Never insert your fingers under the measuring head.  
Inform the patient of this, too.  
Careless insertion of fingers may cause injury by pinching.  
Do not use or apply any spray-typed cleaner near the instrument.  
If a drop of cleaner remains inside the measuring nozzle, the pa-  
tient’s eye may be injured during measurement.

Before carrying the instrument, be sure to affix it firmly by turning  
the fixing screw at the base.  
If the instrument is moved with the screw loosened, it may result in  
damage to the instrument.  
When moving the instrument, be sure to hold it at the bottom sur-  
face with two people. Carrying by one person may cause back inju-  
ry or injury by falling parts. Also, holding areas other than the bot-  
tom surface may cause pinching fingers between parts and injury  
by falling parts as well as damage to the instrument.  
13  
31  
Before measuring, set the safety stopper. If the safety stopper is  
not set, it may cause injury to the eye that comes in contact with the  
measuring window glass. Set the safety stopper separately for the  
right and left eyes.  
When setting the safety stopper, do it from the instrument side  
(safety stopper knob side).  
Setting from another position does not easily allow you to check the  
positions of the measuring window glass and the patient’s eye and  
may cause injury to the eye that comes in contact with the measur-  
ing window glass.  
31  
To clean the measuring window glass and the window glass inside  
the measuring nozzle, use ethanol. Using other chemicals may  
cause damage to the patient's eye during measurement.

lignment and Measurement  
It is recommended that you do intraocular pressure measure-  
ments several times. Since the intraocular pressure varies by  
heart beats and tears, often it is not possible to obtain exact  
measurement values by measuring only once or twice.  
MEMO  
The alignment operation can be performed with the control lever.  
Moving the machine body by the control lever  
When the machine body needs to be moved slightly back and forth or right and left,  
move the control lever in each direction.  
Operating the control lever  
(back and forth, right and left)  
Never insert your fingers under the measuring head.  
Inform the patient of this, too.  
Careless insertion of fingers may cause injury by pinching.  
CAUTION  
To move the measuring head vertically, turn the control lever right for raising and left  
for lowering.

When the machine body approaches the target eye, the alignment bar and “FOR-  
WARD” display appear on the monitor screen.

At this moment, be careful not to catch eyelashes and eyelids within the outer align-  
ment mark so as to ensure correct measurements.  
If the instrument is too close to the target eye, with regard to the alignment reference  
position, “TOO CLOSE” is displayed on the monitor screen, and if it is too far, “FOR-  
WARD” is displayed.  
The alignment bar is displayed as a broken line when the instrument is close to the  
target eye and as a solid line when it is far. Also, the alignment bar is shortened ac-  
cordingly as it approaches the alignment reference position.  
These factors are displayed only when the alignment dot is near the inner alignment  
mark.

If OVER is displayed, switch the measuring range to 0-60 and do the measurement  
again.  
MEASUREMENT UNDER MANUAL MODE  
Adjust the height of the automatic instrument table so that correct  
measurement values can be obtained by allowing the patient to un-  
dergo measurements in a comfortable position.

HOW TO PRINT OUT MEASUREMENT VALUES  
To avoid printer problems due to paper jams, do not feed paper  
if it is torn or creased.  
To avoid discoloring, particularly of the recording part, do not  
store the printer paper in holders made of materials containing  
plasticizers (ex., vinyl chloride).  
MEMO  
To avoid coloring in the white part and discoloring in the re-  
cording part, do not use bonds containing solvents. Use water  
bonds.  
The printer paper is heat sensitive and cannot keep records for  
long periods of time. Copy the records to other paper for stor-  
age.  
This machine can print out measurement values with the built-in printer.  
1 Return to the Measurement screen.  
2 Press  
on the control panel.  
Measurement values of the monitor screen are printed out.  
Upon printing, the measured values are deleted automatically from the screen.  
The ERR display is not printed. Also, printing can not be done when no measurement  
values exist. When a red line appears in the printer paper, replace it. For details  
about the replacement of paper, see “HOW TO SET PRINTER PAPER” on page 23.  
Again, use the 58-mm wide TF50KS-E2C (Japan) paper for the printer.  
When “PRINTER HEAD IS UP” is displayed, lower the paper retainer lever and press  
again.

leaning the Measuring Window Glass  
To secure auto alignment and correct measurement values, clean the measuring  
window glass after each day’s work.  
Clean the glass when “CLEAN THE MEASURING WINDOW GLASS” is displayed  
on the monitor screen.  
To clean the measuring window glass and the window  
glass inside the measuring nozzle, use ethanol. Using  
other chemicals may cause damage to the patient's eye  
CAUTION  
during measurement.  
Do not use tissues, as they may make the stain more notice-  
able.  
MEMO  
Do not use tweezers or gauze, as these may scratch the lens  
and glass surfaces.  
1 Prepare the ethanol.  
2 Using a blower, remove dust and dirt from the glass surface.  
3 Moisten the applicator with ethanol.  
4 Wipe the glass surface lightly with the applicator, from the center outward.  
5 Use a new applicator and wipe the glass surface in a similar manner; repeat this  
Wiping the glass surface

SPECIAL NOTES ON CLEANING  
leaning the Outer Cover  
Do not use or apply any spray-typed cleaner near the in-  
strument. If a drop of cleaner remains inside the measur-  
ing nozzle, the patient’s eye may be injured during meas-  
urement.  
CAUTION  
To avoid discoloring/deterioration of the plastic components, do  
not use volatile solvents (benzine, thinner, gasoline, etc.).  
MEMO  
When the outer cover, operation panel and the like become stained, clean them with  
a dry cloth. If the stain is extreme, a neutral detergent for tableware may be used by  
diluting it with tepid water. Soak the cloth in the solution, squeeze it out, and then  
use if to wipe off stains.
