1. PRECAUTIONS AND SAFETY MEASURES
The instrument has been designed in compliance with the directives relevant to electronic
measuring instruments. For your safety and in order to prevent damaging the instrument,
please carefully follow the procedures described in this manual and read all notes
preceded by the symbol with the utmost attention. The following symbol is used in this
manual:
When this symbol is displayed, the instrument is able to emit a laser pointer.
Always prevent the laser from radiating your eyes, in order to avoid any
injury. Class 2 laser device according to EN 60825-1.
1.1. PRELIMINARY INSTRUCTIONS
CAUTION
CAUTION
Use the instrument only as specified in this user manual. Improper use may
damage the instrument.
During use and storage, keep the instrument away from direct sunlight or
sources of light, hot surfaces or objects, high temperatures, high humidity
or particularly critical environmental conditions.
After a period of storage under extreme environmental conditions, let the
instrument resume normal operating conditions before using it.
Moving the thermometer quickly from a cold to a warm place it may
condense on the focal lens from which infrared radiation is captured. Wait
until condensation is absorbed before taking measurements.
Do not touch the internal focal lens.
Make sure that the target is larger than the unit's spot size. The smaller the
target, the closer you should be to it. When accuracy is critical, make sure
the target is at least twice as large as the spot size.
Do not carry out measurements under conditions exceeding the limits
specified in § 7.
Make sure that battery is correctly installed.
Do not carry out any measurement if you notice anomalous conditions such
as breakages, leakages of battery liquid, blind display, etc.
This instrument is not recommended for use in measuring shiny or polished
surfaces (stainless steel, aluminum, etc.).
The instrument cannot measure IR temperature through transparent
surfaces such as glass. The instrument will measure the surface
temperature of the glass instead.
Steam, dust, smoke, etc. can prevent accurate IR measurements.

1.2. DURING USE
Please carefully read the following recommendations and instructions:
CAUTION
Never press the trigger T when symbol is displayed and the instrument
is directed towards the eyes. The instrument emits a laser pointer.
If the target has a smooth surface reflec ting the laser, prevent the laser from
beaming your eyes.
If symbol “ ” is displayed during use, interrupt testing and replace the
batteries according to the procedure described in § 6.2
Be extremely careful when the laser pointer is turned on.
Do not direct the instrument, especially the laser beam, towards people or
animals.
When using the laser pointer, be careful no to direct the beam onto a
reflective surface which could reflect the beam into your eyes.
Never radiate the laser if flammable gas is present.
1.3. AFTER USE
If the instrument is not to be used for a long time, remove the batteries
