6. Faults / Fuses / Maintenance

There are internal secondary (low voltage) fuses on some internal supply rails.

In the event of failure the unit MUST BE DISCONNECTED FROM THE MAINS

SUPPLY BEFORE REMOVING THE UNIT COVER. The fuses should be

replaced with the same type only. THIS SHOULD BE CARRIED OUT BY

QUALIFIED PERSONS ONLY.

WARNING:

If the replaced fuse blows again then there is a serious fault within the unit.

Refer to a service engineer or contact your dealer. NEVER INCREASE THE

RATING OF THE FUSE.

ENSURE THAT ELECTRICAL POWER TO THE UNIT IS DISCONNECTED

BEFORE CARRYING OUT ANY MAINTENANCE.

NOTE:

The filter between the air intake (frontplate) and the frontpanel of the B1500 & B2000

amplifiers should be cleaned or replaced periodically, e.g. 12-24 months. (Filters in

amplifiers located in more 'dirty' atmospheres may require more frequent

maintenance). No special tools are required to remove the filters. The filter should be

'dry' cleaned, using a vacuum cleaner preferably. Running the amplifier without a

filter is not recommended. Replacement filter material is available.

No other regular maintenance is required.

If you have any doubt about carrying out this procedure, refer to a qualified

service engineer or contact your Bose ProPartner.
