Technical Maintenance and Storage
Technical maintenance should be carried out at least twice a year and include the following steps:
- Wipe the external surfaces of metal and plastic parts free of dust and dirt with a cotton cloth. To avoid damage to the paint coating, do not use chemically active substances, solvents, etc.
- Clean the electric terminals of the Battery Pack and battery slot on the device using a non-greasy organic solvent.
- Check the glass surfaces of the eyepiece and the lens. If necessary, remove dust and sand from the lenses (preferably using a non-contact method). Cleaning of the external surfaces of the optics should be done with substances designed especially for this purpose.
- Always store the device in its carrying case, in a dry, well-ventilated space. It is essential during prolonged storage to remove the Battery Pack.
