CONTROL BODY
Suction Valve – Depress to aspirate fluids or air through the biopsy/suction channel.
Air/Water Valve – Covering the vent hole in the top of the valve delivers pressurized air
through the air nozzle in the distal tip. Covering the hole and fully depressing the valve
delivers pressurized water through the water nozzle in the distal tip.
Biopsy Seal – Allows passage of accessories while preventing escape of fluids and air.
Biopsy Port – For introduction of biopsy forceps and other accessories.
Up/Down Deflection Control Knob – Rotation of the knob toward the operator will deflect
the bending section up. Rotation away will deflect the bending section down.
Right/Left Deflection Control Knob – Rotation of the knob toward the operator will
deflect bending section left. Rotation away will deflect the bending section right.
Up/Down Deflection Lock – When this lever is in the “F” (Free) position (rotated fully clock-
wise) the bending section moves freely. When the brake lever is rotated counterclockwise,
deflection of the bending section becomes progressively more stabilized. When the lever is
rotated fully counterclockwise, the bending section is locked into position. Note that when the
lock is engaged, deflection can still be accomplished by rotating the deflection lever.
Right/Left Deflection Lock – Function similarly to Up/Down lock.
ELECTRONIC FUNCTION CONTROLS (when connected to video printer with built-in memory).
F (Freeze) Button – Push to freeze an image.
C (Copy) Button – Push to activate the remote video printer.

“live” image.
INSERTION TUBE – Contains random light guides, biopsy/suction channel, air and water
lines, steering cables and wires from CCD (Charge Coupled Device).
BENDING SECTION – Contains articulating vertebra that allows deflection in two planes.
DISTAL TIP
Air Nozzle – Directs pressurized air across objective lens to remove moisture and to
distend cavity being examined.
Light Guides – Provide illumination of examination area.
Biopsy/Suction Channel – Opening from which biopsy forceps and other accessories exit
and where fluid/debris is aspirated when the suction valve is depressed.
Objective Lens – Contains the lens system that provides depth of field and field of view.
Water Nozzle – Directs pressurized water, via the water nozzle, across objective lens to
remove debris.
ENDOSCOPE CONNECTOR TERMINAL
Air/Water Input Ports – Couples with the air/water bottle to allow the introduction of
pressurized air and water to the instrument.

Preparation and Inspection for Use
Prior to Initial Use
Before preparation or set up of the equipment, check all components received against
the list of components (see components section) to verify a complete set. If parts are
missing, please notify Welch Allyn. Review the nomenclature, set-up, operation, and
cleaning/disinfection sections to become familiar with the equipment.
Specifically, inspect:
Video Endoscope
Insertion Tube – for tears, cuts, dents, bubbles, bumps
Control Section – depress valves and test bending section deflection to assure smooth
rotation of controls.
Biopsy Port – pass cleaning brush through biopsy/suction channel to verify
smooth passage
Leak Test – the watertight integrity of the instrument should be verified following the
procedures outlined on page 25.
Light Source
Cabinet – for any dents, scratches or other abnormalities
Water Bottle – for any cracks, leaks, etc.
System Set-up
NOTE: The instrument should be cleaned and disinfected prior to initial
use, following the steps starting on page 23 and 29.
1. Connect the power cord to the power cord receptacle on the back of the light source.
2. Plug the remaining end of the power cord into a properly grounded 100-240 volt AC
outlet.
3. Fill the water bottle to the fill line with clean, distilled water and replace the sealing cap.

Preparation and Inspection for Use (continued)
4. Plug the endoscope connector terminal into the
endoscope connector port of the light source.
The endoscope connector terminal should fully
engage and “click” into place.
5. Plug the water bottle into the
recessed area on the front panel
of the light source. This will couple
the water bottle both to the light
source air output port and the
VideoSigmoidoscope connector
terminal air/water input ports.
6. Activate the Power switch on the
front panel. The green Lamp
Ignition/Stand-By light will blink for
approximately 11 seconds. Once the
LED stops blinking, the lamps are
ready to be ignited.
7. Once the green Lamp Ignition/Standby light remains
lit, press the Lamp Ignition Switch. The lamps will
ignite and the Lamp Ignition/Standby light will go
out. The lamps require 11 seconds to warm up. This
length of time will be indicated by the center LED of
the Picture Brightness Indicator, which blinks until
the lamps reach full intensity. Once the Picture
Brightness Indicator remains constant, the lamps are
fully warmed up, and the system is ready for use.
NOTE
: If the Light Source is powered up without having the Video-
Endoscope attached, the lamp ignition Standby LED will remain
blinking and lamp ignition cannot occur.
WARNING: Once lamps have been lit, do not remove the instrument
from the light source without turning the main power switch off or putting
the lamps on Stand-By by pressing the Lamp Ignition switch. If the
VideoEndoscope is removed from the light source, avoid looking
directly into the intense light provided by the light source to prevent
damage to your eyes.

8. Activate the Air switch to verify function of the pump. Air should begin to flow immediately
out of the top hole in the air/water valve on the control section of the instrument.
WARNING: It is essential that the instruction manual for the VLX-20 Light
Source be reviewed in detail prior to using the system.
Physical System Inspection
Before inspecting the system, the VideoEndoscope should be tested to verify that it is watertight. Refer to the Leak Test procedures on page 25.
The following steps should be repeated prior to every procedure to verify that the system is
working properly. If any problem is encountered, immediately consult the troubleshooting section of this manual or contact Welch Allyn Customer Service (1-800-535-6663) for assistance.
Insertion Tube, Umbilical Tube, and Bending Section
N
OTE: The insertion tube may have a slight curve when first removed
from the package due to product settling. This can be eliminated by
storing the instrument with the insertion tube in a straight position.
1. Inspect the insertion tube and bending section for tears, cuts, dents, bubbles, bumps or
other abnormalities on the surface.
2. Run your fingers carefully over the entire length of the insertion tube and bending section
to check for protruding braid.
3. Inspect the umbilical cord for outward indications of damage (e.g., dents, cuts).
CAUTION: To avoid harm to the patient and further damage to the equipment, Do Not use a VideoEndoscope with outward signs of damage.
NOTE
: Make sure the distal end of the instrument is not damaged. The
distal end has an atraumatic non-removable tip. Do Not try to
remove the distal tip. Doing so will result in damage to the distal
portion of the instrument.
12 VideoPath
Preparation and Inspection for Use (continued)
CAUTION: Do Not wind the insertion
tube into a tight radius. Serious
internal damage could result. Proper
storage procedures are outlined
on page 39.
Deflection Controls
1. Rotate the up/down and right/left deflection
control knobs to the limit in each direction.
The knobs should rotate without excess
friction or grinding.
NOTE
: Do Not attempt to rotate the deflection
knobs past their limits. This can result
in severe damage to the steering
mechanism.
2. Make sure the bending section can be
locked into position by engaging the deflection brakes. The brakes are disengaged
when the brake levers are rotated fully clockwise (looking at the steering knobs straight
on). The bending section will move freely. As the brake levers are rotated counterclockwise, the bending section becomes progressively stiffer. When the brake levers are
rotated fully counterclockwise, the bending section is locked into position.
CAUTION: Do Not deflect the bending
section of the VideoEndoscope by
hand. This applies excess force to the
deflection mechanism and may result
in steering cable failure. If the deflection controls do not operate smoothly
do not use the VideoEndoscope. Doing
so may result in injury to the patient or
further damage to the instrument.
Inspection of Light Guides and Optics
1. With the lamps on, hold the distal tip approximately
40mm from any surface.
2. Verify light is being emitted from both light guides.
