Guidelines for the safe use of the Solid State
Portable Headlight

General practices to minimize risk of harm to the skin
from optical radiation hazards include: minimizing
illumination intensity at the tissue examination site,
minimizing exposure times, and taking additional
precautions when skin sensitivity has been altered
through tissue trauma or the use of anesthesia.
General good practices to minimize risk of harm to the
eyes from optical radiation hazards include: Avoiding
looking at bright light sources and their reflections, and
protect eyes where normal pupil sizes and aversion
responses are not present.

Set-up and Operation

Instructions for Use

The Solid State Procedure Headlight (REF 49020), consisting of Procedure
Headlight (REF 49000) with Direct Power Source (REF 75270), and
Accessory Portable Power Source/Charger (REF 75260). The Solid State
Procedure Headlight is designed to operate off the direct or the portable
power source. To operate the headlight using the direct power source,
follow the instructions and illustrations in the section labeled Direct Plug-In
Transformer. Simply turn on the on/off switch located on the Direct Plug to
operate the headlight. To operate the headlight using the portable power
source, follow the instructions and illustrations under the section labeled

Guideance

The REF 49000 uses RF energy only for
its internal function. Therefore, its RF
emissions are very low and are not likely
to cause any interference in nearby
electronic equipment.

The REF 49000 is suitable for use in all
establishments, including domestic, and
those directly connected to the public
low-voltage power supply network that
supplies buidlings used for domestic
purposes.
