Battery Replacement

The processor module uses two user-replaceable AAA alkaline batteries. These batteries provide enough power to retain the system programming settings during a power failure for 45 days to six months, depending on the freshness of the batteries. When battery power is getting low, the system displays a ChgBat W/PowerOn or ReplaceSysBat W/Power On message on the top line of display telephones at extensions 10 and 11 in place of the default day/date/time message. You should replace the batteries within 45 days of seeing the message.

The message may flicker on and off as the batteries approach the low-power threshold.

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 revert to the factory settings. If you have a Backup/Restore PC Card, do a backup before changing the batteries.

Change the batteries in the processor module every year, even if the system has not yet displayed the ReplaceSysBat W/Power On message. Choose good quality alkaline batteries. (See “Inserting Batteries in the Processor Module” on page 19.)
