Installation
Over voltage protection
The Radio ha a high voltage input detection system, to warn you
if an overvoltage situation occurs.
Example: if the power supply voltage exceeds 17 volts DC, the
channel display (LCD backlight) will flash in 7 different colors
when the unit is turned on. In addition, when transmitting, the TX
RF power will automatically select a low power output.
If the overvoltage warning appears, you must switch your radio
off and disconnect it from the power source, before locating the
cause of the trouble. The power source must not exceed 30
volts.
Wiring Methods
There are two possible wiring configurations for connecting to
the Vehicles power supply.
A. Radio stays ON when the ignition is switched OFF
Connect the radio’s negative (black) lead to the vehicle chassis,
or directly to the batteries negative terminal.
Connect the radio’s positive (red) lead via the 2 Amp fuse to the
battery’s positive terminal. Alternatively, the positive lead could
be connected at the fuse box at a point that has +13.8Volts
continuously available (preferably the battery side of the ignition
switch) via the 2 Amp fuse.
B. Radio turns OFF with the ignition switch
Connect the radio’s negative(black) lead to the vehicle’s chassis,
or directly to the batteries negative terminal.
The radio positive(red) lead should connect to an accessory
point in the vehicle’s fuse box via the 2 Amp fuse.
