! Warnings, cautions and notes
Definition
Warning Represents a dangerous situation or act that may result in
personal injury or death.
Caution Represents a situation or action that could result in damage to the
camera or permanent loss of data.
NOTE Indicates a useful hint for the user.
Important information –Please read before using the instrument
Caution –As the camera uses a very sensitive thermal sensor, the lens must
not be pointed directly at a strong source of radiation (e.g. sun, direct laser
beam or reflection) under any circumstances (on or off) as this will cause
permanent damage to the camera！
Caution - The camera must be transported in its original box and must not be
shaken or bumped strongly during use or transport.
Caution –It is recommended that the camera be stored in its original case in a
cool, dry, ventilated environment free from strong electromagnetic fields.
Caution - Avoid staining the surface of the lens with oil and various chemicals
and damaging the surface. Close the lens cap after use.
Caution - To prevent the potential risk of data loss, always copy (back up) data
to your computer.

3
NOTE - The camera may require a 3-5 minute warm-up process before
accurate readings can be taken.
NOTE - Every thermal imaging camera is factory calibrated for temperature
and it is recommended that this be done annually.
Caution - Do not open the case or make modifications without permission,
repairs should only be carried out by authorized personnel.
