Computers in the Yamada Language Labs use USB headsets with built-in microphones and volume control.

3. Make sure the headphones are not muted. On the headset's volume control (attached to the cord), the red light indicates that it is muted. The red light must be off for the headsets to play or record sound:

Tips

• When using the headsets to record your voice, such as on Voiceboard, it is a good idea to test it first to make sure the microphone is working. That way, if it is not working you do not need to repeat your entire recording. If it is not working, go through the steps outlined above and keep testing until you get a good recording.
