Care and cleaning
The devices performance
and serviceability are condi-
tional on regular care and
immediate attention to
problems:
• Do not touch glass lenses
with fingers.
• Do not soil the operating
keys with oil or grease.
• Avoid abrupt
temperature transition,
since these can cause
condensation
moisture to develop inside
the device.
The device does not need
special care or cleansers.
Therefore
• do not use any kind of
impregnated cloth
intended for cleaning
spectacle lenses,
• do not use any solvent
except water, e.g. no
alcohol or cleansers.
Lens cleaning
Particles of dirt should be
blown off or removed using
a soft brush.
Finger prints may be
cleaned first by wiping with
a damp cloth, followed by
soft, clean optical tissue or
chamois leather.
