GENERAL WARNINGS

• The user should carefully study the Operation and Service Manual before using the equipment in a clinical environment. Instructions should be followed, with special attention given to warnings, controls and user specifications. The Manual should be available to the appropriate personnel. •This Manual contains information about the proper procedures for preparing this product for its use and care. • Before every procedure, carefully inspect the light source to ensure it has been properly maintained and cleaned, and that it is fully functional. DO NOT use if inspection reveals any damage such as case damage or loose connectors. • Follow the instructions of other manufacturer’s equipment when used in conjunction with this product. • To reduce the risk of fire and electric shock, do not expose electrical equipment to moisture. When cleaning, do not immerse any electrical device in liquid. •Do not use or store liquids on or above the light source. • SAFETY PRECAUTIONS MUST ALWAYS BE EXERCISED WHEN USING ELECTRICAL EQUIPMENT TO PREVENT OPERATOR/PATIENT SHOCK, FIRE HAZARD OR EQUIPMENT DAMAGE. • Electric shock hazard. If unit is not functioning properly, DO NOT OPEN. Please refer to the Repair and Return Section of this Manual. • All electrical equipment must be used with approved hospital grade power cords and power plugs inserted properly into grounded AC power outlets. • The light source should never be used in ocular surgery or in a surgical procedure requiring direct illumination of the eye. • Use care not to point any fiber optic cable directly at the eye while operating the light source. • The light source produces high intensity light. Thermal burns can result from improper use of the light source or from the light output of the fiber optic cable.

• Explosion Hazard. Do not use in the presence of flammable anesthetics, liquids, vapors, gases or dusts. • Keep cooling vent and fans free of obstructions. • FIRE HAZARD: DO NOT DRAPE OR COVER THE LIGHT SOURCE WHILE IT IS OPERATING. • When light source is not in use, turn off the power or put the unit in stand-by mode. • Ensure that the fiber optic cable matches the port type to prevent damaging the optical components of the light source. For user convenience, the light source has a turret with labeled selectable ports. • Do not use the headlight at distances of less than 10” (25cm).

precautions • Take precautions to verify that the fiber optic cable is appropriately suited for the light source. Xenon and other high illumination light sources. require premium fiber optic cables in order to achieve optimal performance and prevent damage to the fibers, thereby diminishing the quality of the light output or the useful life of fiber optic cable. • Take precautions not to touch or disconnect the cable end fitting from the turret until the Light Source has been “shut down” for a period of time and allowed to cool. The cable end fitting will remain hot immediately following shut down, which can cause burns. • Take precautions to not place and rest a hot cable end fitting and/or head light on a patient or allow the system to come in contact with un-protected hands or tissue. The entire system should be allowed to cool following use. Failure to do so can cause burns and/or tissue damage.

OVERVIEW The MLX light source delivers 300 spare watts of cool white infrared (IR) filtered light. The lamp is housed in a lamp module that can be easily serviced without special tools. Set Up and Inspection Before Use The light source comes with the hospital grade power cord packaged separately. Verify that both components are in good condition. Before turning power on to the light source, make sure the unit is plugged into any standard 100VAC to 240VAC 4763Hz (as appropriate) outlet. Grounding reliability is guaranteed only when connected to a “hospital grade” receptacle. Allow a minimum of 2 inches (5.08 cm) clearance at the rear and sides of the unit for cooling air flow. Ensure that the unit is not near air exhaust or against other equipment. WARNING: The MLX light source monitors air intake temperature and will turn off if ambient temperature is > 40O C

OPERATION

1. Insert a fiber optic cable in the proper port in the turret. The active port is indicated by a on (See Figure 1). Available ports are ACMI, Olympus, Storz and Wolf cable-compatible. All ports appropriately.

the front panel are identified

2. Press the Power Switch in the upper left corner of the front panel (See Figure 2). 3. When the Power Switch is pressed the Stand-by Light (Figure 2) will blink and there will be a 3 – 4 second delay before the Xenon Lamp illuminates while the system does a self-diagnostic check. 4. Press the Stand-by Button.

OPERATION

5. The system will start up at the same light intensity as when last used (Figure 3). For new systems, the light intensity will start at the minimum 20% setting. 6.To adjust the light intensity, push the Membrane Switches (Figure 3): + to increase or - to decrease the light output or intensity. Range is 0%, 20 – 100% in 5% increments. Holding the + or – button will change the intensity more quickly. NOTE: It is strongly recommended that the light be used at the minimum intensity for good visualization. 7. The System Status Display can be pressed to show both lamp time and system operation time. A second press of the switch will show the software version of the system monitor. A third press returns to light output. (The system will automatically return to the light intensity reading after15 seconds). 8. The system can be placed in stand-by mode (no light emitted) allowing the surgeon to unplug a headlight and move around the table, or to change cables in a laparoscopic or endoscopic procedure. CAUTION: Cable end fitting can be HOT!!! NOTE: If unit is left in stand-by mode for 15 minutes, it will automatically shut off the lamp. Fans will keep running. To re-activate, push the Stand-by Button. 9. To shut the system off, simply press the main Power Switch as in Step 2.
