Resetting the Device
There are three kinds of reset that you can perform on your device when the device’s operating system
stops responding or the system becomes corrupted. Depending on the situation, a warm boot, clean
boot, or cold boot can be performed.
Warm Boot
You may have to perform a warm boot if the device freezes (i.e., device no longer responds to the
tapping on the screen).
To perform a warm boot:
A warm boot or soft reset allows your device to get a fresh start, similar to rebooting a computer. This
will restart your device and adjust memory allocation. All records and entries are retained after a warm
boot. Unsaved data in open programs may in some cases be lost.
1. Remove the stylus from its holder.
2. Lightly press the tip of the stylus to the Reset button located on the rear of the device.
Clean Boot
A clean boot allows your device will do a registry cleanup and reset all the system to the factory default.
To perform a clean boot:
1. Hold down the right and left scanner trigger buttons.
2. While holding down the scanner trigger buttons, gently press the tip of the stylus to the reset
button located on the rear of the device.
