HIGH VOLTAGE DETECTION
The radio has a built-in, high voltage detection system to warn you if an over
voltage situation occurs. If the power supply voltage exceeds 18 volts DC, the
display will flash ‘High DC’ for 1 second and will sound a warning beep. If you are
transmitting, ‘High DC’ will be displayed and the output power will be reduced to
1 watt.
If the ‘High DC’ warning appears you should switch your radio OFF and disconnect
it from the power source, before locating the cause of the trouble.
NOTE
: The High DC warning will remain on the display even if the normal voltage
level is restored. You will need to switch the radio OFF then ON again to reset it
and clear the ‘High DC’ warning.
IMPORTANT
:
The power source should never exceed 30 volts.
