INTRODUCTION

The V -9970 is a Single Zone One-way Station Level
Page Control designed to provide ring trip and page
access circuitry for use on standard telephone lines
(PABX, Centrex or C. O. line connections). These
instructions contain the specifications and
information necessary to install, operate and maintain
the Single Zone One-way Station Level Page Control.

Regulatory Information

This equipment has been tested and found to comply
with the limits for a Class A digital device pursuant to
Part 15 of FCC Rules. These limits are designed to
provide reasonable protection against harmful
interference when this equipment is operated in a
commercial environment. This equipment generates,
uses and can radiate radio frequency energy and if
not installed and used in accordance with the
instruction manual, may cause harmful interference to
radio communications. Operation of this equipment in
a residential area is likely to cause harmful
interference in which case the user will be required to
correct the interference at his/her own expense.

4. Attach two wires from a music source output

DESIGN

The Valcom V -9970 is designed to provide paging
access from a standard analog PABX station number,
a C. O. line or analog Centrex line. The Page Control
incorporates the latest technology Digital Signal
Processor (DSP) to recognize and transfer speech
only, thus eliminating unwanted noises such as pops
and tones. A discriminating Automatic Gain Control
(AGC) is provided to make quiet pages louder and
loud pages quieter.

The Single Zone One-way Station Level Page Control
provides a music input with volume control for
background music and an additional 1 Amp internal
relay output (This input closes during a page to
provide user page notification if desired).
