Hafler DH-110 manual Service Policy And Limited Warranty, PC13, OC2$, c130

SERVICE POLICY AND LIMITED WARRANTY

Your DH-110 Preamplifier has been carefully engineered to provide many years of use without maintenance or ser- vice. Factory assembled units undergo many physical and electrical tests before shipment. The circuit board in kits is similarly tested to meet all primary specifications before it is packed. Nevertheless, shipping damage can occur, or human error may intervene to make service necessary.

Because many of the components in this refined design are not readily available, and because substitution of apparently similar parts can easily compromise its perfor- mance, we strongly recommend that you make use of our complete factory service facilities, or order exact re- placement parts from the factory.

It is the owner’s responsibility to return the unit, freight prepaid, to the factory service facility. Units shipped freight collect will not be accepted. Shipment should be made via United Parcel Service whenever possible. We will not be responsible for damage caused by parcel post shipment; repairs in this case will be made solely at the owner’s expense. Be sure you insure for the full value of an assembled unit.

Use the original carton and packing materials, and en- close all of the following:

1.Complete shipping address (Post Office Box numbers are not acceptable for UPS return)

2 . Serial number (if not on the unit).

3 . Copy of dated bill of sale (for service under warranty)

4.Description of malfunction. If it is intermittent, please indicate this.

5 . You may also wish to attach your address directly to the unit, or to the line cord.

All service work is guaranteed for 90 days.

Warranties apply only to the original purchaser, and are void if the Preamplifier has been modified without factory authorization, or if parts have been substituted which, in the factory’s opinion, are not suitable, or if the Pre- amplifier has been physically or electrically abused or used for some purpose for which it was not designed or in- tended.

Technical assistance to help you locate the source of a problem may be obtained by calling the Hafler Company Technical Service Department at 609-662-6084 between 8 am and 4:30 pm, eastern time. It will be helpful to know the serial number, and the results of any tests you have per- formed. However we do not recommend that you attempt your own servicing unless you are knowledgeable in this regard. If you return a properly functioning Preamplifier for service or a checkout, a charge will be made for the checkout time required, as well as for packing and ship- ping.

WARRANTY FOR FACTORY ASSEMBLED UNITS

The assembled DH-110 is warranted for three years from the purchase date, including parts, labor and normal return shipping costs from the factory to the owner within the continental United States. The owner is responsible for shipment to the factory and must submit a copy of the dated bill of sale.

WARRANTY FOR KIT-BUILT UNITS

The parts in a DH-110 kit are warranted for a full year from the purchase date. If a defective component is found on a circuit board or in the kit, simply return the individual part to the factory prepaid, together with the serial number and the date of purchase. It will be replaced at no charge.

If you cannot locate the cause of a problem in your DH- 110, return it to the factory along with a copy of the dated bill of sale, and a check for $30. If the difficulty is solely a defective part, the unit will be returned to you prepaid, and your $30 less shipping and packing charges will be re- turned to you. If the problem is found to be an error in your assembly of the kit, the unit will be put in proper working order and returned to you prepaid.

This warranty is void if the kit has not been completely assembled, or if other than rosin core solder has been used. Units assembled with acid core or silver solder, or paste flux, will be returned unserviced.

This warranty gives you certain rights. You may also have other rights which vary from state to state.
