General Information
Incubator/Warmer operating modes
The GiraffeTMOmniBedTM combines the features of an incuba-
tor and a radiant warmer. When used as an incubator, a fan
and heater beneath the bed circulate warm air through the
closed infant compartment. The baby can be accessed
through portholes or doors. When you require even greater
access to the baby, the canopy can be raised and the com-
partment walls can be lowered. As the canopy raises, doors
open to expose a focused radiant heating element inside the
canopy that maintains the baby’s temperature like a warmer.
The OmniBedallows the full range of clinical procedures
without the disruptive intervention of transferring the baby from
one care bed to another.

General Information
Control Modes
The OmniBedhas two control modes when used as either an
incubator or a warmer. With the compartment closed, the
OmniBedcontrols the inside temperature comparing air
temperature readings from the probe on the compartment wall
to a setting you enter using the control panel (air mode) or
from a probe attached to the baby’s skin (baby mode). With
the canopy raised, the OmniBedcontrols radiant heater output
from a heater power percentage setting that you enter using
the control panel (manual mode) or by using temperature
readings from a probe attached to the baby’s skin (baby
mode).
Controls and Displays
The controls and displays, located at the top of the uprights at
the head of the bed, can be divided into two areas: on the left
are the buttons and numeric temperature displays that control
the temperature regulation of the infant, on the right are the
graphics display screen and control knob that control all the
accessory options.Temperatures can be shown in Celsius or
Fahrenheit degrees: the default setting is Celsius.
Temperature Regulation
At start up, the OmniBed prompts you to select one of the
control modes. If the unit was used in the last 2 hours, it will
ask if you would like to retain the settings you used previously.
If you are using the OmniBed as an incubator (canopy closed)-
you select baby or air mode. If you are using the OmniBed as
a warmer (canopy open)- you select baby or manual mode.
If you start with the canopy open, or open the bed during the
first minutes after start up, and you do not select a control
mode, the graphics screen will show the “Warm Up Mode”
message and the radiant heater will automatically run at 100%
power. When ten minutes has elapsed and you still have not
selected a control mode, the graphics display will show the
“Preheat Zone”message and the radiant heater will then run at
the preheat level; the default preheat level setting is 25%
power.

General Information
Alarms
An alarm message appears across the top graphics display
screen identifying the various alarm conditions. In addition, the
alarm light at the top of the control panel housing activates and
an audio alarm sounds.
The audio tone varies with the alarm’s priority: an alternating
two tone alarm indicates a critical alarm that triggers automatic
heater shutdown; an intermittent single tone alarm is used for
other alarms. The alarm light remains on continuously for over
temperature and system failure alarms; it blinks for all other
alarms.
With the exception of the system failure and power failure
alarms, all audio alarms can be silenced by pressing the alarm
silence button located above the graphics screen. At the end of
the alarm silence period the alarm reactivates if the alarm
condition has not been resolved. If two or more alarm condi-
tions occur at the same time, the audio signal for the highest
priority alarm will sound while all the alarm messages will
alternately appear at the top of the graphics screen. If you
select the Help icon during an alarm condition, the description
of that particular alarm will automatically appear on the screen.

High Air Temperature
Active only when the canopy is closed and the unit is in the air
mode, the High Air Temperature alarm triggers when the
temperature measured by the compartment probe exceeds the
air temperature you set previously by more than 1.5°C. The
audio alarm is suspended for ten minutes when you push the
alarm silence button. This alarm usually occurs when you have
just lowered the air set temperature, or when you have
changed from baby to air control mode. Monitor the unit
closely to assure the air temperature decreases.
Low Air Temperature
Active only when the canopy is closed and the unit is in the air
mode, the Low Air Temperature alarm triggers when the
temperature measured by the compartment probe falls more
than 3.0°C below the air temperature you set previously. The
audio alarm is suspended for a ten minute period when you
push the alarm silence button. This alarm usually occurs when
the doors are open without using Air Curtain Boost, when the
canopy has just been lowered, or when both doors are open at
the same time. Monitor the unit closely to assure the air
temperature increases.
Note: The Low Temperature alarm is suspended for 60 minutes
when the unit is first turned on, for 30 minutes after the canopy is
closed, and 15 minutes after the set point is increased.

General Information
Baby Hot - Check Probe 1
Active whenever the unit is in the baby mode, the Baby Hot
alarm activates when the temperature measured by the probe
on the baby skin is 1.0°C above the baby temperature you set
previously (this can be adjusted to 0.5°C using the Setup/
Customize screen). Monitor the patient carefully and check the
attachment of the probe on the baby’s skin. The audio alarm is
suspended for a ten minute period when you push the alarm
silence button. This alarm can also be activated in the Manual
and Air modes. See setup screen.
Baby Cold - Check Probe 1
Active whenever the unit is in the baby mode, the Baby Cold
alarm activates when the temperature measured by the probe
on the baby skin is 1.0°C below the baby temperature you set
previously (this can be adjusted to 0.5°C using the Setup/
Customize screen). Monitor the patient carefully and check the
attachment of the probe on the baby’s skin. The audio alarm is
suspended for a ten minute period when you push the alarm
silence button. This alarm can also be activated in the Manual
and Air modes. See setup screen.
Air Temperature Greater Than... Alarms
These alarms warn of abnormally high temperatures read by
the compartment probe in all control modes and automatically
shut off the heater. They are not self resetting; once the alarms
are activated they must be manually reset by pushing the
alarm silence button, even if the alarm condition is resolved.
Computer independent circuitry continuously measures and
compares the compartment temperature with factory set
levels. Visual and audible alarms are activated and the heater
shuts off if the compartment temperature exceeds these preset
levels, independent of the software.
The functionality of all other alarms is continually checked by
the microprocessor software during normal operation. If a fault
occurs in any of this circuitry, an indicator lights and a tone is
sounded.
Additionally, a computer independent “watchdog”circuit will
reset the computer, turn off the heater, and activate the alarms
in the event of a microprocessor failure or software error.
Air Temperature >38 C
Active only when the canopy is closed and the set temperature
is below 37°C, the Air Temp >38°C alarm activates in the air
mode when temperatures greater than 38°C are read by the
compartment probe. This alarm may occur when you have just
lowered the air set temperature, or when you have changed
from baby to air control mode. Monitor the unit closely to
assure the air temperature decreases.
