B. Accessing the Programming Mode
Step 1. Set DIP switch 2 to ON for the module being programmed..
Step 2. Come off-hook on the observing phone and dial a Q.
Step 3. Two beeps will be heard. (Modules not being programmed - status LED's will turn off)
Step 4. When finished programming, hang-up and set DIP switch 2 to OFF.
Note: For multi-module systems, program each module separately. The status LED for the module being pro-
grammed will remain lit, while all other module's LEDs will turn off.
C. Setting the Number of Digits (for Dial Up Codes)
The dial up codes are factory set to two digits (01-24). Each SO-24A in a multi-module configuration needs to be
programmed with the same number of digits for all dial up codes. To program the number of digits, use the chart
below:
To Program...
... two digit dial up codes
... three digit dial up codes
... four digit dial up codes
Important: All SO-24A's in a system MUST be programmed with the same number of dial up code digits.
D. Dial Up Codes
The SO-24A is factory set with the dial up codes for locations 1-24 factory set to 01-24. The dial up codes may
be programmed to match the extension number of the line/station being observed or any other numbering scheme
as long as all access codes are the same length (see section C). Important: Each module must to be pro-
grammed with its own unique set of dial up codes. Note: When using multiple units, see DOD# 943 for a pro-
gramming chart to manage dial up codes for up to 10 units.
To Program...
...dial up code 231 for
location 03
...dial up code 15 for
location 15
...dial up code 2714 for
location 14
E. Talk Assist
The talk assist feature can be activated any time a location is being observed and a "Q" is dialed at the observing
phone. To prevent accidental talk assist, the feature may be disabled by entering Q0 while in the programming
mode (see section B). Enter Q1 to enable talk assist.

To activate the digital recorder automatically when a station is being observed ........... set DIP switch 3 to ON
From the observing port, any of the stations can be accessed by dialing a programmable 2, 3 or 4 digit Touch Tone
dial up code. Stations being observed are unaware that they are being monitored. Automatic gain control equalizes
in and outbound conversation levels. If assistance is required, the observer can quickly enter the conversation by di-
aling a Touch Tone "Q." An audio out jack provides a microphone level signal for a tape recorder while the record
control jack provides remote operation of the tape recorder on command. Additional SO-24A's may be used to
add 24 additional stations or lines at a time. A multi-module configuration of SO-24A's is capable of supporting
240 lines or stations.
