Precautions
Special precautions regarding
the Beryllium dome tweeter
In its solid form, Beryllium is harm-
less. However, due to its nature,
certain special precautions should
be observed to avoid exposure to
unnecessary risk.
• Under no circumstances the
Beryllium dome should be subjected
to any form of abrasive action. To
ensure no accidental damage to the
tweeter dome it is advised to carefully
replace the protection cover.
• In the unlikely case of damage to
the dome, of any form, the supplied
piece of adhesive tape should be
immediately used to seal the whole
front surface of the tweeter. The
protective cover should then be
replaced and also taped securely
in place. You should then inform the
dealer from whom you purchased
the product so that the tweeter can
be removed by a professional and
returned to the product distributor
for replacement.
• If the dome is broken in any way
giving rise to loose particles of
Beryllium, they should be carefully
collected with the use of a supplied
adhesive tape and sealed in a zip-
top bag to be returned with the
tweeter.

Warning
Continued listening at high volume
levels above 110dB, can damage
your hearing durably. Listening
above 130dB can damage your
hearing permently.
Running-in period
The drivers used in the Uopia
Be Line are made up of complex
mechanical elements and requires
an adaptation period before they
deliver their full potential. They must
get adapted to the temperature
and humidity conditions of their
environment. This running-in period
depends on the encountered con-
ditions and can last several weeks.
In order to shorten this period,
we advise you to let your speaker
operate for about twenty hours at
medium level, playing standard
music programs, but with a large
amount of bass. Once the com-
ponents of the speaker are com-
pletely stabilized, it is possible to
enjoy the real performances of your
speakers.
