Update voice files

Method 1: Prepare the necessary tools, such as computer, card reader, micro SD card(capacity less than 8GB is better). Format micro SD card on the computer as a FAT32 file system, then put the MP3 audio into micro SD card. After finishing copying MP3 file, insert micro SD card to the slot, long press “B” button (the right one), and turn on the power switch. At this time indicator light is on for a long time. When the red light flashes, release the button, copying the voice from micro SD card to FLASH until the light is off, that is, the voice update is finished.

Method 2: Insert the TF card into the card slot, connect the computer with the micro USB data cable, recognize the mobile drive letter, format the mobile drive letter as FAT32 format, and then copy the prepared MP3 voice to the mobile drive letter, disconnect the data cable, you can turn on the unit, it will play the TF content first, and finally press the A/B button shortly to listen to it.

Note:

1. The capacity of audio file storage should be not more than that of internal FLASH (4MB).
2. After finishing copying, sometimes play a section of voice. When finishing the voice play, it can trigger and play again.
3. After finishing copying, sometimes there maybe invalid body induction, false dead lock, back to normal working state with power on again.

FAQ

Question 1: Can this product play WAV audio? If not, what’s the solution?

Answer: This product only supports MP3 audio, no support to WAV audio. But there are the following solutions to convert to MP3 format. Solution 1: Install audio player software with the function of MP3 encoding and decoding, converting WAV audio format into MP3 files. Solution 2: Search online directly and download MP3 audio.

Question 2: During use, this product is found that it interrupts when playing half, then continues to play and the cycle continues. What happened?

Answer: This is caused by unstable power, because battery power is low or voltage is unstable. Please replace the battery.

Question 3: After power on, in a period time there is no response or reaction is not sensitive, such as delay phenomenon. What happened?

Answer: After power on, there will be 5-20 seconds of power initialization. During this period, it is normal to have no response or slow reaction. After this time it will work normally.

Question 4: When updating audio, sometimes it needs to wait for a long time. What is the problem?

Answer: This may be because in the last time, it hasn't finished updating before the power off or because the external power supply is not stable, causing the FLASH file error or damaged. Thus, when updating audio again with power on, it will repair the FLASH file, so the time is a little longer.
