3.1 Activation and pre-checks
Unless the dive mode turned off, the dive mode activates
automatically when you dive deeper than 1.2 m (4 ft). However, you
should switch to dive mode before diving to check battery
condition, the display and so on.
Each time your Suunto D4f enters dive mode, a series of automatic
checks are performed. All graphical display elements are turned ON,
and the backlight and the beep are activated. Then the battery level
is checked.
