Warranty Repair 

 

Call your Parasound dealer first. If the dealer can’t help you with your problem we encourage 
you to call Parasound’s Technical Service Department at 

415-397-7100

, Monday - Friday, 

8am- 4pm Pacific time. We can suggest other diagnostic tests you can easily perform. 
If we determine that your JC 3 Jr. should be returned to Parasound or an Authorized 
Parasound Warranty Center for inspection and possible servicing, we will provide the location 
of 
a warranty center near you or shipping instructions for the unit’s return to Parasound. Read 
your accompanying Parasound Limited Warranty carefully to understand the applicable 
rights and limitations. This section provides instructions for obtaining repairs, both for units 
covered 
under the Parasound Limited Warranty and for units or situations which are outside the 
Warranty. 

 
 
The JC 3 Jr. is not eligible for repair under the terms of the Parasound warranty if: 

 

1. The unit was not purchased from a Parasound Authorized Dealer. 
2. You do not have the original bill of sale or sales receipt from a Parasound Authorized 
Dealer. 
3. You are not the original owner. The Parasound warranty is not transferable. 
4. Unit’s serial number was removed, modified, or defaced. 
5. Unit shows evidence of abuse and/or misuse. 
6. Unit was modified in any way. 
7. A prior repair was attempted by an unauthorized repair station. 

 
 
 
Before You Return Any Unit to Parasound for Service 

 

 

Do not ship your JC 3 Jr. to Parasound without a Return Authorization (RA) number 
provided by our technical department. 

Before you send your unit to Parasound, you will 

need to obtain a specific Return Authorization (RA) number and shipping instructions from 
Parasound’s Technical Department. The RA number must be clearly marked on the outer 
carton. Use the original factory packing materials and arrange adequate insurance to cover 
its replacement value. You must include a copy of your purchase receipt, since this document 
establishes the validity of this unit’s warranty. Warranty repairs are only performed by 
Parasound or Parasound Authorized warranty centers when your purchase 
receipt is from a Parasound Authorized Dealer or Parasound Authorized Reseller.   
 
 

Note:

 Please do not ship to Parasound by the USPS (US Postal Service) 

- we will not accept delivery.  We will also refuse delivery of units whose 
cartons show evidence of damage caused by inadequate packing.
