RINGER VOLUME adjusts the level of the night ringer tone output. The MUSIC
LEVEL volume control should rst be set to the customer’s satisfaction. When
adjusting this level, the CLIP LEVEL indicator should be observed to ensure that
the amplier signal is not distorted.
MUSIC MUTE LEVEL adjusts the level of the background music heard during a
paging announcement. The fully counterclockwise position provides maximum
muting (no background music). The background music mute level should be
set to the customer’s satisfaction, but the page announcement should be heard
distinctly above the background music.
MUSIC LEVEL adjusts the level of the background music output. The back-
ground music level should be set to an acceptable level without overdriving the
system. When adjusting this level, the CLIP LEVEL indicator should be observed
to ensure that the amplier signal is not distorted.
MIC LEVEL adjusts the level of the microphone page output.
CAUTION: To prevent feedback the microphone should not be placed near any
paging loudspeakers.
TEL VOLUME adjusts the level of the telephone page output. When adjusting
this level, the CLIP LEVEL indicator should be observed to ensure that the ampli-
er signal is not distorted.
The Automatic Level Control (ALC) VOLUME controls the level at which the am-
plier will begin to limit the output signal.
Adjustment Procedure
1. Disable ALC by turning ALC VOLUME to the maximum counterclockwise
position.
2. Make a page, speaking softly, yet distinctly. Set the TEL VOLUME control to
the desired paging level during this page.
3. Make another page, speaking relatively loudly this time. Rotate the ALC
control clockwise while making the page, until it has the same loudness as
the rst page.
NOTE: The TEL Volume and the ALC controls work together to set the output
level.
NOTE: The CLIP indicator should not show excessive clipping during loud pages.
If this is occurring, the ALC VOLUME must be adjusted until clipping is at a nom-
inal level.
