cluding cables specied by the manufacturer. Otherwise, degradaon of the performance of this equip-
ment could result.
!Medical Electrical Equipment needs special precauons regarding EMC and needs to be installed and

Intended Use
The BFWTM DaymarkTM LED Headlight is a device intended to supply supplemental, constant and con-
trolled illumination during medical procedures. This device is designed for use in the operating room. The
advantage of the DaymarkTM system is that the light is positioned between the medical professional’s eyes and
the direction of illumination is always in the exact direction of the medical professional’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 assembly instructions on
page 6 and maintenance instructions on page 17 in order to maintain basic safety.

Overview
System Descripon
The BFWTM DaymarkTM LED Headlight is constructed of durable plastic housing encasing a precision
aluminum lens system holder with glass anti-reflective coated lenses and a spot size adjusting iris. Light is
provided by a high power LED, driven by a solid state controller and battery to provide ON/OFF and 5 levels of
light output. The system includes two spare batteries and a battery charging system. The device is articulated,
allowing the lower part of the light to be turned left and right for ease of aiming.
As shown below the device is attached to a headband, which allows the medical professional to wear the
headlight on their head. The headband mounting system adjusts for comfortable fit and allows the light to be
adjusted for position between the user’s eyes so illumination is shadow free.
Two styles of headbands are available, the Classic headband as shown below, constructed of plastic with knobs
for size adjustment, and the Key West headband, designed to be lighter and more comfortable. (not shown)
