KENWOOD TK-D740 VHF Digital Transceiver

PREPARATION

Various electronic equipment in your vehicle may malfunction if they are not properly protected from the radio frequency energy which is present while transmitting. Typical examples include electronic fuel injection, anti-skid braking, and cruise control. If your vehicle contains such equipment, consult the dealer for the make of vehicle and enlist his/her aid in determining if they will perform normally while transmitting

Connecting the power cable

The transceiver operates in 12 V negative ground systems only! Check the battery polarity and voltage of the vehicle before installing the transceiver

1. Check for an existing hole, conveniently located in the firewall, where the power cable can be passed through.
   • If no hole exists, use a circle cutter to drill a hole, then install a rubber grommet.

2. Run the power cable through the firewall and into the engine compartment.

3. Connect the red lead to the positive (+) battery terminal and the black lead to the negative (–) battery terminal.
   • Place the fuse as close to the battery as possible.

4. Coil the surplus cable and secure it with a retaining band.
   • Be sure to leave enough slack in the cables so the transceiver can be removed for servicing while keeping the power applied.

Installing the Transceiver

For passenger safety, install the transceiver securely using the supplied mounting bracket and screw set so the transceiver will not break loose in the event of a collision.

Note:

◆ Before installing the transceiver, check how far the mounting screws will extend below the surface. When drilling mounting holes, be careful not to damage vehicle wiring or parts

1. Mark the position of the holes in the dash, using the mounting bracket as a template. Using a 4.2 mm (5/32 inch) drill bit, drill the holes, then attach the mounting bracket using the supplied screws.
   • Mount the transceiver within easy reach of the user and where there is sufficient space at the rear of the transceiver for cable connections.

2. Connect the antenna and the supplied power cable to the transceiver.

3. Slide the transceiver into the mounting bracket and secure it using the supplied hex-headed screws.

4. Mount the microphone hanger in a location where it will be within easy reach of the user.
   • The microphone and microphone cable should be mounted in a place where they will not interfere with the safe operation of the vehicle.

When replacing the fuse in the DC power cable, be sure to replace it with a fuse of the same value. Never replace a fuse with one that is rated with a higher value.

PTT ID
PTT ID is the transceiver unique ID code which is sent each time the PTT switch is pressed and/or released.
Note:
◆ PTT ID can be made only in analog operation.
SIGNALING
QT/ DQT
The Encoder/Decoder function uses QT/ DQT to segregate talk groups, so users only hear calls from their own group.
DTMF
A DTMF PTT ID is included for dispatch operations or simple remote control applications. The DTMF decode capabilities include Selective Call ID, Transpond with ID, and “Wild Card” Group Calling.
2-Tone
2-tone Signaling opens the squelch only when your transceiver receives a call containing matching 2 tones.
5-Tone
5-tone Signaling opens the squelch only when the transceiver receives the 5 tones programmed in your transceiver. Transceivers that do not transmit the correct tones will not be heard.
COMPANDER
If programmed by your dealer for a channel, the compander will remove excessive noise from transmitted signals, to provide higher clarity of signals.
Note:
◆ The compander is used only in analog operation.
VOICE ANNUNCIATION
If enabled by your dealer, when changing the zone and channel, an audio voice will announce the new zone and channel number.
