Suunto Ocean User Guide

All computers experience failures. It is possible that this device may suddenly fail to provide accurate information during your dive. Always use a backup dive device and only dive with a buddy.

Because any decompression model is purely theoretical and does not monitor the actual body of a diver, there is always a risk of decompression illness (DCI) for any dive. An individual’s physiological makeup can vary from day to day. The dive computer cannot account for these variations. You are strongly advised to remain well within the exposure limits provided by the dive computer to minimize the risk of DCI.

If you suspect risk factors that tend to increase the possibility of DCI exist, Suunto recommends that you use the personal setting to make calculations more conservative and consult a physician with experience in diving medicine before you dive.

When diving at altitudes greater than 300 m (980 ft), the altitude setting must be correctly selected for the computer to calculate the decompression status. Failure to select the correct altitude setting or diving above the maximum altitude limit will result in erroneous dive and planning data. It is recommended that you acclimatize to the new altitude before diving. Always use the same personal and altitude adjustment settings for the actual dive and for the planning.

Suunto strongly recommends that the device not be used for any commercial or professional diving activities. The demands of commercial or professional diving may expose the diver to depths and conditions that tend to increase the risk of DCI.

Before diving, always check that your dive computer is functioning properly, the display is working, the battery level is OK, tank pressure is correct, and your settings are correct.

Check your dive computer regularly during a dive. If you believe or conclude that there is a problem with any computer function, abort the dive immediately and safely return to the surface. Contact Suunto customer support and return your computer to an authorized Suunto Service Center for inspection.

The dive computer should never be traded or shared between users while in use. 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. No dive computer can take into account dives made without the computer. Thus, any diving activity up to four days prior to initial use of the computer may cause misleading information and must be avoided.

For safety reasons, you should never dive alone. Dive with a designated buddy. You should also stay with others for an extended time after a dive as the onset of possible DCS may be delayed or triggered by surface activities.

ONLY TRAINED DIVERS SHOULD USE A DIVE COMPUTER! Insufficient training for any kind of diving, including freediving, may cause a diver to commit errors, such as incorrect use of gas mixtures or improper decompression, that may lead to serious injury or death.

Do not participate in freediving and scuba diving activities on the same day.

This device is recommended for use with compressed air. The compressed air supply must comply with the quality of compressed air specified in the EU standard EN 12021:2014 (requirements for compressed gases for breathing apparatus). This device can also be used with enriched air (nitrox) breathing gases.

Diving with mixed gases has dangers that are not familiar to divers diving with air. Appropriate training courses for diving with enriched air is essential prior to the use of this kind of equipment with oxygen content greater than 21%.

In nitrox use, the maximum operating depth and no decompression time are dependent on the oxygen content of the gas. When the oxygen limit fraction indicates that the maximum limit is reached, you must immediately take action to reduce oxygen exposure. Failure to take action to reduce oxygen exposure after a CNS%/OTU warning is given can rapidly increase the risk of oxygen toxicity, injury, or death.

Do not dive with gas if you have not personally verified its content and entered the analyzed value into your dive computer. Failure to verify tank contents and enter the appropriate gas values where applicable into your dive computer will result in incorrect dive planning information.

YOU ARE ADVISED TO AVOID FLYING ANY TIME THE COMPUTER COUNTS DOWN THE NO-FLY TIME. ALWAYS ACTIVATE THE COMPUTER TO CHECK THE REMAINING NO-FLY TIME PRIOR TO FLYING! Flying or traveling to a higher altitude within the no-fly time can greatly increase the risk of DCS. Review the recommendations given by Divers Alert Network (DAN). There can never be a flying-after-diving rule that is guaranteed to completely prevent decompression sickness!

If you have a pacemaker, we recommend you do not scuba dive. Scuba diving creates physical stresses on the body which may not be suitable for pacemakers.

You must read the printed quick guide and online user guide of your dive computer. Failure to do so may lead to improper use, serious injury or death.
