INTRODUCTION Congratulations on your choice of the SUUNTO Dive Computer. It is a compact and sophisticated dive instrument that will give you years of trouble free and joyful diving. The dive computer will provide you with important information that you will need during, between, and after your dives. KEY FEATURES The dive computer monitors and reports vital information such as your dive time, current depth, maximum depth, no-decompression time and ascent rate.
METRIC AND IMPERIAL UNITS All examples in this manual are shown in metric units, including meters and °C. The corresponding imperial units are shown in brackets. The instrument is also available with imperial units, i.e. feet and °F. WARNING! VERIFY THAT THE UNITS OF MEASURE, WHETHER METRIC OR IMPERIAL, ARE CORRECT BEFORE STARTING TO DIVE! Any confusion resulting from improper selection of units may cause the diver to commit errors that may lead to serious injury.
1. FOR YOUR SAFETY Always remember that THE DIVER IS RESPONSIBLE FOR HIS OR HER OWN SAFETY! When used properly this dive computer is an outstanding tool for assisting properly trained, certified divers in planning and executing standard and multi-level sport dives within the described no-decompression limits. It is NOT A SUBSTITUTE FOR CERTIFIED SCUBA INSTRUCTION including training in the principles of decompression. DO NOT attempt to use this dive computer without reading this entire Instruction Manual.
SHARING THE DIVE COMPUTER WARNING! THE DIVE COMPUTER SHOULD NEVER BE TRADED OR SHARED BETWEEN USERS WHILE IT IS IN OPERATION! Its information will not apply to someone who has not been wearing it throughout a dive or sequence of repetitive dives. Its dive profiles must match that of the user. If it is left on the surface during any dive, it will give inaccurate information for subsequent dives. No dive computer can take into account dives made without the computer.
PERSONAL/HIGH ALTITUDE ADJUSTMENT More information about this is given in Section 3.6, “Personal Adjustment and High Altitude Dives”. WARNING! SET THE CORRECT PERSONAL/ALTITUDE ADJUSTMENT MODE! When diving at altitudes greater than 700 m [2300 ft] the personal/altitude adjustment feature must be correctly selected in order for the computer to calculate no-decompression status.
DECOMPRESSION DIVES WARNING! DO NOT USE THIS INSTRUMENT TO CONDUCT DECOMPRESSION DIVES! Suunto does not recommend this instrument to be used to conduct decompression dives. However, if through carelessness or emergency a diver is forced to exceed the no-decompression limits on a dive, the instrument will provide decompression information required for ascent. After this the dive computer will continue to provide subsequent interval and repetitive dive information.
HIGHER RISK DIVE PROFILES The user must understand that all decompression devices (decompression tables and/or dive computers) are based on mathematical models and that many experts are currently concer ned that these models may not under certain conditions adequately describe the physiological phenomena. These conditions are presently identified as dives which incorporate the following (Fig. 1.
WARNING! DIVE PRACTICES WHICH INCLUDE THE ABOVE DESCRIBED “HIGHER RISK DIVE PROFILES” ARE BELIEVED TO INCREASE THE RISK OF DECOMPRESSION SICKNESS AND AS SUCH CONSIDERED POTENTIALLY DANGEROUS AND SHOULD BE AVOIDED EVEN IF THEY CONFORM TO THE MATHEMATICAL MODEL! WARNING! DO NOT USE THE DIVE COMPUTER WITH NITROX MIX! The mathematical tissue calculation model of the instrument has been designed for use with standard breathing air only (approximately 21% oxygen and 79% nitrogen by volume).
DIVE COMPUTER LIMITATIONS While the instrument is based on current decompression research and technology, the user/ diver must realize that the computer cannot monitor the actual physiological functions of an individual diver. All decompression schedules currently known to the authors, including the U.S. Navy Tables, are based on a theoretical mathematical model which is intended to serve as a guide to reduce the probability of decompression sickness.
2. GETTING ACQUAINTED WITH THE DIVE COMPUTER WARNING! READ AND UNDERSTAND THE ENTIRE OWNER’S MANUAL BEFORE DIVING! Failure to complete this step may result in serious personal injury. The purpose of this section is to provide the user with initial information to preview the operation of the computer. Since this information is limited, it is imperative that you read and understand the entire owner’s manual before attempting to dive. 2.

3. DIVING WITH THE DIVE COMPUTER A S C R A T E m TIME MODE This section contains instructions on how to operate the dive computer and interpret its displays. Each display has been carefully designed to provide important information you will need to plan your dive or dive series. You will find that the ínstrument is easy to use and read. Each display shows only the data relevant to that specific diving situation.
When the TIME/MODE and COM contacts are touched for over three seconds, the display will start to scroll through the following modes. Lift your fingers when the desired mode is displayed: Logbook memory: at LOG the logbook memory is accessed. Dive history memory: at HIS the history memory is accessed. Personal/altitude adjustment setting: at Alt the personal and/or altitude adjustment can be set. Time setting: at Set the time and date can be adjusted.
3.2 LUX/LUX S MODELS: TAP SWITCH AND ELECTROLUMINESCENT BACKLIGHT The tap switch is used to activate the electroluminescent backlight. The switch is used by pressing or tapping the movement sensitive area with your finger. This area is on the face of the instrument between the ON/PLAN and TIME/MODE water contacts marked with a “¤ LUX” symbol. The light can be activated in all modes when the computer is on. The illumination goes off automatically after approximately 10 seconds from activation.

