Small red dongle (in PCMtuner package) would not heat; bigger green dongle (separate dongle) would heat and emit smells.
Remove an encrypted chip. (*please contact your seller and remove under the guidance of engineers from PCMtuner team)
Notes:
1)If PCMtuner dongle works well, heating is normal.
2)Even the encrypted chip burns off, dongle won’t lose connection with PC, since it is not necessary on the connection of main chip.
