Maintenance and inspections

≥Wipe off any dust or dirt on the monitor and LCD panel with a soft cloth.

For stubborn dirt or stains, wipe the monitor and LCD panel with a cloth that has been lightly dampened with well-diluted kitchen detergent and wrung out thoroughly, then finish it off with a dry cloth. The monitor may malfunction if even one drop of water gets into the internals.

≥Do not use benzine, paint thinners, etc. to clean the monitor.

They may discolour the monitor’s surfaces or cause the paint to peel off.

≥Do not spray detergent or other cleaners directly on the monitor or LCD panel.

The monitor may malfunction if even one drop of water gets into the internals.

In order to ensure that this video component will provide many hours of trouble-free operation, provide the appropriate maintenance and servicing at periodic intervals so that the monitor’s functions will be kept in perfect working order at all times. In order to ensure that the monitor’s functions will perform to the best of their ability for a long time to come, be absolutely sure to conduct the maintenance and inspections described here.

1. Necessity for periodic maintenance and servicing

A backlight power supply is used in this LCD monitor. This part (which is a consumable) will deteriorate over time and lead to a reduced level of performance and failure.

For this reason, do not confine the maintenance activities to the kind of after-sale servicing which is performed when the usual failures have occurred. The user should know that it is important to follow through with comprehensive servicing which involves periodic maintenance and servicing aimed at keeping up the performance that the monitor is designed to provide and preventing sudden failures caused by consumable parts, etc.

2. Maintenance timeframe and implementation item

The maintenance implementation time given below is provided as a standard guideline, and it does not represent the service life of the part concerned. It should also be borne in mind that the period over which the part’s performance will deteriorate differs according to the operating environment and method.

Part	Quantity	Periodic maintenance/inspection and time (hours)
Backlight	1	Replace every 38,000 hours.
