1-1.

DANGER

Death or serious injury will result if the instructions given below are not followed. Do not use the unit in the presence of a flammable anesthetic gas. The unit may cause an explosion or a fire if used in the presence of such a gas. Use the unit only for an infant to whom phototherapy has been prescribed by the doctor in charge.

1-2.

WARNING

Death or serious injury due to a fire, an electric shock, tipping over of the unit, etc. will result if the instructions given below are not followed. Be sure to inspect the unit at the start of each day. Operating the unit without inspecting it at the start of each day may let a defect pass unnoticed and cause a potentially unfavorable outcome. Do not look directly at the LED light. Cover the infant’s eyes with an eye protector during phototherapy treatment. Otherwise, damage may occur to the infant’s eyes. Before using the unit, be sure to check that there is no risk of the infant falling off the incubator, the infant warmer, etc. Make sure that the infant will not fall off even if he or she moves. The electrical rating of this unit is as follows: Rating: AC100-240V; Power consumption: 30VA; Frequency: 50/60Hz; Operating voltage range: AC100-240V±10%. Do not connect the unit to any other power source. Before using the unit, be sure to check that the arm mount is attached securely to the incubator or the infant wamer. If the arm mount is not attached securely, the unit may fall and cause an electric shock. Be sure to fix the upper support column of the Stand Type securely with the fixing knob and the auxiliary fixing knob to prevent it from sliding down. Take care of the usage environment. Using the unit in a strong electromagnetic environment may affect the irradiance level or turn OFF the light source output. 8

Operating Precautions

Avoid damaging the power cord. A damaged power cord may cause a fire or an electric shock. ••Do not get the power cord caught between the unit and the wall, a shelf or the floor. ••Do not place the power cord near a heating apparatus or heat it.

PLEASE READ WITHOUT FAIL

Do not use the unit next to other devices. Using the unit next to or stacked with other devices may cause malfunction. When it is unavoidable to do so, it is necessary to check that the unit and the other devices are operating correctly.

••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 must be replaced immediately with a new one. Do not use a power cord or AC adapter other than the one supplied with the unit. Otherwise, a fire or an electric shock may result. A power cord or an AC adapter other than the one supplied with the unit can generate high frequency noise, cause jamming to other electric devices for medical use and thus result in malfunction. In addition, when such a power cord or an AC adapter is used, the unit may become susceptible to high frequency noise generated by other electric devices and thus result in malfunction. Do not touch the power plug with a wet hand. Touching the power plug with a wet hand may cause an electric shock. The unit should be located near a power outlet to prevent accidental contact with a power cord. Use a separate power outlet for each unit. Do not use adapters to attach multiple devices to the same power outlet the unit is connected to. 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. Do not disassemble or modify the unit. Disassembling or modifying the unit may cause a fire, an electric shock or injury. Do not use parts and accessories other than those specified for the unit. Otherwise, the unit may malfunction or break down. Place the unit in such a way that an infant adjacent to it will not be exposed to phototherapy light. If phototherapy light should get in the eyes of an infant who is not receiving phototherapy treatment, problems may occur to his or her eyes. Cover the eyes of an infant ajacent to the unit with a phototherapy mask if necessary. Nursing staff should be cautious about symptoms of visual discomfort. Staying in an irradiated area for a long time may cause a headache, nausea or mild vertigo. To reduce such symptoms, use the unit in a well-lighted area or wear glasses with yellow lenses. Turn off the unit while the infant is being taken care of under the unit. 9

Operating Precautions

The unit does not use a cold light. Temperature on the top surface of the mattress will rise approximately 5°C above the ambient temperature. Do not use the unit in a high oxygen environment. The unit is not designed to be used in a high oxygen environment. Operate the unit in the presence of room air. Do not pour any liquid directly on the unit. Otherwise, a fire, an electric shock or damage to the unit will result. If a copious amount of liquid should be poured on the unit accidentally, wipe it off immediately and check the electronic circuits inside the unit. Do not operate the unit where it is exposed to excessive humidity, dust or steam. Operating the unit in such a place may cause a fire or an electric shock. Do not place photosensitive medicines near the unit. Photosensitive medicines may deteriorate when exposed to phototherapy light. Never place or store such medicines near or within the irradiated area. Stop using the unit immediately if any trouble is detected. If the unit does not function normally, stop using it immediately, indicate on the unit clearly that it is out of order and contact your local Atom representative. The unit should be serviced only by qualified personnel according to an appropriate service manual. Be sure to lock the caster stopper on stand type caster when the unit is not to be moved. As Mount Types are only designed for incubators, they must not be applied to other products. Be sure to attach the F-Rail Attachment or Pole Mounting Attachment of the Mount Type to the power source part. Also, when mounting the Pole Mounting Attachment high-load or the F-Rail Attachment to the Arm Type, be sure to attach it to the arm mount of the unit. Be sure to connect the relay cable of the unit to the connector area of the irradiation head of the Mount Type. Do not also connect the relay cable to any other product than the unit. It may cause damage to the equipment. Be sure to attach the irradiation head of Mount Type to the top surface of the incubator hood. Do not attach it to the sloping section of the hood whenever possible. Do not also attach it to the curved surface of the hood. It may cause the irradiation head to fall off the hood. Before attaching the irradiation head of the Mount Type, be sure to check the surface of the hood and suction pad, and do not attach the irradiation head if either of them is damaged. If so, the adhesiveness of the suction pad is reduced, so that it may cause the irradiation head to fall off the hood.

