2

MIC

External MIC (Audio input)

When in audio communication, the pin is for MIC output. It should connect with the positive of the external MIC.

3

SPK

Audio output

The audio signal received by the radio will output by the pin after power amplifying, Power will be 500mW when driving 8 Ω speaker.

4

/MICPT

T

-0.7~5.7V

Transmission control(Audio)

The normal status of MICPTT is in high level. When it is in low level, it will enable the transmitter and send the audio signal. When data is prior to audio, it can’t enable the transmitter.
