System Adjustments
The factory settings are suffi cient for most installations. The system can
be adjusted to customize the installation.
Speaker Volume Adjustment
If the resident’s voice from the speaker is too loud or not loud enough, the
speaker’s volume can be adjusted.
1. Locate the SPEAKER VOLUME adjustment on the CPU circuit
board.
2. Make a directory number call to test the speaker volume. While
listening to the resident’s voice, turn the adjustment clockwise for
more volume, counterclockwise for less volume.
Display Contrast Adjustment
If the lighting in the area or the viewing angle of the display in the
installation causes the display to look too dark or too light, the display’s
contrast can be adjusted.
1. Locate the DISPLAY CONTRAST adjustment on the CPU circuit
board.
2. Turn the adjustment clockwise and counterclockwise until display
has the best visibility.
System Tone Adjustment
The sound level of the tones that the system produces can be adjusted.
1. Locate the TONE VOLUME adjustment on the CPU circuit board.
2. Press keys on the keypad while adjusting the TONE VOLUME until
the tones are at the desired level. Turn the adjustment clockwise
for more volume, counterclockwise for less volume.
System Restart Button
Pressing the SYSTEM RESTART button will reboot the system’s
microcontroller. NO SYSTEM INFORMATION WILL BE ERASED.
System Diagnostics
Several components on the main circuit board are for monitoring the
system during operation. When calling for technical assistance, Linear’s
Technical Services Department may ask the installer to use these
components to diagnose the system.
