[4] Heat Control
Heater output of the unit can be controlled in two user-selectable modes. In the Manual Control mode, the heater
output is set to a fixed level (%); in the Servo Control mode, a skin temperature probe is attached to the infant and
the heater output is automatically controlled to maintain the infant's skin temperature at a preselected level.
4-1. Setting the Heater Output (Manual Control)
Heater output can be controlled as you like. Change it as
necessary to warm the infant speedily or slowly.

Monitor the infant's temperature continuously on the skin temperature display. Pay special
attention to the fluctuations in the skin temperature.
If too much heat is supplied from the start, the infant's skin temperature may rise above a target
level. Heater output should be increased gradually while monitoring the infant's skin temperature carefully. Avoid rapid heating.
When it is desired to maintain the infant's skin temperature at a target level, the Servo-control
mode of operation is recommended.

■ When the heater output is set to 30% or higher in
Manual Control operation, the baby check alarm indicator will flash and an audible alarm will sound every
15 minutes of operation, and the heater power will be
shut off. If the silence switch is pressed, the audible
alarm will be silenced.
4-1-2. Skin temperature monitoring
To monitor the infant's skin temperature continuously on
the control panel of the Infa Warmer, attach the skin temperature probe to the infant.
（1）Before attaching the skin temperature probe to the
infant, clean the site of attachment with alcohol or
lukewarm water to get rid of any fetal fat or dirt.
（2）Attach the skin temperature probe to a site between
the navel and the xiphoid process on the infant's abdominal median line using the "cover baby". Affix a
piece of tape at a little distance from the tip of the
probe to fix the probe securely to the skin.
An optional minimum-size skin temperature probe
is recommended for a very small infant or depending on the site of attachment.

Follow the doctor's instructions as to where
to attach the skin temperature probe to an infant in a prone position.
Resin
The skin temperature probe is for monitoring the infant's skin temperature and does not
monitor the core temperature. Check the
infant's temperature status regularly, especially for signs of fever or hypothermia.
Metal
Skin
Do not place the skin temperature probe
under the infant.
Do not use it as a rectal probe.
（3）Insert the cable plug of the skin temperature probe
firmly into the skin temperature probe connecting
jack on the control panel. The temperature detected
by the skin temperature probe will be displayed on
the skin temperature display.
If a disposable skin temperature probe is used, insert
the plug of the connecting cable firmly into the skin
temperature probe jack, and connect the connector of
the connecting cable of the disposable skin temperature probe to the connector on the other end.

（4）Allow 4-5 minutes after attaching the skin temperature probe for the infant's skin temperature on the
display to stabilize before starting skin temperature
monitoring.
Temperature can be displayed either in Centigrade
(℃) or in Fahrenheit (°F). To change the display
unit from one to the other, use the ℃/°F selector
switch.
The infant's skin temperature is displayed in the
range of 30.0-42.0℃ in 0.1 ℃ increments. "Lo" will
be displayed if it is below 30.0℃; "HI" will be displayed if it is above 42.0℃.
If the thermistor of the skin temperature probe is attached improperly to the infant, or if it should
be dislodged accidentally from the infant, the skin temperature cannot be detected accurately. In
Servo Control operation, in particular, be very careful not to heat the infant unnecessarily.

4-2. Setting the Skin Temperature (Servo Control)
The Servo Control system controls the heater output by giving priority to the maintenance of the infant's skin
temperature. It detects the infant's skin temperature with a skin temperature probe attached to the infant's
abdomen and maintains an optimum thermal environment through feed back control. In the Servo Control
mode, the heater output is controlled automatically to maintain the infant's skin temperature at a constant level
(i.e. set temperature); if the infant's skin temperature is lower than the set temperature, the heater output will
rise, while if the infant's skin temperature is higher than the set temperature, the heater output will fall.
After attaching the skin temperature probe to the infant, check that the infant's skin temperature displayed on
the skin temperature display is stable.
（1）Attach the skin temperature probe to the infant. After the skin temperature has stabilized, press the
˚C
Servo Control switch for one second.

Attach the skin temperature probe securely to the infant's abdominal wall. The skin temperature cannot be detected accurately if the skin temperature probe should be dislodged
accidentally from the infant's abdominal wall, or otherwise become attached improperly to
the infant's abdominal wall. The skin temperature cannot be detected accurately if the skin
temperature probe should be warmed by being covered with a blanket, diapers or the infant's
arm, or if it should be cooled by getting wet with the infant's urine or some medical fluid.
If the infant should produce heat spontaneously or should have developed a fever, the heater
output may drop and/or some other adverse effects may result.
