BP-319-351 OPERATION
PROGRAMMING
The BP-319/351 uses four modes of
operation to control the Mic Kill and
Audible Call Alert features (see table 1,
page 8).
Mic Kill:
When this feature is enabled and a Mic Kill
signal is received from the intercom
channel, the BP-319/351 microphone will
be turned off the Mic Kill signal will have
no affect on microphones attached to the
BP-319/351.
Audible Call Alert
When this feature is enabled, an audible
beep is heard in the headset whenever
there is an incoming call from the same
intercom channel.
When this feature is diabled, no audible
beep is heard for incoming calls.
INTERNAL SWITCHES, JUMPERS,
AND ADJUSTMENTS
There are several internal switches,
jumpers and adjustments that affect
operation. These are described below. To
gain access to the switches, jumpers, and
adjustments, disconnect all power and line
connections. Remove two screws from the
top of each side of the case and two
screws from the bottom of each side of the
case. The jumper and switch locations are
shown in Figure 2.
Sidetone Adjustment
The side tone adjustment is accessible
either internally (see Figure 2) or by
removing the belt clip mounting screw
shown in Figure 1.
