Thanks Hunt, for your help. Dissapointed your post is missing. Glad I got the chance to read it once. Was going to print it for further evaluation, but it's gone. bill

Tried F11, nothing, then F7, nothing. Bachman info with eng says F1, which is strange as that should be the bell. Down loaded manual says CV52 controls brightness. Should I be chinging CV41? Some one with more expertese than I have will have to figure this out. This is my first Bachman engene and first tsumime systeme. Man! what happened to fun with model railroading. I have a stack at least 4" high of operating manuals from a number of different systems. Bill

No one having this problem but me? Re programed the acceleration and deacceleration to 100 each, and this engine is a blast to play with. Now, if only I could knock the brightness down. Instructions say I should be able to cut it in half with F1.  bill

Brand new to this form. Received my EM-1 this week, and it is one of the best running engine out of the box I have.  Feel the headlight is to bright but can't knock it down. CV 52 shows a range of 0 to 255 and defult of 64. Tried over and over to enter CV 52 to reduce brightness, but it wont take. Can change the address so I'm accessing the board. Am I missing something?  Bill
