irregular after connecting the bluetooth device (like no sound, jammed), you can try to turn off the emitter device and turn on again.
③ Because there are differences in the schemes and agreements used for different bluetooth devices, it may cause the
failure or the phenomenon of no sound when using by connecting “One drives two” under the transmit mode, you can try to
disconnect one bluetooth device.
Fault diagnosis:
When meeting the following problems, you can try to solve by the following methods, but if there are still problems after
handling, Please connect with the dealer,do not open the machine and repair by yourself to avoid the unnecessary troubles.
If the adapter can’t work normally?
1)Please insert the charger and connect, inspect if the battery has power or not.
2)Please turn on after the power supply is off, inspect if it can wake up for workor not.
3)If you can’t search this device on the phone, please inspect if the device is on the matching and connecting status
under RX mode, whether “RX” indicator turns on or not, you can refer to the instruction in the above functional operation
under RX mode.
4) If the bluetooth device (bluetooth earphone or acoustics) can’t be searched under TX mode, please inspect if the device
is under TX mode for searching the bluetooth device, whether “TX” indicator turns on or not, you can refer to the instruction
of connecting the bluetooth device in the above functional operation under TX mode.
5) The device working mode and status can be judged according to the LED working indicator in front of the device.
6) If there is no sound after connecting SPDIF, please inspect if there is the audio cable inserted in AUX audio port on
the device or not.
7) If the sound is interrupted or jammed during the use, you can try to turn off this emitter and turn on again. Please don’t
place it on the metal objects, place it in front of TV without any shelters. When playing by using the high bit rate audio
source input (like blue ray DVD audio source), it may cause the sound interrupted / jammed, this product supports
24bit/48KHZ transmission.
8) Because the chip scheme and the transmission agreement of all kinds of the bluetooth receiver are different, there
may exist the failure of matching, we are striving for optimizing it.
