Setting the Safety Stopper
CAUTION
CAUTION
Before measuring, set the safety stopper. If the safety stopper is not set, it may cause injury to the eye that co- mes in contact with the measuring window glass. Set the safety stopper separately for the right and left eyes.
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.
1 Hold the control lever and pull the machine body towards the operator.
2 Turn the control lever and adjust the height of the measuring nozzle to the center of the patient's cornea.
3 While holding the safety stopper knob in a pressed position, hold the control lever and slowly push out the machine body.
