What to do if a PC in the LAN cannot access the Internet? If the power indicator is off, you need to check whether the power adapter is normally connected. If the signal strength indicator is off, you need to check whether the area is covered by the network. 22 If the area is covered by the network, you need to check whether the network mode is correct. For information about network mode, see "Mobile Network Settings". If the indicator of the Ethernet interfaces blinks, the corresponding Ethernet interface is normally connected. If the indicator is off, you need to check and ensure that the related Ethernet connection is normal. You must configure the correct PPP user name and PPP password when you access the Internet through the device. Check whether they If the DHCP service is disabled and the PC obtains the IP address dynamically, the PC also cannot access the Internet. You can change the mode to manually assign an IP address. See "Configuring the Network Connection". Check whether the driver of the network adapter is correctly installed. If the preceding methods cannot solve the problem, please consult you service provider. What to do if a PC in the WLAN cannot access the WLAN? If interferences or shields near the device exist, you can adjust the position of the device. When the signal strength is strong, you can move to the next step. Check and record the following data on the network adapter of your PC: SSID, WEP type, and key. Make sure that the two devices work on the same channel. For details, see "Selecting a WLAN Channel". Check and record the following data on the device: SSID, WEP type, and key. Make sure that the MAC address of one device is in the peer MAC address list of the other device. For details, see "WLAN Bridge". Compare the recorded data, the SSID on the network adapter should be ANY or be the same as that on the device. The WEP type and key on the network adapter and device should be the same. Otherwise, you need to change the data on the network adapter. What to do if I forgot the IP address of the LAN interface? If you forgot the IP address of the LAN interface, you can enter http://e.home and log in to the management page when the PC obtains the IP address automatically. What to do if bridging between two devices is unsuccessful? When the signal strength is normal, what to do if the downloading rate is low? Troubleshooting In this case, you need to set the value in the registry as follows: Choose Start > Run. Enter regedit in the Open text box and then click OK. Select parameters in the following directory: \HKEY_LOCAL_MACHINE\SYSTEM\CurrentC ontrolSet\Services\Tcpip. Choose Edit > New > DWORD Value. Rename New Value #1 to TcpWindowSize. 23 24 Right-click TcpWindowSize and then select Modify. Select Decimal and enter 65535 in the Value data text box, and then click OK. For the DWORD Value of DefaultRcvWindow, do the same operations as that of TcpWindowSize. 6 Safety Information Read the safety information carefully to ensure the correct and safe use of your wireless device.

Therefore, the connection cannot be guaranteed in all conditions. In an emergency, you should not rely solely on the wireless device for essential communications. Specific Absorption Rate (SAR) Your wireless device is a radio transmitter and receiver. It is designed not to exceed the limits for exposure to radio waves recommended by international guidelines. 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 guidelines use a unit of measurement known as the Specific Absorption Rate, or SAR. The SAR limit for wireless devices is 2.0 W/kg and the highest SAR value for this device when tested complied with this limit. Body Worn Operation Important safety information regarding radiofrequency radiation (RF) exposure. To ensure compliance with RF exposure guidelines the device must be used with a minimum of 1.5 cm separation from the body. Failure to observe these instructions could result in your RF exposure exceeding the relevant guideline limits. Safety Information (such as alcohol and benzene), chemical detergent, or powder to clean it. • Do not leave your wireless device and accessories in a place with a considerably low or high temperature. • Use only accessories of the wireless device approved by the manufacture. Contact the authorized service center for any abnormity of the wireless device or accessories. • Do not dismantle the wireless device or accessories. Otherwise, the wireless device and accessories are not covered by the warranty. Regulatory Information The following approvals and notices apply in specific regions as noted. CE Approval (European Union) The wireless device is approved to be used in the member states of the EU. The wireless device is in compliance with the essential requirements and other 27 Regulatory Information relevant provisions of the Radio and Telecommunications Terminal Equipment Directive 1999/5/EC (R&TTE Directive). CE Statement: The antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20cm from all persons. Federal Communications Commission Notice (United States): Before a wireless device model is available for sale to the public, it must be tested and certified to the FCC that it does not exceed the limit established by the government-adopted requirement for safe exposure. The SAR limit adopted by the USA and Canada is 1.6 watts/kilogram (W/kg) averaged over one gram of tissue. The highest SAR value reported to the FCC for this device type was compliant with this limit. FCC Statement This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. * This device should be installed and operated with a minimum distance of 20 cm between the radiator and your body when using it via USB cable. 28 This equipment has been tested and found to comply with the limits for a Class B digital Device, pursuant to Part 15 of the FCC rules Changes or modifications made to this equipment not expressly approved by (manufacturer name) may void the FCC authorization to operate this equipment. 7 Abbreviations 3G The Third Generation WLAN AP Access Point WCDMA Wideband CDMA APN Access Point Name WI-FI Wireless Fidelity CDMA Code Division Multiple Access DHCP Dynamic Host Configuration Protocol DNS Domain Name Server EDGE Enhanced Data rates for GSM Evolution GSM Global System for Mobile communications GPRS General Packet Radio Service HSPA High Speed Packet Access HSDPA High Speed Downlink Packet Access HSUPA High Speed Uplink Packet Access IP Internet Protocol LAN Local Area Network LED Light Emitting Diode NAT Network Address Translation POTS Plain Old Telephone Service UMTS Universal Mobile Telecommunications System WAN Wide Area Network Wireless Local Area Network 29
