CARE AND MAINTENANCE
The ProLaser III is designed and constructed so that
only a minimal amount of normal maintenance is
required. Maintenance consists of periodic cleaning of the
external optical surfaces. This should be done only when
necessary, as evidenced by degradation in performance of
the unit or by visible contamination on the optics
surfaces.
CAUTION: The external optical surfaces are coated
glass. Extreme care must be taken when
cleaning these surfaces to prevent scratching
which will lead to performance degradation.
Surfaces that may be cleaned include the laser output
aperture, the HUD combiner glass, and the HUD lens.
Gently brush loose debris from the optical surface to be
cleaned. Then, using a clean, lint-free cloth or lens
cleaning tissue dampened with low-residue isopropyl
alcohol, gently wipe the optical surface with a circular
motion. A cotton swab may facilitate cleaning of the HUD
lens and the lower surface of the HUD combiner glass.
Repeat the cleaning procedure if necessary.
Note: During the lifetime of the instrument, scratches,
pits, and stains may occur on the optical surfaces, which
cannot be removed by cleaning. Excess rubbing should
not be used to attempt to clean these marks; further
damage may result. The ProLaser III will operate
satisfactorily with a limited amount of cosmetic optical
defects.
