LASER SAFETY
The VS903 utilises a Class II laser that emits low levels of visible radiation (i.e. wavelengths between 400 and 700 nanometres)
which are safe for the skin but not inherently safe for the eyes. The Class II emission limit is set at the maximum level for which eye
protection is normally afforded by natural aversion responses to bright light. Accidental eye exposure is therefore normally safe,
although the natural aversion response can be overridden by deliberately staring into the beam, and can also be influenced by the use
of alcohol or drugs.
p WARNING! Do not look or stare into the laser beam as permanent eye damage could result.
7DO NOT direct the laser beam at any person’s (or animal’s) eyes as eye damage could result.
8DO NOT operate the thermometer when you are tired or under the influence of alcohol, drugs or intoxicating medication.
3Be aware that reflections of the laser beam from mirrors or other shiny surfaces can be as hazardous as direct eye exposure.

INTRODUCTION & SPECIFICATION
Quick and easy way to diagnose engine and vehicle faults. VS903 Detects energy emissions in the infrared spectrum and converts
them into a display of temperature within 1 second of use. Medium resolution 6:1 optics allow accurate readings even in areas of
temperature clutter. Features laser pointer to indicate the area being sampled. Temperature is displayed on a backlit LCD panel with
automatic hold. Temperature can be shown in either °C or °F. Powered by 2 x AAA batteries.
