INSTALLATION
IC-1 and IC-11LS
Permanent installation may be accomplished by
removing the belt clip and utilizing the threaded
belt clip mounting holes along with the additional
threaded hole in the case to secure the unit to
other equipment. These holes accept No. 6-32
machine screws. Screws may extend 3/16-inch
into unit. These units may also be rack mounted
using an RM-13 Rack Mounting Kit.
IC-1 F and IC-1 FILS
After running wires to the electrical box where
the unit will be located, refer to the label on the
rear cover of the unit and make connections as
indicated. It is not necessary to observe polarity
when connecting intercom line wires. Connect
the power supply dc return wire to the SHLD
terminal. If another set of wires is to be run from
this unit to another intercom station, connect
these wires at this time.
OPERATION
Headset Jack: Accepts headsets with dynamic
microphone and dynamic headphone(s).
Headphone VOLUME Control: Adjusts
headphone listen level. Does not affect mic level.
MICION Switch (IC-1, IC-IF): In the MIC
position, the microphone is shut off but the
intercom line is still monitored by the phones. In
the ON position, the microphone is operational
for two-way communication.
OFFIMICICALL Switch (IC-IILS, IC-1 FILS): In
the OFF position, the microphone is shut off but
the intercom line is still monitored by the phones.
In the MIC position, the microphone is
operational for two-way communication. In the
CALL position, with the switch held continuously,
an inaudible signal is sent to all other stations on
the line: on those stations with light signalling,
the Call Indicator lights will illuminate. When
another station responds verbally, release the
switch and it will automatically return to the MIC
position for two-way communication.
Call Indicator LED (IC-1/LS, IC-1FILS):
Illuminates when station is being called. Does not
illuminate when sending a call signal.
