Operation
GAI-Tronics offers two types of Page/Party
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. Speak directly into the handset to make the page announcement. The paged
individual lifts the handset of a Page/Party
•
Page/Multi-Party: Select an available party line using the five-position selector switch. Then make
the page announcement, 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
Auxiliary Headset Operation
The auxiliary headset allows the user to make page announcements and conduct party-line conversations
hands-free from up to 30 feet away from the station, while providing noise reduction for hearing
protection. When an auxiliary headset/cable assembly is plugged into the auxiliary jack, a party-line
connection is automatically established (the same as lifting the handset.).
The auxiliary headset has priority over the handset. When the user lifts the handset from the cradle while
the auxiliary headset is in use, the handset's microphone and page switch are disabled, but the handset
receiver remains active. A GAI-Tronics 10416 series headset/microphone assembly is required.
