue to blow, disconnect the power cable and contact your dealer or the nearest Service Center for assistance. Fuse Location Fuse Current Rating Transceiver 15 A Supplied Accessory DC Power Cable 20 A CAUTION: ONLY USE FUSES OF THE SPECIFIED TYPE AND RATING.
ACCESSORY CONNECTIONS 1 2 ■ External Speakers If you plan to use external speakers, choose speakers with an impedance of 8 Ω. The external speaker jacks accept a 3.5 mm (1/8") diameter mono (2-conductor) plug. Recommended speakers include the SP-50B and SP-41. 3 4 5 6 If you intend to use this transceiver for Packet operation, you will need the following equipment.
YOUR FIRST QSO 1 If you tend to discard instruction manuals along with the packaging material .....please don’t. The 6 steps given here will get you on the air in your first QSO right away. So, you can enjoy the exhilaration that comes with opening a brand new transceiver. After trying the rig for a while, settle back in your most comfortable operating chair with this manual and your favorite drink for an hour or two. The time spent will be worthwhile.

TRANSCEIVER GUIDE When you cannot recall how to use a function and you do not have this manual with you, you need not worry. This transceiver shows you the steps for operating the functions that you will often use. The following table lists the function indexes that you will see on the display. Function Index Ref.
OPERATING BASICS 1 2 SWITCHING POWER ON/OFF ADJUSTING SQUELCH 3 1 Switch ON the DC power supply. The purpose of squelch is to silence audio output from the speaker when no signals are present. When squelch is set correctly, you will hear sound only while a station is actually being received. The point at which ambient noise on a frequency just disappears, called the squelch threshold, depends on the frequency. • 4 5 If operating mobile, skip this step.
• SELECTING FREQUENCIES ■ Tuning Control Using the Tuning control is convenient when you are within easy reach of the transceiver front panel, and the frequencies to be selected lie near the current frequency. PWR VOL SQL 2 Turn the Tuning control to select a receive frequency. CALL You can also select frequencies via the microphone keypad (MC-53DM only). See "KEYPAD DIRECT ENTRY" {page 74}.
TRANSMITTING 1 2 ■ Selecting Output Power 1 When ready to begin transmitting, press and hold Mic [PTT] and speak in a normal tone of voice. • 3 "ON AIR" and the RF power meter appear. 4 5 It’s wise, and required by law, to select the lowest power that allows reliable communication. If operating from battery power, lower transmit power will give you more operating time before a charge is necessary. Reducing power lowers the risk of interfering with others on the band.
MENU SET-UP 1 WHAT IS A MENU? Many functions on this transceiver are selected or configured via a software-controlled Menu instead of physical controls on the transceiver. Once familiar with the Menu system, you will appreciate the versatility it offers. 3 Turn the Tuning control, or press Mic [UP]/[DWN], to select the Menu No. 2 • "CLR" and either "s" or "SET" appear as button labels. 3 • To cancel the selection and restore the previous display, press [CLR].

If the station’s signal is strong, it is best to move to a simplex frequency to continue the contact and free up the repeater. Press [REV] to toggle the Reverse function ON or OFF. • • The receive frequency and the transmit frequency are exchanged.
MEMORY CHANNELS 1 2 3 4 5 6 In memory channels, you can store frequencies and related data that you often use. A total of 280 memory channels are available, 140 each for VHF and UHF. You can also store a name for each memory channel. Using this naming function restricts the total number of memory channels to 180, but allows you to select the ratio of channels between the VHF and UHF bands, from among 5 types. For more information, see "NAMING MEMORY CHANNELS" {page 32}.
3 Press [s], then select item No. 2 (Channel Ratio). VHF/UHF MEMORY CHANNEL RATIO 1 You can change the ratio of memory channels between the VHF and UHF bands, from the factory default (90 channels each). Changing the ratio requires all memory channels to be cleared. So decide the appropriate ratio before storing data in memory channels. The selectable ratios are as shown below: CALL PWR 2 VOL 3 SQL 2 4 1 5 4 Press [SET], then select the desired ratio.
1 2 3 4 STORING DATA IN SIMPLEX CHANNELS STORING DATA IN SPLIT CHANNELS 1 Select the desired band. 1 To select the desired receive frequency, related data and memory channel, use steps 1 to 4 (not 5) given for Simplex Memory Channels. 2 Select the desired frequency and related data (Tone, CTCSS, DTSS, etc.) using VFO mode, Memory Recall {page 31}, or the Call channel {page 33}. 3 Press [F]. 5 6 • A memory channel number and an arrow appear.

