NC-121VM

If your device is still not functioning after contacting the Andrea Support Team, you will be asked to submit your proof of purchase via email or fax, verifying that the product was purchased within 1 year. You will then be issued a return material authorization (RMA) number, with complete shipping instructions to return the device to our facility for evaluation. The customer is responsible for the return shipping. A traceable method such as UPS or Fed-X ground is recommended. If the device is found to be defective after evaluation at our facility, a new device will be shipped to you free of charge.

First, confirm that the microphone is not muted in the “Sound” settings located in your computer’s control panel. If not, reconnect the mic. Your computer should ask if the device you just plugged in is a line level or microphone level device. Choose MICROPHONE level. Next, open Sound Recorder and try to make a test recording: Start button -> All Programs -> Accessories -> Entertainment -> Sound Recorder. Click the red record button, and speak into the mic. The green line should start to move as you speak. If not, connect your mic to a different port on your PC and try to make a recording again. Repeat these steps until the green line moves when you make a recording.
NOTE: If you recently upgraded your operating system, you may need to update your sound card drivers by visiting the manufacturer’s web site.

The NC-121VM is not capable of converting a stereo or multichannel signal into mono. Mono, monophonic, or monaural, describes a recording where all the audio signals (typically a left and right signal) are mixed together and routed through a single audio channel. In the case of the NC-121VM, this must be done before the signal arrives at the headset’s single earphone, otherwise you will hear only the left channel side of the audio. Windows XP has the ability to convert a stereo playback signal to mono, but this feature was dropped in later versions of Windows.

Yes. The NC-121VM simply plugs into your computer’s sound card.

Our NC-181VM USB, NC-185VM USB, EDU-455 USB and EDU-255 USB are compatible with most dictate programs for the Mac.

Unfortunately, there is no way to disable the mute button.

VM stands for Volume/Mute, as the headset has an in-line volume control for the headset speakers, and a mute switch for the microphone. VM USB indicates that the Andrea USB-SA External Digital Sound Card is in-line, or built into the cable, as well as a digital in-line Volume/Mute control. Most voice recognition programs recommend using a USB sound card for increased performance.

Your device will require either our USB-SA, EDU-USB External Digital Sound Cards, or our C-100 mobile adapter. We also offer the following units, that are wired for single port use.

• NC-181M
• NC-185M
• EDU-255M
• EDU-455M

No software is required. Simply plug the headset into your PC microphone and headphone ports.

The headset needs only to be calibrated within Dragon. Simply run the volume calibration and accuracy check after adding the device to your user profile. It would be best to contact Nuance for support with their software regarding the location of these features.

The microphone ground and the speaker are independent. They are not linked.

With the headband fully extended (from the center of the headset speaker to the bottom of the pad that rests on the opposite side of the head), the length is approximately 17″.
