Chapter 4 Care and Maintenance 61
Cleaning the fingerprint reader
Under normal circumstances, you should clean the fingerprint reader once a month, or
whenever necessary.
To clean the fingerprint reader
1. Shut down the system, unplug it, and remove the battery.
2. Lightly spray a cotton swab with household window cleaner.
3. Gently rub the sensor surface with the cotton swab, slowly rotating the swab so a new,
clean surface of the swab is constantly exposed to the sensor surface. Do not allow
cleaner to drip or run down into the electronics around the sensor.
Do not use bleach, solvents, or abrasives. Do not spray or pour any liquid directly on the
sensor.
4. After cleaning, gently rub the surfaces again with a clean, dry cotton swab. Use a clean
swab each time you clean the sensor.
Pen
• Store the pen in the pen holder or in a case when not in use.
• Do not store the pen vertically on the tip. Constant pressure on the tip can affect the
pen-to-digitizer interaction.
• Change the pen tip regularly. See “Replacing pen tips” on page 62.
• Do not immerse the pen in liquid. It contains electronic components that could be
damaged.
• In certain environments, particles or debris can stick to the pen tip or the display. To
avoid damaging the display, clean it frequently with the provided cleaning cloth. Also,
change pen tips regularly, especially if you drop the pen onto a rough surface that could
damage the tip or embed debris in it. Damaged pen tips can scratch the display.
