Dive Modes and Settings

The Cressi Leonardo offers versatile dive modes, including Air, Nitrox, and Gauge. It allows for adjusting the Partial Oxygen Pressure (PO2) between 1.2 and 1.6 bar, ensuring safety and flexibility for various dives.

Air, Nitrox, and Gauge Modes

The Cressi Leonardo dive computer provides three primary dive modes to accommodate different diving needs. The Air mode is designed for standard recreational dives using compressed air. The Nitrox mode enables divers to use enriched air mixtures, allowing for longer bottom times by adjusting the oxygen percentage. This mode requires careful input of the Nitrox mix to ensure accurate decompression calculations. Lastly, the Gauge mode is a basic setting that provides depth and time information, without any decompression calculations, making it suitable for technical or experienced divers who prefer to manage their own decompression schedules. This mode is also used when diving with other breathing gases.

Adjusting Partial Oxygen Pressure (PO2)

The Cressi Leonardo dive computer allows divers to adjust the Partial Oxygen Pressure (PO2) settings to ensure safe diving practices, particularly when using Nitrox. The device is factory set with a PO2 value of 1.4 bar, however, divers can modify this setting within a range of 1.2 bar to 1.6 bar, with increments of 0.1 bar. This adjustment is vital for matching the computer’s calculations to the specific Nitrox mix used. Proper PO2 setting ensures the computer accurately tracks oxygen exposure, preventing oxygen toxicity issues. It is crucial to understand the implications of these settings and to adjust them correctly based on the planned dive profile and gas mixture. Incorrect settings can lead to unsafe diving conditions.

Safety Features and Decompression

The Cressi Leonardo utilizes the Cressi RGBM algorithm for decompression calculations, providing vital safety information. It displays decompression data, including surface intervals, and warns divers of potential risks during a dive.

Cressi RGBM Algorithm

The Cressi Leonardo dive computer employs the Cressi Reduced Gradient Bubble Model (RGBM) algorithm, a sophisticated system designed to manage decompression requirements during dives. This algorithm is crucial for calculating safe ascent rates and decompression stops, aiming to minimize the risk of decompression sickness; The RGBM algorithm takes into account various factors, including depth, time, and previous dive history, to provide accurate and reliable information to the diver. It’s a key component for ensuring safety during recreational dives, and it is designed to adapt to different dive profiles. The algorithm is integrated into the Leonardo to offer a comprehensive solution for dive management, and provides crucial information related to decompression, surfacing, and surface interval times. The Cressi RGBM algorithm contributes significantly to the computer’s reliability and overall safety.

Decompression Information and Warnings

The Cressi Leonardo dive computer provides vital decompression information and warnings to ensure divers stay within safe limits. Should a diver exceed no-decompression limits, the computer will display the necessary decompression stop information, including depth and duration. The Leonardo clearly indicates ascent rate, helping divers maintain a safe speed during their return to the surface, minimizing the risk of decompression sickness. It provides surface interval time information, allowing divers to plan subsequent dives. The device also features audible and visual warnings to alert the diver to potentially hazardous situations, such as rapid ascents or approaching decompression limits. These warnings are crucial to maintain a safe diving experience, and the displayed data is clear and easy to understand. The Cressi Leonardo effectively manages decompression, giving divers the information needed to complete dives safely.

Troubleshooting and Maintenance

Addressing common issues like decompression signal errors and backlight problems is crucial for optimal performance. Regular maintenance and understanding of potential malfunctions will ensure the Cressi Leonardo’s reliability.

Addressing Decompression Signal Issues

A decompression signal appearing on your Cressi Leonardo, while seemingly alarming, is a critical safety feature designed to protect divers. If this signal activates, it indicates that the no-decompression limits have been exceeded, requiring the diver to perform a controlled ascent and potentially a decompression stop. The Leonardo uses the Cressi RGBM algorithm to calculate these limits, ensuring accurate and reliable information. It is important to understand that the computer is factory set with a Partial Oxygen Pressure (PO2) value of 1.4 bar, which provides maximum safety. However, this can be adjusted between 1.2 and 1.6 bar. If the decompression signal appears unexpectedly or persists, consult the user manual and avoid further diving until the issue is resolved. Ensure proper planning and adherence to dive profiles to minimize decompression risks.

Backlight Functionality Problems

Experiencing issues with the backlight on your Cressi Leonardo can significantly impact underwater visibility, especially in low-light conditions. If the backlight is not functioning, the first step is to check the battery level, as a low battery is a common culprit. Ensure that the battery is properly installed and not corroded. If the battery is fine, review the user manual for specific instructions on activating the backlight, as some models require a specific button combination. If problems persist, and you have tried all solutions in the manual, there may be a malfunction in the unit. It is best to contact Cressi support or an authorized service center for assistance, as attempting to repair it yourself may void the warranty. Do not attempt to dive in low-visibility conditions if you are unable to resolve the backlight issue.
