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.
