Calibrating the touch screen
About this task
Use screen calibration for alignment of the touch screen of 9621G and 9641G deskphones. Use a
stylus instead of your finger to touch the calibration points precisely. The CLEAR Craft procedure
clears any calibration data set using the Craft Procedures screen, but does not change factory
settings of calibration data. Use the Default softkey to restore factory-set calibration. You cannot
save calibration results as part of a backup operation. 9641GS deskphones do not support screen
calibration.
Procedure
1. Select CALIBRATION from the Craft Procedures screen.
The telephone displays three softkeys Start, Default, and Cancel.
2. Touch Start to calibrate the screen.
The screen displays a calibration target with a plus sign (+) at a particular point.
3. Touch the center of the target with the stylus as soon as the target appears.
The target disappears, and a new target appears in a different part of the screen.
4. Touch the center of each target with the stylus within 10 seconds of its appearance.
After you touch all the five targets, the system plays a confirmation tone sound and
displays Calibration successful. Press Save to store the new
calibration data message.
5. Touch Save to return to the Craft Procedures screen.
The system stores the calibration results in the nonvolatile memory of the telephone.

9600 Series IP Deskphonesor any non-color IP deskphone. The 9611G, 9621G, 9641, and
9641GS each have a color display, and contrast adjustment is not applicable. Fifteen contrast
levels are available.

deskphone, touching the line you want to change or the applicable softkey produces the same
result as selecting a line and pressing the applicable softkey on a non-touch screen IP deskphone.
