5. Setup

5.1. Initial Charging

1. Connect the provided USB cable to the module's USB charging interface.
2. Plug the other end of the USB cable into a DC 5V power source (e.g., computer USB port, USB wall adapter).
3. The charger indicator (red LED) will be ON during charging.
4. The red LED will turn OFF once the module is fully charged. Charging typically takes 5 to 15 minutes.

5.2. Mounting the Magnetic Switch

The magnetic switch is crucial for triggering playback. Ensure proper placement for desired functionality.

This image explains the optimal mounting position for the magnet above the magnetic switch component, noting that the magnet is effective within 1cm and works with materials like paper and glass, but not metal.

• The magnet should be mounted above the component of the magnetic switch.
• The effective distance between the magnet and the magnetic switch is less than 1 cm.
• The magnet is effective for materials like paper, glass, etc., but not metal.
• The magnet is typically pre-attached to the speaker before shipping.

6. Operating Instructions

6.1. Power On/Off

Locate the independent power switch on the module. Slide it to the "ON" position to power on the device. Slide it to "OFF" to power off.

6.2. Magnetic Control Playback

The module supports two types of magnetic playback triggers: "Magnetic Approaching" or "Magnetic Leaving". Your module is pre-configured with one of these modes and cannot be switched by the user.

This image shows how to power on the module using the ON/OFF switch and illustrates both 'Magnetic Approaching' and 'Magnetic Leaving' methods to trigger music playback.

• Magnetic Approaching: Move the magnet close to the magnetic switch to start playing music. Remove the magnet to stop playing.
• Magnetic Leaving: Move the magnet away from the magnetic switch to start playing music. Move the magnet close to the magnetic switch to stop playing.

This image demonstrates the 'Magnetic Leaving' play mode, where moving the magnet away from the magnetic switch initiates music playback.

6.3. Adjusting Play Volume

The play volume can be adjusted using the potentiometer on the module. Use the provided screwdriver to rotate the potentiometer.

• Rotate clockwise to decrease volume.
• Rotate counter-clockwise to increase volume.

6.4. Changing Play Modes

The module supports three different play modes, which can be selected by changing the switch status on the PCB. Refer to the diagram below for specific settings.

This table details the three play modes (Loop Playback, Non-loop Playback, Next Song) for both 'Magnetic Approaching' and 'Magnetic Leaving' trigger types, along with their descriptions.

• Loop Playback: When triggered, music plays continuously in a loop. Removing the magnet stops playback.
• Non-loop Playback: When triggered, music plays once in order. Removing the magnet stops playback.
• Next Song: When triggered, the next song in the sequence plays. Removing the magnet stops playback.

7. File Management (Uploading/Deleting MP3s)

The DONGKER module functions like a USB drive, allowing you to easily add or remove MP3 audio files from a computer.

1. Ensure the module is powered OFF.
2. Connect the module to your computer using the provided USB cable.
3. The module will appear as an external drive (e.g., "USB Drive (D:)" on Windows, "NO NAME" on Mac).
4. Delete Existing Files: Open the drive. Delete any pre-loaded or unwanted MP3 files. DO NOT FORMAT THE DRIVE. For Mac users, ensure you empty the trash after deleting files to free up space.
5. Add New Files: Copy and paste your desired MP3 audio files into the module's drive.
6. Important: Only MP3 files are supported. Non-MP3 files will not play correctly and may cause playback issues.
7. Once files are transferred, safely eject the drive from your computer before disconnecting the USB cable.

7.1. Sound Chip Capacity

• The unit has an 8 MB capacity.
• This translates to approximately 120 seconds of total recording time for MP3 files.
• There is no limitation on the number of MP3 files that can be uploaded at once, provided the total capacity does not exceed 8 MB.

7.2. Converting and Adjusting MP3 Files

• Upload ONLY MP3 files. The unit will NOT play other file formats.
• You can convert non-MP3 files to MP3 format using dedicated free websites.
• Adjusting the sound volume level of your MP3 files will ensure consistent playback sound volume levels from the module. You can adjust the sound volume of your MP3 files using dedicated free websites.

8. Applications

The DONGKER Voice Record Module is versatile and can be integrated into various projects:

• DIY Gifts
• Greeting Cards
• Toys
• Photo Albums
• Holiday Crafts
• Other creative projects requiring custom voice or music playback.

This image showcases various applications for the voice record module, such as DIY gifts, greeting cards, toys, and photo albums.

9. Troubleshooting

• Module not appearing as external drive on PC/Mac:
  • Ensure the module's power switch is in the "ON" position when connecting to a computer.
  • Double-check that the USB cable connections are firm and stable on both the module and the computer.
  • Only use the provided USB cable. Some cables are only capable of charging but not transferring data.
  • If the issue persists, try connecting the module to a different USB port or another computer (PC or Mac) to rule out computer-specific issues.
• No sound or low volume during playback:
  • Ensure the module is powered ON.
  • Check the volume adjustment potentiometer and rotate it counter-clockwise to increase the volume.
  • Verify that the MP3 files uploaded are not corrupted or have very low original volume. Adjust the volume of your MP3 files using audio editing software if necessary.
• Module not playing after uploading files:
  • Ensure all uploaded files are in MP3 format. Non-MP3 files will not play.
  • Verify the play mode setting (Loop, Non-loop, Next Song) is correctly configured according to your preference.
  • Ensure the magnetic trigger is activated correctly based on your module's pre-selected mode (Magnetic Approaching or Magnetic Leaving).
• Green light comes on when plugged into PC/Mac but no playback:
  • This is normal. The unit will not play audio while plugged into a PC or Mac for file management. Disconnect the module to enable playback.
• Cannot record directly by speaking into the module:
  • This module does not support direct voice recording via a built-in microphone. To record your own voice, record it into your device (e.g., smartphone, computer) first, then transfer it as an MP3 file into the sound module via USB.

10. Safety Information

• Keep the module away from water and moisture.
• Avoid exposing the module to extreme temperatures.
• Do not attempt to disassemble or modify the module, as this may void the warranty and cause damage.
• Keep out of reach of small children due to small parts.
• Use only the specified DC 5V charging voltage.
