CAUTION 1Intended Use
Only use the Auto Refract-keratometer Speedy-K for measuring the refractive power of the
eye and curvature of the cornea.
Do not use this instrument for any other purpose.
CAUTION 2Do Not Disassemble
Disassembling this instrument may lead to electric shock and/or malfunction of the instrument.
Never disassemble this instrument.
CAUTION 3During Measurement Operations
•Particularly in the case of little children, take care that patients do not put their fingers in
the moving parts of this instrument.
•Take care that the measuring head does not strike the patient’s nose. (When moving the
measuring head toward the patient or toward the patient’s left or right eye.)

CAUTION 4During Installation and Transportation
Be absolutely sure to support the instrument as shown in the figure at left during transportation.
Do not carry the instrument by the forehead rest, measuring head or joystick lever.
•Recommended operational conditions are an air pressure of 800 to 1060 hPa, a temperature
of approximately 10C to 35C, and a relative humidity of 30 to 70%.
•Although the instrument is dust-proof, do not use it in a room where there is a lot of dust or dirt.
•The best place for installation is a dimly lit room. Do not face the patient side of the
instrument toward a bright window or source of light.
•Although this instrument conforms to EMC standards (IEC60601-1-2:2001), it does emit
a weak electromagnetic signal. If use of this instrument affects other equipment such as
televisions or radios, separate it from the affected devices or change the direction it faces.
•Since this instrument is not water-proof in construction, never take it into locations where
liquids such as rain or beverages may get inside.
•If condensation (dew) forms, do not use the instrument until the condensation disappears.
•The environmental requirements for transport and storage are -40℃ to +70℃ in temperature
and 10% to 95% in humidity.
CAUTION 5Other Notes on Handling
•Always use a specified power cord that is rated for the voltage used in your area and that
has been approved under local safety standards.
Using the wrong power cord could result in damage or fire.
For 100 V – 120 V area : UL listed, detachable cord set, 3 conductor grounding type SVT,
No. 18 AWG rated at 125 V, 7 A minimum.
For 230 V area : 3-pole power supply cord set, which must be approved according
to EU/EN standards.
•Do not scratch, break or alter the power cord or overly bend, pull, twist or bundle it. Also,
placing heavy objects on the power cord or subjecting it to heat may cause it to break,
resulting in fire or electric shock. If the power cord becomes damaged, be sure to replace
it with a new cord.
•When transporting this instrument, always be sure to first tighten its securing screws. ( P.8)

OFF
•If there is any dust on the power plug blades or the surface they connect to, pull out the
power plug and remove the dust. The dust or grime can make the power plug and AC
power outlet to be out of contact and may result in fire.
•This refractometer is a precision optical instrument containing many electronic components.
Be sure to handle it carefully and do not subject it to strong physical shock.
CAUTION 6Maintenance and Storage
•The specified transportation and storage environment is a temperature of –10°C to 45°C
and relative humidity of 20 to 85%.
•When replacing a fuse, be sure to turn off the power switch and pull out the power cord.
Be sure to use only a fuse of the specified rating. Electric shock or fire may occur if a fuse
other than of the specified rating is used. (Specified fuse: time lag fuse T1AL/250V,
SCHURTER 0034.3117) (→ P.45)
•Measurement results are adversely affected if
the measuring window glass surface becomes
soiled with grease from the patient’s nose,
fingerprints or dust. Be sure to always keep
the measurement window glass clean.
When cleaning the measurement window glass, take care not to scratch or break it. (→P.37)
•When finished using the instrument, turn off
the power switch and cover it with its plastic
cover.
•The internal battery
The instrument includes a primary lithium battery as the power source for the clock function
and all setting functions stored in memory. If the battery goes out, the time and date
printed on the measurement printout will be wrong. Also, settings will not be stored in
memory and default settings will be restored every time the power is turned off. Contact
your nearest Righton representative when replacing batteries.
•Disposing of the unit
If you dispose of the unit, be sure to follow the local regulations regarding the disposal of
products containing lithium batteries.
