AT570W
4. Resetting the PDA
When the AT-570W completely stops responding for your command, or an application is
locked up and does not respond, and when you want to upgrade the firmware, it may be
necessary to perform a reset.
Caution
Always attempt a Warm reset before initiating a Cold reset. Once you initiate a cold reset, all
applications are forcibly closed and working RAM and files are cleared.
It is a good idea to store important data in the resident (Flash Disk) for this reason.
Warning
Do not use force or a sharp object like paper clip to press the reset button. Use the stylus for
that purpose. Sharp object like paper clip could puncture the seal of the reset key.

perform a hard reset. This is a boot method that formats the object store to clean data and
registry information from the AT-570W system and restores them to their factory-default
state.
This will erase the memory in the AT-570W, including all applications and data files found in
the object store (user store).
A Hard reset is a complete reset of the PDA in which all applications are forcibly closed and
working RAM and files are cleared.
Hard Reset Procedure. To perform a Hard reset, simultaneously press the <Reset> key with
the stylus while pressing the <power> key.
