Care and cleaning
The devices performance and
serviceability are conditional 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.
Cleaning the casing
Wipe the casing with a damp
cloth. Pay special attention to
dirt and grease around the
keys.
Blow out the device interface
cable socket, and clean it
carefully.
Allow the device to dry fully
before packing.
