1.0 Purpose and Features

1.1 Purpose

The headlight is used for examination, diagnostics and surgical operations for multifarious uses including microsurgery.

1.2 Features

• 50,000 hours of LED life provides for a maintenance free device with an end life of approximately 20 years.
• The unit has infinite mobility, not confined by access to power sockets, and its charge will last more than 4 hours at full intensity.
• Its light beam is extremely homogeneous and free of imperfections.
• Its high CRI rating of 95 is very desirable in color-critical applications such as neonatal care, medicine and surgery, as it shows the true colors of tissues and skin, thereby reducing the time to diagnosis and surgery.
• The light-weight battery packs have a retention clip to be used on the user's belt or pocket.
• The wall mounted Battery Charger comes with a Charge Monitor that alerts the operator when the Battery is fully charged.

3.0 SPECIFICATIONS

4.0 OPERATING INSTRUCTIONS

4.1 Charging the Battery

1. Plug the charger male connector into the receptacle on the Control Unit.
2. Plug the AC connection into a 100-240 VAC source.
3. The charger indicator light will illuminate red while charging and turn green when charging is complete (approximately 3.6 hours).
4. An 85% partial charge may be performed in 2 hours.
5. Disconnect the charger from the AC source and unplug the charger from the control unit.

4.2 Illuminator and Headband Operation

1. The illuminator unit comes with an integral pendant cable assembly.
2. The cable should be routed and snapped into place through a set of two cable clips. For dual ratchet headsets one is located on the top on the crown and one on the rear of the headband. The user has the choice of using the set on the left or the right.
3. For softband/velcro headsets, the cable should be routed through two clips along the circumference.
4. The illumination spot size may be adjusted by turning the grooved dial on the headlight.
5. The linkage assembly on the headband allows for personal positioning control. The joystick is used to further adjust the position of the light beam.

4.3 Control Unit / Battery Pack Operation

1. Assure the pendant Cable Assembly is plugged into the Control Unit/Battery pack receptacle. There are red orientation dots that must be aligned.
2. Clip the control unit where desired or place in a pocket.
3. Turn the ON/OFF and intensity control knob clockwise to turn unit On (switch will close). This knob also controls the intensity.
4. To turn unit Off, turn control knob counter-clockwise until switch opens.
5. When battery has discharged to a level too low to maintain operation, the Illuminator will dim or flicker and the green LED on the control panel will turn off.
6. The unit's operational time could be extended from 4½ hours at full intensity to greater than 9 hours by using the illuminator at half intensity.

5.0 CARE & MAINTENANCE

DO NOT AUTOCLAVE !

5.1 Headlight, Headgear and Cable

Exterior surfaces of headlight, headgear and cable can be wiped clean with any of these solutions:

• Banicide
• Cidex, Cidex Plus, Cidex 7
• Metracide
• 10% Wescodyne
• 10% bleach
• 70% isopropyl alcohol
• Wavecide-01
• Mild soap

Headbands and headlight modules can not be immersed into disinfecting liquids or sterilizers. Keep ends of cable clean by wiping with a damp cloth. Allow to dry before use. Clean the optics only with lens tissue available at any camera store. Follow the instructions on the package. To insure long life for the headgear, cable and power source, store them in a cool dry environment.

5.2 Joystick

Joystick can be sterilized after unscrewing from headlight.

DO NOT AUTOCLAVE ANY OTHER PARTS OF THE HEADLIGHT SYSTEM !

6.0 WARNINGS AND CAUTIONS

6.1 Warnings

Users of this headlight should be trained in the appropriate surgical procedures. They should read and understand the owner's manuals for this Headlight and all equipment used in conjunction with it.

6.2 Cautions

• [caution-icon] Do not look directly into headlight when illuminated. Eye injury may result.
• [caution-icon] Do not use at distances closer than 10in(25cm) for extended periods. Erythema may result.
• [caution-icon] Service must be performed only by ISOLUX authorized repair personnel.

7.0 The ISOLUX ADVANTAGE: A word about Color Rendition Index (CRI)

The color rendering index (CRI), with a scale from 0 to 100 %, is a quantitative measure of the ability of a light source to reveal the colors of various objects faithfully in comparison with an ideal or natural light source like the light from the sun. Light sources with a high CRI are desirable in color-critical applications such as neonatal care, medicine and surgery, as it shows the true colors of tissues and skin, thereby reducing the time to diagnosis and surgery. The IsoLED unit has a high CRI of 95, which brings it close to the optimum value of 100, and is one of the few units in the global market with this specification.
