Note
The AirCell
®
ST 3100 Transceiver incoming audio adjustment allows Handset A, B and C to be
independently adjusted using the 14-turn potentiometer. The factory sets the 14-turn potentiometers to a
mid-range setting and in most installations will not need adjustment in the field. These adjustments are
minor volume adjustments that don’t adjust from a minimum to a maximum volume level. The Audio
Panel side tone level and volume trim level are also adjustable. These adjustments change the audio
level out of the Audio Panel (A/P). The AirCell
®
ST 3100 Transceiver also provides a microphone bias
level through the Audio Panel. This is an ON/OFF Bias logic function enabled by a jumper.
