6 Routine Cleaning and Maintenance
6.1 Checking the Light Intensity
It is recommended that the intensity of the light be checked per your hospital
protocol, or at least every six months to ensure proper light intensity. Have a
qualified technician test the intensity level and readjust the intensity
potentiometers to achieve the desired output, if required. Checking intensity
before each use is recommended; however, as LEDs have very gradual
degradation over time, it is not mandatory.
Note: The intensity of the light is not adversely affected if a few LEDs burn
out. The LEDs are installed in groups of six, so failure of a single LED
normally causes six to fail.
Caution: Only qualified personnel should perform service and repair. Use
extreme care when working with exposed circuitry.
6.2 Adjusting the Light Intensity
There are two intensity settings, high and low. The desired setting is selected
using the left rocker switch on the front panel of the light. The light output was
factory calibrated with the neoBLUE
®
Radiometer to provide an initial
intensity of 35 µW/cm
2
/nm at the high setting and 15 µW/cm
2
/nm at the low
setting at a distance of 12 inches (30.5 cm) from the light enclosure to the
baby. The light output can also be adjusted using the two potentiometers
(located on the side of the light enclosure) to accommodate different
distances.
Note: The light will continue to operate with minimal degradation over time.
Timing of potentiometer adjustments is per hospital protocol.
Important! The light was factory calibrated with the neoBLUE
®
Radiometer
to deliver intensive phototherapy at a distance of 12 inches (30.5 cm) from
the baby. Refer to the Service Manual for information on adjusting the
intensity if using the light at other distances, and for information on using
other meters.
6.3 Cleaning
Warning! Disconnect the light from AC power before cleaning.
Remove dust from the exterior of the light with a soft brush or soft cloth
dampened with water. Sponge away remaining debris with a mild solution of
detergent and water, a non-caustic commercial cleaner, or hospital
disinfectant.
Clean the lens with a soft cloth dampened with water. If water alone is
ineffective in removing fingerprints or other markings, use a mild solution of
detergent and water, a non-caustic commercial cleaner, or hospital
disinfectant.
Caution: Observe the following precautions:
