3-2-1 Mobile Installations
Cautions :
1. Before installing the power cable, be sure to
remove the negative lead from the battery for
- Safety.
2. After installation and wiring, be sure to double
check for correct installation before reconnecting
the negative lead to the battery terminal.
3. If the fuse opens, be sure to check that each
conductor has not been damaged by short
circuiting, etc. Then replace with a new fuse of
the same rating. 7
4. After completing the wiring, wrap the fuse holder
with heat resistant tape to protect against heat
and moisture. :
5. Do not remove the fuse even if the power cable is |.

poor connection, and will result in poor performance.
Pay close attention to the polarity of the cables when
connecting them to the battery. Remember Red is

B. Ignition Noise
This transceiver has been designed to suppress ignition
noise; however, if excessive noise is present, it may be
necessary to use suppressor spark plugs (with resistors).

ENGLISH
(3-2-2
Fixed Station
A regulated DC power supply (13.8 VDC capable of
supplying at least 10 Amperes) is required. The PS-430
~ and the PS-50 are recommended.
Cautions :
1. Never connect the AC power cable to the AC outlet
until all other connections have been made.
2. Before connecting and disconnecting the power
connector, be sure to turn OFF the POWER switches
of both the transceiver and the DC power supply.
3. Observe polarity of the. DC power cable. The
transceiver operates-on 13.8 VDC, negative ground.
Battery polarity must be correct. The power cable is
color coded :
Red — + (Positive sciadty:
Black > — (Negative polarity)

less than 1.5 to 1.
Antenna
The type of antenna that is used will greatly affect the
performance of the transceiver. Use a properly adjusted
antenna, of good quality, to enable your transceiver to
perform at its best. The antenna input impedance is 50
ohms. Use 50-ohm coaxial cable such as RG-8U or 8D-2V
for this connection. If the antenna is far from the
transceiver the use of low loss coaxialcable, such as RG-
8U is recommended. Match the impedance of the
coaxial cable and that of the antenna so that the SWR is
The protection circuit in the
transceiver will activate if the SWR is particularly poor
(greater than 3 to 1).
High SWR values will cause the transmitter output to
drop, and may lead to TVI or BCI reports.
Caution :
We recommend that you install a high quality
lightening arrestor in your antenna lines — for
protection | against _ fire,electric © shock,personal
injury,or damage to the radio itself.

2. Check the frequency to see if it is occupied before
— you transmit.
3. Press the PTT switch. The ON AIR indicator will light,
and the RF meter will deflect to the right.
lf you have selected the LOW power position, the low
indicator will appear in the display and the RF meter
will only deflect slightly. When HI power has been

A lithium battery is contained in the transceiver to
retain memory.Turning off the POWER _ switch,
disconnecting the power cable,.or a power failure will
not
erase
the
memory.The
battery
should
last
for
approximately five years. When the battery discharges,
an erroneous display may appear in the display.
Lithium battery replacement should be performed by
an authorized KENWOOD service facility; either your
