Instrument Function This device offers binocular (both eyes) viewing, providing a threedimensional stereoscopic view. This stereoscopic view is then magnified and illuminated to provide excellent tissue rendition.
Portable Binocular Microscope When the binoculars are engaged, the visual pathways are displaced medially to allow for binocular vision in narrow cavities. Two diopters (1.5x) magnification improves vision. When the binoculars are rotated upwards, the scope becomes a convenient basic headlight.
Flat Surface Magnifier l
The three diopter (2.5x) flat surface magnifier is available in either the headband model or the spectacle model. The magnifier can be flipped up for convenient headlight use.

CAUTION: DO NOT look directly into the light. This device contains a High Intensity Lamp. It is not to be used for illumination or examination of any portion of the eye, Posterior or Anterior.

Optics Assembly l
l
The optics assembly can be adjusted to the desired position by manipulating the links in the pivot mechanism. The Optics Assembly should be positioned as close to the eyes as possible so that the eyes can gaze directly through the Optics Assembly. (Set optics per instructions provided with your LumiView.)
Optical Section
With the lamp illuminated, check the adjustment by confirming that the light beam is centered in the visual field. If the light is high or low, refer to the detailed adjustment instructions provided with your LumiView@.

Loosen screw that attaches optical section spectacles. Reposition optical section to insure proper alignment with user’s eyes. Tighten screw to maintain optical section location.
Adjusting for User Refractive Error (Spectacle Models Only) The optimal working distance from the object is 15” (38.1 cm) 17” (43.2 cm). If this model is used without corrective lenses and user is myopic or hyperopic, then the user will need to work closer or farther from object, depending on refractive error. To compensate for this, the spectacle models can be fitted with corrective lenses by an eyecare practitioner of your choice. Please bring the following information to assist your eyecare practitioner in fitting your prescription lenses. Lens Template - Spectacle Model Front Sizes

To set IPD properly, observe an object at approximately 15 inches (38 cm). Close the left eye and adjust the IPD control under the right eye until the viewed image is centered. Now close the right eye, keeping the left eye open, and adjust the IPD control for the left eye until that image is centered. Open both eyes and the object should be clear and centered.

Troubleshooting Guide Problem
Solution
Illumination spot is too high and is out of field of view.
Make sure you are 14” to 16” from patient or object under inspection. If you are too close, the illumination spot will be too high. Make sure optical section is aligned with user’s eyes. Suggest looking into the instrument when on user. The user’s eyes should be centered vertically on the center mirrors. & A. optical section too high on user -/B. optical section too low on user
( d;i% ,T, d C. optical section centered cor‘-I rectly on user To correct A and B, simply loosen screw on back of optical section and adjust optical section up or down until image is centered. User encounters glare off of the pneumatic insufflation system.
Clean the glass section with alcohol swab or clean cotton cloth. Rotate pneumatic assembly until glare dissipates.
18
Problem
Solution
Instrument does not illuminate.
Replace 08500 lamp. See page 11 for instructions. Battery is expired or discharged. See page 15 and 16.
Image is distorted or double image is seen.
Instrument must be set correctly for interpupillary distance adjustment. See page 9 for instructions. Depth perception is slightly altered with 3D optical design. Continued usage will improve comfort level.
How do I utilize bifocals?
Install bifocal lenses so that only the upper third is for distance and lower two-thirds is for reading. Adjust the nose bridge so that frame sits higher on nose. Then lower the height adjustment. This will ensure that the binocular viewing system will be positioned in fron of the reading part of the lenses,
