Operating Precautions
8
[1] Operating Precautions
Please follow the operating instructions described in this Service Manual & Parts List for the safe use of the
unit. The unit should be operated only by those who have been trained and instructed properly in its operation.
The unit should be operated only for its intended use.
1-1. DANGER
Death or serious injury, damage to equipment or a fire will result if the instructions given below are not fol-
lowed.
Only those who have been trained properly should operate the unit.
Be sure to keep the admittance panels and the access ports closed when the unit is in use.
Using the unit with an admittance panel or an access port left open may cause the infant to fall out of the baby
compartment. Be sure to close the admittance panels and the access ports when performing phototherapy on an
infant inside the incubator.
Monitor the infant’s skin temperature when operating the unit.
If the incubator air temperature should rise during phototherapy, proceed with the photo-
therapy after placing the infant in a cot or an open-type incubator (an infant warmer), as
directed by the doctor.
Since a mature infant emits much heat, the incubator air temperature may rise if you place the infant in the
incubator and perform phototherapy. The incubator air temperature may also rise if you use multiple photo-
therapy units at the same time or if the room temperature is high. In such a case, proceed with the phototherapy
after placing the infant in a cot or an open-type incubator, as directed by the doctor. Take sufficient care when
using a cot, as it becomes difficult to observe the infant. Alternatively, placing an ice bag inside the incubator has
the effect of decreasing the incubator air temperature.
However, be sure to close the admittance panels and the access ports in this case also.
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 get fatally
injured. Never leave the unit unattended when an admittance panel or an access port is open.
Stop using the unit immediately and seek repair if an admittance panel, a snap-open access
port or a press lever should be found loose or faulty in any way.
The infant may fall out of the baby compartment.
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 other ignitable substances may cause a fire when mixed with the oxygen
in the incubator.

Operating Precautions
9
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 in order to maintain the desired oxygen concentration in the incubator. Follow the
doctor’s instructions in measuring the oxygen concentration because ignoring essential requirements may in-
crease 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.
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 supplying oxygen.
Be sure to follow the doctor’s instructions in setting the oxygen concentration in the incuba-
tor.
Use only oxygen for medical use.
Be sure to bear in mind the following precautions during oxygen supply.
앫Do not place a body warmer, a flashlight, oils and fats, or flammable vaporizable matters in the incubator.
앫Use pure cotton for the infant’s clothing, bed sheets, etc. Do not use any material that is easily charged with
static electricity.
앫Use 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.
앫If 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.
앫On 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.

Operating Precautions
10
If the oxygen sensor should break or get damaged, the electrolyte inside may leak out of the
sensor. If you should come in contact with the electrolyte, wash it away 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.
앫Do not get the power cord caught between the unit and the wall, a shelf or the floor.
앫Do not place the power cord near a heating apparatus or heat it.
앫Do not put anything heavy on the power cord.
앫Always 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 cleaning and disinfecting the unit, be sure to turn the power switch off, remove the
power plug, and allow the incubator air temperature and the heater temperature to drop
sufficiently.
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 touch the heaters during use or shortly after use.
The heaters are so hot during use and shortly after use that you may get burned. Allow the heaters to cool down
sufficiently before touching them.
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 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.

Operating Precautions
11
PLEASE READ WITHOUT FAIL
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.
The doctor is responsible for making a decision on transporting a premature infant. Watch
the infant continuously during transport.
Transporting a premature infant is associated with a risk of intracerebral hemorrhage due to jolting during trans-
port.
Check for conformity to the applicable standard if the unit is going to be connected to an-
other medical device for use as a system.
Accessory equipment connected to the analogue and digital interfaces must comply with the relevant IEC stan-
dards (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 60601-1-1 on his or her own responsibility. If in
doubt, consult your local Atom representative.
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.
During standby, be sure to always preheat the unit in order to keep the incubator air tem-
perature stable.
Place the infant in the incubator only after the incubator air temperature has stabilized.
When feeding the cords and tubes into the unit, be very careful not to let them wind or
tighten around the patient.
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 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.

Operating Precautions
12
Install the unit out of reach of small children.
When performing phototherapy on the infant in the incubator, pay special attention to the
infant’s skin temperature and the incubator air temperature during the treatment.
The infant’s skin temperature and the incubator air temperature may rise due to the radiant heat generated by the
phototherapy unit.
Do not install the unit in direct sunlight 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.
Do not press strongly or rub the operation display of the control panel.
Pressing it strongly or rubbing it may damage the display or cause it to malfunction.
Be careful not to let any medical fluid adhere to the control panel.
Do not attach any peripheral device that is not specified by Atom to the incubator.
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 electromag-
netic 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.
When relocating the unit, watch your step so that you do not have your feet run over by a
caster.
Do not put your hand on an admittance panel when transporting the unit.
Pressing an admittance panel strongly may break it. At least two people are required to transport the unit by
holding the main body.
Watch out for any obstacles during transport.
If a peripheral device is attached to the main body, the unit may hit surrounding objects and get damaged or
broken.
