12.2 Maintenance (Operated by professional, the power plug must be pulled off).
12.2.1 Replacement of battery
If the equipment hasn’t been used over six months, start the machine to make it charge
automatically at least 6 hours, insuring the sufficiency of power to alarm for power failure.
The battery could be changed by authorized person only!
In the process of examining the alarm of power failure, if the alarm can not sound, or the sound is too small,
charge the battery up or change a new one in time in case that the battery liquid flow out and damage the parts of the
equipment. If the battery liquid flowed out, must wash it cleanly with the cleanser, so as not to corrode the equipment.
While changing the battery, pull out the plug of supply power firstly, and unload the screws of the operation panel.
Demount the rechargeable battery which lies in the PCB board with electric iron and solder a new one(model:
D80H5A2H) onto the circuit board. Collect them together and dispose them to avoid environment polluting. Don’t
abandon the changed batteries at will.
12.2.2 Replacement of the power fuse
Pull off the power cord, open the fuse socket of the power socket in the back of the warmer, replace it with the
same type of fuse(F 5AL, 5×20). The fuse of the transformer is also in the back of the equipment, replace it with the
same type of fuse(F 1AL, 5×20) and then the replacement is done.

1. Summary
Jaundice is a common phenomenon in neonatal period; it is observed that over 90% newborn babies have
jaundice in different degree. It can be a physiological phenomenon ( called physiological jaundice) in neonatal period,
it also can be an important symptom of many diseases in neonatal period （called pathological jaundice ）. This
pathological jaundice can cause bilirubin brain illness (called kernicterus), it can cause brain damage of newborn
baby, and results in early death and serious sequela, so we must take immediate and efficient measures to treat
neonatal pathological jaundice.
The effect of phototherapy treatment for neonatal high bilirubin blood illness has been approved by clinic, its
principle is that bilirubin can absorb rays to have actinic isomerization, it makes the indirect bilirubin oxidize into one
water-soluble product under the bluish green light (light-oxidation bilirubin ).It fades yellow according to liver and
gallbladder discharging out of body. The medical field recognizes that using phototherapy to treat neonatal
pathological jaundice is a simple and effective method. Neonatal phototherapy unit are also called “infant
phototherapy device” or “blue light lamp”. It is necessary medical equipment of neonatal medical department.
2. Use
This product is used for light treatment to reduce concentration of bilirubin in the body of infants.
