When You Need Help
If you should have a problem with your system, you may be able to solve it
yourself by following the appropriate troubleshooting procedures described in
this appendix. 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 representatives can
better help you:
■
■
■
The kind of system you have (for example, PARTNER
II,
Release 3)
The number of lines and extensions in your system
The model number of the problem phone, if applicable (located on the
upper right-hand corner of the phone—MLS-34D, MLS-18D, MLS-12D,
MLS-12, MLS-6, or MLC-6).
If you followed a troubleshooting procedure and need more help, 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 any of these extensions. (During a power failure, standard
phones can only make and receive calls—other system features are not
available.)
The system can stay programmed for approximately four days after it stops
receiving power. After four days elapse, all of the system’s programmed
settings return to the factory settings.
