Troubleshooting the System
This chapter provides procedures for solving the most common problems that
you may encounter with the system. You may be able to resolve a problem
quickly and easily by following the appropriate steps in this chapter.
NOTE:
See the Data/Video Reference for information about troubleshooting data and
video communications.
You will find it helpful to have the Feature Reference , System Programming , and
the system planning forms at hand to perform some of the procedures. If the
procedure involves using system programming or centralized telephone
programming to check a system or feature setting, the troubleshooting
procedures indicate where in System Programming you can find the
programming steps.
You should also have the System Information Sheet at the front of this guide.

WARNING:
If you must check something on the control unit, proceed with caution.
Avoid standing on a box or chair to reach the unit if it is installed out of
easy reach. If you do not have a stable ladder or other proper equipment,
do not proceed; wait for the AT&T technician.
