It is recommended to carry out a technical inspection each time before using the riflescope. Check the following:
The riflescope appearance (there should be no cracks on the body).
The condition of the lens and eyepiece (there should be no cracks, greasy spots, dirt or other deposits).
The state of the battery pack (must be charged to a level of 50-70%) and the electric contacts within it (there should be no signs of salts or oxidation).
