LCD screen problems
Adjust the contrast using the contrast
wheel on the right side of Multiscan
LCD stands for Liquid Crystal Display, and it is very sensitive to
temperature.
If you have placed Multiscan in a cold or hot place, the display may
become too dim or too dark when turned on. This is not a defect of
Multiscan, but a normal response of all LCD’s to the change of
temperature.
However, if you cannot control the contrast using the dial, please
contact us for further assistance.
The display is too dim or too dark
Adjust the contrast using the contrast
wheel on the right side of Multiscan
The LCD unit of Multiscan has a backlight for brighter display. This
backlight generates heat as time elapses when turned on.
As mentioned above, because LCD is sensitive to temperature, the
part of the LCD near the backlight may turn dark when you keep
Multiscan turned on for more than 2 hours.
This is not a defect of Multiscan.
However, if the LCD becomes dark too early or the contrast adjustment
doesn’t work, please contact us for further assistance.
A part of LCD became very dark
Report to your local distributor
If the problem is too serious to use properly or the contrast
dial does not function, report the symptoms to your local
distributor and wait for instruction.
Replacement of the LCD module may be necessary.
