I've got a d9 that I picked up from Trademe at a bargain price. It's working great except that I can't hear any of the audible alarms underwater. When I put it in dive mode I hear it chime when on the surface but I've never heard the ascent rate alarm or the low O2 (via wireless gas monitoring) alarms. Can anyone else with the same watch tell me if they have this issue? I'm wondering if I need to take it for repair (or get my hearing checked!)
I don't plan to rely on the audible alarms but I would have been disappointed if the watch was faulty. It sounds like it's not. Why bother even having audible alarms if they are inaudible underwater? That being said I've heard many other diver's computers beeping away - maybe the d9 is quieter than most! No noise pollution from me!
