GENERAL SAFETY INFORMATION
CONTRAINDICATIONS•PROHIBITION
Ensuring the Safety of Patients and Operators
To prevent corneal damage, do not measure a patient with corneal disease or one who's had corneal surgery.
To prevent corneal damage, do not measure a patient wearing a contact lens.
Tell the patient to remove the contact lens.
WARNINGS
Ensuring the Safety of Patients and Operators
When operating the instrument, do not touch the patient's eye or nose.
Preventing Electric Shocks and Fires
To avoid fire and electric shock, install the instrument in a dry place free of water and other liquids.
To avoid fire and electric shock, do not put cups or other containers with liquids near the instrument.
To avoid electric shocks, do not insert metal objects into the instrument body through the vent holes or gaps.
To avoid fire in the event of an instrument malfunction, immediately turn OFF the power switch " " and discon-
nect the power plug from the outlet if you see smoke coming from the instrument, etc. Don't install the instrument
where it is difficult to disconnect the power plug from the outlet. Ask your dealer for service.

CAUTIONS
Important caution
The following patients need extra attention.
• Patients with infectious disease such as Keratoconjunctivitis Epidemica
Ensuring the Safety of Patients and Operators
To avoid injury when operating the up/down button for the chinrest, be careful not to catch the patient's fingers.
The light emitted from this instrument involves potential risk; the longer the irradiation time, the more risk of dam-
age to the eye.
When the instrument operates with the maximum light volume, exposure for more than 2 hours will exceed the
safety guideline.
During alignment operation, please pay attention so that a patient's face does not move.
If the face moves, there is a danger that the main body will touch the patient's face.
When operating the instrument use much care so that operator's finger or hand is not pinched between the
reverse side of forehead rest, an measuring head and an ocular pressure measurement window. Or the operator
may be injured.
Preventing Electric Shocks and Fires
To avoid injury by electric shock, do not open the cover. For repair, call your service engineer.
To avoid injury by electric shock when changing the fuse, turn off the power supply and pull out the power cable.
Use the rated fuse.
Electromagnetic Compatibility (EMC)
This instrument has been tested (with 100/120/230V) and found to comply with IEC60601-1-2:Ed.3.0:2007. This
instrument radiates radio frequency energy within standard and may affect other devices in the 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 plug it into a different outlet. Please consult your authorized dealer
if you have any additional questions.

OPERATION METHOD OF CONTROL PANEL
The control panel is designed as a touch panel for performing various operations and settings. It dis-
plays images and shows information, including set conditions and measurement results.
CONTROL PANEL COMPONENTS (IN REF/KRT MEASUREMENT MODE)
ID button.................................................Input the patient ID (up to 13 characters) and operator ID (up
to 13 characters). However, if no patient ID is inputted, the
patient No. of each patient is allocated automatically.
As for an operator ID, the input column may not be displayed
by setup. (See page 91)
Measurement mode button......................Selects a measurement mode from REF (Measurement of
Spherical refractive power, Cylindrical refractive power and
Direction of astigmatic axis), KRT (Measurement of Cornea
curvature radius, Direction of corneal astigmatic axis and
Corneal refractive power) and R/K (REF/KRT continuous
measurement)
NOTE • The control panel is a touch panel. Do not use any sharp tools; e.g. ball
point pen.
• Do not touch two points on a control panel simultaneously.

COMPONENTS
CONTROL PANEL COMPONENTS (IN TONO/PACHO MEASUREMENT MODE)
ID button...............................................Input the patient ID (up to 13 characters) and operator ID (up
to 13 characters). However, if no patient ID is inputted, the
patient No. of each patient is allocated automatically.
As for an operator ID, the input column may not be displayed
by setup. (See page 91)
Measurement mode button.......................Selects a measurement mode from TONO (Ocular pressure
measurement) and T/P. (Ocular pressure and Cornea thick-
ness measurements.)
R button/L button.............................Selects the right/left eye. By tapping the button, the main
body moves to the selected direction. The selected button is
framed in orange. The layout where the R/L button is dis-
played reverses according to the position of the control
panel.
Up/down button for chinrest............Moves the chinrest up/down.
Air check/End button.................................Displayed under Auto mode: Selects Air check or End opera-
tion. Air check operation checks that the measurement sys-
tem of the instrument operates properly. End operation is to
move the chinrest and measuring head to the measurement
last position.

COMPONENTS
Zoom button....................................Displayed under Manual mode: Enlarges the patient eye dis-
play.
Measuring head ..............................Moves the measuring head closer to/away from the patient's
forward/backward button eye. The direction of movement is reversed according to the
position of the control panel.
Start button.............................................Starts measurement.
Auto/Manual button .........................Switches between Auto mode and Manual mode.
If "A" is displayed on the control panel it is in Auto mode, if
"M" is displayed it is in Manual mode.
The name of the selected mode (Auto/Manual) is displayed
on the control panel.
MODE button........................................Selects R/K, T/P and R/K→T/P measurement mode or set-
ting up screen.
FUNCTION BUTTON

IOL button ...............................................If alignment does not work with a patient who as an IOL, tap-
ping this button may allow the measurement. When the but-
ton is selected, "IOL" is displayed on the control panel and
the selected button is framed in orange.
Sets focusing for IOL and LED brightness for IOL. Refer to
"OPTIONAL OPERATIONS" on page 57.
30/60 button ............................................Switches between 1-30mmHg range and 1-60mmHg range.

COMPONENTS
Count change button...............................Switches between "Multi" and "1x" in Auto mode.
Multi:takes the number of measurements setup by the
user
1x: measurement once (Before shipment, the default
setting is "1x")
When "R/L move" is set to "Full Auto" or "Auto(RL)", after
measuring the first eye, the main body automatically moves
to the settings for the other eye.
All data button .........................................Displays all measurement data on the screen.
Print out button...............................Prints measurement results. Tap the button when no mea-
surement data is present to feed the paper.
All clear button....................................Clears all measurement data.
Safety stopper button..............................Switches to the setting screen of the nozzle limit position to
prevent the measuring window glass from hitting the patient’s
eye during the measurement.
Alignment stop button......................Displayed during a measurement, the alignment operation is
stopped and the measuring head moves backward.

NOTE
• The reliability factor is defined with integers 1 to 9 in increasing order of
reliability.
• Additionally, if the reliability is high enough, the reliability factor is not
shown on the printout.
• The Near PD value is calculated based on the ADD.
• ( ) appears when normal measurement is not expected due to eyelid,
eyelash, or blinking.
• *-mark appears when normal measurement is not expected with the
button selected.
