BG-10C All Call, Chime, and Music Adaptor:
Music is selectively distributed to all LEF station speakers, controlled by switch settings in BG-10C.
When any station initiates a call, the music mutes automatically.
When door station calls in, chime tone is transmitted to selected inside stations, controlled by switch settings.
Privacy (PRIV) feature:
When PRIV button is depressed, the calling master can call into a station in "privacy" mode, but the "listen" mode is cut off.
To release from PRIV, press TALK momentarily.
LE sub stations:

2. When master replies, speak handsfree.
When called by a sub station while talking to another station:
The station's call-in LED will light for approx. 20 sec., but call tone is muted. (NOTE: If A/B switch is set to "B" position, the
call tone will be heard at a muted level, even if the receiving station has another station selected.) Depress OFF button to

Make sure jumper is installed between E & – at the subs and the master
station.
Same as above; E & – jumper must be in place. If 3 wires are used, 1 &
– are for call-in, and 1 & E are for communication. Check continuity and
connection of wires.
The C terminal of the master means "CALL", and allows master-to-master
communication. Make sure the C terminal of each master is connected to
a designated # terminal on all other masters. (example: C at master 1
connects to the 1 terminal of all other masters.)
Adjust call tone volume with slide switch located under operation plate.
(Remove plate and use small screwdriver to adjust.)
