Microphone Level Settings for Windows XP: Skype and Google automatically adjust these volume levels for you during your conversation. If you are using Skype or Google you DO NOT have to manually adjust your computer microphone level. For other internet calling services, you may need to adjust your computer microphone level in order for the person on the other end to hear you perfectly. Below is a description of how to adjust your computer microphone for Windows XP systems. However, this setting adjustment should also be available in other versions of Windows. Make sure your USB adapter is connecting your headset to your computer. Start > Control Panel > Choose Sound and Audio Devices > Click the 'Audio' tab > Under 'Sound Recording' click the 'volume' button> If a 'Microphone' option is available adjust it how you see fit. If a 'Microphone' option is NOT available (likely): Choose Options > Properties > Check Microphone> Adjust accordingly Internet Headset Online User Guides Page 12 of 13
