To be able to provide you with the correct support information, we need to determine your product version. Please check the sticker on the bottom of your product (as shown on the photo) and select your version from the links below. The firmware MUST ONLY be used with the corresponding device. It is not designed to work on different hardware versions. Attempting an upgrade with the wrong version of firmware for your product could render your equipment inoperable, and will invalidate your product's warranty.
