Speak directly into the handset to make the page announcement. The paged ® individual lifts the handset of a Page/Party station for two-way communication over the party line. • Page/Multi-Party: First, select an available party line using the five-position selector switch. Then make the page announcement as in single-party operation, remembering to indicate which party line is being 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 chassis of the amplifier using a small standard screwdriver. However, these levels have been factory-set for optimal performance. Do not adjust these levels unless you have followed all the steps in the Troubleshooting section and are still not satisfied with the station performance. Each adjustment is clearly labeled: • Microphone Gain: adjusts the gain level from the microphone signal to the page or party lines • Receiver Sidetone: the amount of signal transmitted from the microphone to the receiver of a handset • Receiver Volume: adjusts the gain level from a party line to the receiver • Speaker Amplifier Gain: adjusts the speaker volume; also accessible from the front panel Sold by: http://www.TWAcomm.com Toll Free: (877) 892-2666 \\s_eng\gtcproddocs\standard ioms - current release\42004 instr. manuals\42004-317a.doc 10/03 Pub. 42004-317A Model 701-302, 701-304, and 701-307 Handset/Speaker Amplifiers Page: 4 of 7 Maintenance The following table lists some hints to aid technicians in troubleshooting: Troubleshooting Problem Solution Any problem with station Review all the steps of the installation, ensuring that you have correctly performance occurs. followed ALL steps.
