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.
Clean the electrical contacts of the rechargeable battery on the device using a non-greasy
organic solvent.
Check lenses of objective, eyepiece and rangefinder. If necessary, remove the particles
of dust and sand (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.
