and then turn it up or down relative to the rest of the background sounds (those normally not heard in
the pilot's headset).
The TACAN volume is normally used to get the morse code of the emitting station in the headset but
this is not implemented in BMS, so that volume control is not implemented. There is not even a need
to switch to knob out of OFF for the TACAN to work, it's coded always on. Likewise there is no ILS
audio but this time the knob can be turned ON and OFF to power the ILS system. Unlike BMS 4.32
where the ILS was always on the pilot now needs to power the ILS to be able to see ILS symbology.
Finally, the HOT MIC switch is not implemented.

setup, or with regular keystrokes.
The COMM1 mode knob has three-position: OFF, SQL and GD.
In OFF squelch mode is disabled (though squelch is not implemented in BMS).
In SQL the squelch mode is activated helping reduce background noise in normal operations.
In GD the main receiver and transmitter are tuned to the guard UHF frequency (243.000). Please note
GD position is not functional when the CNI is in BACKUP (guard is then selected from the backup
UHF panel).The push function is not implemented in BMS.
The COMM2 power and mode knobs have the same functions, but for the second radio (VHF).
GD position tunes to VHF guard (121.5).
The secure voice and TF knobs are not supported in BMS.
The MSL knob is used to set the sidewinder missile acquisition sound level. This control can be set
through an analogue potentiometer via the advanced setup or with regular keystrokes. The knob has
no ON/OFF position so at ramp and during your FENCE check you should check its position, unless
you use a potentiometer to interface it. In that case the volume is set at whatever position the pot was
left during the last flight.
The THREAT knob is used to set the TWS (Threat Warning System) sound level. This control can be
set either with an analogue potentiometer via the advanced setup or with regular keystrokes.
The knob has no ON/OFF position and at ramp and during your FENCE check you should check its
position unless you use a potentiometer to interface it. In that case the volume is set at whatever
position the pot was left during the last flight.

The AUDIO 2 panel provides control to the less frequently used
communications system. The intercom volume knob is used to control
the volume of all sounds normally heard in the pilot's helmet. It allows
the user to set the respective individual volumes to a desired 'mix' level
The AUDIO 1 panel controls the primary communication systems.
Unless otherwise specified, the controls are active regardless of the
position of the CNI switch on the AUX COMM panel.
The COMM1 power knob has an ON/OFF switch and when rotated past
the ON position increases volume for the COMM1 radio (UHF). This
control can be set through an analogue potentiometer via the advanced
