Backup Copies of All Important Data
Caution
Note that CASIO Computer Co., Ltd. shall not be held liable to you or any
third party for any damages or loss caused by deletion or corruption of data
due to use of the Handheld Terminal, malfunction or repair of the Handheld
Terminal or its peripherals, or due to the batteries going dead.
The Handheld Terminal employs electronic memory to store data, which
means that memory contents can be corrupted or deleted if power is
interrupted due to the batteries going dead or incorrect battery replacement
procedures. Data cannot be recovered once it is lost or corrupted. Be sure to
make backup copies of all important data. One way to do this is to use the
separately sold cradles to transfer data to a computer.
