Important safety instructions
Do not subject the operating elements, connections and cables to violence.
The device may only be operated at the voltage and frequency specified on the plug-in power supply or the rating plate.
Do not place any objects in the device's openings as they may come into contact with and/or damage live wires or components inside the casing.
This may in turn lead to a short circuit, electric shock, or fire.
Use only mounting materials and accessories that have been approved by the manufacturer and/or provided together with the device.
Clean this device with a clean, dry cloth only.
Do not use aggressive, alcohol-based or abrasive cleaning agents.
To prevent electric shocks, refrain from opening the device. The device does not contain any parts to be maintained by the user.
Service and repair work is only to be performed by qualified professionals. This is necessary if the device has been damaged in any way, for example
if fluids or other objects have come into contact with the power cord or plugs, if the device has been exposed to water or moisture, if it does not work
properly, or if it has fallen.
Do not make any adjustments to the device or accessories. Any unauthorised adjustments can compromise the device's safety, its compliance with legal
provisions, or its system performance. In such an event, the device's operating license and guarantee become extinct.
If the device's audio is distorted, emitting, for example, unnatural knocking, tapping or high-frequency clicking, reduce the volume immediately.
To prevent the risk of hearing loss, do not listen at high volumes for long periods. Pause the device if you hear ringing or whistling
in your ears or if you feel you cannot perceive high-pitched sounds properly [ even if this is just short-term ]
Do not expose the batteries to high temperatures, for example direct sunlight, fire or similar.

The device may only be operated in ambient temperatures of between 0 and 45 °C.
The integrated battery may only be charged in ambient temperatures of between 0 and 35 °C. We recommend a temperature of 15–25 °C.
Temperatures outside this range can lead the device to stop playing or stop charging [ protective circuit ].
Do not under any circumstances store the device at temperatures below –10 °C or above 45 °C.
Avoid subjecting the device to extreme knocks and vibrations.
Use only the plug-in power supply provided to operate and charge the device.
The device and | or accessories kit can contain parts small enough to be swallowed.
They are therefore not suitable for children under 3 years of age.
This symbol indicates that, under the casing, there are uninsulated, dangerously high-voltage parts with an amplitude strong enough
to cause fire or electric shock.
This symbol indicates important operation and service instructions in the documents [ safety instructions, quick start guide ] included.
This symbol indicates that the device is a protection class II appliance, i. e., an appliance that protects against electric shock by having
double or strengthened insulation. It therefore does not require a protective earth connection.
