Backup Battery

Your hand-held computer contains a rechargeable nickel-
metal hydride backup battery. This backup battery re-
charges when needed from either an external charging
source (like a printer or dock) or from the main battery
pack. If the backup battery is completely run down it takes
a minimum of 8 hours to completely recharge but it is bet-
ter to recharge it for a full 12 hours.
The backup battery remains ready to protect your
computers data whenever the main battery pack is removed
or needs recharging. The backup battery should last about
500 cycles (discharge and recharge equals a cycle). This
battery should last for about 5 years before it needs to be
replaced. If your hand-held computer fails to hold data for
at least 100 hours in the suspend mode, send your
computers to the Norand Customer Support Center for
replacement.

tional memory, send your hand-held computer into your No-
rand Customer Support Center.
The main memory is protected by the backup battery dur-
ing low or dead main battery conditions or when the main
battery pack is removed.
