Introduction
This manual provides essential information for the proper use, setup, operation, and maintenance of your Cressi Leonardo Console 2. The Leonardo Console 2 integrates the Leonardo dive computer with a pressure gauge into a modern, compact design. This console is engineered for ease of use and readability, utilizing advanced materials to minimize weight and bulk, ensuring a reliable and safe diving experience.
Product Overview and Features
The Cressi Leonardo Console 2 is a robust and user-friendly instrument designed for scuba diving. It combines a digital dive computer with an analog pressure gauge, providing critical information at a glance.

- Dive Computer: Features a wide UFDS (User-Friendly Display System) display for easy navigation and readability. It supports Air, Nitrox, and Gauge modes. Nitrox management includes FO2 adjustable between 21% and 50%, and PO2 adjustable between 1.2 BAR and 1.6 BAR. It also provides a CN5 oxygen toxicity graphic indicator and a deactivable Deep Stop alert. The algorithm incorporates RGBM and a Modified Haldane and Wienke algorithm. An ascent rate alarm is set at 10 meters per minute.
- Pressure Gauge: A rugged, chrome-plated brass case houses the analog pressure gauge. It is color-coded in red, green, and blue for instant readability and accurately reads pressures up to 350 BAR / 5000 PSI.
- Ergonomic Design: The console is angled to fit naturally in the hand, positioning both the pressure gauge and computer for optimal viewing during dives.
- Mounting Options: Equipped with two connection points: one at the top for a clip or bungee, and wide loops on the back for connection to any strap, offering versatile mounting solutions.
- Durable Materials: Constructed from polycarbonate and desmopan materials, contributing to its lightweight nature and reduced drag underwater.
- Battery: Features extended battery life through a combination of systems, including a battery saver mode and automatic power-on. It uses one CR2430 battery, which is included.
- Optional Interface: An optional Leonardo Interface (not included) is available for downloading dive sessions to a PC or Mac for detailed analysis.

Setup
Before your first dive, ensure the console is properly prepared and configured.
- Battery Installation: The console comes with a CR2430 battery pre-installed. If replacement is needed, carefully open the battery compartment, replace the battery, and ensure the O-ring is clean and properly seated to maintain a watertight seal.
- Hose Connection: Connect the console's high-pressure (HP) hose to the HP port on your first stage regulator. Ensure the connection is secure and hand-tightened. The hose has a reduced diameter (11 mm / 0.43 in) for enhanced flexibility.
- Initial Configuration: Upon activation, the Leonardo computer will guide you through initial setup. This typically includes setting units of measurement (Imperial/Metric), time, date, and any specific Nitrox parameters if you plan to dive with enriched air. Refer to the on-screen prompts for navigation.
- Mounting: Utilize the top connection point for a clip or bungee, or the wide loops on the back to secure the console to your BCD or other diving equipment.
Operating Instructions
Understanding how to operate your Cressi Leonardo Console 2 is crucial for safe diving.
- Power On/Off: The computer automatically powers on when submerged or when a button is pressed. It enters a battery saver mode when not in use and powers on automatically when activity is detected.
- Navigation: Use the designated buttons to navigate through menus and access various dive data screens. The UFDS display is designed for intuitive interaction, making information readily accessible.
- Selecting Dive Modes: Before each dive, select the appropriate dive mode (Air, Nitrox, or Gauge) based on your dive plan and gas mixture. For Nitrox, confirm the FO2 and PO2 settings.
- Pre-Dive Check: Always perform a pre-dive check. Verify the pressure gauge reads correctly when the tank valve is open. Check the computer's battery level, current time, and selected dive mode.
- During the Dive: Continuously monitor your depth, dive time, no-decompression limits, and tank pressure. Pay close attention to any ascent rate alarms or deep stop alerts issued by the computer.
- Post-Dive Review: After surfacing, the computer will display a summary of your dive. You can access detailed dive logs through the menu. For comprehensive analysis, consider using the optional Leonardo Interface to download dive data to a computer.

Maintenance
Proper maintenance ensures the longevity and reliability of your Cressi Leonardo Console 2.
- Rinsing: After every dive, thoroughly rinse the entire console with fresh, clean water. Ensure all salt and debris are removed, especially from buttons and crevices.
- Drying: Allow the console to air dry completely in a shaded, well-ventilated area before storage. Avoid direct sunlight, which can degrade materials.
- Storage: Store the console in a cool, dry place, away from extreme temperatures, direct sunlight, and chemicals. Protect it from physical impact.
- Battery Replacement: When the low battery indicator appears, replace the CR2430 battery promptly. Follow the instructions for opening the battery compartment, ensuring the O-ring is clean, lubricated (if recommended by Cressi), and correctly seated before securely closing the compartment to maintain its watertight integrity.
- Regular Inspection: Periodically inspect the console body, hose, and connections for any signs of wear, cracks, or damage. If any damage is found, do not use the console and have it inspected by a qualified Cressi technician.
Troubleshooting
This section addresses common issues you might encounter with your Cressi Leonardo Console 2.
- Blank Display: If the computer display is blank, first check the battery level. If the battery is low or depleted, replace it. Ensure the battery is installed correctly and the compartment is sealed. If the issue persists after battery replacement, contact Cressi support.
- Inaccurate Pressure Gauge Reading: If the analog pressure gauge provides an incorrect or stuck reading, do not use the console for diving. This indicates a potential malfunction that requires professional inspection and repair.
- Computer Alarms: Understand the meaning of various alarms (e.g., rapid ascent, decompression violation, low battery). Always respond appropriately to alarms to ensure dive safety. Consult the full user manual for a complete list of alarms and their meanings.
- Difficulty Navigating Menus: If you find it difficult to navigate the computer's menus, refer to the detailed instructions in the comprehensive user manual for specific button functions and menu structures.
