Initial Installation

DC Power Cable Connection

Mobile Operation
The vehicle battery must have a nominal rating of 12V. Never
connect the transceiver to a 24V battery. Be sure to use a 12V
vehicle battery that has sufficient current capacity. If the current
to the transceiver is insufficient, the display may darken during
transmission, or transmitting output power may drop excessively.
1. Route the DC power cable supplied with the transceiver directly
to the vehicle's battery terminals using the shortest path from the
transceiver.
Never use the cigarette lighter socket as a DC source.
The entire length of the cable must be dressed so it is isolated from
heat, moisture, and the engine secondary (high voltage) ignition
system/ cables.
2. After installing cable, in order to avoid the risk of damp, please
3
use heat-resistant tap to tie together with fuse box. Don't forget to
reinforce whole cable.
3.
In order to avoid the risk of short circuit, please cut down
connection with negative (-) of battery, then connect with radio.
4. Confirm the correct polarity of the connections, then attach the
power cable to the battery terminals; red connects to the positive (+)
terminal and black connects to the negative (-) terminal.
Never remove the fuse holders from the cable.
5.
Reconnect any wiring removed from the negative terminal.

If the ignition-key on/off feature is desired(optional feature), use the
optional EDC-43(For 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.
7. 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)

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.
9. Use of ignition-key ON/OFF feature drains 5mAh of current from
the battery as long as the EDC-43 is being connected.
