NOTES on Cleaning
Clean the eyepieces and/or lenses only with
a soft, lint-free cloth, (e.g. microfi bre cloth). To
avoid scratching the lenses, use only gentle pres-
sure with the cleaning cloth.
To remove more stubborn dirt, moisten the clean-
ing 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 for a short period of time, so that the
residual moisture can dissipate before storing.
Put on the dust cover and store it in the included
bag.
Before cleaning the device, disconnect it from the
power supply (remove batteries)!
