We are sorry to hear that our product isn't working as promised. Sometimes we can solve problems over the phone with software updates or resets, so the first thing to do is give us a call or send us an email.
If we decide that the problem can't be solved over the phone, we will ask you to fill out a return material authorization. This is an electronic form (link) on this site. If you have just taken delivery of a new product that has failed, we might have you return it directly to the retailer. If we ask you to ship a warranty repair back to us, we will provide shipping instructions in email. Please don't ship anything to us at FLIR without first talking with us and getting a return material authorization number. Without this, we could lose track of your shipment and it can delay repairs. All FLIR outdoor and tactical equipment is designed to take the abuse of the mission, and we stand behind our warranty promise and take customer satisfaction seriously.

Be sure to keep a copy of your purchase receipt and register your product. You can read FLIR's Outdoor and Tactical Warranty here.
