Troubleshooting

Check the questions and answers below for troubleshooting solutions for common device issues.
Check Here First
Question: Unable to connect via Wi-Fi (WLAN)
Answer 1: Check whether the mobile broadband device is properly connected to the computer or
other external device. Answer 2: If a WPS (Wi-Fi Protected Setup) connection fails, see the Wi-Fi device user guide. If
you're still unable to connect, set up the mobile broadband device Wi-Fi connection manually. See [xxxxx].
Answer 3: To connect a WPS Pin-specified Wi-Fi device, check whether the correct PIN has been used. For details, see [xxxxx].
Answer 4: If OPEN WEP is the security method being used, check whether the correct WEP key is entered. If the WEP key is unknown, see [xxxxx] to reset the WEP key and reconnect the device.
Answer 5: Check whether the correct WPA key is set. If the WPA key is unknown, see [xxxxx] to rset the mobile broadband device or see the WLAN Initialization Sticker to reset the WPA key, and then reconnect the device. WPA/WPA2 security may not be supported depending on the Wi-Fi device. See the Wi-Fi device user guide for information.
Question: Computer does not recognize the mobile broadband device.

FCC Regulations:
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 has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiated radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
-Reorient or relocate the receiving antenna.
-Increase the separation between the equipment and receiver.
-Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
-Consult the dealer or an experienced radio/TV technician for help.
Caution:
Changes or modifications not expressly approved by the party responsible for compliance could void the user‘s authority to operate the equipment.
FCC RF Exposure Information (SAR)
This device is designed and manufactured not to exceed the emission limits for exposure to radio frequency (RF) energy set by the Federal Communications Commission of the United States.
During SAR testing, this device is set to transmit at its highest certified power level in all tested frequency bands, and placed in positions that simulate RF exposure in usage near the body with the separation of 10 mm. Although the SAR is determined at the highest certified power level, the actual SAR level of the while operating can be well below the maximum value. This is because the device is designed to operate at multiple power levels so as to use only the power required to reach the network. In
general, the closer you are to a wireless base station antenna, the lower the power output.
The exposure standard for wireless employs a unit of measurement known as the Specific Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6W/kg.
The FCC has granted an Equipment Authorization for this model device with all reported SAR levels evaluated as in compliance with the FCC RF exposure guidelines. SAR information on this model device is on file with the FCC and can be found under the Display Grant section of on FCC ID: SRQ-MF975.
For this device, the highest reported SAR value for near the body is 1.38 W/kg.
While there may be differences between the SAR levels of various devices and at various positions, they all meet the government requirement.
SAR compliance for body operation is based on a separation distance of 10 mm between the unit and the human body. Carry this device, at least 10 mm away from your body to ensure RF exposure level compliant or lower to the reported level. To support body operation, choose the belt clips or holsters, which do not contain metallic components, to maintain a separation of 10 mm between this and your body.
