pacity when two of the contacts are touched at the same

If your hand-held computer goes into a shutdown mode be-
cause of low battery condition, data is protected by the
backup battery. Your computer contains two 100 mA hour
vanadium lithium backup batteries. The backup battery
charges itself from the main pack or a charging source so it
is constantly ready to take over data protection.
This user’s guide will occasionally use the term “cycles”
when presenting rechargeable battery instructions. Cycles,
are the number of times the rechargeable battery pack can
be charged and discharged during the life of battery. The
Lithium Ion rechargeable battery design, used in the main
pack, should give you approximately 500 cycles of use.
There are no guarantees on this number because it depends
greatly on how the battery pack is used and cared for.
Memory
Three types of memory are available with this computer:
" Main Memory DRAM
" Flash ROM
" PC Cards
Main Memory
Standard main memory DRAM configuration is 8 mega-
bytes (MB), this can be extended to 16, or 32 MBs. Main
memory was ordered at the time your unit was purchased.
You are able to upgrade to a larger memory size by having a
new memory board installed at your Customer Support
Center.
The main memory is protected by the backup battery dur-
ing low main battery conditions or when the main battery
pack is removed.
