PREPARATION FOR MOBILE OPERATION
When operating mobile, do not attempt to configure
your transceiver while driving because it is simply too
dangerous. Stop the car first, then make the necessary
changes. Also, be aware of local laws pertaining to the
use of headphones/headsets while driving on public
roads. If in doubt, do not wear headphones while
mobiling.
MOBILE INSTALLATION
Install the transceiver in a safe, convenient position
inside your vehicle that minimizes danger to your
passengers and yourself while the vehicle is in motion.
For example, consider installing the transceiver under
the dash in front of the passenger seat so that knees or
legs will not strike the radio during sudden braking of
your vehicle. Try to pick a well-ventilated location that
is shielded from direct sunlight. Leave sufficient space
behind the Rear Panel for the transceiver fan to
exhaust warm air.
gw Installation Example
1 Install the mounting bracket using the supplied
flat washers and self-tapping screws. There are
4 washers and 4 screws supplied.
The bracket can be mounted with the bracket
opening for the transceiver facing down for
underdash mounting, or with tne opening
facing up. Study the accompanying diagram
to determine the best installation method for
your situation.

Se | yy | °O- SEMS screw

2 Position the transceiver in the bracket to
determine the best viewing angle.
3 Insert and tighten the supplied hexagonal SEMS
screws and washers. There are 2 screws and 2
washers supplied for each side of the bracket.
* Double check that all hardware is tightened to
prevent vehicle vibration from loosening the
bracket or transceiver.
DC POWER CABLE CONNECTION
Route the DC power cable supplied with the transceiver
directly to the vehicle's battery terminals using the
shortest path from the transceiver. If using a noise
filter, it should be installed with an insulator to prevent it
from touching metal on the vehicle. It is not
recommended to use the cigarette lighter socket since
some cigarette lighter sockets introduce an
unacceptable voltage drop.
To prevent the risk of short circuits, disconnect other
wiring from the negative (—) battery terminal before
connecting the transceiver. Confirm the correct polarity
of the connections before attaching the power cable;
red connects to the positive (+) terminal, 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. After completing
Battery

transceiver connections to the battery, then reconnect
any wiring removed from the negative terminal.
If the power cable must be routed 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. The entire
length of the cable must be dressed so it is isolated
from heat and moisture. After the cable is in place,
wind heat-resistant tape around the fuse holder to
protect it from moisture. Tie down the full run of cable.
Dismantle the fuse holder to pass
the cable through the firewall.
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 transmit output power may drop
excessively.
Only after completing the installation, connect the
transceiver's power supply connector to the DC power
cable. Press the connectors firmly together until the
locking tab clicks.
m@ Replacing Fuses
If the fuse blows, determine the cause then correct
the problem. After the problem is resolved, then
replace the fuse. If newly installed fuses continue to
blow, disconnect the power cable and contact your
dealer or the nearest Service Center for assistance.

CAUTION: Only use fuses of the specified type and rating.
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.

ANTENNA CONNECTION
Before operating mobile, you must first install an
efficient, well-tuned antenna. The success of your
mobile installation 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 is given careful attention.

DC POWER SUPPLY CONNECTION
In order to use this transceiver for fixed station
operation, you will need a separate 13.8 V DC power
supply that must be purchased separately. 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 a cable
with smaller gauge wires. The recommended current
capacity of your power supply is 12 A.
First connect the DC power cable to the regulated DC
power supply and check that polarities are correct
(Red: positive, Black: negative). Then connect the
transceiver's DC power connector to the connector on
the DC power cable. Press the connectors firmly
together until the locking tab clicks.

Note:
For your transceiver to fully exhibit its performance capabilities,
the following optional power supply is recommended:
PS-33 (20.5 A, 25% duty cycle).
¢ Before connecting the DC power supply to the transceiver, be
sure to switch the transceiver and the DC power supply off.
¢@ Donot plug the DC power supply into an AC outlet until you make
all connections.
m@ Replacing Fuses
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 or the nearest Service Center for
assistance.

CAUTION: Only use fuses of the specified type and rating.
ANTENNA CONNECTION
The type of the antenna system, consisting of the
antenna, ground, and feed line, will greatly affect the
successful
performance
of
the
transceiver.
Use
a
properly adjusted 50 Q antenna of good quality
designed
for
operation
at
your
operating
frequency
to
let your transceiver perform at its best.
Install
low-loss
50
Q
coaxial
cable
and
a
first
quality
connector
for
the
connection
to
the
transceiver.
For
longer
feed
line
runs,
especially
for
operation
at
UHF
frequencies,
you
might
consider
investing
in
"hardline"
transmission
line.
Hardline
is
available
in
larger
diameters
and
has
much
lower
loss
than
coaxial
cable.
The
lower
loss
can
make
a
significant
difference
for
those
interested
in
weak
signal
operation.
In
all
cases,
match
the
impedance
of
the
feed
line
and
antenna
so
that
the
SWR
is
minimum.
Generally,
an
SWR
measurement
of
1.5:1
or
less
is
considered
satisfactory.
All
connections
must
be
clean
and
tight.
Coupling
the
antenna
to
the
transceiver
via
feed
line
having
an
impedance
other
than
50
Q
reduces
the
efficiency
of
the
antenna
