5.3 Using the External Audio System
At the right side of your computer, you will find the built-in audio ports. You
can connect Microphone jacks, earphone or powered speaker.
To connect to a audio jack:
1. Locate the audio port (Microphone, Headphone) that you want to use to
the target device.
2. Plug the jack into the port on the left side of the system.
+ If you use external speaker and experience the sound distortion or
feedback, please lower the volume. Some factors is caused by too close
locating the microphone and speaker from each other, moving away the
external audio option from the unit may also help.
