Cleaning Or Replacing The Filter

The air-filter sponge keeps the inside of the MultiSync MT1020G/

820G 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 LCD projector and wait for the fan to stop. 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.

• Your LCD projector will not operate unless the filter is in-

stalled correctly.

• Do not put the LCD projector on end except to replace the

filter.

To clean the air-filter:

1. Turn over the projector. Put the LCD projector on end so that the

bottom is visible.

2. Vacuum the filter through the filter cover.

3. Place the projector back in a horizontal position.

To replace the air-filter:

1. Remove the filter panel by pushing up on the catch of the cover

with a flat-head phillips until you feel it detach.

2. Remove the filter and replace it.

3. Reinstall the filter panel.

NOTE: Do not detach the sponge from the filter cover. Do not wash the

filter with soap and water. Soap and water will damage the filter

membrane.

Before replacing the air-filter, remove dust and dirt from the

projector cabinet. Keep them out during filter replacement.

Remote Control Battery Installation

1. Press firmly and slide the battery cover off.

2. Remove all two old batteries and install new ones (AA). Ensure

that you have the batteries' polarity (+/–) aligned correctly.

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