SAFETY PRECAUTIONS: Usage Precautions
CAUTION
• In the event of smoke or strange odors, immediately turn off the device and disconnect the power
plug from the power outlet. After it is certain that the smoke has stopped, contact NIDEK or your
authorized distributor.
Use 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.
• Before measurement, explain the measurement purpose and method sufficiently to patients.
• Instruct the patient to look at the picture of a balloon with their eyes wide open. Start measurement
after confirming that the instruction is properly followed by the patient. Be careful not to perform
measurement while the device is misaligned to the patient's eye.
Proper measurement may not be performed.
• When the patient comes off from the device after measurement, instruct the patient not to stand up
while holding the chinrest support.
The device may topple over resulting in injury.
• Never press on the LCD with a hard object such as a ball-point pen. Keep magnetic objects away
from the LCD.
Malfunction of the device may result.
• There may be a few dead or constantly-lit pixels on the LCD. This does not represent failure of the
LCD; it is due to the structure of the LCD.
• Should the device fail, disconnect the power cord from the power outlet and contact NIDEK or your
authorized distributor without touching the interior of the device.
• After a long period of disuse, check for any abnormality before use.
• If the device is connected to a PC that does not comply with IEC 60601-1 (except one that uses an
AC adapter that meets the Class II requirements of IEC 60950-1), supply power to the device and
PC through isolation transformers.
Electric shock may result. Contact NIDEK or your authorized distributor for installing isolation transform-
ers.
• When connecting to peripheral equipment such as a PC through LAN port via a medical facility net-
work, insert or connect an isolation transformer between the medical electrical equipment and net-
work devices (HUB etc.), or the network devices and other electrical equipment.
Depending on the types or numbers of other electrical equipment connected to the network, electric
shock or malfunction/failure of the electrical equipment may occur. For installation of the network isola-
tion transformer, consult NIDEK or your authorized distributor.
• This device is classified as Group 1 set by ISO 15004-2:2007 Light Hazard and conforms to the
standard.
• Use devices that comply with IEC 60601-1 in the patient
environment. If any device that does not comply with IEC
60601-1 is to be used, use an isolating transformer or
common protective grounding.
The patient environment is the volume of space in
which contact can occur between the patient and any
part of the device or between the patient and any other
person(s) touching the device. Use devices that comply
with IEC 60601-1 in the patient environment. If any
device that does not comply with IEC 60601-1 is to be
used, use an isolation transformer or common protec-
tive grounding.
