I. DESCRIPTION
The NESTOMAT Radiant Warmer provide a controlled source of radiant heat and
illumination. The heat is generated by one 500 watt quartz heat tube located above the
procedure table. The diverging energy emitted from the heating element is reflected
back toward the table surface with a parabolic reflector, this one focuses the diverging
waves of energy into parallel waves which are aimed toward the patient.
A lamphouse contains one standard 20 watt halogen lamp for illumination of the work
area.
I.1 PATIENT BED. POSITIONING OF PATIENT.
The infant should be placed on the procedure table directly on the mattress or with a
single cloth covering between the infant and the mattress cover. The NESTOMAT
Radiant Warmer has capability (ten locked positions) to place the head up or the head
down. Grasp the locking puller and pull outwards. Reposition the table and release
knob. The table will lock in position. Tilting puller is located under the front side of the
table.
The table has hinged, transparent panels on the sides and front wich can be positioned
upright to retain the infant or downward to ease accessibility to the infant. The air
temperature sensor is located at the rear panel.
A space for a X-ray cassette tray is provided at the patient platform; the radiant heater
shroud can be swivelled, during operation, to allow X-ray tratments, just only pushing
the knob located in the rear side of the shroud.
I.2 I.V. STAND.
The I.V. stand is mounted in the accessories rear rail, its height is adjustable.
I.3 OPERATION CONTROLS.
All operation controls are located on the front and the rear of the upper column.

II.OPERATION
IMPORTANT: BEFORE TO USE THE RADIANT WARMER WITH A
PATIENT, IT IS NECCESSARY TO CHECK ITS GOOD PERFORMANCE CONDITIONS,
AS WELL AS THOSE FROM THE ACCESSORIES AND OPTIONS.
II.1 TO OPERATE
To start operation, plug the cord to the mains (check voltage) and press
the I/O switch located at the right side of the trolley.
Press the ON/OFF key at the front panel, the LCD will display "GUIDO
RAYOS X - VER. x.x", immediately afterwards the Radiant warmer will
perform a selftest of all its circuitry.
II.2 TO PREHEAT
CAUTION:BEFORE TO USE THE RADIANT WARMER WITH THE
NEWBORN, PREHEAT THE UNIT FOR A BETTER COMFORT OF THE NEWBORN AND
AN ACCURATE PERFORMANCE. PREHEATING PERIOD OF TIME DEPENDS ON

OPERATION MODE, AIR OR SERVO, CAN BE DIRECTLY SELECTED.
Pressing any key the LCD will display,
AIR=__._ ºC
SELECT MODE
Press the key “PRE” to start the preheating until to reach aproximately
the factory preset temperature (28 ºC). In the meantime the LCD will
display
AT=__._ ºC (__._ ºC)
PREHEATING
After “=“ symbol we can find present temperature.
It is possible to modify preset preheating temperature in order to reach a
nearly temperature of the normal operation temperature. Proceed with
following steps to change preset preheating temperature:
• Turn on the radiant warmer:
