2. Setup Guide

2.1 Watertight Safety Test (Mandatory Before First Use)

Before placing your phone inside, perform a watertight test to ensure the case is sealed correctly:

1. Place a tissue inside the case.
2. Seal both the case and the vacuum cover securely.
3. Fully submerge the case in water for 30+ minutes.
4. Do not open the case immediately after retrieval.
5. Check if the tissue remains dry. If dry, the waterproof seal is verified. If wet, contact official support.

2.2 Bluetooth Pairing

2. On your phone, go to Bluetooth settings and connect to "TELESIN SDC".

Note: The device will auto-shutdown after 2 minutes if unpaired.

2.3 iOS Initial Setup (One-Time Only)

For iOS devices, a one-time setup is required for full functionality:

1. Go to Settings → Accessibility → Zoom.
2. Select Zoom Region and choose Full Screen Zoom.
3. Enable Zoom.

Note: When Zoom is enabled, the screen magnifies. Triple-tap with two fingers to reset the view. Other settings should remain unchanged. This step is not required for Android devices, as full features unlock via Bluetooth.

2.4 Phone Settings for Optimal Use

To prevent interruptions during underwater shooting:

• Enable Do Not Disturb Mode on your smartphone to prevent notifications and interruptions.

2.5 Phone Installation Procedure

Follow these steps to correctly install your phone into the case:

1. Unlock all 5 latches on the case and open the cover.
2. Remove your phone from any existing phone case to ensure a bare-metal installation for better shooting results.
3. Carefully align your phone's lens with the viewport of the diving case.
4. Flush the phone against the left edge of the case and secure it in the internal clamp.
5. Test: Switch your phone's camera to the widest lens setting. If the view is blocked, adjust the phone slightly rightward (e.g., for iPhone 12 Mini).
6. Close the cover and lock all latches securely.
7. Unscrew the vacuum port counterclockwise.
8. Press the rubber head of the vacuum pump firmly onto the port and pump 3-4 times to remove air.
9. Tighten the vacuum port clockwise. This process prevents air condensation and eliminates lens/screen fogging.

For added security, especially during freediving or scuba diving where hands-free operation might be needed (e.g., ear equalization, hand signals), attach the safety leash to your wrist.

4. Maintenance

4.1 Cleaning

• After each use, especially in saltwater, rinse the case thoroughly with fresh water.
• Wipe the case dry with a soft cloth. Use the included lens cloth for the viewport to avoid scratches.
• Ensure no sand or debris is lodged in the latches or seals.

4.2 Storage

• Store the case in a cool, dry place away from direct sunlight.
• Do not store with latches closed tightly for extended periods to prevent deformation of the rubber seals.

4.3 Battery Charging

• Charge the diving handle using the provided USB charging cable via the Pogo Pin charging port.
• A full charge takes approximately 2 hours.

5. Troubleshooting

• Fogging inside the case: Re-perform the vacuum pumping procedure to ensure all air is removed.
• Water ingress: If the watertight safety test fails (tissue gets wet), do not use the case. Contact official support immediately.
• Bluetooth not connecting: Ensure the diving handle is powered on. Try unpairing and re-pairing the device. Remember, the device auto-shuts down after 2 minutes if unpaired.
• Buttons not responding: Check that your phone is correctly aligned within the case and that the Bluetooth connection is active.
• Screen magnification (iOS): If the screen is magnified due to the iOS Zoom accessibility feature, triple-tap the screen with two fingers to reset the view.

• Bare-Metal Installation: For the best fit and optimal shooting results, always remove your phone from its regular protective case before installing it into the diving case.
• Prevent Interruptions: Always enable 'Do Not Disturb' mode on your phone before diving to avoid incoming calls or notifications that could disrupt your shooting or potentially affect the phone's functionality underwater.
• Safety First: Always use the provided safety leash, especially during dynamic underwater activities, to prevent accidental loss of the device.
