You may see some variance in the 
responsiveness and accuracy of the touch-
screen when using it in cold or hot
environments. For example, when pressing
the touchscreen you might: 

●

Not see a response

●

Need to press a menu command or
button hard to make it work

●

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 cali-
brating 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.

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.

●

To quickly adjust the contrast at any time,
press and hold down the backlight button as
you roll the selector wheel.

●

Turn on the backlight and check the contrast of
your display to ensure that the setting works in
a darkened room.
