500AI

Plan Mode Prior to a 'Repetitive Nitrox Dive'

If the segments of the Nitrogen Bar Graph are displayed (Fig 37) during the

Planning Sequence, that next dive is calculated to be controlled by nitrogen

If the segments of the O2 bar graph are displayed (Fig. 38), that next dive is

calculated to be controlled by oxygen loading.

The 500AI will store oxygen accumulation for up to 10 dives conducted during

a 24 hour period. In the event that the maximum limit for oxygen loading has

been exceeded for that day, all of the segments of the O2 bar graph will be dis-

played (Fig. 39).

Depth and Time displays will not appear until the O2 bar graph recedes into

the green (normal) zone (e.g., your daily oxygen dosage decreases an amount

equivalent to the amount accumulated during the latest dive completed).

WARNING: The 500AI must be manually activated and be in an

operating mode prior to start of a dive. The unit will not acti-

vate automatically by immersion in water. Also, FO2 must be

verified or set prior to commencing each nitrox dive.
