KB548: TF4 - Reset CVs to factory default

This article was last updated on Nov. 28, 2011, 3:18 p.m. | Print Article | Leave Feedback

Q: What is the exact reset procedure for a TF4? I tried both with series 3 procedure (CV8) and the other mobile decoders procedure with no success. My TF4 remains out of control. However, the white output makes the LED on my decoder testing board flicker.

A: Since CV8 to 08 only works on series 3 and later decoders, it does not work on the function only decoders. TF4's CVs must be reset manually to factory values. The Factory Default Values are:
CV64 000
CV61 002
CV49 000
CV50 000
