During Use
WARNING •When moving the refractor head, make sure that there are no obstacles in
its path.
If the arm is swung carelessly, it may bump against someone or something and injury
or malfunction may occur. In addition, the near point rod may topple over and injury
may occur.
CAUTION •Unplug the power cord and contact NIDEK or your authorized distributor if
the internal wires are exposed, the table turns on or off when the power
cord is moved, or the cord and/or plug are not to the touch.
This may result in electric shock or fire.
•Do not look directly into the illumination for the near vision test or VD
check.
The retina of the operator or patient may be damaged.
•Keep the measuring windows free of fingerprints and smudges.
Failure to do so could affect the data accuracy.
•In the event of smoke or strange odors, immediately turn off the device and
disconnect the power plug from the outlet. Once it is determined that the
smoke has stopped, contact NIDEK or your authorized distributor.
Continued use of the device under such abnormal conditions may cause fire or elec-
tric shock.
•When the device is not in use, turn it off and cover it with its dust cover.
If the device is not covered for an extended period, the accumulation of dust may
affect the data accuracy.
•Do not touch the touch-screen panel with anything other than the tip of a
touch-screen pen.
Contact with a hard or sharp object such as a ball point pen may scratch the panel.
In addition, although the tip of a touch-screen pen is covered with resin which is
unlikely to scratch the panel, the panel may be scratched by strongly pressing the pen
against the panel.
Do not touch the panel with fingers. Doing so could decrease the panel sensitivity or
make the panel dirty. It may affect the test accuracy.
•Perform the visual and operation checks before using the device. If any
abnormality is found, do not use the device.
Continued use of the device under such abnormal conditions may affect the data
accuracy. Unexpected malfunction or faulty diagnosis may induce unexpected health
hazards.

1. BEFORE USE
1.1 Outline of the Refractor
The NIDEK REFRACTOR Model RT-5100 is a computerized refractor used for subjective refraction in
connection with the NIDEK AUTO REFRACTOMETER (AR), AUTO REF/KERATOMETER (ARK),
AUTO REF/KER/TONOMETER (RKT), or AUTO LENSMETER (LM).
The RT-5100 includes a refractor head, control box, relay box, and printer.
The relay box is used for connecting not only the other three units but also the auto refractometer or
lensmeter. The control box includes the key panel and display. The display is a touch-screen panel.
The control box not only displays data and is used to perform almost all operations. In addition, the
control box not only operates the refractor head but also the connected chart presenting device. It
allows the refractor and charts to be controlled together.
Normally, the relay box and printer are installed on the system table (not included in the RT-5100
package.)
* In this operator’s manual, the keys on the control box are indicated by key representations such as
or . The touch buttons on the touch panel other than chart buttons are indicated by brack-
ets such as [Div.].
The touch panel chart buttons are indicated by button representations such as .
1.2 Intended Use
Instrument providing means of positioning spherical and cylindrical lenses, prisms and other optical
devices in front of a subject’s eyes for purpose of determining refractive error and binocular functions.
