and suffocate.
– Do not allow children to play with
the device or the plastic wrapping.
There is a danger of suffocation.
– Never allow children to operate
electrical equipment unsupervised.
CAUTION
Extended listening at
high volumes may lead to
hearing loss.
To avoid damage to health, avoid
extended listening at high volumes.
– To avoid damage to health, avoid
extended listening at high volumes.
– When the volume is set high,
always keep a certain distance
from the device and never place
your ears directly on the speaker.
– If a speaker is set to full volume,
this may produce very high sound
pressure. This may have psychological consequences and also
cause physical injury. Children and
pets are particularly at risk. Set
the volume control of your external
player to low volume before you
turn it on.
CAUTION
This product contains magnetic
material.
– If necessary, consult your physician
and ask for effects on implants
such as pacemakers or defibrillators.
NOTICE
The ROCKSTER CROSS is splashproof but not watertight!
– The splash-proof protection is only
effective if the rubber caps on the
connections seal them off properly.
– Normal rain and a few water
splashes won’t cause any damage,
but you should avoid spraying it
directly with a hose.
NOTICE
Gross misuse and incorrect care
are the main reasons for damage
to high-performance rechargeable
batteries.
– Avoid deep discharge of under
20% for optimal rechargeable
battery power.
– Recharge your rechargeable
battery frequently.
Page 7
7 • ROCKSTER CROSS
– Store your rechargeable battery in
a cool, but frost-free area, ideally
at 15 °C. Higher temperatures
result in a higher rate of self-discharge and shorten the intervals
between charges.
– Do not expose the rechargeable
battery to direct sunlight or other
sources of heat.
– A deep discharge damages the
rechargeable battery cells. The
most frequent cause of deep
discharge is prolonged storage or
failure to use a partially discharged
rechargeable battery. Only store
the rechargeable battery once it is
fully charged.
Old devices must not be
disposed of with household waste!
If the ROCKSTER CROSS
is no longer operational, every
consumer is required by law to
dispose of used devices separately
from household waste, e.g. at a
collection point run by the communal
authority/borough. This ensures
that old devices are recycled in a
professional manner and also rules
out negative consequences for the
environment.
For this reason, electrical equipment
is marked with the adjacent symbol.
Rechargeable
batteries must not be
disposed of with
household waste!
Every consumer is required by law to
bring all batteries and rechargeable
batteries to a collection point run by
the communal authority/borough
or to a retailer, so that they can be
disposed of in an environmentally
friendly manner.
Please only turn in batteries and
rechargeable batteries which are
empty!
