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

Finger prints may be
cleaned first by wiping with
a damp cloth, followed by
soft, clean optical tissue or
chamois leather.
