Precautions
• Do not clean non-optical surfaces of the thermal imager with
a chemical solvent, but wipe with a soft cloth.
• The lens has a special coating to enhance the optical
performance. Cleaning is only necessary if the lens is clearly
dirty. Rubbing too hard can cause the lens coating to wear
out. Do not touch the surface of the lens, as acidic materials
of the skin can damage the coating. Use compressed air or a
soft brush or possibly a soft spectacle cloth.
• When the thermal imager will not be used for a longer
period, please check it every six months.

Warning
• Do not expose the thermal imager directly to high intensity
radiation sources such as the sun, carbon dioxide lasers and
electric welding machines.
• Keep the time interval between power on and power off at
least 20 seconds.
• The Lahoux Spotter contains advanced optical and
electronic components. Prevent unnecessary shock, drops
and vibrations to prevent damage.
• Do not disassemble the thermal imager yourself. In case
of malfunction, contact the supplier in time. Unauthorized
disassembly of the Lahoux Optics will irrevocably void the
warranty.
