4. Resetting the D3 POS
When the D3 POS 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 Soft reset before initiating a Hard 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.
4.1 Soft Reset
When you should perform the soft reset?
When you cannot turn on or off a program, or execute other programs because of “ hang”-
the system error that stops responding. The “ soft reset” for recovering the D3 POS is to

will be saved, so transactional data maybe lost during the reset.
Procedure to Soft Reset. To initialize soft reset, press and hold the <Reset> key.
After Soft Reset
• The splash screen will appear shortly.
• The desktop appears with the application shortcuts on the screen.
• The custom settings in the registry are persistent.
• The RF Network PC Card if present, connects to the network system.
4.2 Hard Reset (cold reset)
When you should perform the cold reset?
If the performed reset method fails to restore system operation, it may be necessary to
perform a hard reset. This is a boot method that formats the object store to clean data and
registry information from the D3 POS system and restores them to their factory-default state.
This will erase the memory in the D3 POS, 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.
After Hard Reset.
When a PDA goes through the Hard reset sequence, it clears the working RAM and initializes
the file system.
• The splash screen will appear shortly.
• You will be asked to recalibrate the touch screen. Press the <ESC> key to circumvent
