During Use
WARNING
• Before starting NT measurement, set the safety stopper for each patient to prevent the
air nozzle from touching the patient’s eye.
Contact between the air nozzle and the eye may damage the cornea.
CAUTION
• Before use, perform visual and operation checks. If abnormal conditions are
encountered, stop using the device.
If the device is used under abnormal conditions, intended results may not occur. Also
unexpected malfunctions or health hazards may occur due to improper measurement.
• Be sure to connect an interface cable, checking the symbols of input (IN: ) and
output (OUT: ).
Data transmission may not be performed properly.
• Take care not to catch hands or fingers in moving parts (measurement part and chin
rest). Be sure to give this caution to patients.
Hands or fingers may be pinched and may result in injury.
• When measuring, caution patients not to touch the NT measurement part.
When switching from NT measurement to R/K measurement, the air nozzle recesses
and the shutter closes at which time fingers may be caught in the shutter. (In this case,
the cover stops immediately and does not result in injury.)
• Every time before treating a different patient, clean the patient’s contact area (chin
rest and forehead rest) using disinfectant alcohol.
If chinrest paper is used, remove one piece for each patient.
• Keep the measuring window free of fingerprints and dust.
The measurement accuracy may decrease substantially.
• In the event of smoke or strange odors, immediately turn off the device and
disconnect the power plug from the outlet. After you are sure that the smoke has
stopped, then contact NIDEK or your authorized distributor.
Usage of the device under such abnormal conditions may cause fire or electric shock.
In case of fire, use a dry chemical (ABC) extinguisher to extinguish the fire.
• Immediately replace the power cord if the internal wires are exposed, the device turns
on or off when the power cord is moved, or the cord and/or plug are too hot to be held
with hands.
This may result in electric shock or fire.
In the event of malfunction, disconnect the power cord from the wall outlet. Never touch
the inside of the device and contact NIDEK or your authorized distributor.
• Never press the LCD display with a hard object such as a ball-point pen. Keep
magnetic objects away from the LCD display.
The device may be damaged.
• Do not operate the LCD display with wet hands.
Water seeping into the device may result in failure of the device.
