Caring for your R12
Cleaning the fingerprint reader 59
With typical use, you should change the pen tip every 90 days. If you use the pen in a dirty
or dusty environment, you should change the pen tip every 30 days. Particles can become
embedded in the pen tip and scratch the display.
To replace the pen tip:
1. Grasp the old tip with the replacement tool. Use the notch on the ring to grab the tip.
2. Pull the old tip out of the pen.
3. Insert a new tip, placing the flat end of the pen tip in first.
4. Apply slight pressure to push the tip in to place.
Cleaning the fingerprint reader
Under normal circumstances, you should clean the fingerprint reader once a month, or
whenever necessary.
To clean the fingerprint reader, gently rub the sensor surface with the cloth that is included
with the tablet or any microfiber cloth.
WARNING:
Don’t use bleach, solvents, or abrasives. Don’t spray or pour any liquid directly
on the sensor.
Caring for the tablet battery
To maximize the performance of the battery, condition the battery once a month. To
condition it, run the tablet on battery power until the battery’s charge level drops below
20%. Then use AC power until it is fully charged.