When you recall a named memory channel, its name appears on the display with the stored frequency. Names can be callsigns, repeater names, cities, names of people, etc. The first digit blinks. CALL PWR VOL Note: ◆ You cannot use this function after having selected 140:140 memory channel ratio. ◆ You cannot name the Call, L1 to L3, nor U1 to U3 channels.
CALL CHANNEL ■ Recalling the Call Channel The Call channel can be used to store any frequency and related data that you will recall often. The Call channel can be programmed with a simplex or split frequency as well as related data that can be stored in the memory channels. No matter what mode the transceiver is in, the Call channel can always be selected quickly. You may want to dedicate the Call channel as an emergency channel within your group. In this case, the Call/VFO scan {page 48} will be useful.
■ Changing Call Channel Contents (Split) MEMORY a VFO TRANSFER 1 1 Select the desired band. 2 2 Select the desired receive frequency and related data (Tone, CTCSS, DTSS, etc.) using VFO mode or Memory Recall {page 31}. Transferring the contents of a memory channel or the Call channel to the VFO can be useful if you want to search for other stations or a clear frequency, near the selected memory channel or Call channel frequency. 3 Press [F], [CALL] (1 s).
INITIALIZING MEMORY ■ Partial Reset (VFO) If your transceiver seems to be malfunctioning, initializing the transceiver may resolve the problem. Remember that initializing the memory channels requires that you re-enter memory channel data again after the initialization. On the other hand, initialization is a quick way to erase all data from all channels. Note: While using the Channel Display or All Lock function, you cannot do Partial Reset nor Full Reset. VHF Band Defaults Version U.S.A.
PROGRAMMABLE MEMORY (PM) 1 2 3 4 5 6 Programmable Memory (PM) allows you to store virtually all settings currently set on the transceiver. So you can quickly recall exactly the same environment later. This transceiver provides 4 PM channels. If you are the type who likes the many features offered by modern transceivers, but dislikes remembering how to make all the necessary settings, you will find Programmable Memory particularly useful.
APPLICATION EXAMPLES Situation 2: The following are examples of how you might use Programmable Memory. These examples may not represent applications useful to you, but you will understand the flexibility of this function. While operating mobile on the way to work every morning, you prefer a silent transceiver that does not interrupt the morning calm. In addition, you feel that a bright display is a waste of electricity in sunlight.
1 2 STORING DATA IN PM CHANNELS RECALLING PM CHANNELS 1 Confirm that the following conditions have been satisfied: 1 Press [PM]. 3 4 5 6 7 8 9 • Both bands are in the receive mode. • Scan is not being used on either band. • Microphone Control is OFF.

Use the following procedures to activate this function: 1 Press [CALL]+ POWER ON. 1 2 3 • A confirmation message appears.
SCAN 1 2 3 4 5 6 Scan is a useful feature for hands-off monitoring of your favorite frequencies. After becoming comfortable with how to use all types of Scan, the monitoring flexibility gained will increase your operating efficiency. This transceiver provides the following conventional scans in addition to “Visual Scan” {page 41} that may be new to you.
VISUAL SCAN ■ Selecting the Number of Channels While you are on the air, Visual Scan allows you to monitor frequencies near the current operating frequency. Visual Scan graphically and simultaneously shows how all frequencies in the selected range are busy. You will see up to 14 segments, for each channel, that represent 7 S-meter levels (2 segments per level). You determine the scan range by selecting the center frequency and the number of channels. The default number of channels is 49.
■ Using Visual Scan 1 1 Select the desired band. 2 2 Turn the Tuning control, or press Mic [UP]/[DWN], to select the operating frequency. 3 • 4 5 This frequency will also be used as the center frequency. 3 Press [F], [VISUAL] to start Visual Scan. 6 • 7 To halt Scan, press [PAUSE]. "P" appears. Press [PAUSE] again to resume. 8 9 10 11 4 To change the operating frequency, turn the Tuning control or press Mic [UP]/[DWN]. 12 13 • The displayed frequency changes and the cursor moves.
SCAN RESUME METHODS Before using Scans other than Visual Scan, it’s necessary to decide under what condition you want your transceiver to continue scanning after detecting and stopping for a signal. You can choose Time-Operated mode or Carrier-Operated mode. The default is Time-Operated mode. • Time-Operated mode Your transceiver stops scanning after detecting a signal, remains there for approximately 5 seconds, and then continues to scan even if the signal is still present.
1 2 3 4 VFO SCAN MEMORY SCAN VFO Scan allows you to scan all frequencies from the lowest frequency to the highest frequency on the band. The current frequency step size is used. Memory Scan allows all memory channels containing data to be scanned. 1 Select the desired band. 2 Press [VFO] (1 s). 5 6 7 8 • The 1 MHz decimal blinks while scanning is in progress. • Scan starts at the frequency currently displayed. 3 To reverse the scan direction, turn the Tuning control or press Mic [UP]/[DWN].

