The flexible portions of the fiber optic Light Pipe are designed to be bent, but not
twisted. Twisting, or torque, will decrease the life of the flexible portions, causing
drooping of the Light Pipe and eventual breakage of the fiber optics. As in the illus-
tration, once a section is bent into position A, for example, it must first be returned
to the neutral position before bending into position B. This prevents the twisting motion
of moving directly from A to B that could prove harmful to the unit. For best response,
always position the fiber optic Light Pipe by moving in the same direction as gravity. If
the fiber optic bundle needs to be raised, raise it above the desired position and then
lower to the desired position.

:
Upon manufacture, the Light Pipe is tested to assure maintenance
of position and absence of noise. Over a period of time it is normal for the Light Pipe to
soften and become less obedient. Abnormal softening or occurrence of noise should be
reported to Welch Allyn.

ARNING
:
When pulling out the Light Pipe, push down on the light box to avoid
lifting it off of the mounting plate and possibly dropping it.

Use in place of Model 48200 for neonatal transillumination.
The neonate transilluminator is useful for transilluminating neonates as a means to help
diagnose pneumothorax, locate blood vessels, etc.
This transilluminator includes filters that prevent skin
temperature rise in excess of 39°F (4°C) when
in contact for five minutes or longer.
