Cleaning & Maintenance
Giant binoculars
• Clean the lenses (eyepieces and/or objective lenses) only with a soft and lint-free cloth
(e.g. microfibre cloth). To avoid scratching the lenses, use only gentle pressure with the
cleaning cloth.
• To remove more stubborn dirt, moisten the cleaning cloth with an eyeglass-cleaning
solution and wipe the lenses gently.
• Protect the device from dust and moisture! After use, particularly in high humidity, let the
device acclimatise at room temperature for a short period of time, so that the residual
moisture can dissipate. Put the dust caps on and store it in a dry and heated place.
U-Mount and tripod
• Clean the device only on the outside
with a dry cloth.