However, it is necessary to turn it on before diving to check the personal/ altitude adjustment setting, battery power, etc.
PERSONAL ADJUSTMENT AND HIGH ALTITUDE DIVING WARNING! SET THE CORRECT PERSONAL/ALTITUDE ADJUSTMENT MODE! When diving at altitudes greater than 700 m [2300 ft] the personal/altitude adjustment feature must be correctly selected in order for the computer to calculate no-decompression status. The diver should also use this option to make the calculations more conservative, whenever it is believed that factors which tend to increase the possibility of decompression sickness exist (see Section 3.6).
BATTERY POWER INDICATOR AND LOW BATTERY WARNING The instrument has a unique visual Battery Power Indicator designed to give you an advance notice of impending need to change the battery. The Battery Power Indicator will always be seen during activation. The following table 3.1 shows the various warning levels (see also Fig. 3.4). TABLE 3.1 BATTERY POWER INDICATOR Display after activation Operation*) Figure five (5) bar graph segments normal, new battery 3.4 a) and four (4) bar graph segments 3.
After activation the Low Battery Warning is indicated by the battery symbol. If the battery symbol is displayed in the surface mode or if the display is faded or weak, the dive computer should not be used (Fig. 3.5). It indicates that the battery is too low to operate the instrument. If the low battery symbol appears during a dive, you should abort the dive and begin ascent to the surface.
A S C R A T E m DIVE NUMBERING SHOWN DURING DIVE PLANNING A1 NO DEC TIME DIVE LOG HIS DIVE TIME ALT SET PLAN Fig. 3.7 DIVE PLANNING The no-decompression time limit at 30.0 m [100 ft] is decreased to 5 minutes in A1 mode after the third dive of the series. A S C R A T E m Several repetitive dives are considered to belong to the same repetitive dive series when the dive computer has not deactivated itself.
3.4 DIVING 3.4.1 Basic Dive Data The dive computer will remain in the SURFACE mode at depths less than 1.2 m [4 ft] (first generation computers 1.8 m [6 ft]). At depths greater than 1.2 m (1.8 m first generation computers) the instrument will go into the DIVE mode. Each piece of information on the display is clearly marked (Fig. 3.9). During a nodecompression dive, the following information will be shown: • • • the available no-decompression time (a) in minutes is shown as NO DEC TIME.
A S C R A T E A S C R A T E m 3.4.2 Reverse No-Decompression Time Bar Graph The available no-decompression time is also shown visually in the multi-function bar graph in the bottom of the display (Fig. 3.10). When your available no-decompression time decreases below 60 minutes, the first bar graph segment appears. As your body absorbs more nitrogen, more segments start to appear.

A S C R A T E 3.4.3 Ascent Rate Indicator m MAX The ascent rate is shown graphically with a pointer in the upper left corner, next to the notation ASC RATE, as follows: A1 NO DEC TIME DIVE TIME C Ascent rate indicator Ascent speed Example in Fig. no. No segments Below 5 m/min [16 ft/min] 3.9 Segment one 5 - 7 m/min [16 - 23 ft/min] 3.10 Segment two 7 - 9 m/min [23 - 30 ft/min] 3.11 Segment three 9 - 11 m/min [30 - 36 ft/min] 3.12 Segment four Above 11 m/min [36 ft/min] 3.
The SLOW warning alternates with the current depth. The SLOW warning is an indication that the maximum ascent rate has been exceeded continuously, whereas the ascent rate indicator shows present ascent speed. Whenever the SLOW warning appears, you should immediately slow down or stop your ascent until the warning disappears. You must not ascend shallower than 3 m [10 ft] with the SLOW warning on. If you reach this depth with SLOW on, you must stop at this depth and wait until the warning disappears.
3.4.4 Alarms The standard and LUX models feature visual alarms, and the LUX S visual as well as audible alarms, to alert you when you are approaching dangerous situations. Potential danger situations during a dive, occurs when: • the no-decompression dive tur ns into a decompression dive. One arrow pointing upwards and the ascend warning CEILING/ASC TIME will appear (Fig. 3.14). LUX S model gives also an audible alarm: three single beeps.

It includes: The time needed to ascend to the ceiling at an ascent rate of 10 m/min [33 ft/min] plus The time needed at the ceiling. The ceiling is the shallowest depth to which you should ascend plus The time needed to reach the surface after the ceiling has been removed. NOTE: Ascent time is not displayed in the Octopus II dive computer (see Figure 3.16).

