15 CHATAttach: Connecting Two CHAT Devices The CHATAttach makes it possible to connect two CHAT devices together for larger conference settings using the CHATAttach accessory kit. In order to use the CHATAttach accessory, the following criteria must be met: 1. Both CHAT devices must be the same model number - both CHAT 150, both CHAT 160 or both CHAT 170 devices - mixing CHAT models using CHATAttach is not currently possible. 2. Both CHAT devices must have identical firmware versions installed. The firmware must be CHATAttach compatible. To ensure this, download the latest version of the firmware from the Website and configure each device that will be connected to the CHATAttach accessory with the latest firmware. All older CHAT 150 devices require firmware updates in order to work with the CHATAttach accessory. 3. The CHAT device must be at least 5 apart for best performance. Use the following steps to connect the CHATAttach accessory. 1. Connect the two CHAT devices using the keyed CHATAttach cable. 2. Position the two CHAT 150 devices so they re at least 5 apart from each other. 3. Plug in the CHATAttach power supply. To prevent the power cable from inadvertantly becoming unplugged before, during or after meetings, it is recommended that the connector end of the cable be secured in some way. One approach is to knot the male-female connection to prevent this from occurring as shown above. A recommended professional approach to setting up a conference room utilizing the CHATAttach accessory is to drill holes near where the CHAT devices will be placed, route the cabling through the holes and secure them underneath the conference table as shown above. 4. Follow the instructions in the CHAT 150 User s Manual to setup the CHAT device with a PC. 12 Technical Support:

In this mode, you are using the CHAT 150 as a microphone device only. USB/Analog Mix: Click this box to mix the audio coming into the CHAT 150 through the USB connection 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 150, 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 Video Mode or External Speakers. Line Echo Cancellation: Click this box to enable line echo cancellation. Line echo cancellation eliminates the echo caused when the CHAT 150 is connected to a telephone. On a telephone, audio is normally routed from the mouthpiece to the earpiece so that you can hear your own voice while talking, which causes feedback on a speaker phone. WARNING: 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 150. 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.

30 CHAPTER 5: MAINTENANCE CARING FOR YOUR CHAT 150 Follow all warnings and instructions in this manual. Unplug all cables from the CHAT 150 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 150 and power supply. TROUBLESHOOTING If you are having trouble with the audio from your CHAT 150, 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 150: 1. Activate the CHAT 150 software and verify the audio settings for the hardware device connected to the CHAT 150. If this does not solve the problem, then look more closely at your hardware device for the problem (refer to the hardware device s User s Manual or contact Technical Support). 2. Make sure all cables are properly and securely connected. Verify cable connections with the appropriate illustration for your hardware device (see Chapter 2: Getting Started for more information). 3. If the CHAT 150 is connected through a USB hub, be sure that the USB hub is connected to an external power source. 4. If another USB device such as a digital camera is connected to the computer on the same bus as the CHAT 150, the Windows error message USB Controller Bandwidth Exceeded may be displayed. If this occurs, move the other USB device to a separate USB bus. The CHAT 150 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 the ClearOne Website or contact ClearOne Technical Support: Phone: (USA) Fax: tech.support@clearone.com Internet: Chapter 5: Maintenance 27

31 INTERRUPTED FIRMWARE UPDATE RECOVERY If firmware programming was interrupted (such as by a power loss or an accidental cable disconnection), the CHAT 150 might become unstable. The CHAT 150 software will boot into a generic mode and the Generic Mode screen will be displayed. To perform the firmware update, read and follow the instructions on the screen then click the Update Firmware button (see the Update Firmware & Database section in Chapter 4: 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. If the CHAT 150 attempts to recover from a programming error by booting up in the Generic (DFU) mode, a series of instruction windows will be displayed. Follow the on-screen instructions to resolve this issue. 28 Technical Support:
