Connection Instructions

General Connection Instructions

• Unplug all devices in your system from the power supply before making any wiring changes!
• Ensure that all connections are made correctly and that all plugs are firmly seated in their sockets before reconnecting the devices to the power supply!
• Only use the designated cables and connectors for connections! Otherwise, damage or malfunctions may occur.
• When disconnecting the speaker, always pull on the plug, not the cable!
• Ensure that all plugs are securely seated in their sockets!
• Only use cables and accessories recommended by Nubert!

Caution!

Disconnect your amplifier/receiver from the power supply before connecting your speakers! Refer to the amplifier/receiver's user manual for instructions on connecting speaker cables.

Care and Cleaning Tips

Caution!

Improper handling of the speaker may cause damage.

• Always unplug the power cord before cleaning the speaker!
• Ensure that all connections are correct, there are no short circuits, and the speaker is completely dry before resuming operation.
• Do not use harsh cleaning agents or solvents such as gasoline, alcohol, or similar substances!

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.

Your device is intended for use in dry indoor environments. If you exceptionally operate the device outdoors, please ensure that it is protected from moisture (rain, water splashes, condensation).

Do not expose the TV set to dripping or splashing water (e.g. rain)!

Disconnect the mains plug before cleaning the device!

Do not hold the remote control directly in front of your eyes while pressing a button! Infrared light!

The television may only be operated with a mains voltage of 230–240 V~ 50 Hz.

For maintenance and servicing work, the mains plug or the appliance-side connector of the TV's power cord must, in accordance with the applicable standard, be regarded as and kept usable as the means of disconnecting the device from the mains supply.

Candles and other open flames must be kept away from this product at all times to prevent the spread of fire.

Opening the device and carrying out repairs must only be performed by qualified personnel. DANGER TO LIFE! Please contact your specialist dealer if repairs are required.

Bluetooth® devices operate using short-range radio signals. Under certain circumstances, these signals may interfere with the operation of other electronic devices and medical equipment.

Radio waves may affect the operation of pacemakers and other medical devices. Maintain a minimum distance of 20 cm!

Never spray cleaning fluid directly onto the screen surface! If cleaning fluid penetrates the lower frame of the screen, the components located there will be irreparably damaged.

The remote control is supplied with two LR03/AM4/AAA 1.5 V micro batteries. If a battery is swallowed, it can cause serious internal injuries within 2 hours, which may be fatal. If you suspect that batteries may have been swallowed or inserted into any part of the body, seek immediate medical attention. Keep new and used batteries out of the reach of children.

Metz Classic devices with a 3-pin IEC mains connector are internally designed as Class II devices with reinforced insulation. Therefore, the protective earth conductor is not connected within the device. One reason for this design is the prevention of ground loops.

• Do not insert rechargeable batteries into the remote control battery compartment. Only two LR03/AM4/AAA 1.5 V micro batteries may be used.
• A cold device may only be put into operation in a warm room once any condensation that may have formed on the screen surface has completely evaporated.
• Televisions require adequate cooling. The openings in the rear panel must not be covered by curtains or similar objects. The ventilation slots on the underside of the device must remain unobstructed, as the device draws cooling air through them.
• Ensure sufficient airflow for cooling if the device is installed in a cabinet.
• Do not place or mount the device directly next to or above a heater, as this may impair cooling performance.
• Do not place burning candles or containers filled with liquid on or above the TV set. Hot wax and liquids entering the interior of the device will damage the electrical components of the TV. In such cases, the electrical safety of the device can no longer be guaranteed.
• Thunderstorms pose a danger to electrical devices. A lightning strike on the power line or antenna can damage the device, even if it is switched off. During thunderstorms, disconnect the mains plug and antenna plug from the wall outlet and from the television.
• The TV set is intended exclusively for the reception and playback of audio and video signals.
• Do not display still images, logos, images with border bars, or similar content for extended periods. There is a risk that such static images may leave permanent marks on the screen.
• Soot and dust deposits may accumulate behind the TV panel glass even when no visible source of soot is present. Such deposits are also referred to as “fogging” or “magic dust.” This phenomenon may occur occasionally, particularly during the heating season, after renovation work, or in new buildings. Various factors are considered possible causes; further information can be found in reports available online. Cleaning or replacement of the panel in such cases is excluded from warranty claims, as this is not a defect of the device but the result of external influences.
• The screen surface must be cleaned using a dry, soft cleaning cloth (e.g. a microfiber cloth).
• If heavier soiling has nevertheless occurred, the screen surface may be cleaned using a slightly damp, soft cloth; see also Chapter 37.
