[. . . ] Answer: Click out of the folder, and then back in to refresh the screen. Question: I clicked on the Cingular Connection Manager minimize button and noticed that the CCM icon was not in the taskbar. Where is the minimize icon and how do I bring forth the application to the desktop?Answer: The CCM minimizes into the Task-tray, which is represented by the "Cingular" trademark cross icon and not into the "Taskbar" (see the Cinguler logo illustration below). Depending on the strength of the GPRS signal, the trademark will reflect this with a degree of graduations. In other words, if the signal strength synchronizes to 3 bars (see the Task-tray illustration below), the Cingular trademark cross will show approximately half of trademark cross in the task tray. If the signal strength is one bar, the trademark cross will appear to show a bottom portion of the trademark cross. If the signal strength is at five bars, the entire Cingular trademark cross will be fully indicated. To bring forth the CCM to the desktop, click the Cingular trademark icon in the task-tray or right-click the Cingular trademark cross and select "Show".

Answer: The network speed indicator provides the capacity of the wireless device is 214. 4 Kbs but the actual speed depends on network throughput. To work around this, try to change the network settings to optimize the GPRS/EDGE value. This is done by accessing CCM --> Tools --> Settings. . . --> Advanced Networking, and then selecting "Optimized GPRS/EDGE value" option form the RWIN variables window. Question: I am experiencing dropped connections, slowness, and other difficulties while attempting to stream video over the Cingular GPRS connection. Answer: Bandwidth over the Cingular GPRS network is somewhat restricted as compared to wired or 802. 11x wireless connection types. Due to the demanding nature of streaming audio/video, it is not recommended that GPRS be used for either streaming video, or very large data downloads. Question: I am experiencing difficulty reconnecting to my web browser when switching from the Cingular GPRS network to a WLAN connection. Answer: The network behind the WLAN's Access Point may be set up to use a proxy server. If this is the case, proxy settings entered for Internet Explorer over WLAN may prevent IE from connecting over a GPRS link. To allow web browsing from either connection type: 1 Correctly configure IE proxy settings for use over the WLAN connection. Then, open the Cingular Connection Manager and rightclick the "GSM" tab. [. . . ] If a minimum distance of 15 cm (6 inches) is kept between the PC and the pacemaker, the risk of interference is limited. If you have any reason to suspect that interference is taking place, immediately turn off WAN feature. Contact your cardiologist for more information. For other medical devices, please consult the manufacture of the device.
