3.3 Final Checks

Before powering on, double-check all connections and solder joints for any shorts or loose wires. Ensure the power switch is correctly installed and functional.

4. Operating Instructions

Your EIELE Multi-Function Speaker offers several playback options and control methods.

4.1 Powering On/Off

Locate the power switch on the rear of the unit. Flip the switch to the "ON" position to power on the speaker. The digital display will illuminate. To power off, flip the switch to the "OFF" position.

4.2 Playback Modes

The speaker supports multiple audio input modes:

• Bluetooth: Connect your phone or tablet wirelessly. The device name is typically "JQ BT".
• FM Radio: Use the control buttons or remote to scan and select FM radio stations. The power-off memory function will recall the last played station.
• AUX Input: Connect external audio devices (e.g., MP3 players, computers) using a 3.5mm audio cable.
• USB-Disk: Insert a USB flash drive with audio files. The speaker will automatically switch to USB playback mode.
• TF Card: Insert a TF (Micro SD) card with audio files. The speaker will automatically switch to TF card playback mode.

4.3 Controls

The speaker can be controlled using the onboard buttons or the included remote control.

Onboard Buttons:

• VOL-/PLAY/PAUSE/VOL+: Control volume, play/pause, and track navigation.
• MODE: Switch between different playback modes (Bluetooth, FM, AUX, USB, TF).
• SCAN: For FM radio, short press to auto-scan and store stations.

Remote Control:

The remote control provides extended functionality, including EQ settings and direct station tuning for FM radio.

Figure 4.2: Remote Control Functions. This diagram details the buttons on the remote control, including mode switching, volume adjustment, track navigation, EQ settings, and direct numeric input for FM radio frequencies.

4.4 Voice-Activated LED Level Indicator

The speaker features 12 colorful LED lights that react to audio input, providing a visual representation of the sound level. The sensitivity of these LEDs can be adjusted via a potentiometer on the circuit board (accessible after assembly).

5. Maintenance

• Cleaning: Use a soft, dry cloth to clean the acrylic case. Avoid abrasive cleaners or solvents that may damage the material.
• Storage: Store the speaker in a dry, cool place away from direct sunlight and extreme temperatures.
• Component Care: Handle the exposed circuit board and components with care to prevent damage.

6. Troubleshooting

If you encounter issues with your EIELE Multi-Function Speaker, refer to the following common problems and solutions:

• Device does not power on:
  • Check the power connection and ensure the USB power source is functional.
  • Verify the power switch is correctly installed and in the "ON" position.
  • Inspect all power-related solder joints for continuity and shorts.
• No sound output:
  • Ensure the volume is turned up on both the speaker and the connected audio source.
  • Check speaker wire connections to the circuit board.
  • Verify the correct playback mode (Bluetooth, FM, AUX, USB, TF) is selected.
  • If using AUX, ensure the cable is fully inserted and functional.
• Poor FM radio reception:
  • Extend the antenna fully.
  • Try repositioning the speaker to improve signal reception.
  • Perform an auto-scan for stations.
• LEDs not responding or behaving erratically:
  • Check the solder joints for all LEDs and the voice-activated circuit.
  • Adjust the sensitivity potentiometer for the LED level indicator.
• Project not completed or not working properly after soldering:

  If the project is not completed or does not work properly after soldering, please contact customer support immediately. Our goal is for each user to experience a sense of accomplishment when completing their project.
