Suunto mosquito logbook showing -17

[Faithoj]

Hi
Borrowed my friend's Mosquito and when scrolling to the first logbook page, the top of the display shows -17. Does anyone know what this means, I've had a look in the manual and don't seem to find anything obvious.

Thx

At this point I'm already in the logbook page 1, as I can see the start time of dive, dive number of the series, date. '-17' is directly under the Suunto symbol
Thx

I've got the manual p79 shows the page I'm on in the logbook, their diagram shows -0.0, but doesn't explain the number. Sorry if I'm missing something obvious :-s
