SUUNTO D9tx - Manual (Page 74)

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 shortens 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.
5.11. Deep stops
The Suunto Technical 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.
DURING DESCENT,
YOU'RE SHOWN THAT A
DEEPSTOP IS NEEDED AT
THE DEPTH OF 16 M.
DURING ASCENT, YOU'RE
ADVICED TO MAKE A DEEP
STOP AT 16 M FOR THE
DURATION SHOW BY THE
TIMER (42 S REMAINING).
Enabling the deep stops does not disable Recommended Safety Stops. Mandatory
Safety Stops, for example due to continuous ascent rate violations, are still prompted.
