Radio turns OFF with the ignition switch:
connect the radio's negative (black) lead to the vehicle's
chassis, or if preferred, directly to the battery's
negative terminal.
the radio's positive (red) lead should connect to an accessory
point in the vehicle's fuse box via the 2 amp fuse. this point
should supply +13.8 volts only when the ignition switch is
turned on or in the AccEssory position.
high Voltage warning
the tX3340 has a built-in, high voltage detection system to
warn you if an overvoltage situation occurs.
if the power supply voltage exceeds 18 volts dc, the channel
display will flash ‘hi dc’ for 5 seconds when the unit is first
turned on, or at the time the voltage exceeds 18 volts. in
addition, when transmitting, the tX indicator will flash and the
transmitter will select low output power.
if the overvoltage warning appears you should switch your
tX3340 oFF and disconnect it from the power source, before
locating the cause of the trouble.
once the high voltage warning has been triggered, and you
have fixed the source of the problem, you will need to switch
the tX3340 oFF then on again to reset it.
the power source must not exceed 25 volts otherwise
permanent damage may occur to your radio, which may not
be covered by the manufacturer’s warranty.
