3. Initial Installation
External power supply control & power lamp functions
=> ACC terminal
Cigar-Plug connection
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-43 (for a Cigar-Plug connection. EDC-36 is also
compatible) cable. Connect one of the cables between the ACC terminal or a Cigar-Plug that oper-
ates 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:
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 igni-
tion 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 SmA.
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. f] ts

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.
