Preventing damage to health and accidents
▷
Protect your hearing from high volume levels. Permanent hearing
damage may occur when headphones are used at high volume
levels for long periods of time. Sennheiser headphones sound
exceptionally good at low and medium volume levels.
▷
Keep the product, accessories and packaging parts out of reach
of children and pets to prevent accidents and choking hazards.
▷
Do not use the product in an environment that requires your spe-
cial attention (e.g. when performing skilled jobs).
Preventing damage to the product and malfunctions
▷
Allow the product to stand for at least 2 hours before putting it
into operation. Condensation can form inside the product if it is
moved from a cold environment to a warm environment.
Notes on the use and disposal of storage media
You can use the supplied USB flash drive for storing personal data. If
the flash drive is sold/passed on or disposed of, the data once stored
on it and then deleted using a standard delete method can be recov-
ered with special software and be misused.
We therefore recommend using special software for secure deletion
of data to ensure that personal data is not misused.
We recommend backing up the data saved on your flash drive regu-
larly. Sennheiser does not accept liability for damage or loss of data.
