FUSE
• Changing the lamp (MINISCAN 300)
Open the projector, loosen the two side nuts (11) of the lamp to be changed and
remove it from the supports (12).
Remove the new lamp from its packaging, loosen the two side nuts (11) and locate
the lamp in the supports (12). Finally, retighten the nuts.
IMPORTANT: for uniform distribution of the light beam, the lamp must be positioned
so that the glass pip (13), on the bulb does not coincide with the optical axis of the
projector. With this in mind, locate the pip as high up as possible.
CAUTION: The projector uses a high pressure discharge lamp with
external starter.
• Routine cleaning
To maintain the light output of the projector undiminished, parts that tend to accu-
mulate dust and grease must be cleaned periodically.
In most circumstances, the projector will give long and trouble-free service if these
simple guidelines are followed.
To remove dirt from the lenses and filters, use a soft cloth moistened with any liquid
detergent suitable for cleaning glass.
IMPORTANT: do not use solvents or alcohol
Parts that need cleaning frequently.
Parts that need cleaning monthly.
Internal components should also be given a general clean once a year, dislodging
dust and dirt with a brush and removing it simultaneously with a vacuum cleaner.
• Replacing fuses
To change the fuses, press the tab (14) and
pull out the fuse holder (15). Replace any
blown fuse with one of the same type and rat-
ing as indicated on the label (16) attached to
the holder (15). Insert the fuse holder and
push in to engage the tab (14).
CAUTION:
- When fitting a new lamp, read the manufacturer’s instructions carefully.
- The lamp must always be changed without delay if damaged or deformed by heat.
