If the batteries become weaker (the alarm or the key beep does not
sound), the power may go off during operation or the Organizer may
fail to turn on. The memory contents will still be retained by the
memory backup battery. Replace the operating batteries to avoid loss
or alteration of data.
Precautions on battery use
Always replace both operating batteries at the same time. Do not use
an old battery and a new one together. Use only the specified lithium
batteries.
Replace the memory backup battery at lease every 5 years. The
original batteries were installed in the factory at the time of shipment
and might be depleted before satisfying the operating time indicated in
the specifications.
Battery precautions
• Keep the batteries out of the reach of children.
• When batteries become weak, remove them from the Organizer
immediately. If depleted batteries are left in the Organizer for any length
of time, they might leak and cause corrosion inside the Organizer.
• Do not dispose of batteries by fire as they may explode.
