A high-quality ground installation significantly
improves the performance of a mobile antenna.
Securely connect a low-resistance ground strap (or
large gauge copper wire if unavailable) from the
transceiver GND terminal to the vehicle chassis.
Clean paint or dirt from the vehicle connection point
to expose bare metal before connecting the ground.

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 the firewall, then install a rubber grommet.
2
Run the two power cable leads through the firewall
and into the engine compartment, from the
passenger compartment.
3
Connect the red lead to the positive (+) battery
terminal and the black lead to the negative (–)
battery terminal.
• Use the full length of the cable without cutting off any
excess; in particular, never remove the fuse holders.
• To prevent the risk of short circuits, disconnect other
wiring from the negative (–) battery terminal before
connecting the transceiver. Reconnect the wiring
after connecting the transceiver to the battery.
• Locate the fuse as close to the battery as possible.
4
Coil and secure the surplus cable 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.
• Ensure that the cable is isolated from heat and
moisture. If necessary, wrap heat-resistant tape
around the fuse holder to protect it from moisture.
• If using a noise filter, it should be installed with an
insulator to prevent it from touching metal on the
vehicle.
5
Connect the DC power cable to the rear of the
transceiver.
• Press the connectors firmly together until the locking
tab clicks.
Note:
◆
We do not recommend using the cigarette lighter socket, as
some cigarette lighter sockets introduce an unacceptable
voltage drop.
◆
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.

USES
If the fuse blows, determine the cause then correct
the problem. After the problem is resolved, only
then replace the fuse. If newly installed fuses
continue to blow, disconnect the power plug and
contact your dealer for assistance.
Following are the ratings for fuses used with this
transceiver:
Transceiver: 4 A (for KAT-1 antenna tuner)
DC cable:
25 A
◆
When replacing any fuse, be sure to replace it with a fuse
of the same value. Never replace a fuse with a fuse that
has a higher value.
◆
Replace blown fuses only after investigating and
correcting the cause of the failed fuse.

Place the DC cable securely within the wall of the engine
compartment. Ensure that the cable does not come into
contact with excessive heat, vapor, and/or water.
Use a rubber or plastic grommet so that the cable
does not directly touch the vehicle chassis.
