Ive been trying to register the warranty on my sansa fuze and it requires both a serial # and product #. However, in the back of the battery area there is only one number avaliable. which number would this be and where can i find the other one .
The number on the decal on the back of the device is a batch production number that will suffice for warranty.
If you are feeling froggy, connect in MTP mode to the PC. Find the Sansa Fuze in My Computer / Computer, and right click on the device. Select Properties.
The device serial number is the first 16 digits of the 32 digit string.
