2. Setup

2.1. Installazzjoni tal-batterija

The SEAC Action HR uses a long-lasting CR2450 battery. To install or replace the battery, carefully unscrew the battery cover located on the back of the unit. Insert the new CR2450 battery with the positive (+) side facing up. Ensure the O-ring is clean and properly seated before securely fastening the battery cover. This ensures the unit's water resistance.

2.2. L-Ewwel Tixgħil u s-Settings Bażiċi

Upon first power-on or after battery replacement, the device will prompt you to set basic parameters such as time, date, and measurement units (metric/imperial). Use the control buttons (typically labeled "MODE", "LIGHT", "ST/STP/+", "RESET/-") to navigate through the menus and adjust settings. Refer to the on-screen prompts for guidance.

3. Modi Operattivi

The SEAC Action HR features three primary operating modes:

3.1. Dive Mode (Scuba)

This mode provides full management of recreational immersion profiles. It utilizes the Bühlmann ZHL-16c decompression algorithm and supports 1 or 2 gas mixes, including Air, Nitrox, and mixes with O2 concentrations up to 99%. Key information displayed includes current depth, dive time, no-decompression limit (NDL), ascent rate, and safety stop information.

3.2. Gauge Mode

In Gauge Mode, the computer functions as a depth gauge and stopwatch, allowing independent management of immersion profiles. This mode is suitable for technical diving or situations where a simple depth and time reference is preferred without decompression calculations.

3.3. Freediving Mode

Designed for freediving, this mode tracks dive time, surface interval time, current depth, and maximum depth achieved during a freedive. It provides essential data for monitoring freediving performance and recovery times.

4. Logbook and Data Management

The SEAC Action HR stores your dive data in its internal logbook:

• Dive Mode Logbook: Stores up to 40 hours of dive data with records taken every 5 seconds.
• Freediving Mode Logbook: Stores up to 18 hours of activity with records taken every 2 seconds.

To download your dive data, connect the computer to your Mac or PC using a compatible USB cable (sold separately). The "Dive Manager" software is available for free download from the official Seacsub.com website. Please note that the software requires a minimum of Windows 10 for PC compatibility.

5. Karatteristiċi ta' Sigurtà u Allarmi

The SEAC Action HR is equipped with several safety features and audible/visual alarms to ensure a safe diving experience:

• MOD (Maximum Operating Depth) Alarm: Alerts you when you exceed the programmed maximum operating depth for your gas mix.
• Decompression Stop Violation Alarm: Warns if a required decompression stop is missed or violated.
• Ascent Rate Alarm: Notifies you if your ascent rate is too fast, helping to prevent decompression sickness.
• No-Fly Time Calculation: Provides the recommended surface interval before flying after a dive.
• Desaturation Time Calculation: Indicates the time required for your body to desaturate from nitrogen.
• Maximum Allowed Altitude: Displays the maximum altitude at which the computer can be safely used for diving.
• Dive Planner ("NDL Only"): A planning tool to calculate no-decompression limits for future dives.

6. Manutenzjoni

6.1. Post-Dive Care

After each dive, rinse your SEAC Action HR thoroughly with fresh water to remove salt, sand, and other debris. Pay special attention to the buttons and the strap. Allow the unit to air dry completely before storage. Avoid using harsh chemicals or abrasive materials for cleaning.

6.2. Sostituzzjoni tal-batterija

The CR2450 battery is designed for long life. When the low battery indicator appears, replace the battery promptly to ensure continuous operation and data integrity. Always use a new, high-quality CR2450 battery and ensure the O-ring is clean and properly sealed during reassembly to maintain water resistance.

6.3. Ħażna

Store the dive computer in a cool, dry place away from direct sunlight and extreme temperatures. Ensure it is clean and dry before storing for extended periods.

The SEAC Action HR features an ultra-robust structure, treated for enhanced resistance to impacts, corrosion, and thermal variations. However, proper care is still essential for its longevity.
