Replacing the Battery
The lithium battery on the main board powers the real-time clock (RTC) for three to four years
in the absence of power. When the battery weakens, the loss of voltage will cause the system
settings and selections stored in CMOS RAM and Real Time Clock (such as the date and time)
to loose their preselected values. Contact your customer service representative or dealer for a
list of approved replacement batteries.
The following warning and translations are required by specific certifying agencies to be
printed immediately adjacent to the procedure for removing the battery.
WARNING
Danger of explosion if battery is incorrectly replaced. Replace only
with the same or equivalent type recommended by the equipment
manufacturer. Discard used batteries according to manufacturer’s
instructions.
