Read and understand the Device Operating Manual before using this device DO NOT use if packaging is damaged. Avoid prolonged contact with the camera during use at it may be warm. Standard Working Distance is 16 inches (40 cm) minimum. Use caution when operating at closer distances. Use Pharos HDTM only with BFWTM/Long Island Technology GroupTM products or accessories. DO NOT subject the Pharos HDTM to strong shocks, which includes but is not limited to dropping the device on the floor. DO NOT use this device for other than its intended use. DO NOT modify this equipment. DO NOT open this device. No serviceable components are inside this device. Only Qualified Personnel should operate the Pharos HDTM DO NOT submerge this device or any of its components in liquid. Stacking or placing close to other equipment may negatively impact EMC compliance. Use only video output devices that have been tested to pass Low voltage regulations (IEC 60950 or IEC 60601-1). Failure to do so may decrease system performance and could result in non-compliance. USE ONLY components and accessories listed on page 5 of this manual. Failure to do so may decrease system performance, may lead to unsafe operation, may negatively affect EMC performance and could result in non-compliance and could void the warranty.

Warnings and Cautions Intended Use
The Pharos HDTM Surgical High Definition Camera is a device intended to generate a High Definition video image of the area illuminated by a surgical light. The image is intended to be used for remote observation of the surgeon's view of the surgical field. The unit provides output connectors that allow the image to be displayed on remote monitors or connected to a video transmission system for presentation in distant locations. The intended environment of use is for Professional Health Care.

Overview System Description
The Pharos HDTM Surgical High Definition Camera system is mounted on a headband. The unit is constructed of a durable plastic housing encasing a precision aluminum Lens Holding System with Glass Anti-Reflective Coated Lenses and a CMOS high definition 1080p 60 Hz video camera. The camera lens is designed in a “periscope” configuration so the lens is located exactly in the center of the optics. This ensures that the image generated by the camera will be aligned with the surgeon's line of sight and the video image presents exactly what the surgeon sees. The device is articulated on the headband, allowing the camera to be turned left and right for ease of aiming.
The device is attached to a headband, which allows the medical professional to wear the camera on their head. The headband mounting system adjusts for comfortable fit and allows the camera to be adjusted for position between the user's eyes. The device also allows for adjustment to the cameras focus simply by rotating the Focus Adjustment lens. For information on how to use the Phaors HDTM with approved accessories see the Pharos HDTM Accessories Manual.

Assembly and Operation Changing Lenses
1. Rotate the Lens Tube counter-clockwise until the lens is fully disengaged from the periscope. 2. Take the second Lens Tube and screw it into the periscope.
! !
Do not allow dust or dirt to get inside the periscope as it will degrade the quality of the image Make sure the lens is sufficiently threaded before use
Lens Identification
The Pharos HDTM has two options of Lens Tubes that provide different field of views.
Standard Lens (20mm focal length) Identified by the black ring around the front
Wide Lens (15mm focal length) Identified by the light blue ring around the front
