1. Turn on the audio power, short press the "Input Select" button to switch to Bluetooth mode

2. Turn on the Bluetooth of the mobile phone, find the device with the relevant name of Bede or Wanlida in the Bluetooth list (the Bluetooth name of Bede audio generally starts with BD, and the Bluetooth name of Wanlida audio generally starts with M+), and click to pair

after finding it 3. If the pairing code prompt (PIN code) pops up, enter 1688

1. Check whether the power switch is turned on and switched to Bluetooth mode

2. Check whether the paired Bluetooth name is correct

3. Check whether the speaker has been connected to other devices, if Bluetooth is occupied, it needs to be disconnected from the old device and reconnected

4. Whether the distance between the mobile phone is too far, the effective reception range of Bluetooth is generally 5-10 meters, and the mobile phone and the speaker should be close to each other without other obstructions

5. Restart the speaker, or try to replace the mobile phone connection

1. Check whether the Bluetooth of the mobile phone is paired successfully

2. Check whether the mobile phone and the speaker are muted and adjust to the appropriate volume

3. Restart the mobile phone and the speaker, if it still doesn't work, you can try to replace the connection of other mobile phones

1. Non-video machine: Download MP3 or WMA format audio files to the USB flash drive, it is recommended to delete unnecessary files and directories to avoid multiple layers of files affecting data reading, then turn on the speaker, insert the USB disk into the USB interface, press the "Input Selection" button to switch to the audio input mode, the audio will automatically read the files in the USB flash drive and play it. 2. Video all-in-one machine/song orderer: Insert the USB disk into the USB interface, click the "USB disk" option on the screen, Then select audio or video to play the corresponding file, support wav, mp3, ape, m4a format audio files and mp4, mov, mpg, mpeg, mkv format video files, audio/video files are recommended to be put in the song folder in the root directory of the USB flash drive

1. Check the audio format and confirm that the files in the USB flash drive are MP3 and WMA formats supported by the audio, and the unsupported formats will not be recognized

2. Format the USB flash drive to FAT32 format, and the capacity of the USB flash drive is recommended to not exceed 64G

3. Unplug the USB flash drive and reinsert it, check whether the USB flash port is in good contact

4. Check whether the USB flash drive is damaged, and the USB flash drive can be replaced for testing

Common frequency countering methods:

1. First, turn on the speaker and microphone, press and hold the "↑" button facing the microphone upwards for 3-5 seconds, and let go after the screen appears (SEL) character flashes into the setting state;

2. Then short press the "↑" or "↓" button to change the frequency point, commonly used frequency points A01, B51

3. After selecting the frequency point, immediately face the microphone display to the audio display (face to face) for 10-15 seconds to complete the frequency matching.

(If the fixed frequency microphone does not need to be manually frequency matched, just install the battery and turn it on).

1. Check whether the microphone battery is charged, replace the battery or charge it if it is dead

2. Check whether the microphone volume is turned up,

3. Microphone frequency matching, if there is a lock screen, long press the switch and up button, when the ID word appears, let go of the defrequency and then pair the frequency

. Force frequency matching, turn on the microphone and press and hold the "↑" button, hold it without letting go, turn off the speaker after displaying "SEL", wait for the microphone to show two levers "--" and then turn on the speaker and let go to complete the frequency matching

5. If there is signal interference nearby, the frequency adjustment needs to be staggered

. Test a wired microphone to eliminate the problem of failure of the microphone and the microphone plate itself

1. Adjust the microphone frequency point, open the microphone and press and hold the up button until the SEL character appears, then adjust the frequency point to avoid the original serial frequency point, and then bring the microphone close to the speaker and wait for the frequency matching to be completed

2. Press the power button and the up button at the same time to identify the microphone ID to avoid subsequent mistakenly touching the frequency change or cross-frequency again

3. The fixed frequency microphone cannot be modulated, if there are other microphones nearby that use the same frequency point, you can adjust the distance or change the venue

audio remote control is divided into ordinary models, voice models and Bluetooth models, and there are differences in the use of different types of connections, the specific methods are as follows:

1. Ordinary remote control: install the battery, turn on the audio power and press the button directly to use, no need to manually pair

2. Voice remote control: plug the USB receiver of the remote control into the USB interface of the speaker, and then install the battery on the remote control, and long press the voice button on the remote control to start the voice control function, and you can order songs by voice

3. Bluetooth remote control: turn on the speaker and select the Bluetooth mode, after installing the battery, let the remote control get as close to the speaker to be connected as possible, short press or long press the green pairing button in the upper right corner, when the indicator light stops flashing, it means that it has been successfully paired and can be used normally

1. Check the battery level, replace it with a new battery for testing, and ensure that the positive and negative poles are in the correct direction when installing the battery

2. When using the remote control, you need to align the signal receiving window on the front of the speaker, remove the occlusion, and control the distance within 6 meters

3. When pairing the Bluetooth remote control, please keep the remote control within 1 meter of the speaker, and it can be used normally within 15 meters of the speaker after successful pairing (if the same speaker is paired with the mobile phone remote control APP, The mobile app must be disconnected to pair the remote control).

1. Check whether the power switch is turned on

2. Check whether the audio source signal output is normal, such as connecting to the mobile phone Bluetooth to confirm that the audio and the speaker are successfully paired

3. Check whether the volume of the audio or sound source is adjusted to the minimum

4. Replace the audio source equipment for testing

5. Disconnect the audio power supply and turn it on again and try again

1. Check whether the audio power is sufficient, fully charge or plug in the power supply again 2

. Plug in the charger to check whether there is a charging indication, check whether the battery wire is in poor contact

3. Check whether the power button is stuck or loose, if the power switch is damaged and needs to be replaced .
