Battery Replacement

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. You should install
fresh batteries every year.
Battery Replacement
1 1
The PARTNER ACS 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. Users at these extensions should be instructed to notify you when they see
this message. You should replace the batteries within 45 days of seeing the message.
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.
Also, the settings retained in the 1600 DSL module’s flash memory become the active
settings when the power is turned off and back on. 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 2-11 .)
The message may flicker on and off as the batteries approach the low-power threshold.
The PARTNER ACS Release 3.0 or later includes a PARTNER Remote Access PC Card,
which allows you to program the system remotely or locally from a PC and perform
backup and restore functions. The PARTNER Remote Access PC Card is a PCMCIA
card that can also be used to upgrade previous versions of PARTNER ACS to Release
3.0 or later. You must have additional PARTNER Remote PC-Software to program the
system from a PC.
