Alt 2 - Aqua Lung i750TC Owner's Manual

ALT 2

The ALT 2 screen displays time of day, temperature, date, and current elevation readings.
ALT 3
The ALT 3 screen displays the FLY (Time to Fly) and the DESAT (Desaturation) countdown. The Time to Fly
countdown shall begin counting from 23:50 to 0:00 (hr:min), 10 minutes after surfacing from a dive. The DESAT
counter shall provide calculated time for Tissue Desaturation at sea level taking into consideration the CF (Con-
servative Factor) if the i750TC CF setting was set on. It shall begin counting down 10 minutes after surfacing from
DIVE or FREE dives counting down from a maximum of 23:50 to 0:00 (hr:min). When the DESAT countdown
reaches 0:00 (hr:min), which will generally occur prior to the FLY countdown reaching 0:00 (hr:min), it will remain
on the display as 0:00 until the Fly countdown also reaches 0:00.
NOTE: Desaturation requiring times greater than 24 hours will display the graphic > 24:00. In the event
that Time to Desaturate still remains at the end of 24 hours, the unit will turn Off and any Nitrogen and
Oxygen calculations will clear.
ALT 4
The ALT 4 screen displays only after a nitrox dive. It displays the current oxygen saturation level and the current
gas mix.
