1–5.0 CARE AND MAINTENANCE
Clean the acrylic lower dome as necessary to maintain
a clear picture. Be careful not to scratch the surfaces of
the dome.
Exterior Surface - Clean the dome's exterior surface
with a nonabrasive cleaning cloth and cleaning agent
that is safe for acrylic plastic. Either liquid or spray
cleaner/wax suitable for fine furniture is acceptable.
Interior Surface (Except Chrome) - Clean the same
as the exterior surface.
Interior Surface (Chrome) - The inside surface of a
chrome dome is easily scratched. Use the following pre-
cautions to maintain the dome's surface.
a. Always handle the dome from the outside of its
circular flange.
b. Never touch the coated inside surface. The acid in
your fingerprints will eventually etch the coating
if the fingerprints are not carefully removed ac-
cording to the recommended cleaning procedure
in item “e.”
c. If dust or other contaminants accumulate on the
dome's interior, remove the debris with compressed
air. Compressed air cans are available from photo-
graphic equipment or electronic supply dealers.
d. If heavy residue accumulates and cannot be re-
moved with air pressure, rinse with water and im-
mediately dry with air pressure so that water spots
will not remain. Avoid wiping the coated surface
with direct hand pressure - it will easily abrade un-
less extreme care is taken. Once scratched, the
dome cannot be recoated.
e. If internal wiping is necessary, avoid hand rubbing.
Instead, make a wick as follows:
Use a very soft paper towel. Roll a section into a
tightly wound tube. Tear the tube in half, and wet
the fuzzy end of the wick with a solution of
isopropyl alcohol diluted with water. Hold the dome
with its opening facing downward and wipe the
interior of the dome with the wet end of the wick.
Use a circular motion, starting from the outside
and spiraling into the center. Use a new wick for
each two passes over the dome.
