Maintenance inspecions

Maintenance inspections through periodic and appropriate maintenance are essential to keep the monitor in optimum condition and ensure safe operation. Be sure to conduct the following maintenance inspections to enable long-term, full use of all its functions.

Necessity of periodic maintenance service

The backlight in the LCD panel is a consumable component that deteriorates over time leading to gradual loss of performance that could eventually result in a malfunction.

Conventional after-sales service that replaces parts when they break down should therefore be combined with a regularly conducted comprehensive service to maintain normal operation and prevent unforeseen breakdown of consumables.

Maintenance

Clean the cabinet and protection panel by gently wiping it with a soft cloth.

To remove stubborn soiling, use a cloth dampened in a weak neutral detergent solution and thoroughly wrung out. Then wipe with a dry cloth. Any moisture entering the monitor could damage it.

Do not use benzene, thinner and similar solvents for cleaning. They could discolor the surface and cause the paint to peel.

Do not directly expose the monitor to spray cleaning. Any moisture entering the monitor could damage it.
