DESIGN
The V-9962 is designed to eliminate paging system
acoustic feedback with an option to prevent DTMF
tones from being broadcast through the paging system.
When a page is made, the message is digitized and
saved. Upon completion of the live page, the message
is released to play over the system speakers. This
eliminates the offensive squeal of feedback commonly
produced by telephones or microphones when making a
page.
