Locate the TX/RX switch on the side of the device. Slide the switch to select your desired operating mode:

• RX (Receiver) Mode: For receiving Bluetooth audio from your phone/tablet and outputting to wired speakers/headphones.
• TX (Transmitter) Mode: For transmitting audio from non-Bluetooth devices (TV, PC) to Bluetooth headphones/speakers.

Operating Instructions

1. RX Mode (Bluetooth Receiver)

In RX mode, the M10 receives Bluetooth audio from your smartphone, tablet, or other Bluetooth-enabled device and outputs it to a wired speaker, amplifier, or headphones.

1. Slide the TX/RX switch to RX.
2. Connect the M10 to your wired speaker/amplifier/headphones using the 3.5mm AUX cable or RCA audio cable.
3. On your smartphone or tablet, enable Bluetooth and search for "VAORLO M10" (or similar) in the list of available devices.
4. Select the M10 to pair. Once paired, the LED display will indicate a successful connection.
5. Play audio on your connected device. The sound will now be output through your wired audio system.

Note: The M10 supports connecting two mobile phones simultaneously in RX mode, but only one phone's audio can be played at a time. The built-in microphone supports hands-free calling in RX mode.

2. TX Mode (Bluetooth Transmitter)

In TX mode, the M10 transmits audio from non-Bluetooth devices (like TVs, PCs, MP3 players) to Bluetooth headphones or speakers.

1. Slide the TX/RX switch to TX.
2. Connect the M10 to your non-Bluetooth audio source (e.g., TV, PC) using the 3.5mm AUX cable or RCA audio cable.
3. Put your Bluetooth headphones or speaker into pairing mode.
4. The M10 will automatically search for and connect to nearby Bluetooth audio devices. Once connected, the LED display will confirm.
5. Play audio on your source device. The sound will now be transmitted wirelessly to your Bluetooth headphones or speaker.

Note: In TX mode, the M10 acts as a bridge and will not appear in your TV's or PC's Bluetooth device list. It connects directly to your Bluetooth headphones/speakers. The built-in microphone is not supported in TX mode.

3. FM Transmitter Mode

The M10 can transmit audio to your car stereo or any FM radio by tuning to a specific FM frequency.

1. Ensure the M10 is in RX mode (for receiving audio from your phone) or TX mode (for receiving audio from a wired source).
2. Press the 'FM' button on the M10 to activate FM transmission.
3. Use the '+' and '-' buttons to adjust the FM frequency on the M10.
4. Tune your car radio or FM receiver to the same frequency displayed on the M10.
5. Once matched, audio from the M10 will play through your FM radio.

Note: The FM function is for transmission only and does not support receiving FM radio broadcasts. The built-in microphone supports hands-free calling in FM mode.

4. USB U-Disk Playback

The M10 supports direct playback of audio files from a USB flash drive.

1. Insert a USB flash drive (up to 128GB, formatted FAT12/FAT16/FAT32/exFAT) into the USB port on the M10.
2. The device will automatically detect the USB drive and begin playing supported audio formats (MP3/APE/FLAC/WAV/WMA/ALAC/M4A).
3. Use the control buttons on the M10 to play/pause, skip tracks, and adjust volume.

Troubleshooting

If you encounter issues with your VAORLO M10, please refer to the following common troubleshooting steps:

• Device not powering on: Ensure the device is fully charged. Connect it to a power source using the Type-C cable and try again.
• No sound output:
  • Check if the M10 is in the correct RX or TX mode.
  • Verify all audio cables (AUX, RCA) are securely connected.
  • Ensure the volume on both the M10 and the connected audio device (speaker, headphones, phone) is turned up.
  • Confirm successful Bluetooth pairing in RX or TX mode.
• Cannot pair with Bluetooth device:
  • Make sure the M10 is in the correct mode (RX for receiving, TX for transmitting).
  • Ensure your target Bluetooth device (phone, headphones, speaker) is in pairing mode.
  • Move the M10 closer to the target device (within 10-20 meters).
  • Turn off and on Bluetooth on both devices, then try pairing again.
  • Clear previous Bluetooth pairings on your device if you're having trouble connecting to a new one.
• Poor FM transmission quality:
  • Try adjusting the FM frequency on the M10 to find a clear, unused channel on your FM radio.
  • Ensure there are no strong interfering signals nearby.
  • Adjust the placement of the M10 for better signal reception by the FM radio.
• USB U-Disk not playing:
  • Ensure the USB flash drive is formatted to FAT12/FAT16/FAT32/exFAT.
  • Verify that the audio files are in a supported format (MP3/APE/FLAC/WAV/WMA/ALAC/M4A).
  • Check if the USB drive is inserted correctly and is not damaged.

Specifications

User Tips

• For optimal FM transmission, experiment with different frequencies (76-108MHz) to find the clearest channel with minimal interference in your area.
• Keep the device fully charged for uninterrupted use, especially when using it on the go or for extended periods.
• When using the M10 in TX (Transmitter) mode, remember that it acts as a direct link to your Bluetooth headphones/speakers. It will not appear as a discoverable Bluetooth device on your source (e.g., TV or PC) but will connect directly to the receiving Bluetooth audio device.
• The 10-20 meter wireless range is an accessibility estimate; actual range may vary depending on environmental factors and obstacles.
