DAILY OPERATING
INSTRUCTIONS
In general, the installed DCU is transparent to the user of the
telephone. All incoming calls trigger a pre—defined number of
rings (system default is set at 6 rings) through out the house
before the DCU picks up the call.
Incoming Calls
The central computer may, from time to time, initiate a call to
the DCU. Therefore, the Offender may receive two types of
phone calls; regular calls from other people, and occasional
calls from the central computer.
Accepting an incoming call
The phone will ring up to 6 times, during which the call may be
answered. After 6 rings, the DCU unit will answer and
disconnect the call.
If the Offender hears a light sound on the line during the first
few seconds of the conversation, he/she should not be alarmed.
The DCU automatically interacts with each incoming call for
the first few seconds.
During the conversation the Offender might hear a short tune
from the DCU. This tune indicates that the DCU needs to call
the central computer. In this case, the Offender should complete
his/her conversation as soon as possible to enable the DCU to
make its call.
