5.10. Activation and pre-checks
This section describes how to activate the DIVE mode and explains the pre-checks that
it is highly recommended you perform before you get into the water.
5.10.1. Accessing DIVE mode
The Suunto HelO
2
has two diving modes: MIXED GAS mode for diving with gas mixes
and GAUGE mode for use as a bottom timer.
The chosen dive mode is displayed when the DIVE mode is accessed, and you can toggle
between the submodes by pressing the UP/DOWN buttons.
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 etc.
After activation, all graphical display elements are turned on, and the backlight and the
beep are activated. A few seconds later the battery power indicator is shown.
At this time, perform your pre-checks, making sure that:
•
the instrument operates in the correct mode and provides a complete display (MIXED
GAS/GAUGE mode)
• the battery level is ok
