Calibrating the Touchscreen
You may see some variance in the
responsiveness and accuracy of the
touchscreen when using it in cold or hot
environments. For example, when press-
ing the touchscreen you might:
l
Not see a response
l
Need to press a menu command or
button hard to make it work
l
Touch an area beside a button—not
directly on it—to make it work.
If you can’t lightly touch a menu com-
mand or button to make it work, then
calibrating the touchscreen may help.
To calibrate the touchscreen:
1 On the Home menu, select TC1000
Settings.
2 Select Calibrate touchscreen, and
then press the button in each corner
of the touchscreen.
Adjusting the Touchscreen Contrast
You can adjust the contrast of the touch-
screen to view the display more easily.
To adjust the touchscreen contrast:
1 On the Home menu, select TC1000
Settings.
2 Select Set display contrast, and then
follow the on-screen instructions.
Tips
l
To quickly adjust the contrast at any time, press
and hold down the backlight button as you roll
the selector wheel.
l
Turn on the backlight and check the contrast of
your display to ensure that the setting works in
a darkened room.
