Transceiver Switches
These are five 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, PA.)
(2)
Receiver Switches
These are three 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 (three above and three below the
switches) are interchangeable to allow
customization. (Default – NAV1, NAV2, ADF1,
ADF2, MKR, DME.)

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.
