• 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!

Remote Control and Battery

This product comes with a remote control and a battery. The following must be observed when handling remote controls and batteries:

• If the batteries are discharged, the range of the remote control will decrease significantly. If this happens, replace the batteries immediately.
• Always use high-quality CR2032 lithium button cells as replacement batteries. Make sure that the polarity is correct when inserting the battery into the battery compartment!

Caution!

Improper handling can lead to material damage.

• Do not drop the remote control!
• Do not expose the remote control and battery to water or other liquids!
• Do not operate or store the remote control and battery in locations with high humidity or high or low temperature!

Danger!

Leaking or exploding batteries can pose a health hazard and cause damage to goods.

• If you do not use the device for a long time or if the batteries are depleted, remove the batteries from the remote control to prevent discharge, leakage of acid, or explosions.

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.

The tweeters of all Nubert loudspeakers are equipped with a protective grille so that they can also be wiped off with low pressure. If the dust cannot be completely removed, a make-up brush from the drugstore is suitable.
