i
To the User of the RC-5000 AUTO REFKERATOMETER
The RC-5000 AUTO REFKERATOMETER is especially designed for measuring eye's re-
fractive power and corneal curvature.
The RC-5000 provides the additional functions of PD, corneal diameter, pupillary diameter,
and CL base curve measurements. Since, however, the measurement quality of these func-
tions is not guaranteed, the exclusive equipment designed for respective measurements
should be used.

1. PRIOR TO USE
Please read this Operation Manual throughout before
operating this instrument.
Do not use any procedures other than specified in this
Manual.
1.1 SAFETY PRECAUTIONS


 The following precautions shall be given for installing this
instrument.
- Do not install the instrument in a place where any chemicals are
stored or any gas is generated, or it may otherwise be inflamed to
catch a fire, if such chemicals or gas is spilled or evaporates into
the inside of the instrument.
- Do not lift the instrument by holding the Chin Rest or the Head
Rest, which may otherwise cause the instrument to slip to fall
down and possibly harm you.
- Make sure that the frequency, voltage, allowable current (or
consumption power) of your power source used for the
instrument are proper. The wrong power, if used, may cause
inflammation or electric shock.
- Properly connect the grounding wire, which may otherwise cause
struck by electricity.
- Do not place a heavy object over the power cord nor squeeze it
with undue force, or it may cause inflammation or electric shock.
- Be sure to securely connect the power cord with the instrument.
The power cord, if improperly connected in contact failure, with
the metallic part, or with the exposed plug terminal covered with
dust, may cause inflammation or electric shock.
- Do not connect the instrument to any equipment of which data
transfer code is different from that for this instrument. Which may
cause inflammation or struck by electricity. In case of connecting
this instrument to the communication connector, be sure to
consult with Tomey Corporation.
1.1 SAFETY PRECAUTIONS

1-2
- Install the instrument in a place where it is not exposed to water
and / or chemicals. In case Water and / or chemicals enter into
instrument, it may cause struck by electricity or malfunction.
- Install the instrument in a place where it is fear free of adverse
influences by direct sunbeams, high temperature, high moisture,
dust, salt, sulfur contained air, which may otherwise cause the
instrument with malfunction or erroneous operation.
- Install the instrument in a stable place where it is free of
inclination, vibration and/or shocks, which may cause incorrect
measurement, tilting, or falling, possibly resulting in inflammation
or physical injury.


 Sufficient care shall be taken on the following items while
operating the instrument.
- In the event the instrument causes smokes, odors, or abnormal
noises, immediately turn the power off, disconnect the power
plug from the receptacle, and then report so to your local
distributor, representative, or Tomey Corporation.
- Pay attention and carefully to the position of Patient's face and
hand or fingers ,When operating Measurement Head and Chin
rest. It may cause physical injury depend on movement of
Measurement Head and Chin rest.
- Advise the Patient not to place his hand and fingers in the under
space of the Measurement Head or below Chin rest, which may
otherwise cause his hand and fingers to be pinched and harmed.
- Do not either lean or compress the instrument, which may
otherwise cause its fall or malfunction, or personal injuries.
- Do not place or leave any liquid contained bin or container on the
instrument, which may cause struck by electricity or
malfunctions.
- Do not touch the Printer paper cutter with your fingers, which may
cut yourself.
- Before measuring the next Patient, remove the top sheet of
paper from the Chin Rest and clean the Head Rest with clean
cloth. Also, clean the Head Rest and the Chin Rest with
sterilization alcohol-soaked cloth for sterilization.
1.1 SAFETY PRECAUTIONS

1-3


 Care shall be taken on the following items, after using the
instrument.
- Do not use organic solvents, such as thinner, benzene, and
acetone, for cleaning the instrument, which may cause
inflammation or struck by electricity.
- Do not apply an undue force to the power cord when
disconnecting from the receptacle, but hold the plug unit instead.
If the cord is forcedly pulled, the core wire inside of the cord may
be broken, causing struck by electricity or inflammation.
If the instrument is suspended for a long period of time,
disconnect the power cord from the receptacle for safety.


 When the instrument is malfunctioned, discontinue its
operation and display such failure. Then, ask your distributor
for repair.
- Do not remodel or modify this instrument, which may disorder the
functions and/or cause of struck by electricity or malfunctions. It
should also be noted that the instrument provides the high
voltage generating source inside its unit which may induce struck
by electricity, if touched, causing fatal injuries or death to the
worst.
- Replacement of the fuse shall be performed with the power cord
as being disconnected from the receptacle, which may otherwise
induce struck by electricity, serious injury or death to the worst.
- If the instrument has not been used for a long period of time,
make sure before reuse that it works properly and safely. As for
the procedure of its confirmation, see "5.4 ROUTINE
MAINTENANCE" of this Manual.

1.2 UNPACKING
After unpacking, make sure that you have received the fol-
lowing items without damages. In the event that any item is
found missing or damaged, contact your local distributor.
The packing box and the cushion materials should be
kept, since they may be necessary, if the instrument is
moved or transported to other places.

1.4 OUTLINE OF OPERATIONS
The Auto Refkeratometer, RC-5000, is an objective refractive power
measuring instrument which provides the ophthalmometry function to
measure corneal curvature.
The Patient places his chin on the Chin Rest and looks the fixation target
through the measurement window. The examiner adjusts the focusing di-
rection by moving the Joystick up/down/left/right. After this adjustment
above, press the measurement button to start measurement.
This instrument also provides the Auto Alignment mechanism for auto-
matic alignment; therefore, easy measurement operation is obtainable. In
addition, the instrument provides the Auto Shot function which automati-
cally starts measurement when the instrument enters in the area of mea-
surement. Once automatic measurement starts, the infrared light is pro-
jected for measurement to analyze the refractive power and the corneal
curvature of the eye.
Measurement data is printed out by pressing the Print button.
