This is Microphone only , speaker audio out from radio
KT-8900 can't use BT-89 Bluethooth Mic.
Because the old models are not ready to output voltage,
To the use of Bluetooth microphone so we will change this resistor to 10ohm, so as to obtain 8v voltage
How to modifty:
1) Remove the front pannel .
2) Change the resistor to 10 ohm
A . you have SMD 0401 10 ohm change it.
B. If not have SMD , you can add 1/4W 10 oHM , same result .
