Owner's Manual

WHEN CEILING AND STOP ARE DISPLAYED
WITH DOWNWARD POINTING ARROW,
IMMEDIATELY (WITHIN 3 MINUTES) DESCEND
TO OR BELOW CEILING.
If you continue to violate the Mandatory Safety Stop, the tissue calculation model is
affected and the dive computer may shorten the available no-decompression time for
your next dive. In this situation, it is recommended that you prolong your surface interval
time before your next dive.
5.12. Deep stops
In Suunto DX deep stops are activated on all dives below 20 m / 66 ft.
The Suunto Fused RGBM model calculates deep stops iteratively, placing the first
stop about halfway between the maximum depth and the ceiling depth. After the first
deep stop is completed, another deep stop will be prompted halfway to the ceiling,
and so on until the ceiling depth is reached. However, deep stops are deactivated
when the decompression ceiling descends to ¼th depth (or deeper) of maximum depth
of the dive.
Enabling the deep stops does not disable Recommended Safety Stops. Mandatory
Safety Stops, for example due to continuous ascent rate violations, are still prompted.
If a deep stop is violated, it does not cause the dive computer to go into an error (Er)
mode. However, a penalty time may be added to the subsequent decompression.
