It is recommended to inspect your riflescope before each use. Check the following:

• The device should be free of any cracks or deformations.
• The lenses of the eyepiece and objectives should be free of cracks, grease, dirt or debris.
• The state of rechargeable batteries (should be fully charged). Electrical sockets should be free of salts, oxidation, or other debris.
• All controls should be responsive.

Maintenance should be carried out at least twice a year and should include the following steps:

• Wipe the exterior surfaces of metal and plastic parts with a cotton cloth. Do not use chemically active substances, solvents, etc. as these will damage the paint.
• Clean the electric contacts of the battery pack and battery slots on the riflescope using a non-greasy organic solvent.
• Recharge the battery if necessary (50%-80% is recommended for normal use).
• Check the lenses of the eyepiece and objectives. If necessary, remove dust and sand from the optics (it is preferable to use a non-contact method). Cleaning of the exterior surfaces of the optics should be done with cleaners designed especially for this purpose.
