AC and DC Change-over Check
If both ac and dc input supplies are connected to the transceiver, carry out the following check:
(1) Confirm that both ac and dc supplies are connected to the transceiver. Ensure that the rear panel
Power switch is set to the I (on) position.
(2) Confirm that the front panel Ready indicator is lit, the LCD is illuminated, and the transceiver is
operational.
(3) Switch off the ac supply from its source.
(4) Check that the transceiver continues to operate correctly from the dc supply. If accessed, the
front panel BIT screen will show AC Supply as off and DC supply as on. The value of the dc
supply is also shown.
