The old bike I recently bought came with a Sigma BC 300 fitted so I thought I might as well use it. It needed new batteries so I'm assuming that the wheel size has been reset and hence need to set it correctly. I cannot for the life of me figure out how to do this.

I've googled with all different terms but it seems the manual for this does not exist online. I found the BC 400's manual but the setting process doesn't seem to work for the older model.

From fiddling, the only thing I seem to be able to do is to select a number from 1 to 6 using the SET and SIZE buttons when the computer is in SPEED mode. Unless there are only 6 available wheel sizes (unlikely) I remain stumped.

Any help would be much appreciated.

Cheers,
Matthew
