ENGLISH
The cabinet surfaces will usually only require dusting. We
recommend you use a soft microfibre cloth. If you wish to use
an aerosol or other cleaner, apply the cleaner onto the cloth, not
directly onto the product, and test a small area first, as some
cleaning products may damage some of the surfaces. Avoid
products that are abrasive, or contain acid, alkali or
anti-bacterial agents. Do not use cleaning agents on the drive
units. Avoid touching the drive units as damage may result.
Whenever Bowers & Wilkins speakers are finished in real wood,
the finest veneers are selected and treated with an ultra-violet
resistant lacquer to minimise changes in colour over time.
Nevertheless, like all natural materials, the veneer will respond to
its environment and a degree of colour change is to be expected.
Colour differences may be rectified by exposing all the veneer
surfaces equally and evenly to sunlight until the colour is uniform.
This process can take several days or even weeks, but may be
accelerated by careful use of an ultra-violet lamp. Wood veneered
surfaces should also be kept away from direct sources of heat
such as radiators and warm air vents in order to minimise the
possibility of the wood veneer cracking.
The tweeter housing has a textured finish that may collect
superficial marks when handled. It can be cleaned by wiping a
soft microfibre cloth around the housing, in line with the surface
texture.
The performance of the speaker will change subtly during the
initial listening period. If the speaker has been stored in a cold
environment, the damping compounds and suspension materials
of the drive units will take some time to recover their correct
mechanical properties. The drive unit suspensions will also loosen
up during the first hours of use. The time taken for the speaker to
achieve its intended performance will vary depending on previous
storage conditions and how it is used. As a guide, allow up to
a week for the temperature effects to stabilise and 15 hours of
average use for the mechanical parts to attain their intended
design characteristics.
