Maintenance should be carried out no less frequently than twice a year, and should consist of the following measures:
- Wipe external plastic and metal 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 electric contacts of the Battery Pack using a non-greasy organic solvent.
- Inspect the objective lenses, eyepieces and IR illumanator and if required, remove dust and dirt (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.
- Store the device in a carrying case. Remove the Battery Pack for long-term storage.
