vision software problem(again?)

windymiller

Oh no, another thread on vision failures!

Ok, havent used my unit since late october and been stored inside house..

I switched it on last week, everything fine..off to do my first dive in a while 2moro so was putting kit together and did pressure tests on lungs.

Switched on handset and things went pretty bad!

Immediately, the HUD flashed red and the buzzer sounded, screen was blank and nothing happened...apart from constant beeping!

Took the head off and removed and replaced both batteries.

Switched it on and it powered up fine...then the buzzer started, the HUD flashed, the solenoid constantly fired and I was told, low oxygen, missed deco, CNS% 255%, 1092 hours since reset!

Unit wouldnt power down so I had to keep undoing the battery box.

Now the screen has gone blank, buzzer keeps sounding and HUD flashing!

To top it all off, all I can hear at the moment is a constant beeping in my ear, even though the unit is off!

Anyone suffered the same problem?

Batteries used are the panasonic ones, have been using them fine since I got the unit and have a 2010 best before date on them

Hope the meg fares better!

I am currently dealing with the exact same problem! I hope to hear from AP on Monday

Could you let me know how you get on please?

this could be your problem, a bought 4 pennasonic before i got my unit, but after reading on here the problems that some people have had with them i gave them away and got Fujitsu Lithium ,these are the ones that APD say to use.
try using them to see if that works, before you get intouch with APD
as they may just say change batteries from panasonic to fujitsu
safe diving

Thats fair enough, but I have been using these batteries since I got the unit last year(obviously not the same ones!)

How can it now suddenly decide it doesnt like a battery after 8/9 months?

here is my conclusion on battery brand from an earlier post:
"what batteries are you using? I'm wondering if that may make a difference. I'm starting to think these issues are more voltage issues than software issues. I was testing some batteries the other day by briefly putting them in B1 and starting up the unit. turns out i had gotten a few nearly dead ones mixed in and after turning the controller on and off with each battery i tried, a missed deco alarm came on (the dead batteries it turns out were past there expiration date).

It seems that the system is very sensitive to drops in voltage or low voltage, the timers in particular. I've seen a drop in voltage and subsequant hand off to B2 in another unit trip the cns alarm on a unit my wife was barrowing. the battery got low toward the end of the dive and on the way up the increased and prolonged draw of the solenoid working to sustain the po2 drew down the battery before the system had a chance to swap to B2...or so it seems in retrospect.

I think there is something to using the fijitsu battery and now it seems the duracell ultra will do the job too. both seem to be able to sustain adequate voltage with the ups and downs of the solenoid to prevent the controllers from being robbed so much juice that the clock gets thrown off... and there is more than one clock, one may get effected and the other may not...or so it seems.

i do not have the latest software in my unit, my wife's does have the latest. Since religiously holding down the power button for three seconds and using duracell ultra batteries neither of us have had issues with either the latest software or the previous version. I'm seriously thinking this is at the very least not always a software issue, or possibly not a software issue int he first place...that would explain why new version continue to have the same old problems...are you listening AP?

i've concluded that it's best not to push the batteries, even the right brand batteries. I'm keeping an eye on the batteries on the ascent at the end of each dive and making a note of how charged they are then...after 17 hours of actual dive time, i'm tending to chuck them... or give them to a friend to use up in their camera. None of this is fact, just passing on some observations and possible explanations.

hope that helps"

I am still puzzled by the fact that somehow you see people thinking that the best way to solve a problem is to first ask all the so-called "experts" on public forums. Sure, asking if you've seen it before is one but stating the message already in a way I (as non-english speaking nitwit) can only understand it as a last resort because your manufacturor isn't going to help you is insane.

If I have problems like that with my unit my first port of call will be my own knowledge of the unit and if that fails it'll be APD (in my case). Again, I'm still surprised to see messages which give the impression that manufacturors are not to be trusted before even contacting them while any cyberdiver can be trusted with your life.

Just my 2cents

I'll agree with that.


For what its worth I have an inspiration vision and also an evolution, I have had no problems at all with the electronics or anthing else for that matter and if I had i would speak with APD in the first instance.

Well,thanks for the above comments but it was to see if anyone had had the same problem as me..also APD arent open on sundays!!

Dave, the owner of LDS and very good on his rebeathers, just told me its a software glitch..he s had it on his..and also how to sort it

There are people that know alot more than me about rebreathers and i thought the aim of a forum was public discussion and to share knowledge/ experiences?

Just my 50 pence worth.

RichardGreen

Fine, I thought I'd share mine.
