NOTE: Any radio equipment that is not powered up when the test is
initiated by the RMU will generate an error message.
Additionally, the pilot may perform a test by pressing the Test Button
on the RMU Bezel Panel, which causes the activation of the self-test of
the component associated with the window in which the yellow cursor
is located. Upon successful completion of this test, a PASS message
will be displayed for a short time in the window, indicating the
successful completion of the test. If this test is not successfully
completed, an error message (ERR) will be displayed in the window.
NOTE: Errors detected by the self-test indicate one or more parameter
outside their self-test limit, but may not necessarily indicate
non-operation of the function. The pilot should verify the
operation of the function.
CROSS-SIDE OPERATION
The RMU is provided with a feature called cross-side operating mode.
This feature allows the RMU to be changed from its normal operating
mode of tuning the on-side radio equipment to the mode of tuning the
opposite side radio equipment.
The cross-side operation is selected by pressing the cross-side
Transfer Button, labeled 1/2, on the RMU Bezel Panel, with the yellow
cursor box in any window, except the ATC/TCAS window. The entire
RMU display and operation is transferred from the opposite side to the
side that has commanded the Cross-side Operating Mode. If the yellow
cursor box is in the ATC/TCAS window, pressing the cross-side
Transfer Button selects which transponder (1 or 2) will be in operation.
In the cross-side operation, the RMU Window/Control Side Ident will be
displayed in magenta on the side that has selected the operation and
any change made will be displayed in yellow on the opposite side RMU
to indicate that the change was carried out remotely.
