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 Advanced 
Communications System Release 1.0). To determine the release 
number, press 
f 5 9
at any display phone.
■
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 either on the 
upper right-hand corner of the phone or on the dialpad overlay.
■
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 two lines on the PARTNER 
Advanced Communications System module or the 308EC module automatically 
connect to the first two extensions on the module, and the first line on each 206 
module connects to its first extension.
This enables 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 a minimum of 45 days and a maximum of 
six months after it stops receiving power, depending on the freshness of the 
batteries. When the batteries are drained, all of the system’s programmed settings 
return to the factory settings. It is recommended that you install fresh batteries 
every year. See ‘‘Battery Replacement’’ on page 6-2 for more information.
Battery Replacement
!
CAUTION:
Do not turn off the power or remove the processor module before 
replacing the batteries! If you do, all settings for system and 
telephone programming will revert to the default settings. If you have 
a Backup/Restore PC Card, it is highly recommended that you do a 
backup before changing the batteries.
