Preventive Maintenance
The only areas accessible for field service are external. Internal adjustments of the optics require
special tools and must be performed by qualified engineers at the factory.
Do NOT open the stimulator housing for any reason. There are no user-serviceable
parts inside.
User Maintenance
1. Painted external surfaces of the stimulators may be cleaned with a soft cotton cloth or
standard alcohol pads.
2. Avoid touching the large eye lens. Apply lens cover when the instrument is not in use.
If necessary, clean lens with eyeglass cleaning materials and soft cotton or micropore
cloth.
3. Calibration
Perform Grid Calibration and Auto-Calibration at periodic intervals of less than three
months and after updates to the VERIS software. Instructions are found below and in
the VERIS User Manuals.
