Do not drill or screw additional screws into the casing in order to fasten the device; this would damage the device.

When setting up the device, make sure that it has a stable footing and place it on a stable underground, since falling off of the DAB radio may injure persons.

When setting up the device, make sure that the connection cables are neither pinched nor damaged by sharp edges.

Always place cables so that no one can trip over them or be caught in them. Danger of injury!

Due to the diversity of furniture paints and polishes used, it is possible that the device's feet will leave visible residue on furniture. The device therefore should not be placed on valuable furniture surfaces without any suitable protection.

• Place the device on a level and dry surface.
• Unroll the aerial (6) completely.

The radio reception strongly depends on the aerial alignment. If reception is impaired in operation, try aligning the aerial differently.

The plug-in mains adapter is only approved for connection to 100-240 V/50/60Hz alternating voltage. Never try to operate the device with any other voltage.

Make sure when connecting that the connection cable is not squeezed or damaged by sharp edges.

The mains outlet to which the mains adapter is connected must be easily accessible so that the mains adapter can be separated from the mains voltage quickly in case of an error.

• Connect the low-voltage plug of the mains adapter to the DC 5V connection (5).
• Plug the mains adapter into a wall socket.

  Allow the device to reach room temperature before connecting it. Wait until the condensation has evaporated. This may take several hours.
• Never plug in or unplug mains adapters when your hands are wet.
• Never pull mains adapters from the mains socket by pulling the cable. Always pull the mains plug from the mains socket by the intended grip areas.
• Unplug the mains adapter from the mains socket if you do not use the device for some time.
• To warrant sufficient ventilation, an area of 5cm must be kept free around the device and mains adapter. Air circulation also must not be impaired by any objects like magazines, tablecloths, curtains, etc.
• For safety reasons, disconnect the mains adapter from the mains socket in case of an electrical storm.
• Do not listen to excessively loud music over an extended period of time. This may damage your hearing.

Maintenance and Care

Always observe the following safety information before cleaning or servicing the device:

Unplug the mains adapter from the mains socket.

Only qualified experts familiar with the hazards involved and the relevant regulations must perform repairs or open the device.

The device is maintenance-free and you should therefore never open it.

Clean the exterior of the device with a soft, dry cloth or brush only. Never use any aggressive cleansing agents or chemical solutions since these may damage the casing or impair its function.

Regularly check the technical safety of the device, e.g. for damaged casing, mains adapter, etc.

If you have reason to believe that the device can no longer be operated safely, disconnect it immediately and make sure it is not unintentionally operated.

It can be assumed that safe operation is no longer possible if:

• there is visible damage to the device or to the mains adapter,
• if the device or mains adapter no longer works,
• the device was stored under unfavourable conditions for an extended period of time or
• after exposure to extraordinary stress caused by transport
