Operation Manual

Crown mixers are quality units that rarely require 
servic ing. Before returning your unit for servicing, 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 qualifi ed 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.

purchase along with the defective unit to an authorized 
service center. They will handle the necessary paperwork
