3. Initial Installation
Connect the microphone to the front panel of the transceiver.
Connect antenna port to a 50 ohm antenna that covers the two-meter band, using good quality
50 ohm coaxial cable.

For a base station set up
The Transceiver requires a 12-13.8VDC negative grounded power source.
Use a regulated power supply capable of providing continuous current of 12A or more.
Power supplies that do not meet those specifications may cause malfunction and/or damage to the
radio and will void the warranty. Alinco offers excellent communication-grade power supplies as
optional accessories. Please contact your local authorized Alinco dealer.

Location
The transceiver may be installed in any position in your car, where the controls and microphone are
easily accessible and it does not interfere with the safe operation of the vehicle or the performance
of the set. If your vehicle is equipped with air bags, be certain your radio will not interfere with
their deployment. If you are uncertain about where to mount the unit, contact your vehicle's manufacturer.
Installing a Mobile Antenna
Screw-fixed
base
Magnet base
Use a 50 ohm coaxial cable to connect the antenna. Mobile antennas require an appropriate mounting base for proper installation and operation. For more information, see the documentation for
your antenna.
CAUTION: After installing your antenna, ensure that you have the best possible SWR reading.
High RF environments can cause severe damage to your unit. Ensure that you are not
in a high RF environment when operating the transceiver.

3. Initial Installation
External power supply control & power lamp functions
ACC terminal
Ext. Power jack
DC cable
Be sure the vehicle has a negative-ground, 12VDC electric system before installation. Connect the
provided DC cable directly to the battery as shown below to minimize any possible ignition noise.
Be sure the vehicle has a large capacity battery as the use of the transceiver may overload the
electric system of the vehicle.
If the ignition-key on/off feature is desired (optional feature), use the optional EDC-37 (For direct
connection to the circuit on the vehicle) or EDC-36 (for a Cigar-Plug connection) cable. Connect
one of the cables between the ACC terminal or a Cigar-Plug that operates with the vehicle ignition
or ACC switch on the vehicle and EXT POWER jack on the rear side of the unit. (Note: In many
cars, the cigar-lighter plug is always powered. If this is the case, you cannot use it for the ignition
key on/off function.) If this option is selected, the unit can be turned on/off either manually or
automatically in accordance with the ignition key position:
Cigar-Plug connection
Battery
1. When the ignition key is turned to ACC or ON (Start) position with the radio turned
off, the power switch illuminates. The illumination will be turned off when the ignition key is turned to the off position. To turn on the unit, press the power switch
manually while it is illuminated (while ignition key is at ACC or ON position).
2. When the ignition key is turned to ACC or ON position with the radio's power switch
on, the unit turns on automatically and the power switch will be lit. Turn the ignition
key to OFF position or manually turn the power switch off to shut down the radio.
The power consumption when using the additional cable is 5mA.
For operation without this option, use the power switch to turn the unit on/off.
Power supply voltage display function
After connecting the transceiver to the power supply, the supply voltage can be confirmed by
pressing the SQL key together with the FUNC key. The supply voltage to the transceiver is then
seen on the display.
The transceiver will return to its normal operation when the power is switched OFF.
The display immediately changes as the voltage supply changes.
It also displays voltage during transmission.
IMPORTANT:
The range of the displayed voltage is only from 7V - 16VDC. Because the displayed value
is estimated, please use a voltmeter when a more precise reading is desired.

PWR key
Turning the unit on and off
Press the power switch or turn the ignition key to ACC or ON
position according to the option selected during installation.
Press the power switch again or turn the ignition key to OFF
position to turn off.
Audio Volume level setting
Rotate the VOL knob clockwise to increase the audio level,
counterclockwise to decrease. Set it at the desired level.
Squelch level setting
A squelch eliminates white-noise (the background noise when
a signal is not received).
Higher level settings will keep the squelch “closed” more
tightly for quieter monitoring, but weak signals will not be
heard. Lower settings allow weaker signals to “open” the
squelch but noise may also cause it to open.
1. Press SQL key. SQL icon appears on the dis-
play and the squelch level will be shown at the
position where the memory number is displayed. 21 levels, between 0 and 20, are available. “0” is the lowest setting.
2. By rotating the main dial or by using the UP/
DOWN keys on the microphone, adjust the
squelch to the desired level. To return to normal use, press PTT or any key on the front
panel; or if there are no operations within 5
seconds, the unit will store the setting and will
return to its original status.
