DVA-1003B
Three Channel
Digital Voice Announcer
July 7, 1998
3 Channel Non-Volatile Digital Voice Announcer
with Remote Recording and Transfer Capabilities
The DVA-1003B is a fully professional, cost-effective three port digital voice announcer,
specifically designed for ACD/UCD, auto attendant, call intercept, night messaging information
provider and other PABX and Centrex announcement applications.
The DVA-1003B will increase call handling capacity by answering incoming calls on demand,
or on the first ring, and automatically adjusts the announce time to the length of the outgoing
message. The DVA-1003B will disconnect on CPC and provide instant “rewind” for the next
caller.
Each of the DVA-1003B’s three channels is factory equipped with 16 seconds of non-volatile
recording memory, expandable to 1 full minute per channel with Viking’s ERAM-60 expansion
kits.

Wire each channel of the DVA-1003B 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-1003B requires a 24 hour unswitched 115V AC outlet. To protect the internal electronics, the
installation of a surge protector is recommended.
B. Installing the ERAM-60
Important: Electronic components are sensitive to static
electricity. Personnel and the work area should be grounded
before handling.
