i have previously used a Sigma BC 1200, worked great until water ingress got the better of connections, so splashed out on new Sigma BC 1606L, which is supposed to be backlit, but following instructions (i hasten to add this was a last resort..!) doesn't work, no problems with battery as it's brand new.
anyone else using one and got it lighting up?
the guide suggests holding both left hand side buttons, which should activate it? but no joy?
