Powercable; Installing Thetransceiver; Microphone - Kenwood TK-840 Instruction Manual

.
PowerCable
The power cable consists of a fused red lead, a fused black lead, and a
2-pin power plug. To install the power cable, check for an existing hole
conveniently located in the firewall through which the cable can be
passed. If no hole exists, drill the firewall and install a rubber grommet.
Starting with the plug end of the cable at the transceiver, run the two
power leads into the engine compartment from the passenger
compartment. Connect the red lead to the positive (+) battery terminal or
switched power source, and the black lead to the negative (-) battery
terminal. Always locate the fuse as close to the battery as possible. Coil
up the surplus cable and secure it out of the way with the retaining strap
provided. Ensure enough slack is available in the cables so that the
transceiver can be removed for servicing with the power applied.
CAUTION: The transceiver operates in 12 volt negative ground systems only! Always
check the battery polarity and voltage of the vehicle before installing the transceiver.
.
Installing theTransceiver
Mount the transceiver so that the controls are within easy reach of the
user. Use the mounting bracket as a template to locate the holes, then
drill the holes and mount the transceiver. Leave sufficient room at the rear
of the transceiver for cable connections. Before attaching the transceiver
to the bracket, connect the antenna connector and power plug to the
transceiver.
WARNING! For passenger safety, mount the transceiver securely so that it will not break
loose in the event of a collision. This is especially important in station wagons, vans and
similar type installations where a loose transceiver could be extremely dangerous to the
vehicle occupants.
.
Microphone
Mount the microphone hanger so that the microphone is within easy reach
of the user. Neither the microphone nor microphone cable should
interfere with the safe operation of the vehicle. After mounting the
microphone hanger, connect the microphone plug to the microphone
connector on the front of the transceiver, then place the microphone on
the hanger.
