In The Event Of Telephone Operational Problems
In the event of telephone operational problems, disconnect the control from the phone line by
removing the plug from the phone wall jack. We recommend that your installer demonstrate this
disconnection on installation of the system. Do not attempt to disconnect the phone connection
inside the control. Doing so will result in the loss of your phone lines. If the regular phones work
correctly after the control has been disconnected from the phone wall jack, the control has a
problem and you should immediately call for service. If upon disconnection of the control, there is
still a problem on the phone line, notify the Telephone Company that they have a problem and
request prompt phone repair service. The user may not under any circumstances attempt any
service or repairs to the security system. Repairs must be made only by authorized service (see
the LIMITED WARRANTY statement for information on how to obtain service).
