Restoring Factory Default State
In some cases, you may need to restore your Pocket PC to the factory default
state by clearing the memory (RAM) from your Pocket PC. For example, you
should clear the memory:

When your Pocket PC does not respond after being reset.
When you forget your password.
Clearing the memory means all data you have entered in RAM, including all
files, system settings and additional programs you have installed, will be erased.
(Programs installed to ROM at the factory are not affected.)

Follow this procedure to clear the memory from your Pocket PC:

3. Stop all running programs by tapping > Settings > System tab > Memory icon > Running Programs tab > Stop All.
4. Press the battery lock to remove the battery.
5. Use the stylus to slide the battery switch to the OFF (left) position.
6. Wait for 1 minute and then slide the switch back to the ON (right) position.

NOTE: In case your Pocket PC didn’t automatically turn on, use the stylus to firmly press the RESET button at the back
of your Pocket PC to turn it on.
8. To begin the Welcome Wizard, tap the screen with the stylus and follow the
