Replacing the CMOS Battery

The lithium CMOS battery on the workstation board powers the RTC (Real-Time Clock) in the absence of
power. When the battery starts to weaken, it loses voltage, and the system settings stored in CMOS RAM in
the RTC (for example, the date and time) may be wrong. Contact your customer service representative or
dealer for a list of approved devices.
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.
