This section describes how to use each of these functions. 28 Technical Support: 800-283-5936

Audio Seettings displays the current audio settings and allows you to change them for the CHAT 160 currently connected to your PC). You can also create custom audio settings for a device (see Advanced Settings: Database later in this chapter for more information). The audio settings are as follows: • USB Auddio: These controls affect the audio settings of the CHAT 160 when it is connected via USB to your computer. Use the Mute buttons to mute either the microphone or speaker on the CHAT 160. Use the slid- ers to adjust the microphone level and speaker level. Speaker and microphone level adjustments made in the CHAT software will automatically change the speaker and microphone volume levels in Windows. • Line Audio: These controls affect the audio settings of the CHAT 160 when it is connected to devices through its I/O jack, such as handset telephones and video conferencing devices; they are grayed out and unavailable if only USB is connected. Use the input slider to adjust the level of the incoming audio to the speaker; use the output slider to adjust the level of the outgoing audio to the far end. • Speaker: These settings are only available when the VC Breakout Box is connected. The following options are available: • Normal: USB audio and line in audio from the VC Breakout Box are mixed through the CHAT 160 speaker. • Videoo Modde: Select this option to allow the audio from the far end of the video conference call to come through the TV speakers instead of the CHAT 160 speaker. Ensure that the CHAT 150 RCA con- nection cable (included with the CHAT 150 VC configuration) is properly connected (see CONNECT- ING CHAT 160 TO A VIDEO CONFERENCING DEVICE for detailed instructions). USB audio still comes through the CHAT 160 speaker in this mode. • External Sppeeakkeers: With this option selected, all audio (both USB and line in) is muted on the CHAT 160 and routed to the line out jack on the CHAT 150 VC Breakout Box, to which you can connect external speakers and/or an amplifier. In this mode, you are using the CHAT 160 as a microphone device only. Chapter 4: Using The Chat Application 229

with the audio coming through the I/O jack. For example, if this option is selected and you are talking to a colleague via Skype on your PC connected to your CHAT 160, and you also initiated a video conference call through the VC Breakout Box, all three parties would be joined together for a bridged call. The USB/Analog Mix setting is ignored while the Speaker option (see above) is set to Viideo Mode or Extternnal Speakers. • Line Echo Cancellation: Click this box to enable line echo cancellation. Line echo cancellation eliminates the echo caused when the CHAT 160 is connected to a telephone. On a telephone, audio is normally rout- ed from the mouthpiece to the earpiece so that you can hear your own voice while talking, which causes feedback on a speaker phone. Enabling line echo cancellation while not connected to a telephone may cause audio problems, so only use this option while connected to a telephone. Any settings changes that you make on this screen are instantaneously applied to the CHAT 160. In addition, you have the option to click on Save to Database to capture the current settings and save them as a custom device as described in the next section. Addvancedd Settings: Daatabassee Databassee displays the devices configured for the CHAT 160 and allows you to edit them. The CHAT 160 device database includes all of the audio settings for the devices pre-programmed by ClearOne (identified by the icon next to each device) and any custom audio settings you set up and wish to save for later use. The icon indicates that the device is in your My Devices list. To view the settings for a particular device, select the device and click the View button, or double-click the device name. The Viieew Dattabaase Reecord dialog appears. 30 Technical Support: 800-283-5936

To save custom audio settings for a device, perform the following procedure: 1. Click the New button. The AAdd Settiings to Database dialog appears with the settings of the device you had selected in the database view. 2. Adjust the audio settings or click Upload from CHAT to upload and display the CHAT 160’s current setings. 3. Click the Selectt 11sst drop-down box and select the desired device type. Or, you can type a custom name, if necessary. 4. Click the Selectt 22nnd drop-down box and select the desired manufacturer (or enter your own). Chapter 4: Using The Chat Application 331

