We strongly recommend that you keep notes on which settings you have changed and
which values were used. If you ever need to do a reset on the decoder (see “Factory
Reset” below) then having good notes will allow you to easily re-enter any changes that
you wish to keep.
— VERY IMPORTANT —
Before you manually change any of the volume control CVs, you must set CV
31 to 16 and then CV 32 to 1. CV 31 and CV 32 are used as index selection
registers and if you don’t set them first, unspeakable things may happen to your
unit. You must set the CVs every time before changing any volume CV setting. Or
just use a LokProgrammer.

FACTORY RESET
On your RS-18, you can perform a factory reset by entering a value of “8” into CV 8.
Note that this will cause all of your new volume and motor settings to be lost, so you will
need to reprogram any settings that you want to keep. What do you mean, you didn’t
take any notes? WE JUST TOLD YOU TAKE NOTES. You’re out of the band. Again!
You can NOT lose all of the pre-recorded sounds on your RS-18 decoder by doing a
factory reset. However, after performing a factory reset your RS-18 may begin to sound
like Foster Hewitt calling a Maple Leafs game. If that happens, you have probably lost
your mind. We also don’t know how to change it to Dick Irvin calling a Canadiens game
either. But don’t worry. Just sit back, grab some popcorn and enjoy the game. Pay no
attention to the person breaking into your layout room attempting to steal your Rapido
RS-18 because they misread the instructions on Page 4.
