●Avoid using the device in a place exposed to direct sunlight or near incandescent light.
Under such circumstances, the device may work irregularly or issue error messages.
●Be sure to use a wall outlet which meets the power specification requirements.
If the line voltage is too high or too low, the device may not give full performance. Malfunction
or fire may occur.
●The electrical outlet must have a grounding terminal.
Electric shock or fire may occur in the event of malfunction or power leakage.
●Insert the main plug into an outlet as far as the prongs of the plug will go.
Fire may occur if the device is used with a loose connection.
●For supplying the device with the power, never use a table tap or extension cable.
The electrical safety may be lowered.

5
●Do not place heavy objects on the power cord.
The damaged power cord may cause fire or electric shock.
●Before connecting a cable, turn off the power switch and disconnect the power cord from
outlet.
Malfunction of the device may occur.
●To transport the device, use the special packing materials to protect the device from impact of
dropping.
Excessive vibration or impact to the device may cause malfunction.
●In installation and operation of the device, observe the following instructions about EMC
(electromagnetic compatibility):
—Do not use the device simultaneously with other electronic equipment to avoid
electromagnetic interference with the operation of the device.
—Do not use the device near, on, or under other electronic equipment to avoid electromagnetic
interference with the operation of the device.
—Do not use the device in the same room with other equipment such as life-support equipment,
other equipment that has major affects on the life of the patient and results of treatment, or other
measurement or treatment equipment that involves small electric current.
—Do not use the device simultaneously with portable and mobile radio frequency
communication systems because it may have an adverse effect on operation of the device.
—Do not use cables and accessories that are not specified for the device because that may
increase the emission of electromagnetic waves from the device or the system and decrease the
immunity of the device to electromagnetic disturbance.
●The Electromagnetic Compatibility Directive sets the essential requirements for electrical and
electronic equipment that may disturb, or be disturbed by, other equipment. The CCQ-800
complies with these requirements. Follow the guidance in the tables for use of the device in an
electromagnetic environment.
●Ground wire should be installed indoor and the instrument should be grounded well.
●The instrument should not be installed in place where disconnection is not possible.
2.2 Using
●Immediately replace the power cord if the internal wires are exposed, turns on or off the table
when the power cord is moved, or the cord and/or plug are too hot to be held with hands.

6
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, then contact your authorized distributor.
These limits are designed to provide reasonable protection against harmful interference in a
standard medical installation .
This device generates uses and can radiate radio frequency energy and, if not installed and used
in accordance with the instructions, may cause harmful interference to other devices in the
vicinity.
However, there is no guarantee that interference will not occur in a particular installation. If this
device does cause harmful interference to other devices, which can be determined by turning the
device off and on, the user is encouraged to try to correct the interference by one or more of the
following measures:
Reorient or relocate the receiving device.
Increase the separation between the devices.
Connect the device to an outlet on a circuit different from that to which the other device(s) are
connected.
Consult the manufacturer or field service technician for help.
●Never use the device with cables or accessories other than the designated ones.
Malfunction caused by deteriorated electromagnetic compatibility (EMC) characteristics may
occur.
●Never use portable and mobile radio frequency (RF) devices in the vicinity of this device.
These devices may adversely affect medical electrical equipment and malfunction may occur.
●When moving the device, do not place your hands on the frame of the display but hold the
underside and sides with both hands.
Injury or malfunction may occur.
2.3 After use
●When the device is not in use, turn it off and cover the dustproof cover. Otherwise dust will
affect the measurement accuracy.
●Clean the prongs of the main plug with a dry cloth often. If dust settles between the prongs, the
dust will collect moisture, and short circuit or fire may occur.

7
●If the device will not be used for a long time, disconnect the power cord from the wall outlet,
as fire may occur.
●Notification: Any serious event related to the device to the user and/or patient shall be reported

Turn the lens pushing board lever until it touches and parallel the bottom of the frames.
c. Fix lens with lens pressing unit
Raise the lens pressing unit, and then lower it slowly to fix the lens.
6.3 Measuring Single Vision Lens
Single vision lenses are measured on the Auto Identification Measurement Mode or Normal
Measurement Mode, the procedure is as follows:
a. Specify lens side if necessary
Specify lens side by pressing R/L shortcut tab. If it's automatic R/L switch mode, the instrument
automatically identifies the first measured lens as the right lens. After the measured data is fixed,
it goes automatically to left lens measurement.
●If lens side is only specified after measurement, the measured data will be cleared.
b. Perform lens alignment
Move the lens to bring target close to the center of alignment circle. If it's framed lenses, move
the lens pushing board along the frames. When alignment is finished, make sure that the bottom
of the frames is touched with lens pushing board.
c. Fix measured data
When alignment is finished, the measured data is fixed by pressing Read key in manual read
mode or automatically fixed under auto read mode.
●Cylinder indication shortcut tab still works in terms of changing the indication mode of
cylinder value even after measured data is fixed.
d. Measuring other lenses
If it is necessary to measure the other lenses, then follow the same step as above.
e. Print measured data
When the measurement is completed, press "Print" to print out the measured data.
If needs be, the measured data can be sent to other instruments, computer, for example, by
setting parameter in "Data Output" and connecting to other instruments.
6.4 Measuring Multifocal Lens
Bifocal measure step: distance portion---near portion (as to trifocal lenses, the order is distance
portion --- middle portion --- near portion)
●Measure lens under auto and normal model.