DIVE TIME C If you start a new dive after less than 10 minutes at the surface, the instrument interprets this as a continuation of the previous dive.
3.5.2 Flying After Diving The no-flying time is shown in the center window next to the non-blinking airplane image. The blinking airplane is a reminder, when the alternative display showing surface time is on (Figures 3.19 and 3.20). Flying or traveling to a higher altitude should be avoided anytime the airplane symbol is displayed. The no-flying time displayed by the dive computer is always at least 12 hours or equivalent to the so-called desaturation time (if longer than 12 hours).
3.6 PERSONAL ADJUSTMENT AND HIGH ALTITUDE DIVES The instrument can be adjusted for increasing the conservatism of the mathematical model or for diving at altitude. WARNING! SET THE CORRECT PERSONAL/ALTITUDE ADJUSTMENT MODE! When diving at altitudes greater than 700 m [2300 ft] the personal/altitude adjustment feature must be correctly selected in order for the computer to calculate no-decompression status.
ALTITUDE ADJUSTABILITY When programming the instr ument for the correct altitude, the diver needs to select the correct altitude mode according to Table 3.2. As a result the dive computer adjusts its mathematical model according to the entered altitude, giving shorter nodecompression times at higher altitudes (Tables 6.1 and 6.2). The entered personal/altitude adjustment mode is indicated by A0, A1, or A2. Section 4.3, Personal/Altitude Adjustment Setting describes how the altitude mode is adjusted.
This feature should be used to adjust the computer to intentionally introduce a factor to make it more conservative according to personal preference by entering a higher altitude mode than required in table 3.2 (i.e. diving at sea level with the personal/ altitude adjustment set at A1 or A2). The no-decompression limits are then shortened accordingly (Tables 6.1 and 6.2).
OMITTED DECOMPRESSION The most common ERROR MODE results from omitted decompression, when the diver stays above the ceiling for more than three minutes. During this three-minute period the Er warning will blink alternating with the CEILING/ASC TIME display. The instrument will continue to function normally, if the diver descends below the ceiling within three minutes. After this the dive computer will enter a permanent ERROR MODE.
4. MENU BASED MODES The menu based functions include the logbook and history memories, the personal/altitude adjustment setting, and the date and time setting. The menu based functions are activated using the water contacts. Keep your fingers on the TIME/MODE and COM contacts while the dive computer scrolls through the menu (Fig. 4.1). The desired mode is selected by breaking the finger contact when the desired mode appears on the display: •LOG: •HIS: •Alt: •Set: Logbook Memory.

5. CARE AND MAINTENANCE The dive computer is a sophisticated precision instrument. Remember to treat it as such! It has been designed to withstand the rigors of scuba diving. It can be installed in a durable thermoplastic console boot and its display can be protected by a replaceable display shield. The user should wash and rinse the unit in fresh water after every use. Protect it from shocks, extreme heat or direct sunlight and chemical attack.
5.1 MAINTENANCE If left without care for an extended period, a thin film (often invisible to the eye) will cover the unit. Much like the buildup on the glass of an aquarium, this film is the result of organic contaminates found in both salt and fresh water. Suntan oil, silicone spray and grease will speed up this process. As a result of this buildup, moisture will be trapped next to the contacts and will not allow your dive computer to operate properly.
CAUTION! Do not use compressed air to blow water off the unit Do not use solvents or other cleaning fluids that might cause damage Do not test or use the dive computer in pressurized air. 5.2 BATTERY COMPARTMENT INSPECTION Frequently check for leaks in the battery compartment. This is important especially after the battery has been replaced. If you find moisture inside the transparent battery compartment lid, there is a leak.
6. TECHNICAL DESCRIPTION 6.1 OPERATING PRINCIPLES The Suunto dive computer is a multi-functional sport diving instrument, which provides information on depths, times and decompression requirements. Its electronic microprocessor mathematically models the absorption and release of nitrogen during all phases of diving, including ascents, surface intervals and repetitive dives.

WARNING! THE USER SHOULD BE AWARE THAT ANY DIVE, INCLUDING ONES WITHIN THE U.S. NAVY TABLES OR DIVE COMPUTER LIMITS, DOES CARRY SOME RISK OF DECOMPRESSION SICKNESS. COMPARTMENTS AND HALF TIMES When you dive with the instrument, it measures and displays depths and times as your dive progresses. It shows you available no-decompression time and possible decompression required based upon the following five factors: 1. your present depth, 2. excess nitrogen absorbed during earlier portions of the dive, 3.
The no-decompression limits in the U.S. Navy tables are based upon six theoretical compartments for single dives, and one compartment for surface intervals and repetitive dives. If you are familiar with table theory, you may know that they are characterized by half times (i.e. the time required for 50 % equilibration to a pressure change) ranging from 5 minutes to 120 minutes. The instrument includes the same six compartments, and two additional compartments for an increased range of the mathematical model.
SURFACE INTERVALS The dive computer requires a minimum surface interval of 10 minutes between dives. If a surface interval is shorter than 10 minutes, the instrument dive counter and dive timer treat the next dive as a continuation of the previous dive. It adds the dive times, and calculates no-decompression limits or decompression stops based on excess nitrogen absorbed on both dives. In this regard, it is similar to the U.S. Navy tables.
