- Ensure the box is mounted in an orientation that allows for proper cable management and access to the amplifier controls if needed.
3.2 Connecting Speakers
The amplifier is designed for passive speakers with 4-8 Ohm impedance. Ensure your speakers meet these requirements.
- Open the waterproof box.
- Connect your passive speakers to the speaker output terminals on the amplifier. The terminals are typically color-coded (red for positive, black for negative).
- Carefully route the speaker wires through the designated access ports at the bottom of the waterproof box. Ensure a tight seal around the wires to maintain waterproofing.
3.3 Connecting Power
- Connect the AC power cord to the power interface on the amplifier.
- Route the power cord through an access port in the waterproof box, ensuring a secure and waterproof connection.
- Plug the AC power cord into a standard electrical outlet.

4. Operating Instructions
This section details how to operate your CAMWAY Bluetooth Audio Amplifier.
4.1 Powering On/Off
- Locate the power switch on the amplifier unit.
- Flip the switch to the 'ON' position to power on the amplifier. The Power/Bluetooth Indicator Light will illuminate.
- To power off, flip the switch to the 'OFF' position.
4.2 Bluetooth Pairing
- Ensure the amplifier is powered on and the Bluetooth indicator light is blinking, indicating it is in pairing mode.
- On your smartphone or tablet, navigate to the Bluetooth settings.
- Search for available devices. The amplifier should appear as "BT HIFI AUDIO" or a similar name.
- Select the amplifier from the list to pair. Once successfully paired, the Bluetooth indicator light will become solid.
- You can now stream audio wirelessly from your device to the amplifier.
4.3 Volume Control
- Adjust the master volume using the Volume Knob on the amplifier unit.
- Further volume adjustments can be made directly from your connected Bluetooth device.

5. Maintenance
To ensure the longevity and optimal performance of your CAMWAY Bluetooth Audio Amplifier, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to clean the amplifier and the waterproof box. Avoid using harsh chemicals or abrasive cleaners, as they may damage the surfaces.
- Waterproof Seal: Regularly inspect the rubber gaskets and seals of the waterproof box to ensure they are intact and free from debris. A compromised seal can lead to water ingress and damage to the amplifier.
- Cable Connections: Periodically check all cable connections (speaker wires, power cord) to ensure they are secure and free from corrosion. Loose connections can affect audio quality and safety.
- Storage: If storing the amplifier for an extended period, especially in harsh conditions, ensure it is powered off, disconnected from power, and the waterproof box is securely closed.
6. Troubleshooting
If you encounter issues with your CAMWAY Bluetooth Audio Amplifier, refer to the following troubleshooting tips:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power/No indicator light | Power cord not connected; Power outlet not working; Amplifier power switch is off. | Ensure power cord is securely plugged in; Test power outlet with another device; Flip power switch to 'ON'. |
| No sound from speakers | Speaker wires incorrectly connected; Speakers are not passive or incompatible impedance; Volume too low; Bluetooth not connected. | Check speaker wire polarity and connection; Verify speaker type and impedance (4-8 Ohms); Increase volume on amplifier and source device; Re-pair Bluetooth device. |
| Bluetooth connection issues | Device too far; Interference; Amplifier not in pairing mode; Previously paired device connected. | Move device closer to amplifier (within 15m/50ft); Reduce interference from other wireless devices; Power cycle amplifier to enter pairing mode; Disconnect from other Bluetooth devices. |
| Distorted audio | Volume too high; Poor quality audio source; Speaker impedance mismatch. | Reduce volume; Use a higher quality audio source; Ensure speakers are 4-8 Ohms and within recommended power limits. |
