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.
