5 Warranty and disclaimers

5.1 Disclaimer

Powersoft is not liable for any damage to speakers, amplifier, or any other equipment that is caused by negligence or
improper installation and/or use of the DIGAM amplifier.

5.2 Product warranty

Powersoft guarantees the DIGAM to be free from defective material and/or workmanship for a period of two year from
date of sale, and will replace defective parts and repair malfunctioning products under this warranty when the defect
occurs under normal installation and use - provided the unit is returned to our factory via prepaid transportation with proof
of purchase (sales receipt). This warranty provides that examination of the returned product must disclose, in our
judgment, a manufacturing defect. This warranty does not extend to any product that has been subject to misuse, neglect,
accident, improper installation, or where the date code has been removed or defaced.

6 Technical assistance and service

Servicing your unit requires a trained technician capable of performing the type of service you need. There are no user
serviceable components inside your unit and the danger of electric shock exists. Additionally, some of the components in
your unit are Powersoft specific parts that require Powersoft replacements.

6.1 Technical assistance

If you suspect that your amplifier is defective, check your system configuration and amplifier settings to determine the
origin of the problem. In many cases, incorrect audio interfacing, poor cabling, or other system level impairments are the
cause of problems in audio systems. For technical assistance beyond the information given in this manual, the Powersoft
technical Services department may be contacted.

6.2 Factory service

In the event that your amplifier does need factory service, you may reach the Powersoft Technical Services department for
return instructions. A Return Authorization (RA) number must be obtained from Powersoft Technical Services department.
Powersoft may not account for products that are returned without a Return Authorization number.

Pack the product well for protection during shipment.
Include a copy of sales receipt, your name, return address, phone number and defect description with your return
correspondence.
Call the Powersoft Technical Autorization Services department for an outside of the packaging.
Ship the product prepaired to Powersoft. We recommend United Parcel Service (UPS).
