Transceiver Switches
These are six white two-position toggle
switches. When a switch is set to the ‘up’
position, audio from the associated
transceiver is routed to the phones.
The legends (above the switches) are
interchangeable to allow customization.
(Default – COM1, COM2, AUX, FM1,
FM2, FM3.)
(2)
Receiver Switches
These are two blue three-position centre-off
toggle switches. When a switch is set to the
‘up’ or ‘down’ position audio from the selected
receiver is routed to the phones.
The legends (two above and two below the switches) are
interchangeable to allow customization. (Default – NAV1, NAV2,
and ADF1, M/D.)
Note
: When M/D is selected, both MKR and DME
audio will be routed to the phones.
(3)
Receive Volume Control
This is a rotary knob that adjusts the phones volume
of the receive audio from minimum (CCW) to
maximum (CW). Individual radio volume controls
should be set to a nominal level, and then adjusted for
changing flight conditions using this control.
(4)
Mode Switch
This is a red two-position locking toggle switch. When set to the ‘up’
position, the unit is Emergency mode, and when set to the ‘down’
position, the unit is in Normal mode. The legends are interchangeable
to allow customization. (Default – EMER, NORM.)
The switch is lockable to prevent accidental changing of the mode. The
switch must be lifted to release the lock.
For full information on Emergency and Normal Mode operation, see
