Fex21 Top Questions
If the unit has been in
storage, you may need to do a hard reset:
- Caution: Performing a hard reset will destroy all data and programs
stored in memory. If possible, save these items to an external storage
device before proceeding. A hard reset does not affect operating system files,
however the registry will be reset to the factory default.
- Connect the Fex21 to an AC wall charger and press the power key. If
the unit will not turn on, proceed to the next step.
 Hold down both contrast keys, the power key, and the left backlight
key for about 10 seconds. The Fex21 will perform a hard reset and
switch off.- Press the power key to restart the unit.
- If the unit still won't turn on, it will need servicing.
After the unit reboots it
will need to be left on the charger for at least
24 hours so that the internal backup battery has time to recharge.
The serial number is located on the back of the unit
near the backstrap:
- Lightly slide the backstrap to the side of the machine.
- The serial number will begin with the numbers 70000 or 72000.
- Press the CTL+ALT+= keys to display the calibration screen.
- Using a stylus, press and hold each target until the target moves to
a new location. Ensure that only the tip of the stylus touches the
screen during the calibration process. Repeat this process several
time if needed. When calibration is successful, the target will vanish
and further instructions will appear. Proceed to the next step if this
fails.
- Perform a hard reset. See the section above titled 'My Fex21 won't turn on, even
when connected to a AC wall charger'.
- After the Fex21 reboots, attempt to recalibrate the screen again.
- If the unit still won't calibrate, the unit will require a new touch
panel. Contact service to schedule the repair.
