NOTE
The memory will retain approximately the last 42 hours of dive time.
After that, when new dives are added, the oldest dives are deleted.
The contents of the memory will remain when the battery is changed
(providing that the battery has beenreplaced according to theinstruc-
tions).
NOTE
Several repetitive divesare consideredto belongto thesame repetitive
dive series if the no-fly time has not ended. See Section 7.2. Dive
numbering for further information.

The dive history is a summary of all the dives recorded by the dive computer.

7.7. Suunto Dive Planner (SDP)
Suunto Dive Planner is an essential part of your dive. It is used for creating dive plans.
WARNING
Using the Suunto Dive Planner software is not a substitute for proper
dive training. Diving with mixed gases has dangers that are not famil-
iar to divers diving with air. To dive with trimix, triox, heliox and nitrox
or all of them, divers must have specialized training for the type of
diving they are doing.
Start creating a dive plan by defining the maximum depth and bottom time. Next, plan
travel, bottom and decompressiongases. Based on the gases, the DivePlanner calculates
the decompression schedule, gas change and decompression depths. After the decom-
pression schedule is ready, the needed gas volume for the dive is calculated based on
the Surface Air Consumption (SAC) rate that can be checked from Suunto Dive Manager.
WARNING
Always use realisticSAC rates andconservative turn pressures during
dive planning. An over-optimistic orerroneous gas planning can result
in the exhaustion of breathing gas during decompression or in a cave
or a wreck.
After youfinish planning your divewith Suunto Dive Planner, download thegases, settings
and alarms into your dive computer. You can use your Suunto HelO
2
to fine-tune the set-
tings and gases manually.
Always use alternative dive planning methods, such as dive tables, when you plan the
dive. After planning your dive, analyze your dive gases and if they differ substantially from
the planned gases, replan your dive. Also check the lost gas scenarios in case your de-
compression gases are alteredduring a dive, for example, due toa lost cylinder or a broken
valve.
