2. Setup and Installation
Before installation, verify your vehicle model, engine type, drive system, year, and grade using your vehicle inspection certificate and compliance plate. Always confirm compatibility on the manufacturer's homepage to avoid errors.
Installation Steps:
- Preparation: Ensure the mounting surface on the vehicle roof is clean and dry. Remove any old gasket material or adhesive residue.
- Gasket Placement: Carefully place the curved rubber gasket between the vehicle's roof and the main body of the Dolphin antenna. This gasket ensures a watertight seal and proper fit.
- Antenna Connection: Select the appropriate antenna connection screw (M4, M5, M6, or Mazda-specific) for your Dolphin antenna model. Securely connect the antenna to the vehicle's existing antenna cable.
- Antenna Body Fixing: Use the four antenna body fixing screws to firmly attach the Dolphin antenna body to the vehicle roof.
Important Considerations:
- Refer to Original Manual: Always consult the original instruction manual for your specific Dolphin antenna model (FDA9/FDA10/FDX9/FDX10) for detailed fixing and connection procedures.
- Roof Flexibility: If your vehicle's roof is soft and prone to denting, it may be necessary to support or lift the roof from the inside of the vehicle during installation to ensure proper and secure mounting.

3. Operating Instructions
The FDAC7B is an accessory kit for the Dolphin antenna and does not have specific operational functions itself. Once correctly installed, the Dolphin antenna will function as intended, receiving radio signals. Refer to your vehicle's audio system manual for operating instructions related to radio reception.
4. Maintenance
To ensure the longevity and performance of your Dolphin antenna and its accessory components, follow these maintenance guidelines:
- Regular Cleaning: Periodically clean the antenna and the surrounding roof area with a mild car wash soap and water. Avoid abrasive cleaners or harsh chemicals that could damage the finish or rubber components.
- Gasket Inspection: Inspect the rubber gasket for any signs of wear, cracking, or deterioration, especially after several years of use or exposure to extreme weather. The FDAC7B kit provides replacement gaskets for this purpose.
- Screw Tightness: Occasionally check the tightness of the antenna body fixing screws to ensure they remain secure. Do not overtighten.
- Avoid High-Pressure Washing: While the antenna is designed to be weather-resistant, direct high-pressure water jets at close range, especially around the base, should be avoided to prevent water ingress or damage to the seal.
5. Troubleshooting
If you encounter issues after installing the accessory kit, consider the following:
- Water Leakage: If water leaks into the vehicle around the antenna base, it indicates an improper seal.
- Ensure the rubber gasket is correctly seated and not pinched or misaligned.
- Verify that the antenna body fixing screws are tightened evenly and securely.
- Check for any damage to the gasket or the antenna base itself.
- Antenna Looseness: If the antenna feels loose after installation:
- Re-check the tightness of all fixing screws.
- If the vehicle roof is soft, ensure it was adequately supported during installation as described in Section 2.
- Poor Radio Reception: While this kit primarily addresses physical mounting, poor reception could indirectly be related to connection issues.
- Ensure the antenna connection screw is properly engaged and tightened to the vehicle's antenna cable.
- Verify that the original Dolphin antenna itself is not damaged.
Note: The manufacturer is not responsible for accidents or malfunctions caused by improper use or installation.
