3. Perform the calibration steps according to the instructions on the screen. The
calibration utility displays cross-hairs in each corner of the screen, one at a time.
Tap the center of each cross-hair as it appears, holding the pen the same way you
would hold it while using the pen tablet.
4. After you have tapped all of the cross-hairs, a box appears with three buttons. Tap
one of these buttons to accept, cancel, or retry your calibration settings. If you
don’t tap any of the buttons within 20 seconds, the Point 510 pen tablet goes back
to the previous calibration settings. The buttons are:
OK: If you are satisfied that you tapped the cross-hairs accurately, tap OK. Your
taps are then used to calibrate the screen.
Cancel: If you do not want to use your taps to calibrate the screen, tap Cancel. Your
taps are not used and the previous settings are used.
Recalibrate: If you want to try again, tap Recalibrate. The calibration instructions
reappear.
Solving Problems 3
Solutions to some common problems are described in this section. If you are

the actions described, contact the computer professional at your site who maintains
the Point 510 pen tablets.

Suspended Pen Tablet Will Not Resume 3

If the Point 510 pen tablet will not resume operation after operation was suspended,
check the following possible causes:
The Point 510 battery pack might be defective, or discharged to the critically low
level. When the battery pack cannot supply adequate power, the pen tablet is
forced into suspend mode to avoid a total power failure. To correct this problem,
either connect an external power supply (such as the AC adapter or charging
cradle) or install a charged battery pack in the Point 510 pen tablet.
The pen tablet might be too hot. To avoid damage to heat-sensitive components,
the pen tablet enters suspend mode if it gets too hot. The Point 510 pen tablet
cannot resume operation until it cools off to a predetermined temperature. Move
the pen tablet to a cooler location and prevent direct sunlight from shining on it.
