SYMBOL DESCRIPTIONS
Attention: Consult user’s manual for additional information.
WARNING: Do not perform neonatal trans-illumination without the
use of the #48210 neonatal trans-illuminator (with U.V. filter). Do not
remove the focusing sleeve from the light pipe and use the light pipe
for trans-illumination. Severe burns may result.
General practices to minimize risk of harm to the skin from optical
radiation hazards include: minimizing illumination intensity at the tissue examination site, minimizing exposure times, and taking additional precautions when skin sensitivity has been altered through
tissue trauma or the use of anesthesia.
General good practices to minimize risk of harm to the eyes from
optical radiation hazards include: avoid looking at bright light sources
and their reflections, and protect eyes where normal pupil sizes and
aversion responses are not present.
There are no user serviceable/replaceable parts other than lamp and
fuses. Please refer any other service to qualified and authorized
service centers.

MOUNTING
Use one of the following three mounting options in order to ensure proper
operation of the light box.
Wall Mount
Choose appropriate mounting location. The length of the light pipe is 4 feet
totally extended (fiberoptic light cable is 7.5 feet). When choosing a mounting
location, keep these dimensions in mind in addition to accounting for the
actual application the light will be used for and what portion of the
examination table will need to be accessed.
1. Using the mounting plate as a template, mark drilling holes as needed
(depending on your wall type).
2. Dry Wall, Paneling, Plywood or Plaster
(1/8 inch (.3 cm) to 5/8 inch (1.6 cm)
thick) - drill four (4) 3/8 inch (1cm) holes,
insert hollow metal wall anchor
assembly.
3. Concrete Block - drill four (4) 3/16 inch
(.5 cm) holes, insert plastic anchors. Use #8 x 1/2 inch screws to
secure.
4. Metal Panel or Plywood walls greater than 5/8 inch (1.60 cm) thick drill four (4) 1/8 inch (.3 cm) holes. Use #8 x 1 inch screws to secure.
5. Once holes are drilled, install the mounting plate with the appropriate
screws. Completely tighten the screw so there is no gap between the
screw head and the mounting plate.
6. Mount the Light Box to the plate by inserting the pins on the back of the
light box into the slots on the mounting plate. Let the light box drop
down to position the pins into the narrow portion of the mounting slots
.
7. To secure the Light Box to the plate, insert two (2) .50” (1.27cm) screws
through the bottom of the mounting plate and tighten into the bottom
of the Light Box using a phillips head screwdriver
.
5. To secure the Light Box to the mounting plate, insert two (2) .50” (1.27
cm) screws through the bottom of the mounting plate and tighten into
the bottom of the Light Box using a Phillips head screwdriver.
NOTE: Some tables require additional reinforcement of the mounting bracket
to support the mounted light. In this case, we recommend using a 1” (2.5 cm)
thick piece of plywood. When employing this reinforcement to the bracket,
please follow instructions 6 - 11 below.
6. Trace the outline of the mounting plate and mark the hole locations on
a 3/4 inch (1.9cm) thick piece of plywood.
Warning: Risk of fire. Replace fuses as marked.
Caution: High Temperatures
Caution: High Intensity Light

cm) below the table top cushion and that the mounting position will not
interfere with the operation of the table.
2. Using the mounting plate as a template, mark the hole locations on the
table and drill four (4) .25 inch (.64 cm) holes in the table.
3. Using four 8-32 screws with lock washers and nuts, install the
mounting plate to the table as shown in the diagram.
4. Mount the light box to the plate by inserting the pins on the back of the
light box into the slots on the mounting plate. Let the light box drop
down to position the pins into the narrow portion of the mounting slots.

SET-UP AND OPERATION
Set Up
1. Secure the Light Box to one of the mounting options per the appropriate
instructions.
2. Insert the Fiberoptic Light Pipe, Fiberoptic Light Cable, or Neonate Light
Pipe into the light pipe receptacle on the top of the Light Box.
3. Plug the power cord into the base of the Light Box and the remaining
end into a grounded AC outlet.
4. Toggle the light switch to the “ON” position to operate.
NOTE: Remember that the Fiberoptic Light Pipe, Fiberoptic Light Cable, and
Neonate Light Pipe contain several thousand individual optical fibers,
therefore appropriate handling is required to ensure long fiber life. Do not
bend the flexible portions of the light pipe at acute angles as this will break
individual fibers and reduce light transmission. For example, do not bend the
semi-flexible middle portion of the Fiberoptic Light Pipe more than 180
degrees and do not bend the proximal and distal sections more than 90
degrees. Be careful not to pull on the Fiberoptic Light Cable as this may cause
fibers to break.
Operation Of Light Pipe
The flexible portions of the Fiberoptic Light Pipe are designed to be
articulated, but not twisted. Twisting or applying torque to the flexible
sections will greatly decrease the life of the Light Pipe. This type of
movement will cause premature drooping of the Light Pipe (will not stay in
place once positioned) and eventually will result in breakage of the fiberoptic
bundle. For best results, always position the Light Pipe by moving it in the
same direction as gravity. For example, if the pipe needs to be raised, raise it
above the desired position and then lower it into place.
NOTE: Upon manufacture, the Light Pipe is tested to assure maintenance of
positioning and to verify the absence of noise upon articulation. Over a period
of time and use, it is normal for the Light Pipe positioning capability to reduce
and soften becoming less obedient. Abnormal softening or occurrence of
noise upon articulation should be reported to Welch Allyn Technical Service
(315-685-4560) immediately.
Operation of Focusing Sleeve
The focusing sleeve at the end of the Fiberoptic Light Pipe and Fiberoptic
Light Cable provides adjustment of the illumination spot size. Twisting the
knurled portion of the focusing sleeve in a clockwise direction will make the
spot smaller. Twisting the knurled portion of the focusing sleeve in a
counterclockwise direction will increase the spot size.
LAMP REPLACEMENT
CAUTION: Lamp may be hot. Allow the lamp to cool before replacing.
1. Turn the unit off and unplug the power cord from both the wall outlet
and the Light Box.
