AC and DC Change-over Check
If both ac and dc input supplies are connected to the transmitter, carry out the following check:
(1) Confirm that both ac and dc supplies are connected to the transmitter. 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 transmitter is
operational.
(3) Switch off the ac supply from its source.
(4) Check that the transmitter 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.
