Dive Planning [Plan] - Suunto Vyper User Manual

3.1.3. Dive Planning [PLAN]

It is possible at any time in the Surface Mode to enter the Planning Mode, simply
by pressing the PLAN button. After showing the text PLAN (Fig. 3.6), the display
will show the no-decompression limit for the depth of 9 m [30 ft]. By pressing
the arrow down TIME (t) button, the dive computer will calculate and show
the next deeper no-decompression limits in 3 m [10 ft] increments ending at 45
m [150 ft]. By pressing the arrow up PLAN (s) button the next shallower depth
will be shown again.
The Planning Mode can be canceled by pressing the SMART (QUIT) button.
NOTE! The Planning Mode is disabled in GAUGE mode and in the Error
Mode (see section 3.8. "Error Conditions").
Higher Altitude or Personal Adjustment Modes will shorten the no-decompression
time limits. These limits at different Altitude and Personal Adjustment
Mode selections are shown in Table 6.1 and 6.2 in Section 6.1. "Operating
Principles".
Planning Mode also accounts for the following information from previous
dives:
• calculated residual nitrogen or
• surface intervals up to four days between the dives.
The no-decompression times given for different depths will therefore be shorter
than before your fi rst "fresh" dive.
DIVE NUMBERING SHOWN DURING DIVE PLANNING
Repetitive dives belong to the same repetitive dive series if the instrument still
has been counting no-fl ying time.
When the surface time is less than 5 minutes, the dives are considered to be one
and the same. The dive number will not change for the second part of such a dive
and the dive time will continue where it left off (see also section 3.5.2. "Dive
Numbering").
