high Voltage WarNiNg
the tX3420 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
tX3420 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 tX3420 off then on again to reset it .
the power source must not exceed 30 Volts .