When scanning the TX band, you can also press Mic [PTT] to quit Scan.
CONTINUOUS TONE CODED SQUELCH SYSTEM (CTCSS) 1 CTCSS uses a subaudible tone to control the squelch of transceivers, and by this system you can reject signals from undesired stations. Suppose that only stations "A", "B", and "C" are programmed with the same tone frequency. The squelch in “A” opens only when called by “B” or “C”. USING CTCSS 2 Repeatedly press [TONE] until "CT" appears. Each time you press [TONE], the selection changes as shown below.
DUAL TONE SQUELCH SYSTEM (DTSS) 1 3 4 5 6 7 8 9 DTSS provides a more refined method than CTCSS to selectively communicate with specific stations. The squelch on the transceiver opens only when the same 3-digit DTMF (Dual Tone Multi-Frequency) code is received that is programmed in this transceiver. You can select a 3-digit code from among 1000 combinations, 000 to 999. Note: ◆ Be aware that audible DTMF tones from other transceivers near you may be picked up by your MC-53DM or MC-45 microphone.
USING DTSS 1 Select the desired band. 2 Press [F], [DTSS] to switch the DTSS function ON. • "DT" appears. Note: ◆ DTSS may not function in the following situations: • The other station is using a battery saver function. • A repeater ID and the DTSS code are received simultaneously. If difficulty is experienced in these cases, press [MR] while in the transmit mode. The DTSS code is re-transmitted. ◆ DTSS cannot be used with some repeaters.
■ DTSS and Repeaters 1 Pressing Mic [PTT] transmits the DTSS signal after a short delay. When using repeaters with long response times, this delay helps the repeater avoid losing a portion of the DTSS code. The delay time is 350 ms during simplex operation. 2 3 4 When using a transmit offset or a split frequency, you can select either 350 ms (default) or 550 ms. 5 6 1 Press [MNU] to enter Menu mode. 7 2 Select Menu No. 12 (Code Squelch).
PAGE 1 Page also uses DTMF codes to address specific stations. When your transceiver transmits a DTMF code, the squelch of only the transceivers that have the same code programmed, opens. Unlike DTSS, Page allows you to choose whether you will call a single station or a group of stations. In addition, Page offers the added benefit of identifying who called you. When you are called with your Station code, the calling station’s code appears on the display. If called with a Group code, the Group code appears.
5 Press [s]. STORING PAGE CODES 1 2 3 4 Note: Page does not function while you are storing Page codes even if a code is received that matches one already stored in memory. 1 Select the desired band. 2 Press [F], [DTSS] twice to switch Page ON. • • The first digit blinks. • To quit selection, press [OFF]. 6 Use the Tuning control or Mic [UP]/[DWN] to select the first digit. • "PAG" appears. 5 7 Press [s]. 6 • 7 9 • If DTSS is already ON, press this key combination once.
CALLING RECEIVING Note: Before making a call, store your Station code in channel A, and store the desired Station codes or Group codes in channels 1 to 5. 1 Select the desired band, and tune to the prearranged frequency. 1 Select the desired band. 2 Tune to the prearranged frequency. 3 Press [F], [DTSS] twice to switch Page ON. • "PAG" appears. • If DTSS is already ON, press this key combination once. 4 Press [F] (1 s), [C.SEL]. 1 2 2 Switch Page ON. 3 3 You are ready to receive a call.
1 2 3 4 5 6 7 8 9 Note: ◆ If, after Page has opened the squelch, no signal is received for more than 2 seconds, the squelch will close. ◆ "Err" appears on the display if your transceiver fails to receive the Page code correctly. ◆ Page may not function in the following situations: • The other station is using a battery saver function. • A repeater ID and the Page code are received simultaneously. If difficulty is experienced in these cases, press [MR] while in the transmit mode.
AUTO PAGE CANCEL PAGE ANSWER BACK (U.S.A./ CANADA ONLY) After successfully paging another station, switching Page OFF eliminates sending a Page code each time you transmit. Auto Page Cancel automatically handles this situation when a station you called responds using the correct Page code. Page Answer Back informs the other station that you received the Page call. Your transceiver sends the answer back signal only when receiving your station code or a correct Group code.
DUAL TONE MULTI-FREQUENCY (DTMF) FUNCTIONS 1 2 3 4 5 The following DTMF functions require the MC-53DM or MC-45DM (option) microphone. The keypad on the microphone includes the 12 keys found on a push-button telephone plus an additional 4 keys (A, B, C, D). These additional keys are required for various control operations by some repeater systems. 6 7 8 9 MAKING DTMF CALLS 2 Press the keys in sequence on the keypad to send DTMF tones. 10 • The corresponding DTMF tones are transmitted.
