Function processes and alarms
Heating-up
After switch-on with button (2) the device starts heating. The desired radiation intensity can be selected with
knob (13) and is indicated as LED spot in display (12). Depending on the selection and the ambient
temperature the heating-up time will be between 3 and 15 minutes.
Normal operation up to 10 mW/cm²
Radiation intensity up to 10 mW/cm² cannot cause any problems and under normal conditions it is sufficient
to maintain the body temperature of healthy normal-weight infants.
Increasing the radiation intensity
By turning the knob (13) clockwise the radiation intensity is increased. Each selection increment is confirmed
by a short tone. The intensity selection is indicated as LED spot in display (12).
Maximum intensity
Depending on the device model and the calibrated distance to the patient pad a maximum intensity of 14 to
30 mW/cm² can be selected. In case of a selection which the radiant warmer is unable to reach, the
maximum intensity is indicated by a permanent LED spot in the intensity selection display (12). The un-
reachable selection is indicated by a flashing LED spot.
Operation above 10 mW/cm² with safety function
Under certain circumstances radiation intensity above 10 mW/cm² may bring an infant in a hyperthermic
condition. An intensity selection above 10 mW/cm² is indicated by warning lamp (10). After 15 minutes the
intensity is automatically reduced to 10 mW/cm². When the high intensity shall be continued, this must be
confirmed by pushbutton (4).
Alarm:
In the intensity selection display (12) the LED spot for the selection and the LED spot for 10 mW/cm² flash
alternately and a short alarm tone sounds in intervals of 2 seconds. The alarm can be reset for 15 minutes
by pushbutton (4). Now the radiant warmer will emit the selected intensity for further 15 minutes. The yellow
warning lamp (10) lights and indicates that the safety function >10 mW/cm² is activated.
Operation above 10 mW/cm² without safety function
Provided that the patient's temperature is surveyed, the safety function can be switched-off temporarily by
pushing the button (4) for approx. 3 seconds. A special warning is expressed regarding the danger of
hyperthermia in case of operation at an intensity above 10 mW/cm²!
Alarm:
The switch-off of the safety function with button (4) is confirmed by two short tones and the warning lamp
(10) flashes.
The reactivation with button (4) is confirmed by one short tone. The warning lamp (10) lights in case of an
intensity selection above 10 mW/cm².
When the radiant warmer is switched-on anew, the safety function is always activated.
Reducing the radiation intensity
By turning the knob (13) anti-clockwise the radiation intensity is reduced. Each selection increment is
confirmed by a short tone. The intensity selection is indicated as LED spot in display (12). Depending on the
amount of intensity reduction the cooling-off will take 1 to 4 minutes.
End of operation
Switch-off the heating with button (2). The pilot lamp for the safety cut-off at the bottom side of the device
lights.
