11.5 Periodica l Inspection and Maintenance
To prevent malfunction and accidents and maintain the performance and reliability of the product, it is
recommended to request your distributor for the periodical inspection and maintenance once a year.
The periodical inspection and maintenance include inspection of the function and performance of the
product, and cleaning, adjustment and replacement of consumable parts if necessary.
Note for setting of model eye
Remove a contact lens holder cap and set a model eye, checking it is not inclined in any
directions.
When the model eye is inclined, CYL value can not be correctly measured.
Set the model eye at the position where an alignment mark is located inside a reticle
mark and good focusing is achieved.
When conditions above have been satisfied, proceed to measurement.
