Warnings and Cautions Users of this product should be thoroughly trained in the appropriate medical procedures. Also they should read and understand this owner’s manual for this headlight and all equipment used with it.
! ! ! ! ! ! ! ! ! !
DO NOT shine light into eyes. Eye injury may result DO NOT use if packaging is damaged. Use Headlight only with Long Island Technology Group accessories, power supplies, batteries, and controllers. DO NOT modify this equipment Service must be performed only by Long Island Technology Group or properly trained biomedical technician Avoid prolonged contact with the headlight during use as it may be hot USE ONLY components and accessories listed on page 5 and 18 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 WARNING Use of this equipment adjacent to or stacked with other equipment should be avoided because it could result in improper operation. If such use is necessary, this equipment and the other equipment should be observed to verify that they are operating normally. WARNING Portable RF communications equipment (including peripherals such as antenna cables and external antennas) should be used no closer than 30 cm (12 inches) to any part of the Bristol PlusTM, including cables specified by the manufacturer. Otherwise, degradation of the performance of this equipment could result. Medical Electrical Equipment needs special precautions regarding EMC and needs to be installed and put in service according to the EMC information in the Electromagnetic Capability of this manual.

Warnings and Cautions Intended Use
The Bristol Plus™ is an ultra-portable medical light source. The device is intended to be mounted on a headband or to the glasses frame of the doctor’s loupes or eye wear. An Iris system permits the light spot size to be adjusted. The light is an excellent supplementary light source for examinations and procedures. The advantage of the Bristol Plus™ system is that the light is positioned between the doctor’s eyes, making the direction of illumination always in the exact direction of the doctor’s vision. The intended environment for use is for Professional Health Care except for near active HF Surgical Equipment and the RF shielded room of an ME System for magnetic resonance imaging. Please follow the maintenance instructions on page 17 in order to maintain basic safety.
