2. Safety precautions
2.1 Safety identification
In this manual, signal words are used to designate the degree or level of safety alerting.
The definitions are as follows.
CAUTION
CAUTION: Indicates a potentially hazardous situation which, if not
avoided, may result in minor or moderate injury or property damage
accident.
Even situations indicated by CAUTION may result in serious injury under certain conditions.
Safety precautions must be strictly followed at all times.
2.2 Safety precautions before use
CAUTION
The safety precautions and operating procedures must be thoroughly understood prior to
operation of the device. Use of the device outside the scope of this manual may cause
adverse events.
Do not open shell and do not touch the interior of the device. This may cause electric shock
or instrument failure.
Install and use the device in an environment that meets the following conditions.
Temperature：10℃- 40℃
Humidity：≤80%
Atmospheric pressure：760hPa - 1060hPa
A room with low dust and little light
A location free from vibration and shock
--- If the device is not installed and used under the above conditions, the reliability of

6
measured results is impaired, and malfunction may result. In addition, there is a
possibility of injury if the device receives shock and falls down.
Avoid storage the device near water, poisonous gas or liquid. The device may be corrosion or
failure.
Avoid installing the device where it is exposed to direct air-conditioning flow. Changes in
temperature may result in condensation inside the device or adversely affect
measurements.
Be sure to use a power outlet which meets the power specification requirements. If the
voltage is too high or too low, the device will not perform properly, and fire may occur.
To avoid the risk of electric shock, the equipment must be connected with the power supply
in the case of the protection of grounding equipment. Electric shock or fire may occur if the
device malfunction or electric leakage.
Do not use socket overload. This May cause fire.
Insert the power plug into the socket. Improper connections may cause a fire.
Never use a power strip or extension cable to supply the device with power. This may cause
failures and fire.
Do not place heavy objects on the power cord. A damaged power cord may cause fire or
electric shock.
Switch off the power switch and disconnect the power cord from the power outlet before
connecting the cable. Otherwise it may result in device failure
When moving the instrument, be sure to turn off the power switch, unplug the power cord
and the power cable, lock the head (with a lock sign),to avoid equipment falling that may
cause injury or equipment damage.
Special packing materials are used to protect the equipment during transportation.
Excessive vibration or shock can cause malfunction.
When installing and operating equipment, observe the following EMC instructions (EMC):
1. The device can’t be used in conjunction with other electronic devices to avoid
electromagnetic interference with other electronic devices.
2. The equipment can’t be used in the same room with other devices, including life support
devices, other devices that have a significant impact on the lives of patients and the results
of treatment and the measurement or treatment devices of small current.
3. The equipment can’t be used in conjunction with portable and mobile radio frequency
communication devices because of their electromagnetic interference may adversely affect
the operation of the device.
4. Don’t use cables and accessories other than those specified by the company. These may
increase the electromagnetic wave emitted by the equipment or system and reduce the
electromagnetic interference resistance of the device.
If there is a potential electromagnetic interference between the equipment and other
equipments, shielding measures should be taken or the location of the device to be
changed to reduce the possible interference.

2.3 Safety precautions during use
CAUTION
When the equipment is disuse, please turn off the power and cover the dust cover. If the
equipment is exposed for a long time, it may have dust, which will affect the accuracy.
Please check the equipment before the operation. If there is any abnormal, do not use the
equipment. The equipment used to abnormal conditions that may affect the accuracy of the
data, the unexpected failures or diagnosis errors may cause harm.
Before measuring each patient, clean the chinrest and forehead rest with clean gauze or
absorbent cotton. If necessary, dampen a cloth with rubbing alcohol and gently wipe them
off. If you use a Chinrest paper, a replacement for each patient.
Keep the measuring window free of fingerprints and dust. Also confirm that it is not dirty
before use, or else 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 power outlet. After it is certain that the smoke has stopped, contact
MSOC or your authorized distributor.
The continued use of the equipment under unusual circumstances may cause a fire or
electric shock. In case of fire, use a dry powder (ABC) fire extinguisher.
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.
Do not operate the LCD screen with wet hands. Water infiltration devices may cause
malfunction of the equipment
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.
Only after training qualified personnel can operate the instrument, or operate under its
guidance.
2.4 Safety precautions after use
CAUTION
If the device is a long period of disuse, disconnect the power supply. Dust may collect
moisture that may cause short circuit or fire.
Occasionally use a dry cloth to clean the tip of the power supply plug. If the dust falls on the
tip, water may be collected, resulting in a short circuit or fire.
Don't jerk when pulling out power line. This will destroy the metal line and may cause
electric shock, short circuit or fire.
Maintain the following environmental conditions during transport and storage of the device.
Temperature：-40℃- +55℃
Humidity：≤80%
Atmospheric pressure：700hPa - 1060hPa(transport)、500hPa - 1060hPa(storage)
A location with low dust
A location not exposed to direct sunlight

Special packing materials are used to protect the equipment during transportation.
Excessive vibration or shock can cause malfunction.
2.5 Maintenance and check
CAUTION
Do not wipe any part of the instrument with a solvent or a strong cleaning solution.
Otherwise the instrument may be damaged.
Do not use organic solvents such as paint thinner to clean the outside of the device.
Otherwise the surface of the equipment may be damaged.
Avoid touching the optical components of the instrument to prevent performance
degradation caused by fingerprints or grease stains on the lens set.

trained by MSOC.
Adjustments must be made by the technical service personnel of MSOC or other authorized
personnel.
The battery of the instrument must be replaced by the technical service personnel of MSOC
or other authorized personnel.
When the equipment is returned to the company for repair or maintenance, use a clean
cloth dipped in the alcohol disinfection device (especially the area of patient contact).
When there is a big difference between the results of the Auto ref/keratometer
measurements and the subjective measurements, please contact MSOC or the dealer to
determine whether the current equipment requires calibration of the measurement
accuracy.
2.6 Disposal
CAUTION
Follow local governing ordinances and recycling plans regarding disposal or recycling of
device components.
It is recommended to deal with industrial waste by the designated contractor.
Deal with packaging material in accordance with local laws and regulations.
