Taking Care of your Prisma
Do not touch the lens. Dirt on the lens will appear as
a blurred or dim image or as fuzzy spots on the
screen. If you believe the lens is dirty, it can be
cleaned with a
soft, dry cloth applying minimal
pressure. As the lens is polished and coated, do
not
use a wet or coarse cloth, detergents, abrasive
substances or solvents to clean it.
When transporting the Prisma we recommend that
you use the carrying case provided. Do not allow the
transformer or cables to move about within the case,
as they may cause damage.
If the hinges loosen with use they can be tightened
with the Allen key provided. To do this, pull off the
caps covering the hinge screws and insert the Allen
key into the screw head. Turn each screw clockwise
about a quarter turn
– do not over-tighten. Replace
the caps. Loosening of the hinges is not covered
under the terms of warranty; it is a user-maintenance
issue.
Only use the transformer supplied with the unit and
inspect the cabling regularly for damage. The
