The Optec
5000G
INT
Vision Tester is designed to minimize maintenance. All bearings and
internal mechanisms have been sealed at the factory. It has been engineered and built for a
lifetime of use
. Th
e only annual maintenance required is simple and does not necessitate a
service call. The only components requiring occasional maintenance are:
Eyepiece Lenses:
The external side of these lenses needs to be cleaned occasionally. Care
should be taken not to use any abrasive material on these lenses. Use the cleaner supplied with
the Vision Tester, or plain soap and water can be substituted. It is important to dry the lenses
with a soft, lint-free cloth.
Cleaning of Slides:
Open the rear door. Use a damp, soft, lint free cloth with lens cleaner and
wipe the slide. Turn the dial and go on to the next slide repeating the same procedure. Note:
Always unplug the tester before opening the back door and accessing the slides.
Replacement of the Slides:
The slide drum assembly holds up to 12 slides and can be easily
accessed through the rear door
. T
o replace a slide, rotate the dial until the number of the slide to
be removed is under the YELLOW indicator. Open rear door, remove slide on top of drum by
rotating clips toward each other until they clear the slide. Remove unwanted slide. Insert new
with label showing and arrow pointing away from you; return spring clips to their former positions
to secure slide. Close the instrument door and you are again ready for operation.
Control Panel Removal:
The panel is designed with reliable solid state components. The
modular design allows quick segmentation from the rest of the instrument.
Exterior:
The plastic, of which the instrument body and base are made, is similar to your
telephone and can be cleaned in the same manner. Use damp, clean cloth and a mild detergent.
A dust cover is provided for dust protection and to discourage tampering when instrument is not
in use. An eight-foot power cord can be disconnected to discourage tampering as well.
Inside Mirror:
Behind the rear door you will find a front-surface mirror. Handle the mirror with
care and avoid placing fingers on its surface. We recommend using the cleaner supplied with the
instrument along with a damp, soft, lint-free cloth. DO NOT TAMPER WITH THE THREE
SCREWS SURROUNDING THE MIRROR. The mirror has been carefully aligned to achieve
precise light reflections and any tampering will require factory adjustment.
