The DVA-1002 uses solid state memory and is virtually maintenance free. There are
no moving parts, tapes to replace or tape heads to clean.
The DVA-1002 will increase call handling capacity by answering calls on demand or
during the first ring, automatically adjusting the announcement length to ensure fast
call processing and provide instant rewind for the next announcement.

The DVA-1002 is equipped with a rechargeable NiCad battery that will maintain the memory for up to 2 hours during a
power failure. The DVA-1002 must be powered for 48 hours to fully charge the battery.
Installation
A. Standard Ring Trip 2 Wire
Use J2 only. Set protocol switch to “A.” Any ringing C.O. line or analog PABX/KSU station will be answered, given
a message, released and immediately be available for the next ring.

Wire the DVA-1002 with either or both the 4 wire E&M jack and/or the 2 wire ring trip jack as shown above. When using
the 4 wire E&M, the ring trip interface may be used for remote programming. The E&M functions will resume when
programming is finished.
Note: The DVA-500A requires a 24 hour unswitched 115V AC outlet. To protect the internal electronics, the
installation of a surge protector is recommended.

1. Using the DVA-1002 with AT&T Dimension, System 85, 75 Horizon, Etc.
a. Clip one end of R10 (as shown to the right).
b. Clip one end of R18 (as shown to the right).
c. Install a 4.7K resistor in the vacant R19 position (as shown to the right).
E. Increasing the Record Time
To change the record time from 32 seconds to 64 seconds, clip one end of R48
(as shown to the right). Important: This will cause the DVA-1002 to record at
HALF the original fidelity.
2. Using the DVA-1002 with an N.E.C. PABX
