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. (The simplest way is to use "TT Player" to convert the format. For the specific operation, please use "Baidu", such as "TT Player format conversion".)
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 because lithium battery power is low or voltage is unstable. It will work just by hanging or charging the lithium 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 10-20 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 moment. What is the problem?
Answer: This may be because in the last update, it hasn't finished updating before the power is off or because the external power supply is not stable, causing the FLASH file inside the host error or damage. Thus, when updating audio again with power on, the main engine will repair the FLASH file, so the time is a little long.
Qustion 5: why is the triggering voice on the set direction contrary to the description in the instruction manual?
Answer: This may be due to the voltage instability of the power or other reasons, causing the loss of factory direction correction mark bit saved in the host. You just press both button A and B before power on, then the indicator light flashes 2 times, at this time, loosen button A and button B. By this way you can correct the triggering direction voice.
