CALIBRATION

TOUCH SENSE CALIBRATION

The accuracy of triggering a Hot-Spot associated to a GTL (Graphical Touch-Link) can be calibrated using a
dull blunt object such as a Stylus from a PDA. The smaller the diameter of the calibration tool, the more
accurate the settings will be, thereby setting the SPLCD to optimum performance.
NOTE: When calibrating a SLPCDG/V, use your finger instead of a stylus.
To enter Calibration Mode:
1. Power ON the SPLCD and allow to boot.
2. With the backlight out, press and hold any area of the Touch Screen display with your finger. If the display
is active (i.e. backlight ON), simply press and hold an area without an active GTL.
3. While keeping contact on the Touch Screen with your finger, gently press & hold the Reset Button
(Figures 2a & b –Item 8) on the display with the stylus.
4. Keep pressure on the screen while the SPLCD is rebooting, approximately 6 seconds, until a white screen
with a black dot appears.
5. Release the screen. The black dot should appear on the same side as the built in IR Receiver.
6. With the stylus touch the center of the dot and release.
7. Another calibration dot will appear towards the top middle of the screen. Again, touch the center of the dot
and release. One more calibration dot will appear. Repeat as above. (There a total of three calibration
points).
After touching the third calibration point with the stylus, you can test the accuracy of the calibration. Simply
touch anywhere on the screen and a dot will appear in that touched location. If the dot appears far from the
touch-point location, repeat Steps 2-7.
Exiting Calibration Mode:
After 10 seconds of no activity, the SPLCD will automatically return to normal operation.

MAINTENANCE

CLEANING

The SPLCD should be cleaned with a non-abrasive cloth such as that used for eye-glass cleaning. No liquid
cleanser should be used directly on the display. If the unit is powered OFF, gently wipe the face of the display
so no fingerprints or dust can be seen.
If the unit is powered ON (active), simply press and hold an area of the SPLCD Display with no active GTL's.
While holding this area, gently wipe the rest of the display as noted above.
