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:
To call a master station:
1. Simply press the CALL button, which rings an electronic tone (for as long as button is held). The corresponding LED will

2. When master replies, speak handsfree.
3. LE-A3 and LE-AN3 can selectively call to up to 3 LEF master stations.
When called by a sub station while talking to another station:
The station's LED will light for 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 disconnect from
original call, the depress the selector button with lit LED to answer the next call.

Make sure jumper is installed between E and – 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 directory cover.
(Remove cover and use small screwdriver to adjust.)
