The Rechargeable Battery
You can operate the
ROCKSTER CROSS via the enclosed
mains adapter or the integrated
rechargeable battery.
– Before first use, charge the
rechargeable battery for approx.
3 to 4 hours.
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 recharge-
able batteries to direct
sunlight.
–Use only the enclosed mains
adapter for charging.
The integrated lithium ion recharge-
able battery provides up to 20 hours
of operating time – regardless of the
volume and the amount of bass in
the tracks played.
Thanks to the Powerbank function,
you can charge another device (e.g.
smartphone) via the CHARGING USB
jack (15).
Please observe the maximum
charging current of 0.5A and that
charging an external device reduces
the operating time.

You can display the rechargeable
battery charge level by tapping the

<10% Bottom LED is flashing
To protect the rechargeable battery, the
ROCKSTER CROSS has deep discharge
protection, which switches the device
off once the threshold is reached.
If the rechargeable battery
charge diminishes, the
ROCKSTER CROSS will emit two
short warning tones several times
and the LED at the bottom of the
rechargeable battery indicator (8)
will blink. Depending on the volume,
operation will still be possible for up
to 60 minutes.
In this case, connect the mains
adapter as soon as possible.

adapter to the POWER jack (17)
and connect the mains adapter to a
socket (100–240V~, 50/60 Hz) via
the mains cord(3).

around the button (5) will now light
up continuously in white and a tone
will sound siganling connection.
Both devices will now play the
same music.

Bluetooth®
Via Bluetooth®, you can estab-
lish a wireless connection
between a compatible external
player (e.g. smartphone) and the
ROCKSTER CROSS. The audio output
of your external player is then emitted
by the ROCKSTER CROSS.

devices and have them played in
alternation.
For smartphones with Android or
an IOS operating system, you can
also use the voice assistant via the
ROCKSTER CROSS.
Bluetooth®options
Depending on the device type and
operating system, your external
player/smartphone may also have a
number of Bluetooth®options such
as media playback and call function.
Here you can activate and deactivate
the desired options.
You can find more information about
the Bluetooth®options in the user
manual for your external player/
smartphone.
Pairing
To play the audio of your external
player on your ROCKSTER CROSS
via Bluetooth®, you must first
connect the devices with each
other. This is called “Pairing”.

player. After the search run, the
“Teufel ROCKSTER CROSS” should
also be present in the list of
detected devices.

“Teufel ROCKSTER CROSS”
from the list of detected devices.
Pairing is now complete and your
ROCKSTER CROSS will now act as

Care And Cleaning
• Only use plain water or a mild soap
solution.
• Do not use any abrasive cleaners,
brushes with metal or nylon
bristles, or sharp or metallic
cleaning utensils such as knives,
hard scrapers and the like. They
could damage the surfaces.

dirt with a dry, smooth cloth.
2. Use a damp cloth to rub off
stubborn dirt. Make sure that no
liquid penetrates the housing.
3. Immediately wipe the damp
surfaces off with a soft cloth
without applying pressure.
• If the device is to be left unat-
tended for a prolonged period of
time (e.g. during a vacation) or if
a thunderstorm is forecast, pull
the mains plug out of the socket.
Otherwise, sudden overvoltage
could cause the device to become
defective.
