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.
2. Remove the unit from the patient area.
3. Using a screwdriver, loosen the single panel fastener that protrudes
from the bottom of the unit. As the screw is loosened, there will be a
 
noticeable "drop" as the front cover is released.
4. Slightly lift the bottom of the front cover toward you and then slide the
 
cover up to remove it.
5. For initial lamp replacement only: Grasp wire clip at top of lamp. Rotate
 
clip toward the base of the unit until it pops out. Discard clip. It was
for shipping purposes only.
6.   Grasp the lamp connector and pull the lamp straight out of its holder.
7. Pull the lamp from its connector and replace it with Welch Allyn
 
Replacement Lamp #04200.
8. Push the lamp back into the holder.
9. Attach the front cover by sliding the tabs at the top of the cover into the
slots at the top of the back housing and then tightening the screw at
the bottom of the unit.
10. Return the unit to the patient area and plug power cord back into
bottom of unit and wall outlet.
 
 
 
 
 
FUSE REPLACEMENT
1. Turn the unit off and remove the power cord from both the wall outlet
and the light box.
2. Press the tabs on both ends of the fuse drawer in and pull the fuse  
drawer out.
3. Remove and replace new fuses of the same type. There is no required  
orientation of the fuses. Be sure to replace both fuses.
4. Reinsert the fuse holder by pressing it into the power connector until it
snaps into place.
5. If the new fuses blow, immediately contact Welch Allyn Technical
Service (315-685-4560).

CLEANING
Focusing Sleeve
For best results, use the disposable sheath model #52640.
1. Remove the focusing sleeve from the Fiberoptic Light Pipe or Fiberoptic
Light Cable by rotating it counterclockwise to unthread.
2. Use a cotton swab soaked in warm water and mild detergent to clean
the distal end of the Fiberoptic Light Pipe or Light Cable, the proximal
side of the Focusing Sleeve (small end), and distal window on the large
end on the Focusing Sleeve.
3. Dry using a new cotton swab.
4. Reassemble the Focusing Sleeve to the Light Pipe or Light Cable by
rotating clockwise.
WARNING: Do not clean any part of the focusing sleeve with alcohol. Clean
only with a mild detergent and water.
NOTE: The focusing sleeve should not be sterilized or immersed.
Fiberoptic Light Pipe, Light Cable, Neonate Light Pipe
For best results, use the disposable sheath model #52640.
