Can anyone advice or help... Dive computer problem

[HfR]

I have a Mares puck dive computer. I have been diving for a few months, several dives a day, no problem. I have somehow managed to change the settings, so that it will now only allow one dive in 24 hours. On the second descent the computer will not activate, it simply tells me time till I can fly. This has happens twice and I have had to abort my second dive. I am travelling alone around the world, and I have lost my manual for the computer and have limited internet access. Can anyone advice me on how to contatc mares, or how to change the settings. I feel stupid but I cannot work out what I have changed. At present therefore I can only dive once in 24 hours with my computer? Can anyone help?

Question 1: Try a new battery. Had an Aeris that would not hold the Nitrox setting. New battery cured that. Battery was used up after only a few months.

Question 2: What does dive 1 look like? There are computers that will lock you out if you violate certain things on dive one.

I have just been doing dives around 6-8 metres as part of a coral survey team, with very conservative dive parameters. so no chance I violated anything, it's also happened twice, so that's probably not it, I can try a new battery though, thanks.

The Mares has a default setting that will lock you out after an unsafe ascent.

There are two things you need to do:

1.) In "Set Alarm" mode set FastAsc to OFF
2.) Stop making unsafe ascents

If you only diving to those depths why not just use Tables?

Like you said you don't have much of internet access, but will it help that I send you a .pdf file of the manual to your e-mail address that are theoretically not so heavy to down load, whenever you get access to internet ???

I will be back in 6 hours, I will go diving today so you will need to wait some time.

I have a size reduced version of the Puck manual.

Ran it thru Acrobat 8 and reduced it down to 1MB.

It's on my Google Drive which is public if you have the link.

I just PM'd it to you.

Hi, thank you for the advice. I will try this, though in all honesty I do not think that could be the problem, as I am shore diving, so it's a slow swim in ascent to shore and I had dived like that 30+ times with several instructors and it worked fine. I think I changed a setting without realising. But I will now go and look at what you have suggested and check it and I really appreciate the advice. Thanks.

Checking the BSAC 88 Tables you could do 167 minutes at 9m for dive 1 then another 116 minutes on dive 2 if you had a 2 hour surface interval.

I'm not intimately familiar with the MARES, but for many computers a "fast ascent rate" doesn't necessarily mean "to the surface" but merely at any portion of the dive. If you went too quickly from 10m to 5m and then did a slow shore swim in... that might qualify as a "fast ascent."

My Suunto will give me an ascent rate warning if I raise my hand quickly... so that's no more than a 2m swing in depth.
