2. W ARNINGS, CAUTIONS, AND NOTES Throughout this manual, important safety icons are displayed. Three classifications are used to separate these icons by their order of importance: W ARNING is used in.
W ARNING DIVES THA T REQUIRE DECOMPRESSION STOPS ARE NOT RE- COMMENDED. YOU SHOULD ASCEND AND BEGIN DECOMPRES- SION IMMEDIA TEL Y WHEN THE DIVE COMPUTER SHOWS YOU THA T A DECOMPRESSION STOP IS REQUIRED! Note the blinking ASC TIME symbol and the upward pointing arrow .
W ARNING SELECT THE CORRECT AL TITUDE ADJUSTMENT SETTING! When diving at altitudes greater than 300 m/1,000 ft the Altitude Adjustment feature must be correctly selected in order for the computer to calcu- late the decompression status. The dive computer is not intended for use at altitudes greater than 3,000 m/10,000 ft.

4. GETTING ST ARTED WITH YOUR SUUNTO HELO2 T o get the most out of your Suunto HelO 2 , take some time to personalize it and really make it YOUR computer . Set the correct time and date, tones, unit and backlight settings. Suunto HelO 2 is a very user-friendly dive computer , and you will quickly become familiar with its functions.
ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. 4.1.4. Setting the backlight Use the BACKLIGHT SETTING mode to turn the backlight on or off and to define how long it stays on for (5, 10, 20, 30, or 60 seconds). When the backlight is turned off, it does not illuminate when an alarm sounds.
5. BEFORE DIVING Do not attempt to use the dive computer without reading this user's manual in its entirety , including all the warnings. Make sure that you fully understand the use, displays, and limitations of the instrument.
YOU ARE ADVISED TO MAKE A DEEPSTOP A T 18 M. THE SECOND INDICA TOR SHOWS THA T YOU HA VE 1 10 SECONDS LEFT OF YOUR DEEPST OP . In order to optimize the response to different increased risk situations, an additional category of stop, referred to as a Mandatory Safety Stop, has been introduced.
5.6. Audible and visual alarms The dive computer has audible and visual alarms that advise when important limits are approached or that prompt you to acknowledge preset alarms. The table below describes the different alarms and their meanings. T able 5.
Alarm reason Alarm indication The selected depth (3 - 120 m / 10 - 394 ft) is exceeded. Three beeps with a one second interval for 24 seconds. Maximum depth blinks. The fixed maximum depth (120 m / 394 ft) is exceeded. The selected dive time (1 - 999 min) is ex- ceeded.
Omitted decompression The Error mode results from omitted decompression, i.e. when you stay above the ceiling for more than three minutes. During this three-minute period the Er warning is shown and the audible alarm beeps. After this, the dive computer will enter a permanent Error mode.
2. Ensure that the Suunto HelO 2 is turned on, and that the wireless integration is enabled in the Suunto HelO 2 settings (HP set ON, see Section 5.9.8. Setting the HP code ). The HelO 2 should display “cd:--” in the lower left corner of the alternative display .
A B C D E 5.9. MIXED GAS DIVE mode settings Suunto HelO 2 has several user-definable functions, as well as depth and time-related alarms that you can set according to your personal preferences.
The ASC time is calculated based on the assumption that you start the ascent profile im- mediately and all the PRIMARY gases are changed as soon as their maximum operating depth allows it. That is, using the gases that are set as primary , the most optimal ascent schedule for the moment is calculated.
ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. 5.9.5. Setting the sample rate The sample rate controls how often the depth, time, tank pressure, and water temperature is stored in the memory . Y ou can set the dive profile sample rate to 10, 20, 30, or 60 seconds.
ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON. SELECT T ANK PRESSURE ON. 5.9.9. Setting the units Use Unit Settings to choose between metric (meters/celsius/bar) and imperial (feet/fahrenheit/psi) units. ADJUST WITH UP AND DOWN BUTTONS. ACCEPT WITH SELECT BUTTON.

WHEN CEILING AND STOP ARE DISPLA YED, MAKE A ONE MINUTE MANDA TORY SAFETY STOP IN THE DEPTH ZONE BETWEEN 6 M AND 3 M. Y ou must not ascend shallower than 3 m/10 ft with the Mandatory Safety Stop warning on. If you ascend above the Mandatory Safety Stop ceiling, a downward pointing arrow will appear and a continuous beeping starts.
6. DIVING This section contains instructions on how to operate the dive computer and interpret its displays. Y ou’ll find that this dive computer is easy to use and read.
6.1.2. Bookmark It is possible to record bookmarks in the profile memory during a dive. These bookmarks are displayed when scrolling the profile memory on the display . The bookmarks will also be shown as annotations in the downloadable Suunto Dive Manager PC software.
The ascent time (ASC TIME) is the minimum amount of time needed to reach the surface in a decompression dive. It includes: • the time needed at the deep stop • the time needed to ascend to the ceiling at an ascent rate of 10 m/33 ft per minute.
W ARNING NEVER ASCEND ABOVE THE CEILING! Y ou must not ascend above the ceiling during your decompression. In order to avoid doing so by accident, you should stay somewhat below the ceiling. Display below the floor The blinking ASC TIME and an upward pointing arrow indicate that you are below the floor .
DECOMPRESSION DIVE, ABOVE CEILING. NOTE DOWNW ARD POINTING ARROW , ER W ARNING AND ALARM. Y OU SHOULD IMMEDIA TL Y (WITHIN 3 MINUTES) DESCEND T O OR BEL OW CEILING. In addition, an Error warning (Er) reminds you that you have only three minutes to correct the situation.

7. AFTER DIVING Once back at the surface, Suunto HelO 2 continues to provide post-dive safety information and alarms. Calculations to enable repetitive dive planning also help to maximize diver safety .
7.3. Repetitive dive planning The Suunto HelO 2 includes a dive planner that allows you to review the no-decompression limits on a subsequent dive, taking the residual nitrogen loading of previous dives into consideration. The dive plan mode is not meant for technical dive planning which the Suunto Dive Planner PC software is meant for .
By pressing the UP/DOWN buttons, you can scroll the no-decompression limits in 3 m/10 ft increments ending at 45 m/150 ft. No-decompression limits longer than 99min are dis- played as “—“. WHEN ENTERING THE PLANNODEC MODE THE DISPLA Y FIRST BRIEFL Y SHOWS THE REMAINING DESA TURA TION TIME BEFORE GOING INTO PLAN MODE.
The dive time and date are registered in the Logbook memory . Always check before diving that the time and date are correctly set, especially after traveling between different time zones. 7.6.1. Dive logbook (MEMLogbook) The Suunto HelO 2 has a very sophisticated, high capacity Logbook and Profile Memory .
• OLF percentage of MIXED GAS dive Page III • scrolling • dive profile (temperature, depth, tank pressure, gases) NOTE The memory will retain approximately the last 42 hours of dive time. After that, when new dives are added, the oldest dives are deleted.
NOTE For emergency ascents, always print out the dive plan from Suunto Dive Planner . It ensures that you have a valid decompression schedule at hand in an unlikely event that the dive computer malfunc- tions.
