What should you do if you forget to set your enriched air computer before a dive?

If you forget to set your enriched air computer before a dive, it is likely to enter an error mode. This occurs because the computer relies on specific information regarding the gas mixture being used, such as its oxygen content and the associated parameters for dive planning and monitoring. When this information isn't set, the computer cannot accurately calculate no-decompression limits, ascent rates, or any necessary safety stops. Therefore, it may assume that the dive exceeds safe parameters or display an error message, indicating a malfunction or improper setup.

Diving with an improperly set computer can lead to dangerous situations, as the diver may unintentionally exceed limits that are critical for reducing the risk of decompression sickness. Proper pre-dive checks and settings are essential for safe diving practice, especially when using enriched air. Always ensure that the computer is set accurately according to the gas mixture before diving to avoid complications during the dive.
