PREPARATION

MOBILE INSTALLATION

This transceiver allows you to install the front panel and main unit in separate locations. Select safe, convenient locations inside your vehicle that minimize danger to your passengers and yourself while the vehicle is in motion. Consider installing the units at appropriate positions so that knees or legs will not strike them during sudden braking of your vehicle. Try to pick wellventilated locations that are shielded from direct sunlight.

Note: Unlike the previous KENWOOD mobile transceivers, this transceiver does not allow the front panel and main unit to be joined.

■ Main Unit Installation

1 Install the mounting bracket in the vehicle using

the 4 supplied self-tapping screws and flat

washers.

• The bracket must be installed so that the 3 screw holes on the edge of each bracket side are facing the rear.

5 mm x 16 mm self-tapping screw

FIXED STATION INSTALLATION

MODULAR PLUG CABLE CONNECTION

When placing the main unit on a surface such as a desk

top, use the supplied cushions to prevent the surface from being scratched. Attach the 4 cushions to the base of the main unit as illustrated below.

Note: Attach the cushions to the flat surface on the main unit; otherwise the installation will be unstable and the cushions may come off easily.

Use the supplied modular plug cable to connect the front panel to the main unit. Connect the 4-pin plug to the front panel and the 6-pin plug to the main unit.

Note: The 6-pin plug is wider than the 4-pin plug.

6-pin plug

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 the transmit output power may drop excessively.

1 Route the supplied DC power cable directly to the

vehicle’s battery terminals using the shortest path from the transceiver.

• When using a noise filter, install it with an insulator to prevent it from touching metal on the vehicle.

•We recommend that you do not use the cigarette lighter socket since some cigarette lighter sockets introduce an unacceptable voltage drop.

• When routing the power cable through a hole in the vehicle chassis or body, for example in the firewall at the front of the passenger compartment, use a rubber grommet to protect the cable from abrasion. Dismantle the fuse holder to pass the cable through the firewall.

2 After the cable is in place, wind heat-resistant tape

around the fuse holder to protect it from moisture, then tie down the full run of cable.

3 To prevent the risk of short circuits, disconnect

other wiring from the negative (–) battery terminal before connecting the transceiver.

4 Confirm the correct polarity of the connections,

then attach the power cable to the battery terminals; red connects to the positive (+) terminal and black connects to the negative (–) terminal.

• Use the full length of the cable without cutting off excess, even if the cable is longer than required. In particular, never remove the fuse holders from the cable.

Red

Black

5 Reconnect any wiring removed from the negative

terminal.

6 Connect the DC power cable to the transceiver’s

power supply connector.

• Press the connectors firmly together until the locking tab clicks.

• The entire length of the cable must be dressed to isolate it from heat, moisture, and the engine secondary (high voltage) ignition system/ cables.

Fuse holder

■ Fixed Station Operation

In order to use this transceiver for fixed station

operation, you will need a separate 13.8 V DC power supply (purchased separately). We recommend using a power supply with a current capacity of 12 A.

Note:

◆ To get the most out of your transceiver, we recommend using

the optional PS-33 (20.5 A, 25% duty cycle) power supply.

◆ Before connecting the DC power supply to the transceiver, be

sure to switch the transceiver and the DC power supply OFF.

◆ Do not plug the DC power supply into an AC outlet until you

make all connections.

1 Connect the DC power cable to the regulated DC

power supply and check that the polarities are correct (Red: positive, Black: negative).

• Do not directly connect the transceiver to an AC outlet. Use the supplied DC power cable to connect the transceiver to a regulated power supply.

• Do not substitute the cable with smaller gauge wires.

2 Connect the DC power cable to the transceiver’s

power supply connector.

• Press the connectors firmly together until the locking tab clicks.

■ Replacing Fuses

If a fuse blows, determine the cause, then correct the problem. After the problem is resolved, replace the fuse. If newly installed fuses continue to blow, disconnect the power cable and contact your authorized KENWOOD dealer or an authorized KENWOOD service center for assistance.

