INTRODUCTION Thank you for purchasing the Auto Refractometer RM-8800, Auto Kerato-Refractometer KR-8800.

This instrument is used to measure the spherical refractive power, the cylindrical refractive power, the direction of astigmatic axis, the radius of curvature, the direction of principal meridian and the corneal refractory power. This instrument has the following features: • It measures the refractory power of the eye as well as the corneal curvature by means of simple operations. • The minimum measurable pupil diameter is now smaller, thus the measuring range is extended. • The “auto start” function facilitates quick measurements under optimal conditions.

This Instruction Manual gives a summary of the basic operations, troubleshooting, check-ups, maintenance and cleaning of the Auto Refractometer RM-8800 and Auto Kerato-Refractometer KR-8800. To get the most out of the instrument, read Safety Displays and Safety Cautions. Keep this Manual at hand for future reference.

PRECAUTIONS • As this product is a precision instrument, always keep it in a normally controlled living environment, within a temperature range of 10 - 40°C, with humidity levels between 30 - 75% and an atmospheric pressure range of 700hPa - 1, 060hPa. Keep the instrument out of direct sunlight. • To ensure smooth operation, install the instrument on a level floor which is free of vibrations. Do not place items on the instrument. • Connect all cables properly before use. • Use the power at the rated voltage. • When not in use, switch off the power source and replace the measuring lens cap and dust cover. • For accurate measurement results, make sure the examination window is clean and free of fingerprints, spots and dust.

SAFETY CAUTIONS WARNINGS Icon

Meaning

Page

Do not attempt to overhaul, rebuild or repair: this may result in an electric shock. Contact your dealer for repairs.

Do not remove covers from bottom and top surfaces, monitor, measuring unit, etc, as this may result in an electric shock.

Do not allow water or other foreign matter to enter the instrument: this could result in a shock.

––

Do not place a cup with water/fluid on the instrument: if knocked over, this could result in fire or an electric shock.

––

Do not insert metal objects in the vent holes or gaps, or keep them inside the machine body: this could result in an electric shock.

––

Make sure the power cable is unplugged before removing the fuse lid, in order to avoid electric shock during fuse change. Also, do not plug in the power cable while the fuse box is still open.

Always use the attached fuse (T-3A, 250V). Using any other type may cause problems and even result in a fire.

Should any anomaly occur, such as smoke, immediately switch OFF the power source and unplug the power cable. Continued use while ignoring the condition may result in a fire. Ask your dealer for repair.

SAFETY CAUTIONS CAUTIONS Icon

Meaning Before moving the instrument, fasten the clamping knob below to ensure immobility. Neglecting to do this may result in injury from falling parts. The instrument should be moved by two people, holding it at the bottom. One person lifting the instrument may result in backache or injury from falling parts. Holding any other area than the bottom of the instrument may result in pinched fingers or injury from falling parts, as well as damage to the instrument.

Page

Do not install the instrument on slopes or unstable floors, as the instrument body or other parts may fall, resulting in injury.

Do not handle the power plug with wet fingers, as it may give an electric shock.

Do not insert fingers under the chinrest as this could result in injury. *Be sure to tell this to the patient.

This instrument has been tested (with 120V/230V) and found to comply with IEC60601-1-2: 2001. This instrument radiates radio frequency energy within the required standards, and may affect other devices in the vicinity. If you have discovered that turning the instrument on/off affects other devices, we recommend you change its position, keep a proper distance from other devices, or change the outlet. Please consult the dealer from whom you purchased the equipment for any questions.

The Ι mark is displayed at IOL mode. If the reliability is low and values of C and A cannot be determined, ∗∗ marks are given to the pertaining columns. Typical value of left eye PD (pupil distance)

Reliability factor

When measurement is done under the IOL mode, a reliability factor is printed out following the Ι mark. The reliability factor is formed with integers 1 to 9 in an increasing order of reliability. Additionally, if the reliability is high enough, the reliability factor is not shown in the printout.
