Notes on cleaning
Clean the eyepieces and/or lenses only with a soft, lint-
free cloth, (e.g. a microfi bre 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 acclimatize
10
for a short period of time, so that the residual moisture
can dissipate before storing.
DISPOSAL
Dispose of the packaging materials properly, according
to their type, such as paper or cardboard. Contact your
local waste-disposal service or environmental authority
for information on the proper disposal.
