make sure that the mains plug is
always easily accessible.

– If the device emits smoke, smells

burnt or produces unusual sounds,
immediately disconnect it from the
mains and do not operate it further.

– Never open the device housing.

Repairs of the device may only
be carried out by an authorised
specialist workshop. Only parts
that match the original specifica­tions may be used.

– Only use the accessory products

specified by the manufacturer.

– Never modify the device. Unauthor-

ised modifications may affect the
safety and functionality.

WARNING

An unsuitable setup location may
result in injury and damage.

– If the speaker is not securely

mounted, do not use it in vehi­cles, in unstable locations, on
wobbly tripods or furniture, on
underdimensioned brackets etc.
The speaker may tip or fall over
and cause injury to persons or be
damaged itself.

– Position the speaker in such a way

that it cannot be knocked over
inadvertently and make sure that
the cables do not pose a tripping
hazard.

– Do not use the device in envi-

ronments where there is a risk of

the device or the plastic wrapping.
There is a danger of suffocation.

– Never allow children to operate

electrical equipment unsupervised.

WARNING

Lithium rechargeable batteries
can explode if handled improperly.

– You must not heat or short circuit

rechargeable batteries or dispose
of them in fire.

– Do not expose the rechargeable

batteries to direct sunlight.

– Do not place the speakers near

heat sources (e.g. heaters, ovens,
other heat generating equipment
such as amplifiers etc.).

6 • ROCKSTER GO

CAUTION

Extended listening at
high volumes may lead
to hearing loss.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
your signal source device volume
control to a low setting before
turning on the power.

CAUTION

Batteries (particularly lithium
batteries) can explode if used
improperly.

– You must not heat or short circuit

rechargeable batteries or dispose
of them in fire.

– Do not expose the rechargeable

batteries to direct sunlight.

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 GO is splash-proof
but not watertight!

– The splash-proof protection is only

effective if the rubber cap on the
USB port seals it off properly.

– Normal rain and a few splashes

from showering won’t cause any
damage, but you should avoid
spraying it directly with a hose.

– If the ROCKSTER GO falls into

a paddling pool, fish pond or
other flat water body, nothing will
happen if you recover it right away.
However, the device is not suitable
for diving!

– You should generally avoid contact

with salt water.

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.

– 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.

7 • ROCKSTER GO

– 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 GO 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.

Used rechargeable
batteries must not be
disposed of with house­hold waste!

Every consumer is required by law to
bring all batteries and rechargeable
batteries, regardless whether they
contain harmful substances or not, 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!

Troubleshooting

The following advice should help you to solve problems. If this does not work, our
online manual will provide help:

https://manual.teufelaudio.com

Problem Possible cause/solution

The
ROCKSTER GO
doesn’t emit
sound.

The rechargeable battery is empty.Charge the rechargeable
battery.

No sound. The volume has been set too low. Increase the volume.

The volume of the external player has been set too low.
Carefully increase the volume of the external player.

No sound with
Bluetooth®.

No Bluetooth® connection.Establish a connection (see
„Bluetooth®“ on page 15).

ROCKSTER GO has not been selected as the output device.
On the external player, select “Teufel ROCKSTER GO” as the
Bluetooth® output device.

Bluetooth® connection impaired by another radio system
(e.g. cordless telephone, Wi-Fi). Move the devices causing
the disturbance.

Playback is noisy. Generally speaking, the ROCKSTER GO is a very low-noise

system. In most cases, the speaker system with very high
resolution in the high range area can expose the poor
quality of a signal source (e.g. from MP3 files).Ensure that
the source is sending a clear signal to the ROCKSTER GO.

The voice assis­tant doesn’t
work.

Activate the voice assistant on the smartphone.
