Bowers & Wilkins 804 D3 [8/70] Running in

ENGLISH

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 rst 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.

6. Aftercare

The cabinet surfaces will usually only require dusting.

We recommend you use the cloth supplied with the

product. 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 rst, 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 nished

in real wood, the nest 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 rectied 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.
