CALIBRATION
TOUCH SENSE CALIBRATION
The accuracy of triggering a
Hot-Spot
associated to a GTL (Graphical Touch-Link) can be calibrated using
the enclosed
Calibration Stylus
(Part No. XXXX).
Note: Beta Units will not come with Stylus. Please use and PDA stylus or other similarly sized blunt
pointing device for the following.
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 screen with your finger, gently depress the RESET button (
Figure 3 –
8)
of the display with the enclosed stylus.
4. Keep pressure on the screen while the SPLCD is rebooting. After approximately 3 seconds, the
backlight will illuminate.
5. Release the screen and a black ‘dot’ should appear on the side opposite 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 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 the third calibration point, 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 3 thru 8.
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 cleaner. No liquid
cleanser is 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.
