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
Page 14
