When using a headset, this control adjust
your own voice level heard in the
headphones. To adjust the level, tap the
Talk button once to turn on the headset
microphone. Then, use a small Phillips
head screwdriver to increase or decrease
your voice level while talking into the
microphone. (This control is accessible
by removing one (1) screw in the belt
clip.)
This connector accepts a 4-wire Bosch
boom microphone headset.
On the BP-2002, intercom channels are
connected via a pair of 6-pin connectors
(one male and one female). The male and
female connectors are wired together in
parallel, providing a loop-through at each
connector pin. Use one connector to
connect to the intercom channel. Use the
other connector to daisy chain a cable to
the next beltpack or other station on the
channel.
Local Power Input - Normally, the
BP-2002 is power from the intercom
system and turns on with the
intercom system. The BP-2002
beltpack may also be powered from
an optional power supply
(21-30 VDC) connected between
pin 2 (+) and pin 1 (-) of the intercom
channel connector.
On the BP-1002, the intercom channel is
connected via a pair of 3-pin connectors
(one male and one female). The male and
female connectors are wired together in
parallel, providing a loop through at each
connector pin. Use one connector to
connect to the intercom channel. Use the
other connector to daisy chain a cable to
the next beltpack or other station on the
channel.
