Cleaning Or Replacing The Filter

The air-filter sponge keeps the inside of the MultiSync MT830/ 1030 LCD Projector free from dust or dirt and should be cleaned after every 100 hours of operation (more often in dusty conditions). If the filter is dirty or clogged, your projector may overheat.

NOTE: Clean your filter after every 100 hours of operation.

CAUTION

Turn off the main power and unplug the projector before replacing the filter.

Only clean the outside of the filter cover with a vacuum cleaner.

Do not attempt to operate the projector without a filter cover.

Your LCD projector will not operate unless the filter cover is installed correctly.

To clean the air-filter:

Vacuum the filter through the filter cover.

To replace the air-filter:

1.Remove the filter cover by pushing up on the catch of the cover with a flat-head screwdriver until you feel it detach.

2.Reinstall the new filter cover.

NOTE: Do not detach the sponge from the filter cover. Do not wash the filter cover with soap and water. Soap and water will damage the filter membrane.

Before replacing the filter cover, remove dust and dirt from the projector cabinet. Keep out dust and dirt during filter replacement.

Remote Control Battery Installation

1.Press firmly and slide the battery cover off.

2.Remove both old batteries and install new ones (AA). En- sure that you have the batteries' polarity (+/–) aligned cor- rectly.

3.Slip the cover back over the batteries until it snaps into place.
