Audio Options
The NEC Versa comes equipped with built-in audio ports that let you record and play
sound.
Connect audio jacks, like a microphone, headphones, or external speakers to the audio
ports as follows.
1. Locate the audio port that you want to use.
2. Plug the jack into the appropriate port on the front of the NEC Versa.
Audio ports
A – Microphone C – Headphones
B – Line In D – Volume Control
Note If you are using external speakers or an external microphone and experience
sound distortion or feedback, lower the volume.
Some feedback is caused by having the microphone and speakers too close to each
other, so moving the external audio option away from the unit may also help.
Port Replicator
Use the following steps to connect the NEC Versa VXi to the Port Replicator.
1. Remove any devices connected to the back of the NEC Versa.
