1-1.

DANGER

Death or serious injury, damage to equipment or a fire will result if the instructions given below are not followed. Monitor the infant’s skin temperature when operating the unit. The operator must monitor the infant’s skin temperature when operating the unit. Avoid unattended use of the unit. Do not leave the unit unattended with the baby guards folded down. If the baby guards are left folded down, the infant may fall out and get fatally injured. Never leave the unit unattended with the baby guards folded down. Do not tilt the mattress platform with the baby guards folded down. If the mattress platform is tilted with the baby guards folded down, the infant may fall out. When you pull up and lock the baby guards in position, be sure to check that no mattress sheet or linen is caught between any of the baby guards and the mattress platform. Make sure that the baby guards are locked securely. If linen or other object is caught between any of the baby guards and the mattress platform, remove it. Otherwise, the baby guards will not be locked completely. The baby guards may swing down and the infant may fall out of the unit and suffer serious or fatal injury. Stop using the unit immediately and seek repair if the locking mechanism of the baby guards or other related parts should be found faulty in any way. The infant may fall out. Never place a body warmer or any other possible ignition source in or near the unit. Use of oxygen will increase the risk of explosion or fire. Body warmers or other devices in which fire is used or which will 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 cause an explosion or a fire if used in the presence of such a gas. Do not use ether, alcohol or any other ignitable substance. Even a small amount of ether, alcohol or any other ignitable substance may cause a fire when mixed with the oxygen supplied to the unit. Do not hang any flammable materials on the canopy. It may cause a fire.

Operating Precautions

PLEASE READ WITHOUT FAIL

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 properly grounded 3P power outlet including a ground terminal. 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. When the infant requires a high oxygen environment, it is extremely important and essential to periodically analyze arterial gas levels. Follow the doctor’s instructions in measuring the oxygen concentration because ignoring essential requirements may increase the risk of retinopathy of prematurity and other adverse effects. Do not give a shock to the unit or let it hit anything. The screws or fixed parts may become loose. If the unit is to be used beyond its expected life span, overall repairs including replacement of parts must be carried out.

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 infant’s skin temperature. Be sure to follow the doctor’s instructions in supplying oxygen. Use only oxygen for medical use. Be sure to bear in mind the following precautions during oxygen supply. • Do not place a body warmer, a flashlight, oils and fats, or flammable vaporizable matters near the unit. • Use pure cotton for the infant’s clothing, bed sheets, etc. Do not use any material that is easily charged with static electricity. • Use pure cotton or fire-proof materials for the clothing of doctors, nurses and ambulance staff who handle this unit. Bear in mind the following precautions 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, piping, connections and other parts of 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.

11

Operating Precautions

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 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. • 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. Do not touch the heater with your hand when the heater is on. You may burn yourself. 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. Before cleaning and disinfecting the unit, be sure to turn the power switch off, remove the power plug, and allow the heater temperature to drop sufficiently. 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 properly grounded 3P power outlet including a ground terminal. 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 outlet other than that specified. The unit should be serviced only by qualified personnel. Be sure to inspect the unit at the start of each day. Operating the unit without inspecting it before at the start of each day may let a defect pass unnoticed and cause a potentially unfavorable outcome.

12

Operating Precautions

1-3.

PLEASE READ WITHOUT FAIL

Check for conformity to the applicable standard if the unit is going to be connected to another medical device for use as a system. Accessory equipment connected to the analogue and digital interfaces must comply with the relevant IEC standards (e.g. IEC 60950 for data processing equipment). Furthermore all configurations should comply with IEC 60601-1-1. But the items that are not specified as part of the system should not be connected. Anybody who connects additional equipment to the signal input or signal output configures a medical system, and therefore should make the medical system comply with the requirements of IEC 60601-1-1 on his or her own responsibility. If in doubt, consult your local Atom representative.

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. During the standby mode, be sure to preheat the unit in order to keep the mattress surface temperature stable. Place the infant on the mattress only after the mattress surface 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. When feeding the cords and tubes into the unit, be very careful not to let them wind or tighten around the patient. 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 with the canopy covered with a cloth, etc. Operating the unit covered with a cloth or pressed tightly against the 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.

13

Operating Precautions

Do not expose the unit to extraordinarily high temperature or excessive humidity. Do not place anything heavy on the unit. Do not let the unit hit anything, fall, or drop inadvertently. Do not attach any peripheral device that is not specified by Atom to 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 the 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. The mattress is not breathable and may cause a bedsore.
