Housing

We recommend using a standard glass cleaner sprayed onto a cotton cloth. This allows most fingerprints and dirt to be removed easily. Alternatively, you can use window active foam. We advise against using microfiber cloths as they may cause micro-scratches on the surface.

Membranes and Speaker Drivers

To remove dust from a speaker driver, use a lint-free cotton cloth and gently wipe the membrane with very light pressure. All Nubert speakers' tweeters are protected by a grille, which can also be wiped lightly with minimal pressure. If the dust cannot be completely removed, a makeup brush from the drugstore can be used.

Warning!

Power surges in the electrical system (e.g., due to lightning strikes) can damage or destroy the device and power supply

• A surge protection device can offer some protection against excessively high voltages in the power grid.
• The greatest protection against damage is complete disconnection of your devices from the power and antenna systems. Therefore, during thunderstorms or risk of lightning strikes, unplug the power cord and any antenna connectors from your hi-fi system!
• If the speaker is not used for an extended period or is left unattended, the power supply should be interrupted. Unplug the power cord from the socket!
