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.
Rechargeable battery

You can display the rechargeable
battery charge level by tapping the
button (9).

<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.

The integrated Li-Ion rechargeable
battery starts charging as soon as the
ROCKSTER CROSS is supplied with
power from the mains adapter (2).
Connect the small plug of the mains
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).
