LCD screen problems

Adjust the contrast using the contrast

wheel on the right side of Scanner

LCD stands for Liquid Crystal Display, and it is very sensitive to

temperature.

If you have placed Scanner in a cold or hot place, the display may

become too dim or too dark when turned on. This is not a defect of

Scanner itself, but a normal response of all LCD’s to the change of

temperature.

This is not a defect of Scanner.

However, if you cannot control the contrast using the dial, please

The display is too dim or too dark

Adjust the contrast using the contrast

wheel on the right side of Scanner

The LCD unit of Scanner 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 DCN

turned on for more than 2 hours.

This is not a defect of Scanner.

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.
