This diagram illustrates the physical dimensions of the ATV654 unit, aiding in selecting an appropriate mounting location.
Power Connection
The sound system requires a 12-volt DC power source. Connect the provided power cables directly to your vehicle's battery, ensuring correct polarity (red to positive, black to negative). The inline fuse integrated into the power cable provides protection against electrical surges. It is advisable to connect the unit to a switched power source or install an external switch to prevent parasitic battery drain when the vehicle is off.
Initial Power On
Once securely mounted and wired, power on your vehicle. The unit should power on automatically if connected to a switched power source, or manually if an external switch is used. A power indicator light will confirm the unit is operational.
Operating Instructions
Bluetooth Pairing
- Ensure the ATV654 unit is powered on.
- On your mobile device (smartphone, tablet, etc.), navigate to the Bluetooth settings.
- Search for available devices. The ATV654 should appear as a discoverable device (e.g., "BOSS Audio").
- Select the ATV654 to pair. A confirmation tone or message may indicate successful pairing.
- Once paired, you can stream audio wirelessly from your device to the sound system.
Auxiliary Input (3.5mm)
For devices without Bluetooth, or for a wired connection, use the 3.5mm auxiliary input. Connect one end of the provided 3.5mm audio cable to your audio device's headphone jack and the other end to the AUX-IN port on the ATV654 unit. The unit will automatically switch to AUX mode or may require manual selection (if available).
Volume Control
Volume control is typically managed directly from your connected Bluetooth device or the audio source connected via the auxiliary input. The ATV654 unit itself may have basic touch controls for volume adjustment, depending on the specific model revision.
Maintenance
To ensure the longevity and optimal performance of your BOSS Audio Systems ATV654, follow these maintenance guidelines:
- Cleaning: Regularly wipe down the unit with a soft, damp cloth. Avoid using harsh chemicals or abrasive cleaners, as these can damage the finish and weatherproof seals.
- Weather Protection: While the unit is weatherproof (IPX5 rated), prolonged exposure to extreme conditions (e.g., direct heavy rain, submersion) should be avoided. Ensure all connections are secure and sealed to prevent water ingress.
- Connection Checks: Periodically inspect all wiring and connections for signs of wear, corrosion, or looseness. Tighten any loose connections and replace damaged cables as needed.
- Storage: If storing your ATV/UTV for an extended period, consider disconnecting the sound system from the power source to prevent battery drain.
Troubleshooting
If you encounter issues with your ATV654 sound system, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| No Power | Loose power connection, blown fuse, dead vehicle battery. | Check all power connections. Inspect the inline fuse and replace if blown. Ensure vehicle battery is charged. |
| No Sound | Volume too low, incorrect input selected, device not paired (Bluetooth), faulty audio cable (Aux). | Increase volume on both the unit and connected device. Verify correct input mode. Re-pair Bluetooth device. Test with a different audio cable. |
| Bluetooth Disconnection | Device out of range, interference, low battery on device. | Move device closer to the unit (within 10 meters). Avoid sources of strong electromagnetic interference. Charge your mobile device. |
| Distorted Sound at High Volume | Volume too high, audio source quality. | Reduce volume. Ensure the audio source is of good quality. |
