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, the lift the station handset and press the page button or the
handset pressbar. Speak directly into the handset, make your 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 with the five-position selector switch. Then make your page announcement as in single-party operation, remembering to indicate the party line 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
