8 Service

Crown amplifiers are quality units that rarely require servicing. Before returning your unit for servicing, please contact Crown Factory Ser- vice to verify the need for servicing.

This unit has very sophisticated circuitry which should only be serviced by a fully trained tech- nician. This is one reason why each unit bears the following label:

CAUTION: To prevent electric shock, do not remove covers. No user serviceable parts inside. Refer servicing to a quali- fied technician.

8.1 Worldwide Service

Service may be obtained from an authorized service center. (Contact your local Crown/ Amcron representative or our office for a list of authorized service centers.) To obtain service, simply present the bill of sale as proof of pur- chase along with the defective unit to an autho- rized service center. They will handle the necessary paperwork and repair.

Remember to transport your unit in the original factory pack.

8.2 US and Canada Service

Service may be obtained in one of two ways: from an authorized service center or from the factory. You may choose either. It is important that you have your copy of the bill of sale as your proof of purchase.

8.2.1Service at a US or Canada Service Center

This method usually saves the most time and effort. Simply present your bill of sale along with the defective unit to an authorized service center to obtain service. They will handle the necessary paperwork and repair. Remember to transport the unit in the original factory pack. A list of authorized service centers in your area can be obtained from the Crown website at www.crownaudio.com, or by calling Crown Factory Service.

8.2.2 Factory Service

To obtain factory service, fill out the service information page found in the back of this man- ual and send it along with your proof of pur- chase and the defective unit to the Crown factory.

For warranty service, we will pay for ground shipping both ways in the United States. Con- tact Crown Factory Service to obtain prepaid shipping labels prior to sending the unit. Or, if you prefer, you may prepay the cost of ship- ping, and Crown will reimburse you. Send cop- ies of the shipping receipts to Crown Factory Service to receive reimbursement.

Your repaired unit will be returned via UPS ground. Please contact us if other arrange- ments are required.

8.2.3Factory Service Shipping Instructions:

1.Before sending a Crown product to the factory for service, first call the Crown Factory Service for a return authorization (RA) number.

2.Be sure to fill out the service information form that follows and enclose it with your shipment, either inside the box or in a packing slip envelope securely attached to the outside of the shipping carton. Do not send the service information form sepa- rately. If you are sending the unit from a Shipping Center, we recommend taping the form to the product. We also recom- mend recording the serial number and model before shipping for your reference.

3.To ensure the safe transportation of your unit to the factory, ship it in an original factory packing container. If you don't have the original carton, you may obtain a prod- uct service foam-in-place shipping pack from the Crown Factory Service at the number listed below. For non-warranty service, you may also provide your own

shipping pack, however we still recom- mend using a Crown Supplied Shipping Container. Minimum recommended requirements for materials are as follows: 275 P.S.I. burst test Double-Wall carton that allows for 2-inch solid Styrofoam on all six sides of unit or 3 inches of plastic bubble wrap on all six sides of unit; securely seal the package with an adequate carton sealing tape. Do not use light boxes or "peanuts." Damage caused by poor packing cannot be covered under warranty.

4.Do not ship the unit in any kind of cabinet (wood or metal). Ignoring this warning may result in extensive damage to the unit and the cabinet. Accessories are not needed-do not send the product documen- tation, cables and other hardware.
