One customer gave feedback that there were no sound in Xhorse ESL Emulator/ ELV Emulator. He turned EIS on many times but the emulators still won’t respond.
Here is the Answer:
Press the button inside using like a toothpick to switch sounds
Turn EIS on and ESL Emulator will sound if connected to power in vehicle or on bench
*There are no sounds in Mini Emulator, so just make sure data are written and emulators work well.
Done!
