2. Safety Notice
Please read the following precautions carefully to avoid personal injury, device damages
or other possible hazards:
2.1 Before use
●No technical demands for operator, and read manual before using.
●Do not posit the equipment to make it difficult to operate the power plug which uses to isolate
the equipment circuits electrically form the supply mains.
●Do not use the device for other than the intended purpose.
YEASN will not be responsible for accidents or malfunction caused by such carelessness.
●Never modify or touch the internal structure of the device.
This may result in electric shock or malfunction.
Do not store the device in an area that is exposed to rain or water, or contains poisonous gas or
liquid.
Corrosion or malfunction of the device may occur.
●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.
●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.
