Cleaning the Window Glass inside the Nozzle

• When the window glass inside the nozzle becomes stained, it makes the fixation tar-

get unclear, causing errors in auto alignment and measurement values. If the fixa-

tion target is unclear or measurement values with parentheses are frequent, clean

the window glass inside the nozzle.

• Clean the glass when “CLEAN THE CHAMBER GLASS” is displayed on the monitor

screen.

2Moisten the applicator with ethanol.

3Insert the applicator into the nozzle, lightly touch the glass surface, and turn the ap-

plicator a few times.

4Use a new applicator and wipe the glass surface in a similar manner; repeat this a

few times .

5Cleaning is completed when the grease is thoroughly removed.

If stains cannot be removed easily, call your dealer. Press for a air check to

confirm normal operation.

MAINTENANCE AND CHECKING

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.

CAUTION

• Do not apply unreasonable force to the measuring nozzle

while cleaning.

• To avoid problems, do not leave the cotton fibers inside.

• Be sure to use only the attached applicator.

MEMO

The used applicator contains grease and it only scatters grease if used again; the light

transmittance is not improved at all. Be sure to replace the applicator and use a new

one for each of these repeated cleaning operations.

When the window glass inside the nozzle becomes stained, it makes the fixation tar-

get unclear and “CLEAN THE CHAMBER GLASS” is displayed on the monitor screen.
