but has the internal capability to be preset to a low minimum value, if desired.

ICS audio is normally muted during TX operations, but may be adjusted internally for a user specified

muting depth, or the muting function may be disabled by jumper selection.

The Receive or RX

control is the larger,

outer, bottom knob,

and is color coded

to the individual RX

level controls.

The Intercom or

ICS control is the

smaller, inner, top

knob, and is color

coded to the VOX

2.1.3 RX or RECEIVE VOLUME CONTROL

The RX LEVEL knob controls the volume level of all the system receivers. Fully clockwise is the

maximum volume level, and counter-clockwise the minimum. RX audio is derived from both the

receivers (such as Nav aids) and the transceivers (Comms, etc.) in the system. The RX audio level

cannot be set to zero, and has an internal minimum level setting.

RX audio is normally partially muted during TX operations, and is adjustable internally to the desired

level for TX sidetone. Note that sidetone must come from the radio itself.
