Operation Manual

If you descend below the required decompression ceiling before 5

minutes have elapsed, the unit will continue to function in Decom-

pression Dive Mode. In this case, no off-gassing credit will be

given, and for each minute you were above the ceiling 1

minutes

of Penalty Time will be added to Required Stop Time.

The added Penalty (decompression) Time will then have to be

worked off first, before obtaining off-gassing Credit.

Once the Penalty Time is worked-off, and off-gassing Credit be-

gins, required decompression Stop Depths and Time will decrease

toward zero, then the Nitrogen Bar Graph will recede into the yel-

low Caution Zone and operation will revert to the No Decompres-

sion Dive Mode.

Delayed Violation 1

If you remain above the Required Ceiling Stop Depth for 'more

than 5 minutes', the full Nitrogen Bar Graph and Total Ascent

Time display will flash (Fig. 33) until you descend below the Re-

quired Stop Depth. This is a continuation of Conditional Violation.

Delayed Violation 2

The XR1 cannot calculate decompression times for Stop Depths

much greater than 60 FT (18 M) and offers no indication of how

much time spent underwater would result in the need for a greater

Stop Depth.
