6.4.2. Free dive time limit
The FREE mode has a time limit of 10 minutes. After 10 minutes, Suunto D9tx will
automatically change from Free Dive to Scuba Bottom Timer (GAUGE). After the dive,
the no-fly time will countdown from 48 hours. Also, you will not be able to dive in AIR
or MIXED modes until the no-fly time has counted down to zero. You can only set the
DIVE mode to GAUGE or OFF.
NOTE
If you want to dive in AIR or MIXED mode after diving in FREE
mode, remember to switch to the correct mode. Otherwise,
the free dive time limit will activate after 10 minutes.
