7.4 Cleaning the Optical Surfaces
Always use a lint-free lens cloth to clean the optical surfaces. Ensure
the cloth is kept clean. A dirty lens cloth can scratch the optical
surface and cause permanent damage to the instrument.
Replacement lens cloths can be purchased from ENVEA.
Ordinary tissues and dusters are not suitable and can scratch
the delicate optical surfaces.
Do not attempt to move the zero reflector by hand. The precision
gearbox will be irreparably damaged.
