If All Else Fails –Call Us for Help

Call your Parasound dealer or Parasound’s Technical Service Department toll free at 1-866-770-TECH (8324). We can often solve the problem with simple diagnostic tests you can perform yourself. If we determine that your A 23 will need further inspection or servicing, we will:

a)refer you to an authorized Parasound repair center near you, or

b)authorize return of the unit to us and advise you of the correct procedure.

Procedure for Returning Your A 23 to Parasound for Service

If Parasound determines that you should send your A 23 to Parasound, you will be given a Return Authorization (RA) number. This RA number must be clearly marked on the outer carton only.

IMPORTANT: Enclose a copy of your original purchase receipt. A unit is eligible for warranty repair ONLY when the purchase receipt shows that the unit was purchased from an Authorized Parasound Dealer. A unit obtained through unauthorized channels is not eligible for warranty repair. Parasound is not responsible for any sellers’ misrepresentations about our warranties or other service policies.

We do not accept any of the following:

Units with collect shipping charges

Units without a valid RA number

Units without a suitable shipping carton

Units for which we see or hear evidence of improper packing

For a non-warranty repair, contact us for an estimate of the repair charges before you ship the unit to us. The same packing and Return Authorization number procedures apply.

Important Notice - Shipping the A 23

Before shipping the unit to Parasound, you MUST re-pack the unit into its fitted molded foam insert sandwich and its original carton. If you do not have the original packing cartons and foam inserts, call us for new packing materials that we can provide to you for a nominal charge. Use of any other carton and packing materials will probably result in shipping damage, and refusal of the unit. Common carriers such as UPS seldom pay claims for damage incurred during shipment when a product is surrounded only with Styrofoam "peanuts" or otherwise improperly packed.

We cannot stress enough the importance of properly packing your A 23. Shipping damage resulting from inadequate packing can cost you a lot of money and significantly increase the time required for repair.

Ship the unit with adequate insurance. After repair under warranty, the unit will be returned to you via prepaid UPS within the continental United States.
