Testing and Adjustment Procedure
To test that the classroom audio is muted when a
PA system announcement (a page) occurs:
1. Turn the classroom audio on.
2. Speak into the PA system microphone. The
classroom audio should be muted while the PA
page occurs and be restored when the page
ends.
3. If the program fails to mute the classroom audio
during a page, turn the Sensitivity adjustment, on
the front panel of the PVS 405D, clockwise.
4. If the classroom audio is muted without a page
occurring, turn the Sensitivity adjustment
counterclockwise.
