Sorry, I forgot to add.

I am running it on DCC and yes, I have reset the decoder before, but it does it regardless.

Hello,

I have an RS-3 (63902) with the SoundValue on board. When I have the sound on and change the direction of the loco, the sound mutes until I apply some throttle again.
How can this be changed, so that the sound stays on when changing direction?

Well it was F4 before I reset the decoder.

Ok, I've just reset the decoder and Rule 17 works now. And the headlights aren't as blinding anymore. But F4 dimming doesn't work anymore...

Thanks for the replies.
I did not ask if I should dim the headlights, but if I could.

F8 is indeed for Mute. Dimming is F4, but even then it's still massively bright. The reason I am asking if it's possible is because I saw other people's RS-3s (yes, Bachmann stock ones) which had much dimmer headlights.

I'll just solder a resistor to the LEDs if the Decoder doesn't support further dimming.
Does the RS-3 have the Rule 17 dimming? Because mine doesn't. The headlights stay the same brightness in either direction.

Hello,

I have the CP #8438 of the RS-3 with a SoundValue decoder installed. I like it very much, but the headlights are far too bright. They light up the entire room and even with the Dimmer function switched on, it's still too bright.

Which CV controls the brightness? I have the list of CVs from the Website, but none refer to the brightness.
