An interruption of the Link may also occur while the Display
Module is in an area within 3 to 4 feet (1 meter) of a running
Dive Propulsion Vehicle. The Link will be restored within 4
seconds after the Vehicle is shut off or the Display Module is
moved out of that area. When using a Strobe, a temporary
interruption may occur shortly after the Strobe flashes. The Link
will be restored within 4 seconds.
PRE DIVE PLANNING SEQUENCE
Oceanic strongly recommends that you review the
Pre Dive Planning Sequence (PDPS) prior to every
dive to help you plan your dive as required to avoid
exceeding no decompression or oxygen exposure
limits.
This is especially important for repetitive dives when the
PDPS indicates adjusted dive times that are available for the next
dive, based on residual nitrogen or oxygen accumulation (which-
ever is in control) following the last dive and surface interval.
The PDPS provides a sequence of theoretical dive times available
for depths ranging from 30 feet (9 meters) to 190 feet (57 meters)
in 10 foot (3 meter) increments. During the sequence, no decom-
pression times are only displayed for depths where there is at
least 1 minute of theoretical dive time available at the depth,
taking into account descent and ascent rates of 60 feet (18
meters) per minute.
