DC Power Connection
The Radio is designed for 13.8 Volt DC, negative earth installations only (i.e.
where the negative battery terminal connects to the chassis of the vehicle).
For installation on 24 volt systems an inverter (not supplied) will need to be
used.
Over voltage protection
The radio has a high voltage input detection system, to warn you if an
overvoltage situation occurs.
Eg.: If the power supply voltage exceeds 17volts DC, the channel display (LCD
backlight) will flash in 3 different colours when the unit is turned on.
In additon, when transmitting, the TX indicator 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 30volts.
