This manual describes the setup, installation, start-up, and use of the Welch Allyn Light Source.
Use of the Welch Allyn Light Source is indicated for medical lighting applications requiring a remotely located, high-quality white light. This product must only be used by qualified medical personnel.
The use of the Welch Allyn Light Source is contraindicated for applications where high intensity light might burn or damage tissues; such as for neonate transillumination and ophthalmic procedures.
For further contraindications, the user must also consult the operating manual of the instrument being used with the Light Source in the medical procedure.
This product must only be used by qualified medical personnel.

Chapter 1 Introduction |
Welch Allyn Light Source |
A warning statement in this manual identifies a condition or practice which, if not corrected or discontinued immediately, could lead to patient injury, illness or death.
WARNING RISK OF FIRE. Do not operate on, near, or over combustible material. Operate only on smooth, hard, flat surface. This device is not suitable for use in
the presence of a flammable anesthetic mixture with air or oxygen or nitrous oxide. An explosion may result.
WARNING The high intensity light at the front of the light source and at the tip of the fiber optic bundle will create high temperatures and bright light. To minimize the risk of injury, avoid direct viewing or contact with sensitive tissues.
WARNING Do not use for neonate transillumination.
Erythema may result.
WARNING To prevent temporary blinding, always plug the fiber optic bundle into the Welch Allyn Light Source and set the light intensity control to minimum before turning the power ON.
WARNING If this light source is used during invasive surgery, the failure of a component within the system, causing loss of illumination, may indirectly cause risk to the patient. Therefore, it is recommended to have alternative means of illumination available.
WARNING When the unit is on, never disconnect the fiber optic bundle from the light source or the accessory from the end of the fiber bundle. High intensity light from the end of the fiber optic bundle can ignite combustible material.
Directions for Use |
Chapter 1 Introduction |

WARNING PROVIDE ADEQUATE VENTILATION TO PREVENT OVERHEATING. Do not cover or drape this light source. Provide a 3 inch (7.62 cm) distance between the Welch Allyn Light Source and any solid objects.
WARNING Use only non-electrically conductive fiber bundles. Use of conductive fiber bundles will
compromise the safety and effectiveness of this device.
WARNING RISK OF SHOCK. Do not operate the Light Source without a lamp installed. Disconnect power before attempting to change the lamp.
WARNING This product comes with a power cord that is intended for use only with this product. The power cord has not been tested and approved for use with other products that may have the same power connectors. If you cannot locate the original power cord, please contact Welch Allyn to obtain replacement parts.

A caution statement in this manual identifies a condition or practice which, if not corrected or discontinued immediately, could lead to equipment failure, equipment damage, or data loss.
Caution United States federal law restricts this device to sale by or on the order of a health care practitioner.
Caution Allow the lamp to cool before replacing.
Caution Since the Solarc Light Source uses a custom lamp, always have a spare lamp available for replacement. USE CAUTION BECAUSE LAMP MAY BE HOT. Allow lamp to cool before replacing.
Caution Do not sterilize the Welch Allyn Light Source. Refer to Cleaning section for cleaning instructions.
Caution Do not switch the Welch Allyn Light Source ON and OFF in rapid succession. Doing so will dramatically shorten lamp life. Allow lamp to cool down 10 to 15 seconds between uses.
Caution Do not use or store liquids above or on the
Welch Allyn Light Source.
Caution Do not operate device without the cover in place. Operate in the horizontal orientation only.
Caution Only qualified medical personnel should operate the Light Source.
Caution System integrator is responsible for all safety testing, including optical and thermal testing.

|
Operation |
|
|
|
The Welch Allyn Solarc Light Source is used to supply high quality, white light for video and optical illumination systems.
1.Verify the power switch is in the OFF position ( ). Place the light source on a smooth, hard, level surface with at least 3” air clearance between the light source and any solid objects. Plug the power supply outlet connector to the light source power input (see Figure 1) and then plug the power supply into an appropriately rated power outlet (refer to Section 4, Electrical Specifications).
2.Turn the light intensity control knob to the minimum position (see Figure 1). Plug the fiber optic bundle into the light port and connect the distal end to the instrument.
Note For proper lamp performance, verify the fiber optic bundle is plugged in at all times.
3.Turn the power switch to the ON position ().The lamp will take 10 - 15 seconds to complete the warm-up cycle.
4.Set the light intensity knob to the desired level (see Figure 1).
5.Turn the unit OFF when not in use.

Chapter 2 System Description and Operation |
Welch Allyn Light Source |
.
Caution Do not restart the Solarc Light Source immediately after shutting it off - it may fail to light. If this occurs, turn the power off and wait 10 to 15 seconds before turning the unit back on.
In dental applications, the optional filter blocks light wavelengths that cure some dental composites. For white light, switch the filter out of the light path. When working with dental composites, switch the filter into the light path (Figure 1).
Note It is recommended to test dental composites with and without the optional filter prior to use with a patient.

aField strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the Welch Allyn Light Source is used exceeds the applicable RF compliance level above, the Welch Allyn Light Source should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the Welch Allyn Light Source.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m) can be estimated using the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.
Note 1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects, and people.
