Suunto D5
Customization is divided into four categories:
Dive mode name
Dive algorithm
Gas settings
Customize views
Dive mode (name)
Maximum length of the name is 15 characters. Use something short and simple that helps you
identify easily the features and information that you have customized on this mode.
Dive algorithm
You can select to use Suunto Fused™ RGBM or no algorithm (see 3.27. Suunto Fused RGBM). If
you select no algorithm, Suunto D5 functions as a gauge (bottom timer) in that mode. If you
select Suunto Fused RGBM, you have two additional options: personal setting (algorithm
conservatism) and altitude setting.
Gas settings
Here you configure what you see under the Gas(es) menu in Suunto D5. The multiple gases
option can be turned on or off. Turn it on to be able to dive with multiple gases. When turned
off, the gas menu is simplified and easier to use with only one gas.
The gas max pO
setting can be set to manual or fixed. The fixed option means that the
2
selected value is used for all gases and the option to manually edit them in the Gas(es) menu
is disabled. When manual is selected, you can edit the gas max pO
in the Gas(es) menu.

3.9. Decompression Dives

If you exceed the no-decompression limit on a dive, Suunto D5 provides the decompression
information required for ascent. Ascent information is always presented with two values:
ceiling: depth that you should not go above
asc. time: optimum ascent time in minutes to surface with given gases
WARNING: NEVER ASCEND ABOVE THE CEILING! You must not ascend above the
ceiling during your decompression. In order to avoid doing so by accident, you should stay
somewhat below the ceiling.
On a decompression dive, there could be three kinds of stops:
Safety stop
Deep stop
Decompression stop
You can turn deep stops on or off under DIVE SETTINGS / PARAMETERS. In addition, you
can adjust the safety stop time to be 3, 4 or 5 minutes.
The illustration below presents how decompression is displayed on Suunto D5. When you
ascend close to the ceiling depth and enter the deco window area, two arrows appear in front
of the ceiling number.
