Mike--Yes, this is helping very much. I'm posting here, rather than private e-mail, because there seem to be several folks here missing manuals to these or similar computers.
OK, on my Sherwood Sigma II, the start-up sequence looks very similar, but slightly different. To be precise, here are the steps (my comments/questions in parentheses):
1. All the large digits are "drawn" quickly, one by one.
2. The Ceiling Alarm LED flashes, and the Ascend Slower LED is on. All the digits appear as 188, with all the other displays also showing:
CEILING
TO FLY
NEXT DIVE
LOG
SURFACE
LOG
(I assume this is just to show that all the digit segments, LEDs, and displays are working.)
3. The LEDs are flashing/on as in step 2., with the following digits displayed:
11 11 1
10
11 11 1
(What is this?)
4. No LEDs from now on, and the digits display:
Lo
Lo
Lo
(Checks the low voltage notification?)
5.
EE
EE
EE
(What?)
6. The following shows up in the Depth display:
or (I assume this checks the Out Of Range display, like if the computer goes too deep?)
7. Next, the following show up in the Depth and Elapsed Time displays:
go
up
(I assume this checks the functioning of the display telling you to move to more-shallow water?)
7. Finally, the three digital displays show the following simultaneously:
115 (battery voltage? ... pretty good after 14 years, eh?)
11 11 1 (what??)
33 (the surface altitude calibration? ... we're about 50m above sea level here)
Then it goes into the dive planning sequences... depth/max time/surface. (what does "surface" tell me?)
Grrr... Drives me crazy to have a piece of gear that's supposed to help keep me safe, and I don't have a manual for it. Yes, I will use also dive tables as a reality check.
Anyway, you're being a tremendous help. Thanks again/still.
By the way, any problems over the years wht the SD's notorious (?) battery compartment flooding problem? My Sigma has a knurled aluminum threaded plug with o-ring... just needs normal o-ring care? Is the battery compartment sealed off from the electronics?

miked:Hi Marek K,
I have had a Skinny Dipper II for many years, and it shows battery level during startup as follows:
after a number of displays, we get, (in sequence);
the 3 vertical levels of display are as in the SDII:
First, Then then then then
"LO" "EE" ###**
"LO" "EE" "or"* "go" /////
"LO" "EE" "up" 32
* "or" means "out of range"
**this is the ### that shows battery voltage:
According to the manual,signifying:
75-120: Normal operation
63-74: normal operation, with a flashing "lo" during use.
46-62 No LEDS ,and 2 "Lo" flashes
30-45: 3 "lo",and no new start up.
0-29 shut down
Personally, i'd replace batteries if this number gets below 63.
BTW, the "32" in the final display is a pressure calibration32,33,or 34 are ok for sea level.
Hope this helps,
Mike