10

Operating Precautions

Before attaching the irradiation head of Mount Type, be sure to clean the hood surface and suction pad. If dust or dirt adhere to the surface and suction pad, the adhesiveness of the suction pad is reduced, so that it may cause the irradiation head to fall off the hood.

PLEASE READ WITHOUT FAIL

The Mount Type must not be used for treatment while the canopy of Dual Incu i is being raised. Be sure to perform the treatment with the canopy being lowered. As the irradiation distance from an infant under treatment to the unit is too long when the canopy is raised, the efficacy of treatment will be reduced.

Check that the relay cable of the Mount Type is positioned where it neither hinders the operation of the incubator, etc. nor the treatment of a patient. Do not get the relay cable of the Mount Type caught. It may cause the cable to be broken. Be sure to check that the relay cable is not pinched before inserting the irradiation head into the holder. When trying to insert the irradiation head into the holder with the relay cable of the Mount Type being pinched between the head and power source part, the irradiation head cannot be reliably fixed to the power source part. It may lead to the irradiation head’s falling off. Only attach the Arm Type to the I.V pole. Do not attach it to the I.V stand. Doing so may cause it to fall over.

1-3.

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. Before using the unit, it is recommended that you measure the irradiance level of the unit according to “3-1. Measuring the Irradiance Level”, and follow the doctor’s treatment policy. The unit should be operated within the ambient temperature of 10-30ºC. Do not operate the unit outside of the temperature range mentioned above. When the LEDs are used properly, deterioration of their light output can be minimized throughout their service life. The LEDs operate for approximately 10,000 hours. However, if they are used in an environment outside the operating conditions, their service life may be reduced. Be sure to clean the irradiation head cover. If the irradiation head cover is dirty, radiant energy will be reduced and the infant may not be treated properly.

11

Operating Precautions

Bear in mind the following points when operating the unit. 1. Endeavor to identify the cause of neonatal jaundice (hemorrhage, infection, bleeding, etc.) and provide appropriate causal therapy concurrently. 2. The infant’s skin color becomes less correlated with his or her serum bilirubin level during phototherapy treatment. Therefore, readings obtained by the icterometer are not reliable at all. Measure the infant’s serum bilirubin level at least once a day. It has been reported that in very rare cases, separated serum may assume a brownish tinge (methemalbuminemia). 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 and disinfecting the unit. Cleaning and disinfecting the unit with the power plug connected to the power outlet may cause an electric shock. Install the unit on a stable surface. Installing the unit on an unstable platform or a tilted surface will cause it to fall or drop and may injure someone. Therefore, before installing the unit, make sure that the place where the unit is to be installed is stable and strong enough to support the weight of the unit. Install the unit out of reach of small children. Do not operate the unit covered with a cloth, etc. Operating the unit covered with a cloth or pressed tightly against a wall may cause a fire or an electric shock due to overheating. Do not install the unit in direct sunlight or near a heating apparatus. Do not place anything heavy on the unit. Do not let the unit hit anything or let it fall over. Do not drop it. After operating the Arm Type, be sure to fold the arm and then move the unit to a storage area by holding the arm base. After operating the Stand Type, be sure to fold the arm, slide down the upper support column to the lowest position and tighten the fixing knob and the auxiliary fixing knob. Then unlock the caster stopper, move the unit to a storage area by holding the stand column and lock the stopper. Phototherapy can disturb the water balance of the patient. Make sure that the water balance of the patient is maintained during phototherapy treatment. Be sure to push the lever of the suction pad of the Mount Type until it reaches the end.

12

Operating Precautions

As the adhesiveness decreases, which may cause the irradiation head to fall off, when the suction pad of the Mount Type is dirty, be sure to clean the pad with a soft cloth dampened with a disinfectant solution and wipe it again with a soft dry cloth after use.

PLEASE READ WITHOUT FAIL

Do not forcibly try to remove the irradiation head from the holder while the suction pad of the Mount Type is fixed to the power source part. Be sure to remove the suction pad before removing it from the incubator. It may cause damage to the equipment.

Remove the irradiation head of the Mount Type when raising or lowering the canopy of the Dual Incu i. If you raise or lower the canopy when the irradiation head is attached, strain is placed on the canopy, which may cause the emergency stop alarm to sound. Since phototherapy treatment may increase the body temperature of the child, use the servo control mode to control the temperature in the incubator and the infant warmer. In case the body temperature of the child goes up, lower the incubator air temperature setting. Please be aware that the bilirubin photoisomer may cause a toxic effect. Please be careful when using reflective foil, as the child’s body temperature may reach a dangerous level. Do not place anything that interrupts or deteriorates the light irradiating the child. This equipment treats high bilirubin polycythemia by irradiating the child. If light does not reach or deteriorates, the curative effect will decrease.
