CHAPTER 5: MAINTENANCE

CARING FOR YOUR CHAT 50

•Follow all warnings and instructions marked on your Chat 50.

•Unplug the USB 2.0 cable from the Chat 50 before cleaning.

•Unplug the power supply from the wall outlet before cleaning.

•Do not use liquid or aerosol cleaners. Use a damp cloth moistened with water to clean the outside of your Chat 50 and power supply.

TROUBLESHOOTING POOR SOUND QUALITY

If you experience poor sound quality, check the following list for solutions to common issues.

•Ensure the Chat 50 is connected to your computer, start the Chat application, then verify, test, and adjust the audio settings as needed to obtain good sound quality. Or select an appropriate ClearOne pre- programmed device and click Apply to apply the settings to the Chat 50. If the issue remains unresolved, the third-party device or application may be responsible for the poor sound quality. Refer to the device or application documentation, or contact the manufacturer’s technical support for assistance.

•Verify that all cables are properly and securely connected. Refer to the appropriate connection diagrams in Chapter 2: Getting Started of this manual for more information.

•If your Chat 50 is connected to a USB hub, the USB hub must be connected to an external power source.

•If you have another USB device (such as a digital camera) connected to your computer on the same USB bus as your Chat 50, Windows may generate the error message “USB Controller Bandwidth Exceeded.” In this case, you must move the other USB device to a separate USB bus. The Chat 50 is a high- performance USB device that requires sufficient bandwidth to function properly.

•Some USB cameras that use audio drivers are automatically assigned by Windows as the default audio playback device (even though the camera doesn't have a speaker). In this case, disconnect all USB devices (including your Chat 50), reconnect the Chat 50 to the USB bus first, then reconnect the other USB devices. This allows Windows to properly select the Chat 50 as the default audio playback device.
