3. Turn the user adjustment control fully counterclockwise.
4. Listen for a single beep from the speaker indicating the speaker amplifier is in the minimum level
adjustment mode.
If the page line is in use immediately after the beep tone is heard: use the page signal as the reference
to adjust the speaker volume level.
If the page line is inactive following the beep tone: a continuous tone is activated to make the
minimum level adjustment. All page line activity is ignored until completion of the adjustment once
the tone is activated. Use the test tone as a reference to adjust the speaker amplifier output level to
the desired volume.
3. Turn the adjustment potentiometer clockwise for the desired output.
The test tone automatically shuts off 5 seconds after the last adjustment.
Offset Level Adjustment
The offset level allows the output of the SmartVolume™ speaker amplifier to maintain a set difference or
offset between the ambient noise level and the speaker output level.
1. Loosen the two screws on the GAI-Tronics nameplate and rotate it counterclockwise.
2. Insert a 1/8-inch flat blade screwdriver through the access hole and into the potentiometer.
3. Turn the user adjustment control fully clockwise.
4. Listen for two beep tones indicating that the station is in offset adjustment mode.
If the page line is in use immediately after the beep tone is heard: use the page signal as the reference
to adjust the speaker volume level.
If the page line is inactive following the beep tone: a continuous tone is activated to make the
minimum level adjustment. All page line activity is ignored until completion of the adjustment once
the tone is activated. Use the test tone as a reference to adjust the speaker amplifier offset level to the
desired volume.
5. Turn the adjustment potentiometer counterclockwise to the desired output level.
The test tone automatically shuts off 5 seconds after the last adjustment.
VLC (Volume Level Control) Adjustment (ADVANCE Systems only)
VLC overrides the normal volume control setting. This allows changing the amplifier level to a preset
level during an emergency page. The factory default setting for the VLC level is 10% of maximum
power (nominally 1.2 watts).

OTE
: The system must be equipped with a SmartSeries MCU (Master Control Unit) to activate the
VLC function.
1. Force the station into the VLC mode by executing a page from a station programmed by the MCU to
activate the VLC function.
2. Turn the user adjustment control fully counterclockwise during the page.
3. Listen for two beep tones through the page speaker indicating VLC adjustment mode is active.
4. Turn the user adjustment control to the desired speaker level using the live paging signal to adjust the
level.
The station automatically exits the VLC adjustment mode and reverts to normal operation 5 seconds
after the last potentiometer adjustment.
