Never insert your fingers under the measuring head. ∗ Inform the patient of this, too. Careless insertion of fingers may cause injury by pinching.

30

Never insert your fingers under the measuring head. ∗ Inform the patient of this, too. Careless insertion of fingers may cause injury by pinching.

34

Do not use or apply any spray-typed cleaner near the instrument. If a drop of cleaner remains inside the measuring nozzle, the patient’s eye may be injured during measurement.

56

Before carrying the instrument, be sure to affix it firmly by turning the fixing screw at the base. If the instrument is moved with the screw loosened, it may result in damage to the instrument.

13

When moving the instrument, be sure to hold it at the bottom surface with two people. Carrying by one person may cause back injury or injury by falling parts. Also, holding areas other than the bottom surface may cause pinching fingers between parts and injury by falling parts as well as damage to the instrument.

13

Before measuring, set the safety stopper. If the safety stopper is not set, it may cause injury to the eye that comes in contact with the measuring window glass. Set the safety stopper separately for the right and left eyes.

31

When setting the safety stopper, do it from the instrument side (safety stopper knob side). Setting from another position does not easily allow you to check the positions of the measuring window glass and the patient’s eye and may cause injury to the eye that comes in contact with the measuring window glass.

31

To clean the measuring window glass and the window glass inside the measuring nozzle, use ethanol. Using other chemicals may cause damage to the patient's eye during measurement.
