I'm sitting here on my first maintenance expedition, which is a pretty scary thing.
Last sat night after a great dive we reached the cavern zone, and I went to change the setpoint and my confirm button didn't work. I stood on my head. gave it the universal sign but nothing made it allow me to change setpoint.
by the way I read the threads on this in here so I twiddled it around and it works now!!!
I figured I need to change the button, so I got one in one day believe it or not from fill express. The handset has a big scratch on it so I got a new handset lens at the same time (figured i might as well)
anyhow, now I'm stuck wondering how to change the lens. I have lots
of fancy little star shaped bits but not a single one that fits the screws

... if i'm not supposed to take it off then how come I can buy a new one.
any advice for a freaked out first time service tech would be helpful
