WARNING
RAM cards have a limited battery lifetime and data will be lost from the card
when the battery expires. The battery is used whenever the card is removed
from the analyzer. Consult Table 9 in the Maintenance Chapter for the
approximate lifetimes of RAM card batteries. To avoid losing data, do not let
the RAM card stand unplugged from the analyzer for an extended period.
RAM Card Battery Maintenance
When the RAM card is removed from the analyzer, an internal battery provides
the power to maintain the data. As indicated in Table 9, the battery must be
replaced to retain data on the card if the card is in the analyzer and the battery
is low. Error Message #29 will be displayed at power up when it is time to
change the battery. Replacement batteries should be available at local
electronics stores.
To change the battery:
1. Follow the procedure described above for removing the RAM card
from the analyzer.
