Initial Installation
Power supply voltage display function
After connecting the transceiver to a power supply, the supply voltage can be confirmed by press-
ing the SQL key together with the FUNC key. The supply voltage to the transceiver is then seen on
the display.
The transceiver will return to its normal display when any key is pressed.
The display immediately changes as the voltage supply changes.
It also displays voltage during transmission.
(Example) In case of 13.6V
IMPORTANT: The range of the displayed voltage is only from 7 - 16VDC. Because the displayed
value is estimated, please use a voltmeter when a more precise reading is desired.
