The
SO-24A
provides balanced 40V talk battery with dial tone on the observing wire pair. A manager or training
supervisor may access the
SO-24A
observing port dial tone from an unused trunk input on any PABX/KSU or via
a dedicated Touch Tone phone. The
SO-24A
may also be remotely accessed through the
RAD-AMP
Remote Ac-
cess Devices, for more information on the
RAD-AMP
, see
DOD# 415
.
A. Accessing the SO-24A
Once the observing port is accessed, dial any of the twenty-four to two hundred forty lines or stations by dialing
the two, three or four digit dial up code programmed to that station (see Installation chart). Nothing can be heard
by the station being observed. Another station may be selected by dialing a “
#
” followed by another two, three or
four digit dial up code. You may also hang up and then re-access the observing port to dial another dial up code.
B. Selecting a Line or Station
Though the
SO-24A
monitors silently, a manager may enter the conversation to provide assistance at any time
by dialing a “
Q
.” To prevent accidental interruptions, this feature may be disabled (see
Programming
section
E
).
C. Talk Assist
A remotely controllable digital recorder may be started and stopped when interfaced with the
SO-24A
using the
provided cables (see
Installation
). To start the recorder, dial a Touch Tone “
9
.” To stop the recorder, dial a Touch
Tone “
#
” or hang up.
D. Manually Controlled Digital Recording
6
Applications
Set DIP switch
3
to
ON
(see
Programming
section
A
) and all monitored conversations will be recorded. If a multi-
module system (Master and Slaves) is installed, set DIP switch
3
on all modules to
ON
.
E. Automatic Tape Recording
The status LED will turn off when a Touch Tone is present from the observing phone, and will wink once per second
while observing a station.

G. Quick Operation Guide
The
SO-24A
may be used remotely by adding the
RAD-AMP
to the monitoring output.
Important:
When using
this combination, the
SO-24A
dial up codes can
NOT
begin with the number 7. This is because “#7” is the hang-
up command for the
RAD-AMP
.
