When AC power is disconnected, the SRG- 1250DN switches to the DC operation
and the [ DC] LED on MF/HF control panel will light up automatically.
When it is transmitted to DSC, AC signal will be changed to DC on upside of
transceiver LCD display. Moreover, changing to DC mode will be displayed on
downside of that.
And receiving output is converted to LOW.
