Exam Light II Models 48600 48610 48625 48635 Owners Manual

MOUNTING WALL MOUNTING • Choose appropriate mounting location. • Using mounting plate as template, mark drilling holes as needed for your wall type: Dry wall, paneling, thin plywood or plaster walls less than 1 inch (2.5 cm) thick. Drill four .31 inch (.79 cm) holes, insert hollow metal wall anchors making sure barbs are extended. Concrete block or thick plaster walls greater than 1 inch (2.5 cm) thick. Drill four .25 inch (.64 cm) holes, insert plastic anchors. Metal panel or wood walls greater than 1 inch (2.5 cm) thick. Drill four .31 inch (.79 cm) holes. • Install mounting plate with appropriate screws. When tightened, there will be a gap between the screw heads and surface of the mounting plate. • Mount unit by fitting key hole slots on back of unit over screw heads. • Push unit against wall while pushing down to lock screw heads into small end of key hole slots.

TABLE MOUNTING NOTE: Some table manufacturers supply table mounting hardware for mounting the Exam Light II. Check with your table supplier for availability. • Determine side of table for mounting the Exam Light II. • Trace the outline of the mounting plate and mark the hole locations on a 1.00 inch (2.5 cm) thick piece of wood. • Cut the piece of wood to the outline size and drill four .25 inch (.64 cm) holes. • Using the mounting plate as template, mark the hole locations on the table and drill four .25 inch (.64 cm) holes.

NOTE: Be sure mounting location is at least 10 inches (25.4 cm) below table cushion, and that mounting will not obstruct table interior. • Using four 10-32 x 2 inch (5.08 cm) machine screws with lock washers and nuts, install the block of wood and the mounting plate to the table as shown in diagram. • Mount unit as with wall mounting.

MOUNTING MOBILE MOUNTING • Mount unit by fitting key hole slots on back of unit over screw heads. • Push unit against mounting plate while pushing down to lock screw heads into small end of key hole slots.

SET UP • Carefully remove plastic plug from light pipe holder on top of unit.

Plug

• Insert fiber optic light pipe into light pipe holder until it is secure. • Plug power cord into base of unit and into AC grounded outlet. • Position the power switch located on the top of the unit to ON.

Light Pipe

NOTE: Please refer to use of light pipe section prior to using unit.

Max. 180° To ensure long unit life, high light output and continued position rigidity, we recommend that you do not acutely bend the Light Pipe. For example: Middle Bend-not more than 180°. End Bends- not more than 90° each.

Max. 90°

WARNING: Not for use in the presence of flammable anesthetic. Do not use Model 48200 (Standard model) Light Pipe for neonate transillumination. Even though the distal end of the light pipe does not feel warm to the touch, it can burn neonates. Erythema may result from contact of more than 15 seconds. Use Model 48210 Neonate Transilluminator for safe transillumination.

OPERATION OF LIGHT PIPE 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 illustration, 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.

Position B

SPECIAL NOTE: 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.

WARNING: 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.

NEONATE TRANSILLUMINATOR NO. 48210 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.

NEONATE TRANSILLUMINATOR CAUTION: Use only Welch Allyn Transilluminator No. 48210 for neonatal transillumination.

SET UP AND OPERATION Refer to Set Up page for installation steps.

LAMP REPLACEMENT WARNING: Lamps operate at a high temperature and under pressure may shatter. Do not attempt to replace lamp while hot. Wait until lamp is cool. 1. Turn power switch to “Off” position, unplug cord from outlet and from Light box. 2. Release interlock by sliding interlock arm to left. Pull lamp holder until lamp is fully exposed. (Lamp holder will not slide down if Interlock is not released) Diagram #1. Diagram #1

Diagram #2

Interlock Arm 3. Push release lever down; Diagram #2. Grasp expired lamp by its base and remove from lamp holder. 4. IMPORTANT: Reposition release lever up to original position prior to installing new lamp. Replace only with a Welch Allyn Lamp No. 04200. 5. Visually inspect replacement lamp reflector and bulb, and remove any grease or fingerprints with a clean cloth moistened with alcohol, if required. 6. Slide new lamp into lamp holder socket until it “snaps” into place. Make sure lamp is securely seated to assure maximum light output. 7. Slide lamp holder back into light box. Reengage interlock by moving arm to the right.

WARNING: When sliding the lamp holder back into the light box, hold the light box down to avoid pushing it off of the mounting plate and possibly dropping it. 8. Plug line cord back into unit, and into wall outlet.

CLEANING LENSES • Remove the focusing sleeve from the fiber optic bundle by unthreading counterclockwise. • Use a cotton swab soaked in warm water and mild detergent to clean both the distal end of the fiber optics and the proximal side of the small lens. (See diagram for locations.) • Reassemble focusing sleeve to Light Pipe. • The window may also be cleaned with warm water and mild detergent.

LIGHT PIPE • To maintain unit cleanliness, use disposable Sheath (No. 52640). • May be cleaned with a mild detergent and water solution.

WARNING: Do not clean lens or window with alcohol.

LIGHT BOX Do not Sterilize. Do not Immerse in Cleaning Solutions. 1. Unplug the unit from the wall outlet prior to cleaning. 2. Insert the red plastic plug into the Light Pipe socket prior to cleaning. This will prevent the cleaning solution from getting into the filter inside the unit. 3. Wipe the surfaces of the unit with a cloth dampened in a mild solution of detergent and water. Wipe dry with a clean, dry cloth. 4. The power cord may be wiped clean using the same detergent solution as the box. Care must be taken not to get the plug prongs wet. Wipe dry with a clean, dry cloth. 5. Do not plug the unit back into the wall outlet until it is thoroughly dry.
