VII. TECHNICAL ASSISTANCE & SERVICE
Servicing your QSC product requires a trained and qualified technician. There are no user serviceable components inside, and the danger of
electric shock exists. Additionally, some of the components are QSC-specific parts that require QSC replacements. Comprehensive service
manuals for most models are available from QSC.
Technical Assistance
If you suspect that your UF-3 is defective, check your system configuration and UF-3 settings to determine the origin of the problem. Incorrect
audio interfacing, poor cabling, or other system-level impairments are the leading causes of problems in audio systems. For technical assistance
beyond the information given in this manual, contact QSC Technical Services.
Factory Service
If your UF-3 needs factory service, contact QSC Technical Services for instructions and a Return Authorization (RA) number. QSC cannot be held
responsible for products that are returned without a Return Authorization.
Product Return Guidelines
1. Pack the product well for protection during shipment. QSC will provide factory packaging upon request, free of charge.
2. Include a copy of the sales receipt, your name, return address, phone number, and defect description with your return correspondence.
3. Call or e-mail QSC Technical Services for a Return Authorization number. Have the product’s model number and serial number, as well
as your shipping and telephone information ready at hand.
4. Mark the Return Authorization number on the outside of the packaging.
5. Ship the product prepaid to QSC Audio Products. We recommend United Parcel Service (UPS).
