INTRODUCTION

RM

Thank you for purchasing the Auto Refractometer

This instrument is used to measure the spherical refractive-power,cylindrical refractive power, the
direction of astigmatic axis, the radius of curvature, the direction of principal meridian and the cor­neal refractory power.

This instrument features the following:

• Measures the refractory power of eye and the corneal curvature with simple operations.

• The minimum measurable pupil diameter is now smaller and thus the measuring range is
extended.

• The auto start function facilitates quick measurements under the optimal condition.

This Instruction Manual covers an overview of the basic operation, troubleshooting, checking,
maintenance and cleaning of the Auto Refractometer

KR-8800.
To get the best use of the instrument, read Safety Displays and Safety Cautions.
Keep this Manual at hand for future reference.

PRECAUTIONS

• Since this product is a precision instrument, always use and keep it in a normally controlled liv­ing environment, within a temperature range of 10-40°C, humidity levels between 30-75% and
an atmospheric pressure range of 700hPa-1,060hPa.
The instrument should also be placed away from direct sunlight.

• To ensure smooth operation, install the instrument on a level floor free of vibrations. Also, do
not put things on the instrument.

• Connect all cables properly before using.

• Use the power at a rated voltage.

• When not in use, switch off the power source and apply the measuring lens cap and dust cover .

• For accurate measurement results, take care to keep the examination window clean and free of
fingerprints, spots and dust.

SAFETY CAUTIONS

WARNINGS

Icon Meaning Page

To avoid electric shocks, do not attempt overhauling, rebuilding or
repairs. Ask your dealer for repair.

To avoid electric shocks, do not remov e co vers from bottom and top
surfaces, monitor, measuring unit, etc.

To prevent shock hazard, do not allow water or other foreign matter
to enter the instrument.

To avoid fire and electric shocks in case of tumbling, do not place a
cup or vessel containing water/fluid on the instrument.

To avoid electric shocks, do not insert objects metals through vent
holes or gaps or contain them inside the machine body.

To avoid electric shocks during fuse change, be sure to unplug the
power cable before removing the fuse lid. Also, do not plug the
power cable leaving the fuse box open.

Always use the attached fuse (T-3A,250V). Using any other type
may cause troubles and fire.

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

SAFETY CAUTIONS

CAUTIONS

Icon Meaning Page

Before moving the instrument, fasten the clamping knob at the bot­tom surface to stop movements. Negligence of this may cause
injury by falling parts.

When moving the instrument, be sure to hold it at the bottom sur­face with two persons. Carrying by one person may cause a back­ache or injury by falling parts. Also, holding area other than the
bottom surface may cause pinching fingers between parts and
injury by falling parts as well as damage to the instrument.

19

19

To prevent injury due to tumbling of the instrument body and falling
parts, avoid a slope and unstable floor for installation.

To avoid electric shocks, do not handle the power plug with
wet fingers.

To avoid injury, do not insert fingers under the chinrest.
*Be sure to instruct the patient about this.

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