Oracle Vacuum Cleaner CPU-56T User Manual

The battery provides data retention of seven years summing up all periods of actual data
use. Force Computers therefore assumes that there usually is no need to exchange the
battery except, for example, in case of long−term spare part handling.

S Board/System damage

Incorrect exchange of lithium batteries can result in a hazardous explosion.
Therefore, exchange the battery as described in this chapter.

S Data loss

If the battery does not provide enough power anymore, the RTC is initialized and
the data in the NVRAM is lost. Therefore, exchange the battery before seven years
of actual battery use have elapsed.

S Data loss

Exchanging the battery always results in data loss of the devices which use the
battery as power backup. Therefore, back up affected data before exchanging the
battery.

S Data loss

If installing another battery type than is mounted at board delivery may cause data
loss since other battery types may be specified for other environments or may have
a shorter lifetime. Therefore, only use the same type of lithium battery as is already
installed.
