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.

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.
