2. General Precautions
2-1. DANGER
Death or serious injury, damage to equipment, or a fire will result if the instructions given below are
not followed.
Do not use or repair the unit where an explosive oxygen, nitrous oxide or a flammable
anesthetic gas is used.
2-2. WARNING
Death or serious injury due to a fire or an electric shock will result if the instructions given below
are not followed.
Do not operate or repair the unit with wet hands.
Connect the power cord of the unit to a power outlet including a ground terminal and meeting
the rated power requirements of the unit.
Be sure to disconnect the unit from the power source before handling the unit.
If a fingertip or a tool should touch a harness or a terminal in the unit, an electric shock
or a short circuit may result.
2-3. CAUTION
Injury or damage to ambient objects may result if the instructions given below are not followed.
Only qualified personnel authorized by Atom or a service representative properly trained in
the handling of the unit should inspect, repair, change the settings of, or disassemble and
assemble the unit.
Do not operate or repair the unit in electromagnetic environments where electrosurgical
knives or imaging devices such as magnetic resonance imaging (MRI) devices and
computerized tomography devices are used, or near a device equipped with an electromotor
that will consume a lot of electric currents.
The electronics of the unit may be affected by the radiation of various electromagnetic
waves in the hospital and may cause a malfunction of the unit.
Do not disinfect the unit by immersing it in a medical fluid. Avoid autoclaving or sterilization
with ethylene oxide gas (EOG).
Do not immerse the unit in water or a medical fluid.
If a portion of the water or the medical fluid should enter the unit, it may short an
electronic circuit inside.
After inspecting, repairing and disassembling and assembling, changing the settings of, or
disinfecting the unit, check that the unit operates normally.

8
The use of accessories and cables other than those sold by Atom as replacement parts for
internal components may result in increased emission or decreased immunity of the unit.
The unit or the system should not be used adjacent to or stacked with other equipment. If
adjacent or stacked use is necessary, observe the unit or the system to verify normal
operation in the configuration in which it will be used.
In replacing parts, make sure that the new parts you intend to use are those specified by
Atom.
Replacing parts with the ones not specified by Atom may compromise the safety of the
unit.

Turn on the unit, and the start screen will appear on the display. It is then replaced by the
numerical value screen. Three different screens are available by pressing the (screen
changeover) switch: the numerical value screen, the trend 1 screen and the trend 2 screen.

15
4-3-1. Numerical Value Screen
The numerical value screen is the screen that is displayed unless otherwise selected. It consists of
three areas: the numerical value area, the message area and the time area.
●Numerical value area
This area displays all the numerical data including the selected temperature, the incubator air
temperature, the skin temperatures, the relative humidity, the oxygen concentration, %SpO2, the
pulse rate and the settings.

16
●Message area
(1) This area displays information on the weight monitor
most of the time.
(2) If a switch is operated, or an alarm should occur, a
corresponding message will be displayed.
＊When the measurement section of the weight
monitor is not connected, “OFF” is normally
displayed. Messages, etc. will appear when an
operation or an alarm occurs.
●Time area
This area displays the current time and the alarm
silence indicator. Date is displayed in the
month/day/year format above. Time is displayed in
the hour/minute format below.
The alarm silence indicator appears when the
audible alarm is silenced.

17
4-3-2. Trend 1 Screen
The trend 1 screen displays the temperatures, the relative humidity and the oxygen concentration
graphically. It consists of four areas: the numerical value area, the temperature graph area, the
relative humidity & oxygen graph area, and the time area.
＊Settings are not displayed on this screen.
●Numerical value area
This area displays the incubator air temperature,
the skin temperatures, the relative humidity, the
oxygen concentration, %SpO2and the pulse rate.
＊Settings are not displayed in this area.
●Temperature graph area
This area displays the incubator air temperature,
the skin temperature 1, and the skin temperature 2
graphically. However, the skin temperature 1 and
the skin temperature 2 will not be displayed if the
respective skin temperature probes are not
connected. (See “5-5. Graphical Display of the
Incubator Air Temperature and the Skin
Temperature”.)
●Relative humidity & oxygen graph area
This area displays the relative humidity and the
oxygen concentration graphically. However, the
oxygen concentration will not be displayed if the
oxygen supply function is off. (See “6-2.Graphical
Display of the Relative Humidity and/or 8-3.Graphical
Display of Oxygen”.)
●Time area
This area displays the month, the day, the year, the
hour and the minute in this order.

18
4-3-3. Trend 2 Screen
The trend 2 screen displays %SpO2, the pulse rate and the weight graphically. It consists of four areas:
the numerical value area, %SpO2and pulse rate graph area, the weight graph area, and the time area.
＊Settings are not displayed on this screen.
●Numerical value area
Like the trend 1 screen, this area displays the
incubator air temperature, the skin temperatures,
the relative humidity, the oxygen
concentration, %SpO2and the pulse rate.
＊Settings are not displayed in this area.
●%SpO2& pulse rate area
This area displays the %SpO2and the pulse rate
graphically. The vertical axis on the left
shows %SpO2, and the vertical axis on the right shows
the pulse rate per minute. However, %SpO2and the
pulse rate will not be displayed if the probe is not
connected. However, no graph will be displayed if the
probe is not connected, or the main body is not
provided with a pulse oximeter. (See “7-3. Graphical
Display of the Pulse Oximeter”.)
●Weight graph area
This area displays weight readings and a weight graph.
The weight graph is shown in the left area, while the
current weighing mode and the latest reading are
shown in the right area. Recorded readings are
graphically displayed. The scale of the graph changes
depending on the weighing mode and the actual
readings. However, no graph will be displayed if the
measurement section of the weight monitor is not
connected, or the unit is not provided with a weight
monitor. (See “9-6-2. Graphical Display of Weight”.)
The data recorded for the weight graph remains stored even when power is turned off. Be
very careful when you are going to weigh another patient. When weight readings are
recorded, the graph will show the recorded readings. When no readings are recorded, the
graph will remain blank.
