replaced. Failure to do this may invalidate the warranty.
TROUBLESHOOTING PROCEDURES
1. Resetting the Display Contrast
For an easier display contrast adjustment it is recommended to reset the factory contrast
setting first. This procedure restores the “center” contrast position and then sets the
maximum and minimum adjustable values to your preferences.
1) Press
simultaneously until
you hear a short beep. The center
contrast value has now been set.
2) See NOTE.
3) Press and hold
until the desired maximum adjustable contrast is reached by
the display.
4) Press
and to store the maximum adjustable contrast value in memory.
A short beep should be heard.
5) Again, press and hold
until the desired minimum adjustable contrast is
reached by the display.
Press
and to store the minimum adjustable contrast value in memory.
A short beep should be heard.
NOTE
If your equipment is a higher serial number than 109.973 or the touch screen has
been substituted after December 2011, the procedure of Resetting the Display Contrast
will leave the brightness very low (blue screen).
