6 - DME SELECT BUTTON
− Allows selection of the DME Hold Mode, tuning a different DME
channel, not paired with the VOR/ILS frequency, without
changing the active VOR frequency. Repeated pressing of this
button enables display and selection of the DME channels in
VHF and TACAN formats, and then back to the paired
VOR/DME mode.
7 - CROSS-SIDE TRANSFER BUTTON
− With the cursor in any window, except the ATC, TCAS or HF
display, pressing this button will transfer the entire RMU
operation and display from the cross-side system.
− With the cursor in the ATC or TCAS window, pressing this
button selects which transponder will be in operation.
− With enhanced TCAS, the button allows control of TCAS data in
the cross-side display.
− With the cursor in the HF window, pressing this button toggles
the display between HF1 and HF2 tuning pages. There will be
dashes in the window if the HF in view is not the selected HF.
8 - TEST BUTTON
− When pressed, causes the component associated with the
present position of the yellow cursor box to activate its internal
self-test circuits for a complete end-to-end test of the function.
To properly accomplish the equipment self-test, the Test Button
must be pressed and held down as follows:
− About 2 seconds for COM transceiver self-test.
− From 5 to 7 seconds for DME, ATC and ADF self-test.
− About 20 seconds for NAV (VOR/ILS) self-test.

equipment to its normal operation in the actual function.

radios are automatically commanded back into normal operation.
