1-1.
DANGER
Death or serious injury, damage to equipment or a fire will result if the instructions given below are not followed.
Turn the lighting switch off before replacing the fluorescent lamp. The fluorescent lamp becomes hot immediately after use. Before replacing the fluorescent lamp, make sure that it has cooled down sufficiently.
Do not replace the fluorescent lamp with wet hands. Be sure to keep the admittance panels and the access ports closed when using the unit. If an admittance panel or an access port is left open when the unit is in use, the infant may fall out of the baby compartment. Be sure to keep the admittance panels and the access ports closed during phototherapy when an infant is in the incubator.
Do not leave the unit unattended when an admittance panel or an access port is open. If an admittance panel or an access port is left open, the infant may fall out of the baby compartment and sustain life threatening injury. Never leave the unit unattended when an admittance panel or an access port is open.
If an admittance panel, a snap-open access port or a hook slider should be found loose or faulty, stop using the unit immediately and ask for repair. The infant may fall out of the unit.
Always check the admittance panel operating knobs and the hook sliders of the snap-open access ports for proper operation. If the front admittance panel or a snap-open access port should not close securely, do not place any infant in the unit and ask for the problem to be corrected. Do not open an admittance panel or an access port in order to lower the incubator air temperature. Because the incubator air temperature is controlled automatically at a set temperature, the heater output will increase dangerously to make up for any temperature drop.
Open and close the snap-open access ports gently. If you open or close them with to much force, they may not open or close properly, which is dangerous.
After the infant is placed in the incubator, check again that the admittance panels and the access ports are all closed securely. For the infant’s safety, never leave the incubator unattended when an admittance panel or an access port is open.
− 10 −
Do not fasten the infant fixing bands too tightly. If they are fastened too tightly, they could injure the infant.
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 an 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 experience an 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.
Ground the unit securely. Otherwise, a leakage current may cause an electric shock. In order to complete the ground connection, connect the power cord only to a 3P power outlet including a ground terminal which is grounded properly. Do not operate the unit if you have any doubt about its ground connection.
Do not use a device generating high frequency near the unit. To prevent malfunction of the unit due to jamming, do not use electric surgical knives, portable and mobile communication equipment and other devices which generate high frequency near the unit during its operation.
Analyze arterial gas levels repeatedly when a high oxygen environment is required. It is reported to be extremely important and essential to repeatedly analyze arterial gas levels, when the infant’s conditions call for a high oxygen environment, 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 a risk of retinopaths of prematurity and other adverse effects.
Do not jolt or drop the unit or allow it to be struck by other objects. The screws or fixed parts may become loose.
Be sure to insert the power plug fully into a power outlet. Incomplete insertion of the plug may cause heat to generate and a fire may result.
Check the power outlet regularly to make sure that it presents no abnormality. A loose or damaged outlet can cause a poor electrical connection, which may generate heat and result in a fire.
Keep the area around the power plug and power outlet free of dust. Accumulated dust on the plug can cause heat to generate and may lead to a fire.

WARNING
Death or serious injury due to a fire or an electric shock will result if the instructions given below are not followed.
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. Be sure to follow the doctor’s instructions in setting the incubator air temperature. Be sure to follow the doctor’s instructions in setting the oxygen concentration in the incubator. Use only oxygen certified for medical use. Be sure to bear in mind the following precautions during oxygen supply. 쎲 Do not place a body warmer, a flashlight, oils and fats, or flammable vaporizable matters in the incubator. 쎲 Use pure cotton for the infant’s clothing and bed sheets, etc. Do not use any material that is easily charged with static electricity. 쎲 Use pure cotton or fire-proof materials for the clothing of doctors, nurses and those ambulance staff who handle this unit.
Bear in mind the following precautions while using oxygen supply equipment. 쎲 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. 쎲 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 first and then to supply oxygen again.
The electrolyte may leak out if the oxygen sensor should be damaged. If you should come in contact with the electrolyte, wash the site immediately and thoroughly with copious amounts of water. 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. 쎲Do not pinch the power cord between the unit and the wall, a shelf or the floor. 쎲Do not place the power cord near a heating apparatus or heat it. 쎲Do not put anything heavy on the power cord. 쎲Always 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.
− 12 −
Use only the power cord supplied with the unit. Otherwise a fire or an electric shock may result.
Before sanitizing the unit, be sure to turn off the unit, remove the power plug and check 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. In order to complete the ground connection, connect the power cord only to a 3P power outlet including a ground terminal which is properly grounded. 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 source other than that specified. The unit should be serviced only by qualified personnel. Be sure to inspect the unit before starting a day’s work. Operating the unit without inspecting it before starting a day’s work may let a defect pass unnoticed and cause a serious accident.
1-3.
CAUTION
Injury or damage to nearby objects may result if the instructions given below are not followed.
If the unit has been kept disconnected from the electrical outlet for a long period of time (for about 3 months), the internal battery will be left in a discharged condition. Turn the power switch to the ON position. If the charge level indicator of battery 1 or 2 does not come on, plug the power cord in the electical outlet to charge the battery.
− 13 −
Be sure to clean and disinfect the unit before using it for the first time after purchase. The unit is shipped without being disinfected.
When inserting a cord or a tube into the unit, be careful not to let it wind around or squeeze the infant inside. 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 and stability of the place where the unit is to be placed or installed.
Install the unit out of reach of small children. Do not install the unit in direct sunshine or near a heating apparatus. Do not place anything heavy on the unit. Check the operation of the peripheral devices. If a device transmitting of 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.
Be sure to cover the mattress with a mattress sheet. Do not place any baby directly on the mattress.
Be sure to attach the semi-iris access port cover to the snap-open access port packing. If you open the snap-open access port without attaching the semi-iris access port cover, the incubator air temperature and oxygen concentration will drop.
