After activation of the Dive Mode or after diving, the Mosquito will automatically
switch to show the time keeping display within 5 minutes to conserve the battery
power, if you do not press any buttons. However, the dive computer functions will
remain active until it has calculated that all residual nitrogen has off-gassed. This
may take up to 100 hours, as described in chapter 7.1. ”Operating Principles”.
However, SUUNTO recommends to turn on the Dive Mode before diving to check
the settings, battery warning, etc. and for dive planning.
