Volume: This is a master intercom volume control to all
headsets on the system. Adjust it to match the radio
volume adjusted above.
Squelch: This control is adjusted from the Driver or Of-
ficer position, while wearing a Radio Transmit Headset.
Adjust it with the apparatus engine running, so that "nor-
mal" background noise is present. Start with this control
fully clockwise; then slowly rotate counterclockwise until
the background noise is no longer heard. Do not set this
control any further than necessary. Once set correctly,
additional adjustment should not be required.
These controls do not affect the radio
squelch control setting.

The Intercom 3000A radio transmit level has been pre-
set to a nominal level at the factory. In most installations,
satisfactory performance is obtained without having to
re-adjust this level. However, if it is necessary, optimal
RF carrier modulation level may be set by adjusting the
"Transmit Level Adjustment" potentiometer. This control
is located on the interface circuit board of the System
3000A Intercom and can be accessed by removing the
top metal case of the System 3000A Intercom. See in-
terface Circuit Board layout below.
This adjustment should be performed by a qualified ra-
dio technician with access to a suitable RF communica-
tions test set.
