The Scrambler ACS-2 by Research Electronics Inc. | Made in Korea
(This item is brand new in the box!)
ACS-2 is a digitally controlled analogue voice scrambler
for regular telephone sets,
developed in the early 1990s by Research Electronics Inc. (REI)
in Algood (Tenesee, USA). The portable unit was intended for use in
combination with the handset of a regular (analogue) desktop telephone set..
The device roughly measures 19.5 x 6.5 x 6 cm and weights approx.
250 grams. It resembles the handset of an old regular telephone set,
with a microphone at the bottom, a speaker at the top, and
6 push-buttons and 4 indicators inbetween.
The ACS-2 is powered by a single 9V battery that is installed at the rear,
and offers 58,488 code settings, divided over 4 factory controlled banks.
To set up a connection, one needs two ACS-2 devices from the same bank (marked A,B, C or D respectively)
and set the
DIP switches in the battery compartment to the same positions.
