Clear-Com BS850 (Last time buy) - Manual (Page 22)

Beltpac Receiver Frequency:
Select the desired Beltpac and the receiver
frequency for that Beltpac’s operation (P1-4, S1-4,
T1-4 or U1-16. If U1-16 is selected, use the
control knob and the up and down arrow buttons to
select the desired frequency, in 25kHz increments.
NOTE: When only one receiver is present, it will
switch between the two frequencies as needed.
When two receivers are present, the primary
receiver is Rx1 and the second receiver is Rx2.
Normally, Rx1 is for intercom Ch1. Rx2 is for
intercom Ch2, unless base station Tx2 is off or in
IFB mode. In that case, both intercom channels go
through base Tx1 and thus Beltpac Rx1. Normally,
Beltpac Rx1 is the same as base station Tx1, and
Beltpac Rx2 is the same as base station Tx2.
Beltpac Receiver Squelch Level:
Select the Beltpac and receiver, then use the
control knob to adjust its squelch level.
NOTE: Rx2 Squelch adjustment is reserved for a
second receiver, when a Beltpac has two receivers.
BPCN is the Beltpac that is plugged into the base
station, therefore adjustments to its squelch level
are effective immediately.
Beltpac Buttons A and B Setup:
Select the Beltpac and the Mode (Off, Momentary
or Lock) for Buttons A and B on each Beltpac.