ANTENNA CONNECTION

Before operating, you must first install an efficient, well-tuned antenna. Successful transceiver operation will depend largely on the type of antenna and its correct installation. The transceiver can give excellent results if the antenna system and its installation are given careful attention.

noitacoLesuF gnitaRtnerruCesuF

reviecsnarTA51

yrosseccAdeilppuS

elbaCrewoPCD

Only use fuses of the specified type and rating; otherwise the transceiver could be damaged.

Note: If you use the transceiver for a long period when the vehicle battery is not fully charged or when the engine is OFF, the battery may become discharged and will not have sufficient reserves to start the vehicle. Avoid using the transceiver under these conditions.

A02

Use a 50 Ω impedance antenna to match the transceiver input impedance. Also use a low-loss coaxial feed line that has a characteristic impedance of 50 Ω. Coupling the antenna to the transceiver via feed lines having an impedance other than 50 Ω reduces the efficiency of the antenna system, and can cause interference to nearby broadcast television receivers, radio receivers, and other electronic equipment.

◆ Transmitting without first connecting an antenna or other matched

load may damage the transceiver. Always connect an antenna to the transceiver before transmitting.

◆ All fixed stations should be equipped with a lightning arrester to

reduce the risk of fire, electric shock, and transceiver damage.

ACCESSORY CONNECTIONS

■ 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") mono (2-conductor) plug. For best performance, we recommend using the optional SP-50B speaker.

■ Microphone

To communicate in the voice modes, connect a 600 Ω microphone equipped with an 8-pin modular plug into the modular socket on the front of the main unit. Press firmly on the plug until the locking tab clicks.

BAND A & B

TX BAND AND CONTROL BAND

In this manual, the band recalled at the left on the display is referred to as band A, and the band at the right is called band B. In band A you can recall a 144 MHz band (default) or a 440 MHz sub-band. In band B you can recall a 440 MHz band (default) or a 144 MHz subband. You can also recall a 118 MHz, 220 MHz, or 300 MHz sub-band in band A, and a 300 MHz or 1.2 GHz in band B. This transceiver is capable of simultaneously receiving on bands A and B.

Press the left or right [BAND SEL] to select band A or B. To recall the sub-band, press [F], then the same [BAND SEL]. The following diagram shows how the bands are switched on a TM-V708A.

Note:

◆ You cannot recall a sub-band in Memory Recall mode. First press

[VFO] to select VFO mode.

◆ You cannot recall the UHF sub-band in band A and the VHF sub-

band in band B at the same time.

◆ The 118 MHz, 220 MHz, 300 MHz, or 1.2 GHz band cannot be

use for transmitting.

◆ For the range of each band, see “SPECIFICATIONS” {page 83}.

[F], right [BAND SEL]

One thing that may confuse you on this transceiver is the idea of the TX band and Control band. To avoid confusion, please note the differences between the TX band and the Control band, below.

TX Band

Press the left [BAND SEL] (band A) or the right [BAND SEL] (band B) to select. On the display, “PTT” shows

which band (A or B) is currently selected as the transmit (TX) band. You can use the TX band to transmit signals or to control the transceiver.

TM-V708

Control Band

Press [CTRL] to select. On the display, “Ctrl” shows which band (A or B) is currently selected as the Control band. Use this function when you want to control the band which is not currently set as the TX band. After selecting the Control band, you cannot control the TX band.

TM-V708

MIC KEYPAD DIRECT ENTRY (MC-58DM ONLY)

The keypad on the MC-58DM allows you to make various entries depending on which mode the transceiver is in.

In VFO or Memory Recall mode, use the Mic keypad to select a frequency {page 61} or memory channel number {page 35}. In Tone or CTCSS frequency Select mode, use the keypad to select a Tone frequency {page 28} or CTCSS frequency {page 54}. First press the Mic PF key programmed as the ENTER key {page 60}.

