6. Other Measurement Modes 6.1 SETUP Mode



1. Features 1. Various Measurements Supported. Not only the usual refractometry and keratometry, but also corneal diameter and base curve of contact lens can be measured with this one instrument. Thus, measurements of eye and prescriptions for glasses and contact lenses can be made more efficiently.



2. Wide Dioptric Measurement Range Because the URK-700 covers a wide measurement range, from -25D to +22D, even an examinee with strong myopia can be measured.



3. More accurate Measurement.



The foggy method of the eye fixation target makes examinee’s eye comfortable and enables to get more accurate measurement data.



4. Easy Connection with other Equipments This instrument is designed to connect other equipments such as VCR or TV monitor.



2. Notes for Using the Instrument



1. Do not hit or drop the instrument. The instrument may be damaged when it receives a strong impact. The impact may cause damage the function of this instrument. Please do handle with care.



2. An exposure to the direct sunlight or too bright indoor lights may



influence on the result of accurate measurement.



3. To connect this with other relevant equipments, consult with the dealer about the way to make it.



4. A sudden heating of the room in cold areas will cause condensation on the protective glass in the monitor screen and on optical parts inside the instrument. In this case, just wait until condensation disappears before performing measurement.



5. Keep the objective glass of the examinee side clean. If it was stained, it may cause on ERROR or inaccurate measurements.



6. In case there is smoke, strange odor or noise on working disconnect the power supply and consult the dealer.



7. Don’t use organic solution such as alcohol, thinner, benzene, etc. to clean the surface of this instrument. It may damage the instrument.



8. When moving this URK-700, fix the stage by using clamping bolt and stage holding knob, always keep power off, and then lift the bottom of the unit with both hands.



9. If you leave URK-700 without using for certain period, disconnect the power supply and protect the unit with dust cover.

4. Practicing by Model Eye Practice measurement by using the Test Model Eye before doing the measurement of patient’s eye.



(1) Turn ON the power Turn ON the power switch on the lower left side. (2)



Set the model eye on Remove the chin rest paper and align the holes on the base of the model eye with the holes on the chin rest. And insert pins.



(3) Release stage lock Fully turn the bolt in the underneath cover in counter clockwise direction. And turn the stage holding bolt in counter clockwise direction to release the stage lock. (4) Adjust height of Test Model Eye. Adjust the height of the chin rest by rotating Height Adjustment knob so that The Test Mode Eye is aligned with the Height Adjustment mark on the headrest. (5) Enter K/R or REF Mode If neither K/R nor REF is displayed on the monitor press MODE button until either one is displayed. (6) Adjust the position and focus on the Model Eye. Looking at the monitor incline the operation joystick toward the Model Eye until a bright dot appears near the inner alignment mark. Place the bright dot in the center of inner alignment mark. Focus on the Model Eye by inclining the operation joystick forward and backward so that KERATO RING image is displayed clearly on the monitor, at the time adjusted the bar would be appeared above the inner alignment mark.
