INTRODUCTION & SPECIFICATION
Fast and simple way to tackle diagnosis of engine and vehicle faults. VS904 detects energy emission in the infrared spectrum and
converts reading into a display of temperature. Features laser pointer to indicate area being sampled. Temperature is displayed on a
large LCD panel. Temperature can be shown in either °C or °F. Powered by 2 x AAA batteries (not included).

1.2
LASER SAFETY.
The VS904 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.
!
WARNING!
Do not look or stare into the laser beam as permanent eye damage could result.
$
DO NOT
direct the laser beam at any person’s (or animal’s) eyes as eye damage could result.
#
DO NOT
operate the thermometer when you are tired or under the influence of alcohol, drugs or intoxicating medication.
"
Be aware that reflections of the laser beam from mirrors or other shiny surfaces can be as hazardous as direct eye exposure.
