[. . . ] The wireless device described in this guide is approved for use on the UMTS 900, 1700/2100, and 2100 MHz networks, and GSM 850, 900, 1800, and 1900 MHz networks . Your device supports several connectivity methods and like computers may be exposed to viruses and other harmful content. exercise caution with messages , connectivity requests , browsing , and downloads. Only install and use services and software from trustworthy sources that offer adequate security and protection, such as applications that are Symbian Signed or have passed the Java VerifiedTM testing. [. . . ] When the device is locked, only connections to authorized devices are possible. When you open the application for the first time, you are asked to define a name for your device. My phone's visibility -- To allow your device to be found by other devices with Bluetooth wireless technology, select Shown to all. To set a time period after which the visibility is set from shown to hidden, select Define period. My phone's name -- Edit the name shown to other devices with Bluetooth wireless technology. Remote SIM mode -- Enable or disable another device, such as a compatible car kit accessory, to use the SIM card in your device to connect to the network. For example, if you are connected to a compatible headset, you can also transfer files to another compatible device at the same time. Devices with Bluetooth wireless technology that are within range are displayed. Device icons are as follows: phone Select the device with which you want to connect. If the other device requires pairing before data can be transmitted, a tone sounds, and you are asked to enter a passcode. Tip: When searching for devices, some devices may show only the unique address (device address). Your device comes with various applications, such as TeleNav Navigator and Maps. If you have questions about billing or about using this service, contact T-Mobile. With Maps, you can see your current location on the map, browse maps of different cities and countries, and search for addresses and places of interest.

The content may be inaccurate and incomplete to some extent and is subject to availability. [. . . ] These guidelines were developed by the independent scientific organization ICNIRP and include safety margins designed to assure the protection of all persons, regardless of age and health. The exposure guidelines for mobile devices employ a unit of measurement known as the Specific Absorption Rate or SAR. Tests for SAR are conducted using standard operating positions with the device transmitting at its highest certified power level in all tested frequency bands. The actual SAR level of an operating device can be below the maximum value because the device is designed to use only the power required to reach the network. [. . . ]
