Oceanic Versa Pro says "ALT".

[Chuck Tribolet]

I dove yesterday. This morning, when I fired up my Versa Pro, it thought I was in
the water and VERY nitrogen saturated, and had a 10' ceiling. Something was crazy,
so I pulled the battery and put it back in. Now, when powered on, it does the count
down and just says ALT flashing for a few seconds, then shuts down. I tried a fresh
battery, same thing. I'm guessing it's sick.

Nobody knows what "ALT" means?

Could mean "alternate".
Could mean "altitude".
Could mean ...

I checked the online manual and my Pro Plus 2 manual, I can't find an ALT.

I've got an ALM and an ACT, but no ALT.

Did you get on an airplane, or otherwise have any major change of altitude while the unit was still in the 24 hour time to fly mode??

Probably "altitude error".

My guess is that your pressure sensor is hosed and giving incorrect readings. When you put in a new battery and the unit checked the pressure sensor to guesstimate your altitude, it came up outside the allowable limits.

Chuck,

Pull the battery and let it power down for 24 hours and then put the new battery back in.

Yep. My Versa did that. Oceanic replaced it.

Charlie99 got it. ALT is displayed following diagnostic check, when the sensor calibration is not within spec. Feel free to remove and replace the battery, it's not going to cause any additional problems - chances are it is going to need to be serviced.

Just to give some belated feed back, pulling the battery for 24 hours didn't help. I had the unit
serviced (for a lot less than the cost of a new computer, even with Oceanic's Trade-Up policy).

Thanx all.
