DIVE SURFACE MODE
© Aqua Lung International, Inc. (2018)
PLAN
Pressing the SEL button while viewing the PLAN Lead-in screen accesses the dive planner mode. This mode
calculates dive depth and time limits. To do so, it accounts for any residual nitrogen, oxygen, surface intervals,
the programmed gas mix, and PO
2
alarm setting. Either NO DECO (Decompression) MIN or O
2
MIN limits are
displayed, depending on whether nitrogen or oxygen levels will be the limiting factor. The time limit will display as
1-99 minutes, all times greater than 99 display as 99.
NOTE: Depths exceeding the MOD (Maximum Operating Depth), if nitrox, or that have less than 1 min-
ute allowed dive time will not be displayed.

LOG
Pressing the SEL button while viewing the LOG Lead-in screen accesses the dive log. The log stores Information
from the latest 24 DIVE and/or GAUGE mode dives for viewing.
> If no dives are recorded, the message NONE YET 0 DIVE will be displayed in the log.
> After exceeding 24 dives, the most recent dive is stored while the oldest is deleted.
> Dives are numbered from 1 to 24 starting each time a dive is activated in either Dive (or Gauge) mode. After
the post dive 24 hour period has elapsed and the unit shuts off, the first dive of the next activation period will be
recorded as dive #1.
> I n the event that dive time (min) exceeds 999 min, the data at the 999 interval is recorded in the Log upon sur-
facing of the unit.
NOTE: New data will automatically overwrite the oldest data in memory when the memory becomes
full. The i550C Log and Di Download data is stored separately in different partitions of the
memory. The Log only stores a short summary of each dive. Alternately, the Di Download
function stores much larger files for each dive. For this reason, it is normal to see dives stored in the
i550C's onboard Log that have already been overwritten in the Di Download Partition. If you do
not remember to log or download your dives, they will be lost when the memory overwrites. See the
Di Download section of this manual for instructions on downloading dives.
