Preventive Maintenance
The real-time clock contains a lithium battery which should be replaced
once a year. The real-time clock is located on the system interface board.
Although the battery is available from Hewlett-Packard, it usually can
be obtained locally. It is a 3V, 160 mAh battery.

Panasonic
Part Number

WARNING
Battery may explode if mistreated. Do not re-
charge, disassemble or dispose of in fire.
When changing the battery, remember that the real-time clock will reset
to its default state, and it is necessary to set it to the current time. Note
also that the battery retainer clip is a conductor, and merely lifting it
up without changing the battery will still cause the real-time clock to
reset.
