500AI

If the Time to Desaturate is calculated to be greater than 9:59, the display will

indicate 9:- - (Fig. 54) until it decreases to 9:59.

If a violation occurred during the dive, Time to Desaturate will not be dis-

played and a single dash ( - ) will appear instead of the letters FLY (Fig. 55a).

To access Plan Mode:

• press the Advance (Left) button 4 times (while in Surface Mode)

• press the Select (Right) button to scroll through the sequence

• The unit reverts to Surface Mode after 2 minutes, unless the Advance

(Left) button is pressed to access the Log Mode.

The Planning Sequence will now show 'adjusted' No Decompression Limits

(Fig. 56) based on residual nitrogen calculated to be remaining from the previ-

ous dives. Calculated dive times and the maximum allowed depth displayed

will increase as the real time surface interval increases after completion of a

dive.

The Planning Sequence will only scroll to the maximum depth allowed by the

nitrogen or oxygen limit, whichever is in control. The respective bar graph

will be displayed to indicate which is in control.
