There are some extremely important points to remember
when installing new batteries:
☞
• Do not remove the operating and backup batteries
at the same time. Doing so will result in the loss of
all data stored in the unit’s memory.
• Backup all important data before replacing the
batteries.
• Replace the two operating batteries at the same
time with new batteries of the same type.
• The memory backup battery installed at the factory
at the time of manufacture may have become
depleted during shipment and may not have the full
battery life indicated in the specifications.
