Can I reset my DCC decoder to factory settings?

Sometimes, us mere mortals completely forget what values we have set to our decoders, other times our decoders just start to misbehave for no reason whatsoever. When the latter happens it's easy for panic to set in as it can appear that your decoder has somehow become defective. Fortunately, this is rarely the case and often the problem is simply caused by a power interruption throwing your settings out and can be easily sorted with a decoder reset.

The exact process for resetting your decoder will vary from brand to brand so a quick referral to your decoder's instructions or a check on the Internet will be necessary, but the process will in most cases involve setting a specific value to CV8 (usually it is the value 8 but check your decoder's instructions) followed by a signal to execute which again in a lot of cases involves little more than removing your locomotive from the track momentarily.

Once this is all done, your decoder will be returned to its factory settings, including all CV values like acceleration rate. It will therefore answer to address number 3 on your controller and you're free to start reprogramming your locomotive from scratch.

So try not to worry if your decoder seemingly develops a mind of its own, there's a lot to be said for the old saying "have you tried switching it off then on again?"
