Installation of the Model 713-102 Speaker Amplifier Operation GAI-Tronics offers two types of Page/Party® systems: Single-Party (with one party line) and Multi-Party (with five party lines allowing up to five simultaneous two-way conversations). • Single-Party: To initiate a call, lift the station handset and press the page button or pressbar. Speak directly into the handset to make your page announcement. The paged individual lifts the handset of any Page/Party® station for two-way communication over the party line. • Multi-Party: First select an available party line with the party-line selector switch. Make your page announcement as in single-party operation, remembering to indicate the party line used. The paged individual then selects the indicated party line and lifts the handset for two-way communication. The following adjustments are accessible through the rear amplifier chassis using a small screwdriver: • Microphone Gain: adjusts the gain level from the microphone signal to the page or party lines • Receiver Sidetone: adjusts the amount of signal transmitted from the microphone to the handset receiver. To adjust the receiver sidetone, blow into the transmitter while turning the sidetone adjustment. The sidetone is properly set when the person blowing can barely hear themselves. • Receiver Volume: adjusts the gain level from a party line to the receiver \\s_eng\gtcproddocs\standard ioms - current release\42004 instr. manuals\42004-175a.doc 07/04 Pub. 42004-175A Page: 3 of 4 Model 713-102 24 V DC Remote Speaker Amplifier Troubleshooting The following table lists some of the most common difficulties encountered in Page/Party® systems. Included are some troubleshooting hints to aid in remedying these problems. Problem Solution Any problem with station performance occurs. Review all the steps of the installation, ensuring that you have correctly followed ALL steps. Check all the terminations on the board and in the line balance assembly before proceeding to any other adjustments. Integral speaker level requires adjustment. 1. Adjust the volume control behind the nameplate on the front panel. Outgoing conversation level requires adjustment. 1. Adjust the microphone gain by removing the amplifier and attaching a Model 10440 Series Extension Maintenance Cable between the connectors. Use a small standard screwdriver (1/8-inch blade) to slowly turn potentiometer (R17) on the rear chassis of amplifier until reaching the proper microphone gain. Remove the cable and reinstall the amplifier. 2. Replace the handset microphone. Incoming conversation level requires adjustment. 1. Use a small standard screwdriver to adjust the receiver volume control on the rear of the amplifier using the extension cable assembly as described above. 2. Replace the speaker or driver. 2. Replace the receiver element in the handset. Feedback/distortion (a hum or buzz on the line) occurs during all Page/Party® station operation. 1. Adjust the receiver sidetone on the rear of the amplifier using the extension cable as described above. 2. The line may be improperly terminated. Inspect the system cable for loose connections, shorts, and grounds. Line balance assembly connections are critical. 3. Replace the line balance assembly. Feedback occurs only during page. Use the muting feature in the amplifier enclosure at the terminal blocks. Connect the violet wire at terminal 8 to terminal 7. Sidetone (how the operator hears his own voice) requires adjustment. 1. Adjust the receiver sidetone at the amplifier, using the extension cable as described above. 2. Check that the line balance assembly resistors are connected properly. (See GAI-Tronics Publication 42004-139 or 42004-140 for 24 V dc systems.) Crosstalk occurs. 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. \\s_eng\gtcproddocs\standard ioms - current release\42004 instr. manuals\42004-175a.doc 07/04 Pub. 42004-175A Page: 4 of 4 Model 713-102 24 V DC Remote Speaker Amplifier Specifications Power input voltage............ ............................................................ 21-28.8 V dc range, 25 V dc nominal Construction/Finish .............................................................. 16-gauge cold-rolled steel/gray polyurethane Speaker Amplifier ..............
