4.1 ערשטע אַקטיוואַציע

The Donatello Dive Computer typically comes pre-installed with a battery. Upon first use, the device should activate automatically. If not, press and hold the single button for a few seconds to power it on.

4.2 Basic Settings Configuration

Upon initial activation or after a battery change, you may need to configure basic settings such as units of measurement (metric/imperial), time, and date. Use the single button to navigate through the menu options and confirm selections. Refer to the 'Operating Modes' section for general button navigation.

4.3 באַטאַרייע ייַנמאָנטירונג / פאַרבייַט

The Cressi Donatello features a user-replaceable CR2430 battery. To replace the battery:

5. אַפּערייטינג מאָדעס

The Cressi Donatello offers four distinct operating modes, each tailored for specific diving activities. The single button is used for navigation and selection.

5.1 General Button Navigation

• קורץ דרוק: Scrolls through information or menu options.
• לאנג פּרעס: Enters a menu, confirms a selection, or switches modes (depending on context).

5.2 Air Mode

This mode is for diving with standard compressed air. It calculates no-decompression limits, ascent rates, and safety stops based on the Cressi RGBM algorithm. Key information displayed includes current depth, maximum depth, no-decompression time, dive time, and temperature.

5.3 Nitrox Mode

For diving with enriched air nitrox mixtures. Before diving in Nitrox mode, you must set the oxygen percentage (FO2) and partial pressure of oxygen (PO2) limit according to your dive plan. The computer will then calculate decompression limits accordingly, also displaying CNS oxygen toxicity levels.

5.4 Gauge Mode

This mode functions as a bottom timer, providing current depth, maximum depth, average depth, and dive time in minutes and seconds. It does not provide decompression information, making it suitable for technical diving where divers manage their own decompression. Always use a separate, reliable timing device in this mode.

5.5 Apnea Mode (Free Diving)

Designed for freediving, this mode displays real-time depth, maximum depth, dive time, and surface interval. It tracks consecutive dives and surface recovery times, which are crucial for freediving safety.

6. וישאַלט

6.1 רייניקונג און סטאָרידזש

• After each dive, rinse the computer thoroughly with fresh water to remove salt, sand, and chlorine.
• Allow the computer to air dry completely before storage.
• Store the computer in a cool, dry place, away from direct sunlight and extreme temperatures.
• Avoid contact with solvents, chemicals, or sharp objects that could damage the display or casing.

6.2 באַטערי קער

Regularly check the battery indicator. Replace the battery as soon as the low battery warning appears. Always use a new, high-quality CR2430 battery. Ensure the O-ring is clean and properly seated during battery replacement to maintain water integrity.
