2. Preparation ■ Using the handy clamp screw When setting the instrument on the adjustable table (such as the double table), clamp the right, left, fore and backward movement of the sliding seat by screwing in the handy clamp screw.
2 - 2 Measuring the Model Eye 1 Insert the model eye’s two pins into the model eye mounting holes in the forehead rest part. 2 Check the VD value on the TV monitor. (120V: 13.75, 230V: 12.0) 3 Using the joystick lever, align the target with the model eye. (For details on the measurement method, refer to P.12 to 27.) 4 Compare the measured values for the model eye with the values (SPH, CYL and R) listed on the label attached to the model eye and check that the difference in values all fall within the following...
2. Preparation 2 - 3 Checking Settings Factory settings are as follows. For details on the meaning of settings or on how to change settings, refer to “5 Making Various Settings (Setup)” (P.29 to 42). Measurement mode setting AUTO Fixation chart brightness setting Patient No.

3 - 2 Continuous Measurement Mode A-C-M 1 Press and set the measurement mode to QUICK 2 Press R–K /1 and select the R–K mode. 3 Measure the patient’s eyes using the same steps 3 through 10 as given in “3-1 Auto Measurement Mode”.
3. Measurement Method 3 - 3 Manual Measurement Mode A-C-M 1 Press and set the measurement mode to QUICK 2 Press R–K /1 and select the R–K mode. 3 Position the measuring head versus the patient’s eye using the same steps 3 through 8 as given in “3-1.
3 - 4 Quick Measurement Mode Quick Measurement Mode with shortened refraction measurement times is useful such as when measurement is difficult due to quick motion of the eye in the case of an infant or nystagmus. Although the refraction measurement time in this mode is reduced to about half of the usual time, fluctuations in measured values may increase greatly.
3. Measurement Method 3 - 5 Printing 1 In Auto Measurement Mode, if the AUTO PRINT setting is set to ON, measurement results are printed automatically after measurements are completed. In Continuous or Manual Measurement Mode, or when the AUTO PRINT setting is set to OFF, press key to obtain a printout.
