Dive Mode Activation - Suunto D4i User Manual

5.10.2. DIVE mode activation

The dive computer activates automatically when submerged deeper than 0.5 m/1.5
ft. However, it is necessary to activate the DIVE mode BEFORE diving to check
the altitude and personal adjustment settings, battery condition, oxygen settings
, and so on.
After activation, all graphical display elements are turned ON, and the backlight and
the beep are activated. After this, the selected altitude and personal settings are dis-
played. A few seconds later the battery power indicator is shown, as well as the
maximum operating depth (MOD, 66.2 m), O2% (21%) and PO2 (1.6) value. A few
seconds later the battery power indicator is shown.
WARNING
At this time, perform your pre-checks, and ensure that:
• the instrument operates in the correct mode and provides a complete display
(AIR/NITROX/FREE mode)

SUUNTO STRONGLY RECOMMENDS THAT SPORT DIVERS

greater depths increases the risk of oxygen toxicity and decom-
pression sickness.
