General information
Never operate the loudspeaker unattended!

Nubert. If you need service, please contact Nubert electronic GmbH directly
Danger of suffocation!
Never let children use or play with neither speaker, remote control or packaging
unattended. There is a risk that children will get caught in the packaging film
and suffocate. Make sure that children cannot remove any small parts from the
devices! 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. Contact Nubert electronic GmbH
([email protected]) immediately!
• 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 per-
formance.
• The loudspeaker smells burnt, develops smoke or makes unusual noises.
Caution!
The drivers built into this loudspeaker generate a strong magnetic field in their
immediate vicinity, which can impair or damage other devices. It is therefore
essential to keep magnetically sensitive devices away from this loudspeaker! Do
not place tube screens, notebooks, hard disks or the like on the speaker!
Only use accessories recommended by Nubert!
Low temperatures and Sound
When speakers are shipped and delivered during the cold monthsof the year,
it is imperative that they adapt to the temperature of the living area. Low
temperatures have a considerable influence on the moving parts of a loud-
speaker such as diaphragm, voice coil,bead and spider. The ability of these
components to follow rapid oscillations or to perform large excursions is thus
significantly restricted.This is not dangerous, but “frozen” speakers are far
from their acoustic peak.
Hence our tip:
When your new speakers arrive on a cold winter’s day, just
give them a few hours to acclimatise. Your Nubert speakers will thank you with
the superior sound quality you have come to expect from us.
