Maintaining Your ZoneMaster 450 

 

Your ZoneMaster 450 requires no periodic maintenance and has no user serviceable parts inside. 
To avoid risk of electric shock do not remove the top cover. To keep it clean use only a soft 
cloth moistened with a few drops of clear water or window cleaner. Never use any solvents or abrasives. 

 

 

 

Are You Having Difficulty? 

 
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 ZoneMaster 450 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. 

 
 
Unit is not eligible for repair under the terms of the Parasound warranty if: 

 

1. 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 

 

 

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.   
 
 

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.
