6.1.2. Bookmark

It is possible to record bookmarks in the profile memory during a dive. These bookmarks
are displayed when scrolling the profile memory on the display. The bookmarks will also
be shown as annotations in the downloadable Suunto Dive Manager PC software.
The bookmark logs the depth, time, water temperature, and tank pressure when available.
To make a bookmark in the profile memory during a dive, press the SELECT button. A
brief confirmation will be given.

6.1.3. Ascent rate indicator

The ascent rate is shown graphically along the right hand side. When the maximum allowed
ascent rate is exceeded, the lower segments start to blink with the top segment staying
solid, indicating that the maximum ascent rate has been exceeded continuously or that
the current ascent rate is significantly above the allowed rate.
WARNING

6.1.4. Safety Stops

A 3 minute Recommended Safety Stop is prompted after every dive to over 10m.

6.1.5. Decompression dives

When your NO DEC TIME becomes zero, your dive becomes a decompression dive so
you must perform one or more decompression stops on your way to the surface. The NO
DEC TIME on your display will be replaced by an ASC TIME, and a CEILING notation will
appear. An upward pointing arrow will also prompt you to start your ascent.
If you exceed the no-decompression limits on a dive, the dive computer will provide the
decompression information required for ascent. After this, the instrument will continue to
provide subsequent interval and repetitive dive information.
Rather than requiring you to make stops at fixed depths, the dive computer lets you de-
compress within a range of depths (continuous decompression).

NORMAL
ASCENT
RATE.
DO NOT EXCEED THE MAXIMUM ASCENT RATE! Rapid ascents
increase the risk of injury. You should always make the Mandatory
and Recommended Safety Stops after you have exceeded the max-
imum recommended ascent rate. If this Mandatory Safety Stop is not
completed, the decompression model will penalize your next dive(s).
Continuous ascent rate violations will result in Mandatory Safety Stops.
When Recommended Deep Stop is enabled, the length is indicated
in seconds.
