When You Need Help

If you have a problem with your system, you may be able to solve it yourself by
following the appropriate troubleshooting procedures described in this chapter.
If not, you can call for help: in the continental U.S., call the Helpline at 1 800
628-2888; outside the continental U.S., call your AT&T Authorized Dealer.
If you call, have the following information ready so that the representative can
better help you:
The kind of system you have (for example, PARTNER Release 3)
The number of lines and extensions in your system
The type of phone (system or standard) and the model number, if
applicable. (System phone model numbers are located on the upper
right-hand corner of the phone—MLS-18D, MLS-12D, MLS-12, MLS-6,
or MLC-6.)
If you followed a troubleshooting procedure, tell the representative what
you did.

Power Failure Operation

When power to the system is cut off, the first line on each 206 module
automatically connects to the first extension on the module. This allows you to
make and answer calls during a power outage, provided you have a standard
phone connected to one of these extensions. (During a power failure, only
standard phones can make and receive calls—other system features are not
available.)
The system can retain option settings for approximately four days after it stops
receiving power. After four days elapse, all of the system's settings return to the
factory settings.
