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:
CAUTION
When this symbol is displayed, the instrument is able to emit a laser pointer.
Always prevent the laser from radiating to your eyes, in order to prevent
any injury. Class 3R laser device according to EN 60825-1.
1.1. PRELIMINARY INSTRUCTIONS
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 in extreme environmental conditions, let the
instrument resume normal operating conditions before using it.
If the thermometer is moved quickly from a cold to a hot environment, some
condensation may appear on the focal lens which catches infrared
radiation. Wait for the condensation to dissipate 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 batteries are 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 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 measurement.

1.2. DURING USE
Please carefully read the following recommendations and instructions:
CAUTION
Never press the trigger 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 reflecting the laser, prevent the laser from
radiating to the eyes.
Never radiate the laser if flammable gas is present.
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 the 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.
