System Adjustments
The factory settings are suffi cient for most installations. The system can
be adjusted to customize the installation.
Digital Speech Volume Adjustment
The sound level of the tones and digital voice that the system produces
can be adjusted.

adjustment on the main circuit board.
2. Press the key test the digital speech level. Turn the

Speakerphone Volume Adjustment
If the resident’s voice from the speaker is too loud or not loud enough, the
speaker’s volume can be adjusted.
✦ NOTE: Adjusting the SPEAKERPHONE VOLUME too high will
prevent proper operation. This control only affects the speaker
volume, not the volume from the microphone.

listening to the resident’s voice, turn the adjustment clockwise

on the main circuit board.
2. Turn the adjustment clockwise and counterclockwise
until display has the best visibility.
