HELP PROGRAMMING THE DIGITRAX ZEPHYR EXTRA

[darticus]

Have my xmas gift up and running. Can't figure out how to get to the section in the digitrax to change the locos volume. The loco Walthers Y3 says it in CV 51, I think, but I don't know how to get to CV 51. Anyone able to get me started in programing. The manual sound like a foreign language. Maybe with a little help I can get going. Thanks Ron
