General Warranty

We warrant most new products against defects in workmanship for one year (see “Exceptions” below) from the date they are placed in service. Defective components may be returned prepaid / insured to us for repair or replacement at no additional charge during that one-year warranty period. However, damage that occurred after delivery to the customer, such as from lightning or other physical, electrical/digital sources, including improper use or abuse, is not covered by this warranty; and the warranty is void should the configuration of components, hardware or software, including the total system, be modified (or modified with respect to the operating environment) subsequent to delivery.
Warranty Extensions

Our general warranty may be extended beyond one year for an annual charge. Service contracts are available after expiration of the warranty period that provide for prompt repair and replacement of defective components in the field. Inquire for pricing.

Also, customers may purchase repair parts from us directly. Beforehand, we might suggest diagnostic equipment they can use to identify defective components, which, typically, they would remove and return to us for immediate replacement or repair.
