SAFETY
INFORMATION
ON BERYLLIUM
MAINTENANCE
GUARANTEE
The Ex3ma tweeter contains Beryllium, a potentially
dangerous element: users are warmly invited to
carefully read the following safety information
to prevent any damage caused by the possible
absorption of the material.
The risk, however, is extremely limited when the
material is in solid form; greater danger and damage
occur when the product is inhaled or absorbed by
contact with micro-particle vapour.
1. SAFETY MEASURES
Beryllium must never come into contact with
abrasive material.
Avoid any type of contact with the skin or the eyes,
and do not inhale or swallow any part or all of the
beryllium dome. The producer highlights that the
absorption of beryllium by swallowing, inhalation
or cutaneous absorption can cause serious physical
problems because of its high level of toxicity for
humans.
The tweeter has a protective grille that must be never
removed.
Children must be generally kept away from the
drivers, and from the beryllium dome in particular.
2. IN CASE OF DAMAGE
Should the beryllium dome be damaged, we
recommend contacting Sonus faber immediately,
so that the assigned department can arrange the
removal and/or replacement of the dome.
Should the dome break, all the beryllium fragments
– if any - must be carefully collected and placed in
a plastic bag to be sealed hermetically. Immediately
contact Sonus faber for more information regarding
the sending and repair of the damaged part and of
the speaker.
Should beryllium be absorbed through the skin or
eyes, or if inhaled or swallowed, contact a doctor.
The speaker does not require any special
maintenance other than regular general cleaning. Do
not use products such as wax or detergents to clean
the wooden part of the cabinet, which could stain
or damage the wood or the drivers. We recommend
using a clean soft cloth (microfiber for example),
possibly slightly damp. Any dust on the unit, on the
front panels and the drivers must be removed using
a soft paintbrush, being very careful not to damage
their delicate membranes. Wood is a natural living
material that can be affected by environmental
conditions. We advise keeping the speakers distant
from heat sources or windows, in particular during
the summer months. We advise keeping the speakers
away from direct sunlight.
These simple guidelines will help keep your speaker
perfect for many years. Over time, the sound will
improve as a consequence of the running-in of
the moving parts of the speaker (membranes and
surrounds), while the acoustic enclosure will perform
better the more it is used – much like what happens
with acoustic string instruments!
The Ex3ma speakers by Sonus faber have been
designed and built following the highest quality
standards.
Should a fault or a malfunctioning occur, the
speakers are covered by guarantee. In such cases,
please contact Sonus faber directly; the company will
intervene quickly to solve the problem.
In addition, please note that:
•
speakers in need of repair should be returned in
their original packaging in order to be shipped
safely, together with a description of the
malfunction or defect the customer has noticed;
• the guarantee covers the speakers for any
construction faults as long as they have not
been disassembled, modified, tampered with
or used for purposes or in ways that are not
outlined in this manual.
