6. Maintenance

• Lens Cleaning: Use the provided lens cloth to gently clean the goggle lenses. Avoid abrasive materials or harsh chemicals that could scratch or damage the optical surfaces.
• Dust Prevention: The optical module is fully enclosed and dust-resistant. However, always store the goggle in its hard case when not in use to minimize dust exposure.
• Fan Maintenance: The three independently addressable fans help cool the internals and prevent fogging. Ensure the fan vents are clear of obstructions. No user-serviceable parts are associated with the fans.
• Storage: Store the goggle in the included hard case to protect it from physical damage and environmental elements during transport and storage.
• Software Updates: Periodically check the official HDZero website or community forums for firmware updates. Keeping your goggle's software up-to-date can improve performance and add new features.

7. Troubleshooting

• No Power: Ensure the XT60 cable is securely connected to both the goggle and a charged 2S-6S battery. Check the on/off switch is in the 'On' position.
• No Video Signal (Digital): Verify your HDZero VTX is powered on and transmitting. Check antenna connections on both the goggle and VTX. Ensure the goggle is set to the correct HDZero channel.
• No Video Signal (Analog): Confirm your analog video source is active and connected to the 3.5mm AV input. Check antenna connections.
• Blurry Image: Adjust the IPD sliders and focus dials until the image is clear for both eyes. If using diopter lenses, ensure they are correctly inserted and suitable for your vision.
• Fogging Lenses: The goggle's internal fans are designed to prevent fogging. Ensure the fans are operating and their vents are not blocked. If fogging persists in high humidity, try increasing fan speed via the goggle menu.
• Poor Analog Reception: The Goggle 2 features enhanced analog reception. If experiencing weak signals, ensure your analog antennas are correctly oriented and consider using higher-gain antennas.
• WiFi Mirroring Issues: Ensure the WiFi module is enabled in the goggle settings. Check your phone/PC's WiFi connection and ensure it's connected to the goggle's network. Restarting both devices can sometimes resolve connectivity issues.
• DVR Recording Problems: Check if a compatible microSD card is inserted and has sufficient free space. Ensure the recording function is activated in the menu.
