Hello, I am hoping that someone here can help me out. I have a TK-290 radio with serial number 10800xxx. The problem I am having is that I am trying to update the firmware with the 608F, but the radio says that it has 1EB9 in it. I know the serial number says it should be the 608F according to the LSB 0260, but that isn't what is in the radio. Am I reading the wrong set of numbers for the serial number? Help please.
Mike
