DESCRIPTION

The Model HCM-9 is a versatile control station
for the Bogen Deluxe Home Communications System.
The Model HCM-9 may be used with any combination
of control or remote stations totalling a maximum of
nine.

Each deluxe communications system requires one
Model HCA-l Amplifier. The output of a radio receiver

may be applied to an input jack on the amplifier and
distributed to Model HCM-9 Control Stations - but not
to remote stations. Such signal distribution does not
interfere with normal operation of the intercom as
calls will override the program. For further information,
consult the instruction manual provided with the Model
RCA-1 Amplifier.

OPERATION

Always bear in mind that only one station may
talk at one time in this system.

Leave the function switch in the STAND BY
NORMAL position, unless monitoring another con
trol station.

Always adjust the VOLUME when receiving,
never when talking.

Identify your station when originating a call.

IMPORTANT POINTS TO REMEMBER

INSTRUCTION

A control station must have its MONITOR
switch in the ON position in order to monitor an-
other control station.

In order for a control station to be monitored
by another control station, the monitored station
must have its function switch in the NON PRIV
position.

The control station has 8 selector slide switches,
each with an ON and OFF position for selection of
specific stations.

The MONITOR slide switch, located on the ex-
treme left, is used to monitor other control stations.
When the MONITOR switch is in the ON position and

the functiOn switch is in LISTEN position, the control
station can monitor any other control station that has
its function switch in NON-PRIVATE position.

Operating instructiOns are arranged by function
as determined by the position of the function selector

switch. It is essential to follow these instructions
carefully.

1. STAND BY NORMAL: With the function switch in
the STAND BY NORMAL position, the control station
may be called by another control station. This should
be the normal position when the control station is
not in active use. In this position the control station
will not be disturbed by other communications and
will still be able to receive a directed call.

2. TALK: Select desired control station or remote with
selector switch. Depress function selector lever to
TALK position and call the desired station, identify-
ing your station at the same time. Release the lever
to LISTEN position and listen for acknowledgement
of call. When acknowledgement is received, again
depress the lever to TALK and resume talking.

3. LISTEN: Upon hearing a call and the identity of
the calling station, depress the function lever to
TALK, then acknowledge the call. Release the lever
to LISTEN position and listen.

NOTE
Do not have two control stations in simultaneous
communication with the same remote station.
Under such conditions, it one control station is
in the TALK position While another is in the
LISTEN position, a loud squeal will be heard

at the listening control station and at the remote
station.

4. NON-PRIVATE: With the function selector in the
NON-PRIV position, a control station may be monitored
from any other control station which has its function
switch in the LISTEN position and the MONITOR
switch ON. When a control station has its function
switch in any position other than NON PRIV, the sta-
tion has complete privacy against eavesdropping.

5. MUSIC: The MUSIC positiOn allows the control sta-
tion to receive program material. The system con-
tinues to operate normally, and a call from another
control station will override the program.

CAUTION
The above instructions are {or properly in-
stalled music sources. Insufficient music audio
power can cause low volume, while excessive
power can damage components in the system.
Consult the instruction manual provided with
the Model HCA-l {or further information.

6. VOLUME: The control station has 3 VOLUME
control for setting the sound level. Always adjust
this control when receiving, never when talking. When
a control station is being monitored, make certain to
leave its VOLUME control at a high enough level to
permit calls to be made to the monitored station.
