User Manual

6.0 RuNNING-IN

You should expect the sound quality from your new subwoofer to gradually improve during the

initial period of use. Nothing particular has to be done in order to run in the subwoofer – but

expect up to 100 hours of playback (depending on playback level) before full performance level

is reached. Use normal music for running-in the subwoofer.

7.0 OVERLOADING

If DALI SUB C-8 D is overloaded, the built-in safety circuit may power down the subwoofer. The

subwoofer will power on again when the temperature of the built-in ampliﬁer is within safe

working range. If overloaded, we recommend that you turn off the subwoofer for a few minutes

before turning it on again.

NOTE: The built-in safety circuit is no guarantee against damage as a result of overloading.

8.0 MAINTENANCE

Cleaning the subwoofer surfaces can be done with ordinary household cleaning agents and

using a micro ﬁbre cloth. Avoid using products that are abrasive or contains acid, alkali or anti-

bacterial agents. Avoid using aerosols. Avoid using cleaning agents directly on the drive unit

and clean it with extreme care.

8.1 AVOID DIRECT SUNLIGHT

The surfaces of the subwoofer may fade or become discoloured over time when exposed to

direct sunlight. Therefore avoid positioning the subwoofer in direct sunlight.

9.0 DISPOSAL

DALI products are designed to meet the international directives concerning Restriction of

Hazardous Substances (RoHS) and disposal of Waste Electrical and Electronic Equipment

(WEEE). The waste symbol indicates that the subwoofer meet the directives. The subwoofer

must be processed or recycled appropriately. Please consult your local waste authority for

guidance.
