Operation Manual

9 Service

Crown amplifiers are quality units that rarely require 

ser vicing. Before returning your unit for service, please 

con tact Crown Technical Support to verify the need for 

servicing.
This unit has very sophisticated circuitry which should 

only be serviced by a fully trained technician. 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 qualified technician.

Complete the Crown Audio Factory Service Information 

form, in the back of this manual, when returning a Crown 

product to the factory or authorized service center. The 

form must be included with your product inside the box or 

in a packing slip envelope securely attached to the outside 

of the shipping carton. Do not send this form separately. 

Warranty is only valid within the country in which the 

product is purchased.

9.1 International and Canada Service

Service may be obtained from an authorized service 

cen ter. (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 

purchase along with the defective unit to an authorized 

service center. They will handle the necessary paperwork

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.

9.2.1 Service at a US Service Center

This method usually saves the most time and effort. 

Sim ply 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. 

Remem ber to transport the unit in the original factory 

pack. A list of authorized service centers in your area can

1.  Fill out and include the Crown Audio Factory Ser vice 

Information sheet in the back of this manual.

2.  Do not ship any accessories (manuals, cords, 

hard ware, etc.) with your unit. These items are not 

needed to service your product. We will not be 

responsibility for these items.

3.  When shipping your Crown product, it is important 

that it has adequate protection. We recommend you

product for repair. If you do not have the original box,

and order new pack material. See instructions for 

“foam-in-place” shipping pack. (Do not ship your

recommended requirements for materials are as 

follows:

 a.  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.

b.  Securely seal the package with an adequate carton 

sealing tape.

c.     Do not use light boxes or “peanuts”. Damage caused 

by poor packaging will not be covered under 

war ranty.

Using your ‘foam-in-place’ shipping pack

Note: The foam-in-place packing is molded so that there 
is only one correct position for your product. 

  1.  Open carton and lift center cushion leaving both end-

cushions in place.

2.  Carefully place your product with the product’s front 

panel facing the same direction as arrows indicate.

3.  Reset center cushion down over top of product’s 

chassis. The foam-in-place packing was molded to 

accommodate different chassis depth sizes. If your 

product’s chassis does not completely fill the foam-

in-place cavity, you may use a soft but solid packing 

material (such as paper or bubble wrap) behind the 

chassis.

4.  Enclose the completed Crown Audio Factory Service

of carton) and re-seal the shipping pack with a sturdy 

carton sealing tape.

9.2.6 Payment of Non-Warranty Repairs

Payment on out-of-waranty repairs must be received 
within 30 days of the repair date. Units unclaimed after 30 
days become the property of Crown Audio Inc.
