Intercom Operation
In conjunction with the model 4640 intercom system,
the touchpad can be used as an intercom providing two-
way or listen-only communications.
Two-Way Communication
To turn on one intercom only, press the number of the
touchpad you wish to call (1-8), then press ICOM . To
turn off the intercom, press ICOM again.
To turn on all intercoms (or page), press ICOM . To
turn off all intercoms, press ICOM again.
Listen-Only Communication
To listen to one intercom only, press the number of the
touchpad you wish to call twice, then press
ICOM . To stop listening to a touchpad, press ICOM
again.
EXAMPLE:
To listen to touchpad 7, press:
7 7 ICOM .
To listen to all intercoms, press 1 0 ICOM . To stop
listening, press ICOM again.
Do Not Disturb Feature
If you want to block all communication from an
intercom station, press 9 ICOM . Anyone attempting
to call the station will hear a busy tone. Press ICOM
again to reinstate communication.
Intercom Timeout
The programmed intercom timeout function allows you
to automatically limit use of the touchpad intercom from
between 15 - 255 seconds. The intercom will hang up
automatically after the programmed amount of time has
elapsed. It emits a warning beep 10 seconds before it
turns off.
Timeout does not automatically occur when you are
listening to only one station. This allows you to monitor
an area continuously.
