5.1 Physical Placement

The Jeecoo M20 speakers offer flexible placement options:

• Combined Soundbar Mode: Connect the two speaker units together to form a single soundbar, ideal for placement directly under a monitor.

5.2 Power and Audio Connection (USB Wired Mode)

The Jeecoo M20 speakers are USB-powered and receive audio via the same USB cable. They do not use a traditional 3.5mm (P2) audio jack.

1. Connect the USB cable from the speakers to an available USB port on your PC, laptop, or a USB power bank.
2. Ensure the connection is secure. Your operating system (Windows, Linux, etc.) should automatically recognize the speakers as an audio output device.

6. Operating Instructions

6.1 Power ON/OFF

• Power ON: Short press the multi-function button.
• Power OFF: Press and hold the multi-function button for approximately 3 seconds.

6.2 Volume Control

6.4 Switching Between USB and Bluetooth Modes

The multi-function button primarily controls Bluetooth pairing and RGB, not direct mode switching.

7. Maintenance

• Cleaning: Use a soft, dry cloth to clean the surface of the speakers. Do not use liquid cleaners or aerosols.
• Storage: When not in use for extended periods, store the speakers in a cool, dry place, away from direct sunlight and dust.
• Cable Care: Avoid bending or crimping the USB cable excessively to prevent damage.

8. Troubleshooting

No Sound:

• Ensure the USB cable is securely connected to both the speakers and the power/audio source.
• Check if the speakers are powered on.
• Verify the volume knob on the speakers is turned up.
• Check the volume settings on your connected device (PC, phone, etc.).
• If using USB, ensure the speakers are selected as the default audio output device in your computer's sound settings.
• If using Bluetooth, ensure the speakers are paired and connected to your device.

Bluetooth Pairing Issues:

• Ensure the speakers are in pairing mode (indicator light flashing).
• Make sure your device's Bluetooth is enabled and discoverable.
• Move your device closer to the speakers.
• Try unpairing and re-pairing the speakers from your device's Bluetooth settings.

Speakers do not turn off with PC:

• The speakers do not automatically power off when your PC shuts down. To turn them off, press and hold the multi-function button for 3 seconds.

Low Maximum Volume:

• While the speakers offer good sound quality for their size and price, they are designed for desktop use and may not provide extremely high volume levels suitable for large rooms. Ensure both device and speaker volumes are at maximum.
