V. MAINTENANCE OF THE
OPTEC
®
1000 VISION TESTER
Stereo Optical's OPTEC
®
1000 Vision Tester was designed to
minimize maintenance. It has been engineered and built for a lifetime of
use. The only annual maintenance required is simple and does not
necessitate a service call. There are no moving parts with the
OPTEC
®
1000.
The only components requiring occasional maintenance are:
• EYEPIECE LENSES: The external sides of these lenses need to
be cleaned occasionally (see figure #2). Care should be taken not
to use any abrasive material on these lenses. Use the cleaner
supplied with the vision tester. It is important to dry the lenses with
a soft cotton cloth or tissue.
• CLEANING OF SLIDE: Open the slide cover door and remove
the slide. Use a damp soft cloth or tissue with lens cleaner and
wipe both sides of the slide.
