Okay call me stupid and computer illiterate but trying to free up space on the HC2 I followed the instructions in the illustrated guide Storage Memory & Deleting. Now I only deleted one sound file that was a sound and the Locomotive now has no bell. I was under the assumption that the sounds were stored on the LM3S and would remain there for use. Am I not understanding something here? All I wanted to do was free up memory space on the HC2 which I did,about 1% but the sound is gone on the Locomotive. Please help this old man with this issue. Thanks in advance. Before someone asks there are presently 15 Locomotives with sound, lights etc. on the HC2. Dave
