SERVICE

We recommend that if at all possible, a BBE DI-400 which requires service be sent to our facility in Huntington Beach, California. We request that a “RETURN AUTHORIZATION” be issued by the dealer from whom you purchased the unit. If this is not possible, call BBE Sound, Inc. directly at (800) 233-8346, extension 116 to obtain a “RETURN AUTHORIZATION.” Include a copy of the bill of sale with the unit when it is shipped to BBE Sound, Inc. so that the service can be expedited.

As the repair turnaround time is minimal, we request that the unit be sent to BBE Sound, Inc. We also need to add reliability data to our files so that future revision may be undertaken, if necessary, to improve the product.

If unit has been purchased outside the US, please contact your national distributor.

MAINTENANCE

Maintenance of the BBE DI-400 is limited to proper cleaning of the unit with mild household cleaner such as Formula 409™ or Windex™. The chassis is steel , the casing is an aluminum extrusion. Both are finished with a durable polyurethane paint.

There are no user replaceable parts and the unit should not be opened for any reason unless you are a qualified technician. Calibration should be performed if parts are

replaced or if a performance check-out indicates a problem with calibration. Long term use has shown that over the life of this unit there is little or no drift of the components in the BBE DI-400 which would cause a change in calibration.
