Adjustments

The inside front cover of the TI984 contains 3 potentiometers to adjust audio levels. Use a small standard screwdriver to adjust the page line level. Before adjustments are made, turn the Party Line Level potentiometer fully counterclockwise and the Page Line Level potentiometer approximately one-half of its travel. Use an outside telephone to establish communications through the TI984 with the GAI-Tronics paging system. Once the incoming call is connected to the page line, adjust the Page Line Level potentiometer until the volume level of the incoming page is approximately equal to a page made within the system.

After the page level is adjusted, pick up the incoming call at a station near the TI984. When communications are established, adjust the Sidetone Adjust potentiometer on the TI984 for minimum sidetone on the GAI-Tronics station. Sidetone is the amount of signal transmitted from the microphone to the receiver. To complete this adjustment, blow into the microphone at the station while adjusting the potentiometer on the TI984 for minimum signal in the ear piece of the station. As the potentiometer is adjusted, the signal will decrease (null), then increase.

After the sidetone adjustment is completed, adjust the Party Line Level potentiometer until the level of the signal from the telephone line is comparable to the level of a signal within the system.

If all adjustments are made properly, pages from the TI984 will be the same volume as pages from a Page/Party® station. Party line adjustment should be tested from a Page/Party® station. When properly set, this communication with an outside call will sound like communication with another station.
