10. INTERCOM MODE SELECT SWITCH -- Has three modes
"ALL", "CREW", AND "PILOT" which are selected with the
toggle switch on the lower left side on the faceplate. In the
"ALL" position the pilot, copilot, and passengers are all on the
same intercom "loop" and everyone hears the radios. In the
"CREW" position the pilot and copilot are on one intercom
loop and can hear the radios while the passengers have their
own dedicated intercom and do not hear the radios. In the
"PILOT" mode the pilot hears the radios but is isolated from
the intercom while the copilot and passengers are on the
same intercom loop and do not hear the radios.
When either the "ALL" or "CREW" intercom modes are
selected, the pilot's and copilot's intercom volume is controlled
by rotating the Crew Intercom Volume Knob (left inner knob)
while the passenger's volume is controlled by rotating the
Passenger Intercom Volume Knob (left outer knob). When the
"PILOT" intercom mode is selected, the copilot's and
passenger's volume is controlled with the Passenger Intercom
Volume Knob. Remember, the volume knobs on the KMA 26
control intercom volume only, not the receiver's volume.
11. MARKER MUTE BUTTON -- Mutes currently active marker
beacon audio.