6. If you do not wish to add this device to your list of My Devices, de-select the Include in My Devices check- box. The default is to include new devices in your existing list. 7. When all selections are made, click Ok. Click Cancel to discard your changes. 8. The custom device is added to the CHAT 160 device database and is now available through DDevicce SSetuup as an available device. (Note that in the device database, your custom device does not have the ClearOne icon next to it, differentiating it from a pre-programmed device.) To edit custom devices, click the Eddit button (appears in the place of the View button for custom devices) after selecting the custom device you wish to edit. The Edit Databassee Reccord appears. Adjust the audio settings, or click Uploaad from CHAT to upload the CHAT 160’s current audio settings. When you are finished editing, click OK. Then click YYes to save the device with the new audio settings or click No to return to the Eddit Dattabase RRecorrd dialog. To cancel your changes, click Cancell. To delete custom devices from the device database, click the Dellettee button after selecting the device you wish to delete. You can only delete custom devices; you cannot delete pre-programmed devices (devices with the ClearOne icon next to them). 32 Technical Support: 800-283-5936

Logg displays a list of actions taken by the CHAT 160, including a timestamp and a description of the action or even. To save the log to a text file, click the Save button. A standard Windows save dialog appears. Name the file and choose the directory in which you wish to save the file (the default directory is the CHAT 160 Log directory). Click Clleaar to clear all entries in the log window. Chapter 4: Using The Chat Application 333

• Follow all warnings and instructions in this manual. • Unplug all cables from the CHAT 160 before cleaning. • Unplug the power supply from the wall outlet (Phone/VC only) before cleaning. • Do not use liquid or aerosol cleaners. Use a damp cloth moistened with water to clean the outside of your CHAT 160 and power supply. TROUBLESHOOTING If you are having trouble with the audio from your CHAT 160, it might not be optimized (tuned) for the specific hardware device you are connected to. If you have not yet optimized the sound for this device, refer to the OPTIMIZING SOUND QUALITY section in Chapter 3. If you are still encountering problems, use the following procedure to troubleshoot the CHAT 160: 1. Activate the CHAT 160 software and verify the audio settings for the hardware device connected to your CHAT 160. If this does not solve the problem, then look more closely at your hardware device for the problem (refer to your hardware device’s User’s Manual or contact Technical Support for your hardware device). 2. Make sure all cables are properly and securely connected. Verify cable connections with the appro- priate illustration for your hardware device (see Chapter 2: Getting Started for more information). 3. If you’re connecting your CHAT 160 to a USB hub, be sure that the USB hub is connected to an external power source. 4. If you have another USB device such as a digital camera connected to your computer on the same bus as your CHAT 160, you may get a Windows error message “USB Controller Bandwidth Exceeded.” If this occurs, you need to move the other USB device to a separate USB bus. The CHAT 160 is a high-performance USB device and requires sufficient bandwidth in order to operate properly. If you are unable to resolve the problem using this procedure, please refer to the support pages on our web- site or contact ClearOne Technical Support: Phone: 1.800.283.5936 (USA) or 1.801.974.3760 Fax: 1.801.977.0087 E-mail: [email protected] Internet: www.clearone.com CHAPTER 5: MAINTENANCE 34 Technical Support: 800-283-5936

If a firmware update was interrupted (such as by a power loss or an accidental cable disconnection), the CHAT 160 might become unstable. The CHAT 160 boots in generic mode and the GGeeneric Mode screen appears. Use the following procedure to recover from interrupted firmware updates and unexpected programming errors: 1. Disconnect the USB 2.0 cable from the CHAT 160, hold down the Mutee button while reconnecting the CHAT 160, and follow the on-screen instructions. 2. The Generic Mode recovery screen appears . To perform the firmware update, click the Updaate Firmware button (see the Update Firmware & Database section in Chapter 3: Using The CHAT Application for detailed instructions). The messages “Initializing” and “Recovering” appear above the progress bar, followed by the typical messages that appear during a firmware update. The update then continues to completion. 3. The CHAT 160 also attempts to recover from a programming error by booting up in Generic (DFU) mode. In this case, follow the on-screen instructions. Chapter 5: Maintenance 335
