SAFETY INFORMATION Accessory equipment connected to the analog and digital interfaces must be certificated according to the respective IEC standards (e.g. IEC 60950-1 for data processing equipment and IEC 60601-1 for medical equipment). Furthermore all configurations shall comply with the system standard EN 60601-1:2006, Clause 16. Everybody who connects additional equipment to the signal input part or signal output part configures a medical system, and is therefore responsible that the system complies with the requirements of the system standard IEC 60601-1:2005, Clause 16.

Wide Dioptric Measurement Range Because the PRK-7000 covers a wide measurement range, from –25D to +22D, even an examinee with strong myopia can be measured. More Accurate Measurement You can measure more accurately because foggy method of the eye fixation target makes the examinee’s eye comfortable.
Don’t use organic solution such as alcohol, thinner, benzene, etc. to clean the surface of this instrument. It may damage the instrument. When moving this PRK-7000, fix the stage by using stage holding knob, always check if the power supply is off, and then lift the bottom of the unit with both hands.
