Setup
1. Charging the Battery
The i330R is equipped with a Lithium Rechargeable battery. Before initial use, fully charge the device using the provided charging cable. Connect the cable to the dive computer and a compatible USB power source. The display will indicate charging status.
2. Connecting the Console
Attach the console hose to your first stage regulator's high-pressure port. Ensure the connection is secure and free from leaks. The console includes the i330R dive computer and a submersible pressure gauge (SPG).
3. Initial Settings
Upon powering on for the first time, you will be prompted to set basic parameters:
- Time and Date: Adjust to your local time zone.
- Units: Select Imperial (feet/psi) or Metric (meters/bar) for depth and pressure readings.
- Gas Mixes: Configure up to three Nitrox mixes (21% to 100% O2) if applicable.
4. DiverLog+ App Connection
The i330R features Bluetooth connectivity for integration with the DiverLog+ app. Download the app to your mobile device. Follow the in-app instructions to pair your dive computer and synchronize dive data.
Operating
1. Powering On/Off
To power on, press and hold any button until the display activates. The device will automatically power off after a period of inactivity or when exiting dive mode after a dive.
2. Navigation
The i330R utilizes a 2-button navigation system. Use the buttons to scroll through menus, confirm selections, and access various functions. Refer to the on-screen prompts for specific actions.
3. Operating Modes
The dive computer supports four operating modes:
- Air: For diving with standard air.
- Nitrox: For diving with enriched air nitrox mixes.
- Gauge: Functions as a bottom timer with depth and time tracking.
- Free Dive: Optimized for freediving activities.
Switch between modes via the main menu. Ensure the correct mode is selected before each dive.
4. Viewing Dive Data
During a dive, the bright color screen displays critical information such as current depth, bottom time, no-decompression limit, and gas pressure. After a dive, access the History Mode to review details of your last 24 dives, including max depth and dive duration.
5. Display Brightness
Adjust the display brightness through the settings menu to optimize visibility and prolong battery life. Lower brightness settings conserve power.
Maintenance
1. Cleaning
After each dive, rinse the dive computer thoroughly with fresh water to remove salt, sand, and other debris. Allow it to air dry completely before storage. Do not use chemical cleaners or solvents.
2. Storage
Store the i330R in a cool, dry place away from direct sunlight and extreme temperatures. Ensure the battery is partially charged (not fully depleted or fully charged for extended periods) for long-term storage.
3. Software Updates
Periodically check for online software updates to ensure your dive computer has the latest features and performance enhancements. Updates can typically be performed via the DiverLog+ app or by connecting the device to a computer (a download cable might be needed, sold separately).

- Display Not Responding: Ensure the battery is charged. Try performing a soft reset by holding both buttons for 10 seconds.
- Battery Not Charging: Verify the charging cable is securely connected and the USB power source is functional. Try a different cable or power source.
- Bluetooth Connection Issues: Ensure Bluetooth is enabled on your mobile device and the i330R. Restart both devices and try pairing again. Check the DiverLog+ app for troubleshooting tips.
