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. Turn the User Adjustment
Control fully clockwise and listen for the two beep tones indicating that the station is in the Offset
Adjustment mode. A continuous tone should be heard from the station speaker. Turn the adjustment pot
counterclockwise to the desired output level.
N
: If the page line is in use immediately after the two beep tones are heard, the page signal should be
OTE
used to make the offset level adjustment. If the page line is inactive immediately following the beep
tones, a continuous tone is activated to make the minimum level adjustment. After the tone is activated,
all page line activity is ignored until completion of the adjustments.
VLC Level Adjustment
When activated, the VLC overrides the normal volume control setting allowing the amplifier level to
change 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).
N
: The system must be equipped with a SmartSeries Master Control Unit (MCU) to activate the
OTE
VLC function.
To adjust the VLC Level:
1. Force the station into the VLC mode by having someone execute a page from a station programmed
by the MCU to activate the VLC function.
2. During the page, turn the User Adjustment Control fully counterclockwise, and listen for two beep
tones through the page speaker indicating the VLC Adjustment mode has been activated.
3. After the two beep tones, 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 pot adjustment.
