Mobile Operation
In some cars,the 12V plug is always powered. If this is the case, you cannot
use it for the ignition key on/off function.
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.
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.
1.
Route the DC power cable supplied with the transceiver directly
to the vehicle's battery terminals using the shortest path from the
transceiver.
We recommend you do not use the cigarette lighter socket as some
cigarette lighter sockets introduce an unacceptable voltage drop.
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
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 remove negative (-)
terminal 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.
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.
5.
Reconnect any wiring removed from the negative terminal.
optional 12V Plug cable. Connect one of the cables between the ACC
terminal or a 12v Plug that operates with the vehicle ignition or ACC
switch on the vehicle and EXT POWER jack on the rear side of the
unit.
Locate the power input connector as close to the transceiver as possible.
