Maintenance
There is very little involved with the care and maintenance of
your DP5100. However, common sense and periodic main-
tenance will ensure top performance.
The lamp, lenses, mirrors, and LCD panels have been carefully
aligned at the factory to give you the clearest, brightest image
possible. However, physical abuse can cause misalignment or
damage to the optical elements. Take appropriate care in use and
handling.
CAUTION! The DP5100 contains sensitive circuitry and
optics. Protect it from potential fluid spills.
From time to time, youÕll need to clean the optics on the lens.
1. Take a piece of lens tissue and form it into a loose swab. Wet it
with lens cleaning fluid or denatured alcohol and gently move
it over the lens surface.
CAUTION! Never use acetone to clean the lensÑit can
remove the paint from the metal around the lens or the mirror
mount, and leave a residue on the glass surface.
2. Take another part of the lens tissue not touched by your bare
fingers and repeat the process, going over the lens in another
direction.
CAUTION! NEVER look directly into the lens when the
lamp is on. The brightness can damage your eyes. To check for
smudges, look at the lens from an angle.
3. Repeat steps 1 and 2 until no smudges or particles can be seen
when the lens is illuminated by a strong light. If the lens is
extremely dirty, it may be necessary to use several pieces of lens
tissue. Use water if denatured alcohol is unavailable.
