OPERATOR’S MANUAL
CMA-9000 FLIGHT MANAGEMENT SYSTEM
VHF1 [1L]: Display and modify active/standby preset number and channel of the VHF1 radio. Selecting LSK 1L
when the scratchpad is empty will toggle the standby and the active preset/frequency.
VHF2 [1R]: Same as above, but referencing VHF2 instead of VHF1 and LSK 2R instead of LSK 1L.
NOTE: It is possible to have "-" in one or both of the active and standby fields after FMS maintenance. Toggling
is not allowed when "-" are present in the standby field. Then, a frequency needs to be entered in the
standby field first before the active/standby field toggling is allowed, otherwise a warning message will
be displayed in the scratchpad.
