Setup Instructions
- Unpack Components: Carefully remove the speaker unit and mounting bracket from the packaging. Inspect for any signs of damage.

Operating Instructions
- Power On: Once the TH-650 horn speaker is correctly installed and connected to a compatible driver unit and amplifier, power on your audio system.
- Adjust Volume: Start with the amplifier volume at a low setting and gradually increase it to the desired listening level. Avoid excessively high volumes that could cause distortion or damage to the driver unit.
- Monitor Sound Quality: Listen for clear, undistorted sound. If distortion occurs, reduce the volume or check connections.
- Environmental Considerations: While weatherproof, extreme weather conditions (e.g., direct lightning strikes, prolonged submersion) should be avoided.
Maintenance
The TH-650 horn speaker is designed for durability and requires minimal maintenance.
- Regular Cleaning: Periodically wipe the exterior of the speaker with a soft, damp cloth to remove dust and dirt. Avoid using harsh chemicals or abrasive cleaners.
- Inspect Connections: Annually, inspect all wiring connections for corrosion or looseness. Ensure the driver unit remains securely attached to the horn.
- Check Mounting: Verify that the mounting bracket and speaker are still securely fastened to their support structure, especially after severe weather conditions.
- Weather Protection: Although weatherproof, consider additional protection in environments with extreme salt spray or industrial pollutants to prolong the lifespan of the finish.
