The following describes how to use and adjust the
SAFE controls. It also explains exactly how the SAFE
unit operates. This will allow you to easily set all unit
functions to your specific needs. If you are not familiar
with the SAFE operation, perform the next few steps
while the vehicle is not in motion.
Intercom operation and adjustment can be per-
formed by the following procedure:
1. Set the ON/OFF switch to the “ON” position and
turn both RECeive VOLume controls all the way
down (counter-clockwise).
2. Turn both intercom VOLume controls to the 10
o’clock position and both SQuelch controls all the
way up (clockwise). Notice the intercom is now
continually activated and you should be able to
talk between headsets.
3. To adjust the intercom SQuelch controls for voice
activated operation (VOX), it is helpful to have
some background noise present. It may also be
necessary to turn up the intercom VOLume con-
trols. Turn both intercom SQuelch controls all the
way counter-clockwise. Now, without speaking,
rotate one of the SQuelch controls clockwise until
you hear the background noise in your headset.
Next, using that same SQuelch control, rotate
counter-clockwise small, incremental amounts
until the background noise disappears. (This pro-
cedure is necessary because the squelch is a “fast
on, slow off” system). That SQuelch control is now
set.
4. Adjust the other intercom SQuelch control similarly
by turning it clockwise until you hear background
noise. Rotate counter-clockwise incremental
amounts until the background noise disappears.
Small adjustments may be necessary if background
noise changes significantly - such as from idle to full
power.

instructions to the users of the safe system.
