1-1.

DANGER

Death or serious injury, damage to equipment or a fire will result if the instructions given below are not followed.

Be sure to close the front admittance panel and access ports when the unit is in use. Using the unit when the front admittance panel or an access port is left open may cause the infant to fall out of the baby compartment. Be sure to close the front admittance panel and access ports even when performing phototherapy on an infant inside the incubator.

If the incubator air temperature rises when performing phototherapy, proceed with phototherapy after placing the infant in a cot or an open incubator (infant warmer), according to the doctor's judgment. Since growing infants release a high level of heat, the incubator air temperature may rise if you place the infant in the incubator and perform phototherapy. Also, if you use multiple phototherapy units at the same time, or if the room temperature is high, the incubator air temperature may rise. In this case, proceed with phototherapy after placing the infant in a cot or an open-type incubator, according to the doctor's judgment. Take sufficient care when using a cot, as it becomes difficult to watch the infant. Also, placing an ice bag inside the incubator has the effect of decreasing the temperature. However, be sure to close the front admittance panel and access ports in this case also.

Do not leave the unit unattended when the front admittance panel or an access port is open. If the front admittance panel or an access port is left open, the infant may fall out of the baby compartment and even lose its life. Never leave the unit unattended when the front admittance panel or an access port is open.

If the front admittance panel, a snap-open access port or a hook slider should be found loose or faulty in any way, stop using the unit immediately and ask for repair. The infant may fall out of the incubator.

Never place a body warmer or other possible ignition sources in or near the unit. Use of oxygen will increase a risk of explosion or a fire. A body warmer or other devices in which fire is used or which may generate a spark may cause explosion or a fire if used near the unit.

Do not use the unit in the presence of a flammable anesthetic gas. The unit may cause explosion or a fire if used in the presence of such a gas.

Do not use ether, alcohol or other ignitable substances. Even a small amount of ether, alcohol or other ignitable substances may cause a fire when mixed with the oxygen in the incubator.

−8−

Ground the unit securely. Otherwise current leakage may cause an electric shock. To complete the ground connection, connect the power cord only to a 3P power outlet including a ground terminal and grounded properly. Do not operate the unit if you have any doubt about its ground connection.

Do not use near the unit any device generating high frequency. Electro-Surgical apparatus, cellular phones and other devices which generate high frequency should not be used near the unit during its operation to prevent malfunction of the unit due to jamming.

Analyze arterial gas levels repeatedly when a high oxygen environment is required. It is reported to be extremely important and essential, when the infant's conditions call for a high oxygen environment, to repeatedly analyze arterial gas levels in order to maintain the oxygen concentration in the incubator at a desired level. Follow the doctor's instructions in measuring the oxygen concentration because ignoring essential requirements may increase the risk of retinopathy of prematurity.

Do not jolt the unit or bump it against anything. The screws or fixed parts may become loose.

1-2.

WARNING

Death or serious injury due to a fire or an electric shock will result if the instructions given below are not followed.

Be sure to follow the doctor's instructions in setting the incubator air temperature or the infant's skin temperature. Be sure to follow the doctor's instructions in setting the relative humidity in the incubator. Be sure to follow the doctor's instructions in setting the oxygen concentration in the incubator. Oxygen for medical use should be used. Be sure to bear in mind the following points during oxygen supply. ● Do not place a body warmer, a flashlight, oils and fats, or flammable vaporizable matters in the incubator. ●Use pure cotton for the infant's clothing and bed sheets, etc. Do not use any material that is easily charged with static electricity. ●Use pure cotton or fire-proofed materials for the clothing of doctors, nurses and those ambulance men who handle this unit.

Bear in mind the following points while using oxygen supply equipment. ● If oil, grease or a grease-like substance should get in contact with pressurized oxygen, a violent spontaneous ignition may occur. Do not let such substances stick to the oxygen pressure regulator, the oxygen cylinder valve, pipings, connections and other oxygen supply equipment. ●On a high pressure oxygen cylinder, use only a tested pressure reducing valve or pressure regulating valve indicated specifically for oxygen supply. Do not use such a valve for any gas other than air or oxygen. It is dangerous to use a valve to supply a gas other than air or oxygen and then to supply oxygen again. −9−

Smoking is prohibited in the room where the unit is installed. Do not place any possible ignition sources in the room. Avoid damaging the power cord. A damaged power cord may cause a fire or an electric shock. ● Do not pinch the power cord between the unit and the wall, a shelf or the floor. ● Do not place the power cord near a heating apparatus or heat it. ● Do not put anything heavy on the power cord. ● Always grasp the power plug with your hand to remove the power cord from the power outlet. A damaged power cord should be replaced immediately with a new one.

Use only the power cord supplied with the unit. Otherwise, a fire or an electric shock may result.

Before sanitizing the unit, ensure that the unit is electrically disconnected and that the unit and the heater have sufficiently cooled down. Do not touch the power plug with a wet hand. Touching the power plug with a wet hand may cause an electric shock.

Do not disassemble or modify the unit. Disassembling or modifying the unit may cause a fire, an electric shock or injury.

Do not install the unit where it will be exposed to excessive humidity, dust or steam. Installing the unit in such a place may cause a fire or an electric shock.

The power outlet should be located near the unit to prevent accidental contact with a trailing power cord. Use a separate power outlet for each unit. Do not put many loads on one power outlet. Connect the power cord only to a 3P power outlet in order to complete the ground connection. Do not operate the unit if you have any doubt about its ground connection. Ground peripheral electric equipment securely. Never connect the unit to a power unit other than that specified. The unit should be serviced only by qualified personnel. Be sure to perform start-up inspection. Using the unit without performing start-up inspection may let a defect pass unnoticed and cause a serious accident.

CAUTION

Injury or damage to surrounding objects may result if the instructions given below are not followed.

Be sure to clean and disinfect the unit before using it for the first time after purchase. The unit is shipped without being disinfected.

Always keep the unit warm to maintain the incubator air temperature at a fixed level during the standby mode. Place the infant in the incubator only when the incubator air temperature has stabilized. Do not twist or pull the cords by force. If any defect should be found, ask an expert for repair without attempting to repair it yourself.

Remove the power plug from the power outlet before moving the unit to another place or when the unit is not going to be used for a long time. Moving the unit to another place with the power plug connected to the power outlet will damage the power cord and may cause a fire or an electric shock.

Remove the power plug from the power outlet before cleaning or disinfecting the unit. Cleaning or disinfecting the unit with the power plug connected to the power outlet may cause an electric shock.

Place the unit on a stable surface. Placing the unit on an unstable platform or a tilted surface will cause it to fall or drop and may hurt someone. Check the strength of the place where the unit is to be placed or installed.

Install the unit out of reach of small children. In performing phototherapy to the infant in the incubator, pay special attention to the infant's temperature and the incubator air temperature during the therapy. The infant's skin temperature and the incubator air temperature may rise due to the radiant energy of light.

Do not install the unit in direct sunshine or near a heating apparatus. Do not expose the unit to extraordinarily high temperature or excessive humidity. Do not place anything heavy on the unit. Check the operation of the peripheral devices. If a device transmitting or receiving weak signals is installed near the unit, it may be affected by the electromagnetic waves generated by the latter. Check the operation of peripheral devices for any effect before using the unit in clinical settings. Stop using the unit immediately if any trouble is detected.
