NOTES:
1. This feature is dependent upon installation, but
typically only one side’s COM and NAV is wired for
ON--OFF controls. The COM and NAV (VOR) that are
the emergency radios (and, therefore, cannot be
turned ON or OFF) have an N/A annunciation in place
of ON or OFF. In some installations, the RMU can be
inhibited from calling up the RADIO ON--OFF page.
2. Single DME and ADF installations have their
respective ON--OFF functions removed from the No.
