The S31 Portable Wireless Speaker is a versatile audio device designed for a range of listening experiences, offering both convenience and robust performance.

Function Description:

The S31 speaker primarily functions as a wireless audio playback device, connecting to other devices via Bluetooth. It supports various audio sources, including U disk, TF card, and AUX input, providing flexibility in how users can play their music. A notable feature is its FM radio capability, allowing users to tune into local broadcasts. The speaker also incorporates a built-in microphone, enabling hands-free calling for added convenience. For an enhanced audio experience, the S31 supports TWS (True Wireless Stereo) interconnection, allowing two S31 speakers to be paired and play music synchronously, creating a stereo soundstage. Beyond its audio functions, the speaker includes a unique "reverse charging" technology, effectively turning it into a portable power bank to charge other low-battery devices. It also features dynamic music light effects that can sync with the rhythm of the music, adding a visual dimension to the listening experience.

Important Technical Specifications:

• Connectivity: Wireless (Bluetooth), AUX input, U disk, TF card.
• Waterproof Rating: IPX7, indicating it can withstand immersion in water up to 1 meter for 30 minutes.
• Battery: Features reverse charging technology, allowing it to act as a power bank.
• Audio Output: High-fidelity speakers.
• Microphone: Built-in for hands-free calling.
• Special Features: Music light effects (syncs with music, slow pace, quick dance, no light), TWS interconnection, FM radio, memory function (remembers settings).
• Default Startup Volume: 70%.

Usage Features:

• Power On/Off & Function Switch: A single button is used for both powering the device on/off (long press) and switching between functions (short press). The function switching sequence is Wireless mode -> AUX mode -> FM mode. U-disk and TF card modes are activated automatically when the respective media is inserted.
• Volume Control: Dedicated buttons for increasing (+) and decreasing (-) volume. Long pressing these buttons adjusts the volume, while short pressing navigates to the next or previous track/FM channel.
• Playback Control & Calls: A dedicated play/pause button (►) allows for short presses to pause/play music, auto-search in FM mode, or answer/hang up phone calls. Long pressing this button switches music light effects or rejects incoming calls.
• TWS Interconnection: To activate TWS, double-click the play/pause button on either of two S31 speakers when both are on and within 10m. They will connect automatically if previously paired. Double-clicking the play/pause button again on either speaker will disconnect them.
• Reverse Charging: To use the reverse charging feature, turn on the speaker and connect the device to be charged to the speaker's USB-A port using a USB cable. The speaker's micro-USB port is for charging the speaker itself.
• Voice Prompts: The speaker provides voice prompts for power on/off, low battery (with an automatic shutdown 30 seconds after the second low battery prompt), and maximum volume. There is no voice prompt for minimum volume.
• Indicator Light: At the charging port, a white light flashes quickly during wireless search and stays on during wireless pairing. A red light indicates charging, which turns off when charging is complete.

Maintenance Features:

• Troubleshooting - Wireless Connection: If connection fails, check if the speaker is connected to another device, disconnect if necessary, and retry. Restarting the speaker is also an option.
• Troubleshooting - Auto Power Off: The speaker automatically turns off due to low battery (protection feature) or after 3 hours of inactivity to conserve power.
• Troubleshooting - Music Playback: If music fails to play, ensure music files are stored in the root directory of the removable device.
• Troubleshooting - No Sound (Computer): If connected to a computer with no sound, check the computer's audio output port for correct connection.
• Troubleshooting - No FM Signals: Weak signals can be improved by using the attached USB cable as an antenna. Insert the cable into the speaker and use the AUX end to search for signals.
• Precautions:
  • Keep out of reach of children.
  • Do not disassemble the speaker.
  • Avoid striking the speakers.
  • Keep away from fire, water, and extreme temperatures (too high or too low).
  • Do not overcharge the speaker to prevent battery damage.
