Maintenance 
Technical Inspection 
It is recommended to carry out a technical inspection before each use of the 
device. Check the following: 
•  The device appearance (there should be no cracks on the body). 
•  The state of the objective and eyepiece lenses of the thermal imaging module 
(there should be no cracks, grease spots, dirt or other deposits). 
•  The state of the rechargeable battery (it should be charged) and the electric 
contacts (there should be no signs of salts or oxidation). 
•  The controls should be in working order. 
•  The thermal imaging module is properly and firmly fixed on the optical device. 
 
Technical Maintenance and Storage 
Maintenance should be carried out at least twice a year and include the 
following steps: 
•  Wipe the exterior metal and plastic surfaces with a cotton cloth to remove dust 
and dirt. To avoid damage to the paint coating, do not use chemically active 
substances, solvents, etc. 
•  Clean the electrical contacts of the rechargeable battery on the device using a 
non-greasy organic solvent. 
•  Check the eyepiece and the lens and if required remove dust and dirt from the 
optics (preferably using a non-contact method). Cleaning of the exterior 
surfaces of the optics should only be done with products specifically designed 
for this purpose. 
•  Always store the device in its carrying case in a dry, well-ventilated space. For 
prolonged storage, remove the batteries.
