Operation GAI-Tronics offers two types of Page/Party® systems: page/single-party (with one party line), and page/multi-party (with five party lines allowing up to five simultaneous two-way conversations). · Page/Single-Party: To initiate a call, lift the station handset and press the page button or press the handset pressbar. [. . . ] Use a small standard screwdriver to adjust the receiver volume control on the rear of the amplifier using the extension ribbon cable assembly as described above. Replace the receiver element in the handset. Use the muting feature in the amplifier enclosure at the terminal blocks. Connect the violet wire at terminal 8 to terminal 7. Adjust the receiver sidetone on the rear of the amplifier using the ribbon cable assembly as described above. Inspect the system cable for loose connections, shorts, and grounds. Line balance assembly connections are critical. Adjust the receiver sidetone at the amplifier, using the extension ribbon cable as described above. Check that the line balance assembly resistors are connected properly. One or more system cable pairs may be improperly terminated. Visually inspect the system cable connections for accidental crossing of the cable pairs or grounds. Incoming conversation level requires adjustment. Feedback occurs only during page. Feedback/distortion (a hum or buzz on the line) occurs during all Page/Party® station operation. Sidetone (how the operator hears his own voice) requires adjustment. Crosstalk occurs. f:\standard ioms - current release\42004 instr. manuals\42004-423b. doc 10/10 701-309 Handset/Speaker Amplifier (24 V DC) with Auxiliary Jack Pub. 42004-423B Page: 4 of 5 Specifications Amplifier Power requirements (24 V dc) Voltage. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 21­28. 8 V dc range, 25 V dc nominal Power consumed: zero/max. signal (12 watts) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2. 75W/27 W Construction/Finish. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 16-gauge cold-rolled steel/gray baked enamel Handset Microphone. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
