The RK600 is an advanced electronic refractometer/keratometer which quickly acquires precise data of
the human eye. The information below will assist you in detailing the initial steps to obtain optimum
performance of this instrument.
Perform the following steps after removing the RK600 from its shipping container.
1. Install the unit in its permanent location and then ensure that the Travel Lock has been disengaged.
2. Remove the plastic protector that is installed onto the LCD Screen to prevent scratches and contami-
nants on the screen.
3. Install an adequate supply of Chin Rest Pads onto the Chin Rest and secure them with the Chin Rest
Pins. Refer to Figure T1.
4. Install the Printer Paper as indicated in the Maintenance section of this manual.

R/K Measurement Mode
Measurement Modes
The RK600 has six measurement modes:
R/K Refraction and keratometric data
R Refraction only data
K Keratometric only data
P.K. Peripheral keratometric data.
IOL R/K Refraction and keratometric data, utilizing IOL ltering
IOL R Refraction only data, utilizing IOL ltering
Note: When power is applied to the RK600, the instrument automatically
displays the last used measurement mode.
Note: When acquiring IOL patient data, it is recommended that the IOL option
be used. Using IOL lter options for non-IOL patients may cause
occasional measurement diculty for patients with reduced pupil
diameters.
The following information describes the correct method for acquiring refractor
and keratometer measurements using the RK600.
1. Ask the patient to place their chin on the Chin Rest and then move their
head forward until their forehead is placed against the Headrest.
2. Adjust the Vertical Alignment Knob and move the Joystick until the patient
can view the xation target (the house) with their right eye.
3. Twist the Joystick until the pupil is vertically centered on the LCD Screen.
4. Move the Joystick left, right, in and out until the circle is in focus and the
PLUS icon (+) is in the center of the circle.
• If the instrument is set for the AUTO mode, the measurements will
automatically be acquired when alignment is achieved.
• If the instrument is set for the MANUAL mode, the Fire Button must be
depressed to acquire a measurement when alignment is achieved.
5. Repeat the above steps for the left eye.
6. Press the PRINT button if a print-out of the measurements is desired .

Peripheral measurements are measurements of the eye which are taken at its
center and four equidistant points around the eye to determine the curvature of
the cornea. The peripheral section of this instrument acquires ve measurements;
one at the center, and four measurements (superior, temporal, inferior, and nasal)
which are equidistant from the center of the eye and each other. To acquire a
peripheral measurement, the patient xates on the peripheral diode and the
operator aligns the instrument to the center of the target.
Perform the following steps to take a peripheral measurement:
1. Press the button below the MODE button until the PERIPHERAL icon is shown for the
peripheral mode. In this mode, the peripheral icon is displayed on the LCD and the ac-
tive position is indicated by the blinking segment.
2. The middle segment is the rst blinking segment. Align the instrument to the right
eye and press the FIRE button (on top of the Joystick) when the PLUS (+) icon is in
focus (IN and OUT distance) and is at the center of the circle on the Operator Screen.
3. Instruct the patient to xate on the red LED. When the patient is ready, align the PLUS
(+) icon so that it is in focus (IN and OUT distance) and is at the center of the circle on
the Operator Screen, and then press the FIRE button.
Note: The red LED that the patient observes is opposite in position to the blinking
segment of the peripheral icon. The blinking segment relates to the position on
the eye that is measured (when the patient looks down, the area above the center
of the eye is measured).
4. Repeat the above step until all four peripheral measurements are acquired.
5. Repeat the above steps for the other (left) eye.
The denitions of the peripheral data categories on the screen (or print-out) are
as follows:
C = Measurement at the center of the eye
T = Measurement at 30 degrees from the center of the eye on temporal side of the
eye.
N = Measurement at 30 degrees from the center of the eye on nasal side of the eye.
S = Measurement at 30 degrees from the center of the eye on superior side of the eye.
I = Measurement at 30 degrees from the center of the eye on inferior side of the eye.
e = Eccentricity of the eye, average total.
H = Eccentricity of the eye in the horizontal meridian.
V = Eccentricity of the eye in the vertical meridian.

The print function in this instrument has three options.
• Automatic mode - This option automatically prints out the data after all
measurements are taken on both the right and left sides.
• Manual mode - This option prints out the data only when the print button is
pressed.
• Additionally, the printer can be set to the OFF mode. In this mode the
printer does not print even if the print button is pressed, and the data is sent
to the serial port instead of the printer.

Introduction
The RK600 requires very little routine maintenance due to its advanced design.
For instance, there are no bulbs or lamps to change.
If you have questions regarding maintenance, contact your local distributor, or
our Customer Service Department directly at [phone].
Cleaning
CAUTION: DO NOT USE ALCOHOL OR ANY SOLVENTS ON ANY EXTERNAL SURFACE
OF THE INS TR UMENT OR DAMAGE TO T HE PAINTED OR COATED
SURFACE MAY OCCUR.
Joystick
Clean external surfaces of the Joystick using a clean, soft cloth that is only
lightly dampened with a mild detergent solution (1 cc of liquid dish soap to
one liter of clean ltered water (e.g., ltered below 5 microns)).
Operator Display
Clean the Operator Display using a clean, soft cloth that is only lightly
dampened with a mild detergent solution (1 cc of liquid dish soap to one liter
of clean ltered water (e.g., ltered below 5 microns).
Patient Mire Window
Clean the Patient Mire Window using a clean, soft cloth that is only lightly
dampened with a mild detergent solution (1 cc of liquid dish soap to one liter
of clean ltered water (e.g., ltered below 5 microns).
Instrument Covers
Clean external surfaces of Instrument Covers using a clean, soft cloth that is
only lightly dampened with a mild detergent solution (1 cc of liquid dish soap
to one liter of clean ltered water (e.g., ltered below 5 microns).
Replacement Chin Rest Pads
For hygienic reasons, replaceable Chin Rest Pads are included with this
instrument. After a patient is measured, it is recommended by Reichert that the
top Chin Rest Pad be discarded so that hygienic conditions are maintained.
Measurement Verication
Included with this instrument is a Model Eye that may be used to simulate a
measurement on a patient. Use this Model Eye when a performance check of
the unit is desired. To acquire a measurement using this eye, remove the Chin
Rest Pads and install the Model Eye onto the Chin Rest. Measurements acquired
using this eye must be within the tolerances indicated on the Model Eye. If the
measurements are not within tolerance, check the mounting and position of the
Model Eye then acquire another measurement. If the measurement is still not
within tolerance, contact your authorized Reichert distributor, or the Reichert
Customer Service Department as indicated in the Introduction section of this
manual.
Fuses
Fuses are located next to the power inlet (Refer to page 8). Only replace with
fuses recommended by Reichert.
