Adjusting Microphone and Speaker Volume
Your unit is equipped with a built-in speaker, but you can connect an
external speaker if you prefer. You can also connect a microphone or a
headset to your unit.
To fit your work environment, you may adjust the microphone as well as
the speaker (built-in or external) or headphones volume. Values are kept in
memory even when you turn the unit off.
Note: When you use a headset, ensure that both the microphone and
headphones jacks are connected properly to the appropriate audio ports.
The control of the volume for the microphone and the headphones of the
headset are independent of each other.
To adjust microphone volume:
1. Ensure that your microphone (or microphone jack if you are using a
headset) is connected to the audio in port located on the right panel of
the unit.
2. From the main window, tap the System Settings button.