You can also use the Mic keypad to program a memory channel name {pages 36 and 58}, Power-on message {page 68}, or other character strings. Each press of a Mic key switches entry of characters as below. You can always use Mic [A] as [

a], [B] as [

b], [C] as [DEL],

and [D] as [OK].

OPERATING BASICS

SWITCHING THE POWER ON/OFF

1 Switch the DC power supply ON.

• If operating mobile, skip this step.

2 Press the PWR switch to switch the transceiver ON.

TM-V708

3 To switch the transceiver OFF, press the PWR switch

again.

4 If operating as a fixed station, switch the DC power

supply OFF.

•You may skip step 3. After switching the transceiver ON, you can switch it OFF or ON using only the power switch of the DC power supply.

ADJUSTING THE VOLUME

Turn the VOL control clockwise to increase the audio level and counterclockwise to decrease the audio level.

TM-V708

• If background noise is inaudible because of the Squelch function, press the Mic PF key assigned the Monitor function {page 60}, then adjust the VOL control. Press the PF key again to cancel the Monitor function.

SELECTING A BAND

Press the left [BAND SEL] to select band A, or the right [BAND SEL] to select band B.

• “PTT” moves to the selected band.

TM-V708

• For band A and B, see page 17.

SELECTING A FREQUENCY

ADJUSTING THE SQUELCH

1 Press [VFO] to select VFO mode.

TM-V708

2 To increase the frequency, turn the Tuning control

clockwise or press Mic [UP]. To decrease the frequency, turn the Tuning control counterclockwise or press Mic [DWN].

TM-V708

• Pressing and holding Mic [UP]/ [DWN] causes the

frequency to step repeatedly.

•To change frequencies in steps of 1 MHz, press [MHz] (Tuning control) first. Pressing [MHz] again cancels this function.

•To change frequencies in steps of 10 MHz, press [F]+[MHz] first. Pressing [F] cancels the 10 MHz function; pressing [MHz] starts the 1 MHz function.

When using a MC-58DM, you can also use its keypad to select frequencies. See “DIRECT FREQUENCY ENTRY (WITH MC-58DM ONLY)” {page 61}.

The purpose of the Squelch it to mute the speaker when no signals are present. With the squelch level correctly set, you will hear sound only when actually receiving signals. The higher the squelch level selected, the stronger the signals must be to receive. The appropriate squelch level depends on ambient RF noise conditions.

Turn the SQL control when no signals are present, and select the squelch level at which the background noise is just eliminated.

TRANSMITTING

1 To transmit, press and hold Mic [PTT] and speak into

the microphone in your normal tone of voice.

• “ON AIR” and the RF power meter appear.

• Speaking too close to the microphone, or too loudly, may increase distortion and reduce intelligibility of your signals at the receiving station.

• The RF power meter shows the relative transmit output power.

2 When you finish speaking, release Mic [PTT].

Time-out Timer: Holding down Mic [PTT] for more than 10 minutes

causes the transceiver to generate a beep and stop transmitting. Release, then press Mic [PTT] to resume transmitting. You can change the timer to 3 or 5 minutes {page 67}.

■ Selecting Output Power

It’s wise to select lower transmit power if communication is still reliable. This lowers the risk of interfering with others on the band. When operating using battery power, you will enjoy more operating time before a charge is necessary.

Press [LOW] to select high (“H”), medium (“M”), or low (“L”) power. The default is high.

•You can program a different output power for band A and B.

◆ Do not transmit at high output power for an extended period of

time. The transceiver could overheat and malfunction.

◆ Continuous transmission causes the heat sink to overheat.

Never touch the heat sink when it may be hot.

Note: When the transceiver overheats because of ambient high temperature or continuous transmission, the protective circuit may function to lower the transmit output power.

The Menu system on this transceiver consists of 3 levels, as illustrated below.
