For digital sound, be sure a coaxial
or

you are using Digital programming, verify that the settings are correct at the
receiver. Be sure the source material
(DVD,

or
broadcast pro-
gramming)
is
Dolby Digital encoded.

Cleaning
the
speakers
The cabinets

your Acoustimass 15 speaker system may be cleaned with a soft
damp

Do not use any sprays near the system

allow liquids
to
spill into any openings. Also,
do
not
use any solvents, chemicals,
or
cleaning solutions containing alcohol, ammonia,

abrasives.
The grille assemblies on the cube arrays may be carefully vacuumed, if necessary. Please
