1 War ning War ning Caution Caution INTRODUCTION If the instrument should be operated wrongly, there may incur a risk of causing death or serious injury. If the instrument should be operated wrongly, there may result in a bodily injury (not so serious as to cause death) ✽ 1 or damage to property ✽ 2 .
2 War ning War ning If any abnormal smell or sound, or overheating or smoke should be detected, be sure to turn OFF the main power immediately and then unplug the instrument from the power outlet. Continued use of the instrument may cause the instrument to malfunction or cause a fire.
3 Description of Labels and Symbols Location of Cautionary Marking Before replacing fuse, be sure to turn OFF the main power and unplug the instrument. Removing the fuse holder cover without unplugging the instrument may cause electrical shock. Type B applied parts (degree of protection of applied part against electric shock).
4 • Handle the instrument with care, and do not ap- ply strong shock to it. Also, do not leave any objects on the instru- ment. • Always cover the system when not in use in or- der to protect its components. • Avoid high temperature and humidity, direct sunlight, and dust when shipping, installing, and storing the instrument.
5 1. Instrument should be operated only by qualified personnel. 2. The following precautions must be observed when installing the instrument: (1) Install at a location free of moisture.

15 ■ 3-1 Installation Place the device on a motorized table (optional accessory). Make sure that POWER Switch shown in Fig. 1 is at OFF position (O). Connect the power cable to the power supply inlet and connect the other end of the cable to a nearby wall outlet.
16 ■ 4-4 Frontal view switch Use this switch to c h ange from fine adjustment (Diagonal alignment screen) to coarse adjustment (Frontal view alignment screen) or return to fine adjustment (Diagonal alignment screen) from post-measurement (Measurements graph screen) (Fig.
17 Stained lens may affect measurements. It is recommended to calibrate regularly in order to obtain accurate measurements. A message will appear during device start-up if the device had no calibration done for more than a month. Calibrate the device as soon as possible when the message appears.
18 Close the light shade as shown in Fig. 9 for calibration, BG check, and measurement. 5 Fig. 5 is displayed when calibration is completed. 6 Slide the protective cap back into the original position, and turn Calibrator counterclockwise to MEASUREMENT position (Fig.
19 2 As shown in Fig. 4, move the luminous dot into “ ” mark and adjust the position of Main unit or Measurement unit to reduce the size of the luminous dot as small as possible.
20 Points for alignment 1. Measurement window must be between the left and right laser beams. 2. Measurement window must be located below the Spot light.
21 BG level indicator BG check finds out the uniformity of background lights by determining the back- ground lights around Measurement window. Level of the uniformity appears in Measurement window shown in the display. This is what we call “BG level indi- cator”.
22 ● Waveform evaluation Flare is compared with |BG1 - BG2 | per measurement. (SIG – BBG ✽ ) - |BG1 - BG2 | > 0 is acceptable and no message is displayed. (SIG – BBG ✽ ) - |BG1 - BG2 | 0 is unacceptable and the message “ Inappropriate Data Form.

24 ■ 7-4 Recommended procedures when BG check obtains no good result Reading on the eye. BG check may result in good without using the alignment mark (Fig. 4). Important point is to align the device so that no iris image or reflected glare comes into Measurement window (see ■ 6-4 Diagonal view alignment).
25 ■ 7-5 Recommended procedures when measured waveforms are offset to left or right You may encounter waveform offset to the left as shown in Fig. 6 when attempting a measurement at an excessively lower part of the anterior chamber. You can not obtain a correct flare value in this condition.
