User manual TELEX AUDIOCOM IC-1 REV J

[. . . ] Power Requirements: Voltage: 24 Vdc nominal. Current: No signal - 8 milliamps (IC-1, IC-IF), 12 milliamps (IC-1/LS, IC-1F/LS). Average talk - 12 milliamps (IC-1, IC-IF), 20 milliamps (IC-1/LS, IC-1 F/LS). [. . . ] In the ON position, the microphone is operational for two-way communication. OFFIMICICALL Switch (IC-IILS, IC-1FILS): 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.
