These parts, like the remote control battery, could be swallowed and cause suffocation. In case of swallowing any parts, contact a doctor immediately.
• Danger of injury or damage! When moving the speaker, take care to avoid injury and damage!
• Caution! Since the speaker can only be completely disconnected from the mains at the mains input on the rear of the unit or by pulling the mains plug from the socket, it must be positioned so that you have free access to the mains input or mains plug.

If any of the following situations occurs, the loudspeaker must be switched off immediately and disconnected from the mains:

• The speaker has been damaged or has fallen down.
• Power cord or plug is damaged.
• Objects or liquid have got into the loudspeaker.
• The speaker has been exposed to excessive moisture or rain.
• The speaker does not work properly or exhibits a significant reduction in performance.
• The loudspeaker smells burnt, develops smoke or makes unusual noises.

Caution!

The driver in this loudspeaker produces a strong magnetic field in its immediate vicinity that can affect or damage other equipment close by. It is therefore imperative that you keep magnetically sensitive devices and items away from the loudspeaker. Never place CRT screens, notebooks, hard drives or similar on the loudspeakers!

Only use accessories recommended by Nubert!

Installation Instructions

Caution!

An unstable location can damage the speaker.

• Only place the loudspeaker on a flat, stable surface and make sure that it cannot be knocked over!
• Also make sure that no unintentional pulling can occur on the cables to avoid knocking over the speaker or damaging the connection sockets!
• Keep strong mechanical shocks away from the loudspeaker!

Caution! Excessive heat build-up inside the unit can shorten its service life or lead to fire.

• Never cover the back of the speaker! Make sure that there is a clearance of at least 10 cm and sufficient air circulation in the back area!
• Do not operate the speaker and remote control near heat sources such as radiators or stoves!
• Do not set the speaker and remote control to direct sunlight.
• Do not expose to direct sunlight!
• Never place burning candles or similar open fire sources on the loudspeaker!

• In environments where there is a risk of fire or explosion!
• At extremely low or extremely high temperatures!
• Near flammable gases or vapours!
• Near strong dust!
• Near flammable materials!

Danger of Electric Shock!

The loudspeaker carries mains voltage and voltages higher than 35 V AC or DC inside. It has no special protection against the intrusion of liquids or objects into the system. There is therefore a risk of lethal electric shock.

• Never touch the speaker with wet hands!
• Only use the speaker in a dry place!
• Do not operate it outdoors or in damp rooms!
• The loudspeaker must be protected from liquids of all kinds, including dripping and splashing water.
• Do not place any containers containing liquids (e.g., flower vases) on the speaker or in the immediate vicinity!
• If the loudspeaker is moved from a cold environment to a warm room, condensation may form inside the unit. Wait at least six hours until the loudspeaker has reached room temperature and is dry before switching it on!
• No objects or foreign bodies may get into the device.
• Should the loudspeaker come into contact with liquids or should objects have got inside, please unplug the mains plug immediately and contact Nubert electronic GmbH (info@nubert.de)!

Danger of Injury or Damage!

For speakers with threaded bushings on the underside:

• The threaded bushings may be used for upright mounting of the loudspeaker on suitable base plates only.
• The threaded bushings on the underside of the loudspeaker enclosures are not designed for tensile loads and must therefore not be used as holders for hooks or similar devices in order to suspend the loudspeaker cabinet.
• A falling speaker may cause serious injury and damage.

Connection Instructions

General Connection Instructions

• Disconnect the mains plug before changing any wiring on the system!
• Make sure that all connections have been made correctly and that all plugs are firmly seated in the sockets before connecting the speaker to the mains.
• Use only the intended cables or plug connections for the connections! Failure to do so may result in damage or malfunction.
• If you want to disconnect connections on the loudspeaker, always pull the plug, never the cable!
• Ensure that all plugs are firmly seated in the sockets!
• Only use cables and accessories recommended by Nubert!

Danger of Electric Shock!

Faulty mains supply systems or excessive mains voltage can lead to electric shocks.

• All power supply or antenna systems connected to the loudspeaker must comply with all applicable laws and regulations and be professionally installed by an approved installation company.
• Use only the appropriate power cord to connect the speaker. Do not modify the power cord or its plug.
• Make sure that the mains voltage at your location matches the requirements of the loudspeaker! The correct power supply can be found on the label on the back of the speaker. It must not be connected to other power supplies.
• Devices of Class 1 construction must be connected to the mains power socket outlet with a protective earth connection. Make sure that the installation of the protective earth is carried out correctly!
• When laying the power cables, make sure that they cannot be damaged (e.g., by heating or mechanical stress)! Pay particular attention to the areas of the connectors and distributors!

Caution!

Overvoltage in the power supply system (e.g., due to lightning) can damage or destroy the device and power supply unit.

• An overvoltage protection element can provide a certain degree of protection against excessively high voltages in the power grid.
• The greatest possible protection against damage can only be achieved with the complete separation from the mains supply. In case of thunderstorms or danger of lightning strikes, disconnect the mains cable from the socket and any antenna plugs from your hi-fi system!
• If the speaker is not used for a long period of time or is unattended, the power supply should be disconnected. Disconnect the mains plug from the socket!

Care and Cleaning Tips

Caution!

Improper handling of the speaker may result in damage.

• Always unplug the speaker before cleaning it!
• Before recommissioning, make sure that all connections are correct, that there are no short circuits and that the speaker is completely dry.
• Never use strong cleaning agents or solvents such as petrol, spirit or similar!

Enclosure

We recommend commercial window cleaner sprayed onto a cotton cloth. This allows almost all fingerprints and dust to be easily removed. Alternatively, you can also use window active foam.

We advise against the use of microfibre cloths! These can cause mini scratches in the surface.

Diaphragms and Speaker Chassis

To remove dust from a loudspeaker chassis, a lint-free cotton cloth is sufficient to wipe the membrane lightly with very little pressure.
