Terms of Sale

Terms are subject to change without prior notice.


Sine Systems, Inc. guarantees our products to be free from manufacturing defect for a period of one year from the original date of purchase from Sine Systems, Inc. This warranty covers the parts and labor necessary to repair the product to factory specifications.

This warranty does not cover damage by lightning, normal wear, misuse, neglect, improper installation, failure to follow instructions, accidents, alterations, unauthorized repair, damage during transit, fire, flood, tornado, hurricane or acts of God and/or nature.

Warranty Service

There is no charge for repair service on items covered under warranty. The customer is responsible for payment of shipping charges to return equipment to Sine Systems for service. Damage due to negligence, lightning or other acts of nature are not considered warranty issues.

Service Policy

Sine Systems offers same day repair service on all of our products. We repair and return products within 24 hours of arrival whenever it is feasible to do so. Because we offer immediate service, we do not provide loaner equipment. If we cannot immediately repair a product, we may offer other options at our discretion.

Sine Systems does not require prior authorization on repairs. See the factory repair service page for details on returning products for service. Sine Systems is not responsible for items lost in transport or delivered to an incorrect address.

Return Policy

This policy only applies to equipment purchased directly from Sine Systems, Inc. Equipment purchased through a third party vendor (dealer) is subject to the return policy of the vendor. Arrangements for return or exchange must be handled through the vendor.

Sine Systems policy on returns and exchanges with the factory is broken down according to the following schedule:

30 days

Items may be returned within thirty days from the date that they ship from our factory. Sine Systems will apply a full refund, less shipping charges, provided that the equipment is in new condition. There must be no cosmetic damage, all accessories must be included and unopened and all manuals must be included and undamaged. If any items are missing, damaged or opened, a 5% restocking fee will be applied.

60 days

Items may be returned within sixty days from the date that they ship from our factory. Sine Systems will apply 15% restocking fee. This fee covers the cost of returning the items to new condition, replacing accessories, replacing manuals and re-packaging. These items must eventually be sold as reconditioned instead of new.

Beyond 60 days

After sixty days, Sine Systems will recondition the equipment according to our repair policy but we will not accept it for return or exchange.
