Section 12 - Troubleshooting
Troubleshooting
1. Why am I unable to connect to a mobile service network?
The DWM-156 requires a SIM card registered with a compatible service network. For information about the services
that your SIM card provides access to, please contact your mobile service provider. The adapter will not connect to a
service network unless all relevant settings have been specied correctly. Please make sure that all connection prole
settings are accurate.
2. Why is the software asking for a PIN number?
For security, some SIM cards have a PIN number enabled. If the SIM was used in a previous device, the PIN will be
the same as it was before. If you did not set a PIN, please contact your mobile service provider.
3. Why are the connection speed and data transfer rates slow?
Please check the network signal strength. A low signal will result in poor performance.
4. Why am I unable to receive SMS messages?
This may happen with the SIM card memory is full. You may need to delete some messages to free up space.
5. Why is only part of the name saved when adding a new contact?
The SIM card can hold a maximum of 12 letters/characters for a contact name.
6. Why does the Windows connection icon display a speed of 115.2 Kbps?
115.2 Kbps is the data rate of the USB device, not the connection speed. Please refer to the connection statistics
shown within the Mobile Connection Manager for the actual connection speed.

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.
- 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.

RF Exposure Information (SAR)
This device meets the government’s requirements for exposure to radio waves.
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 U.S. Government.
The exposure standard for wireless mobile devices employs a unit of measurement known as the Specic Absorption Rate, or SAR.
The SAR limit set by the FCC is 1.6W/kg. *Tests for SAR are conducted using standard operating positions accepted by the FCC with
the device transmitting at its highest certied power level in all tested frequency bands. Although the SAR is determined at the highest
certied power level, the actual SAR level of the device 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 poser required to reach the network. In general, the closer you are
to a wireless base station antenna, the lower the power output.
The highest SAR value for the device as reported to the FCC when tested for use when worn on the body, as described in this user guide,
is 1.43 W/kg. (Body-worn measurements differ among device models, depending upon available accessories and FCC requirements.)
While there may be differences between the SAR levels of various devices and at various positions, they all meet the government
requirement.
The FCC has granted an Equipment Authorization for this device with all reported SAR levels evaluated as in compliance with the FCC RF
exposure guidelines. SAR information on this device is on le with the FCC and can be found under the Display Grant section of www.
fcc.gov/oet/ea/fccid/ after searching on FCC ID: KA2-WM1561.
For body worn operation, this device has been tested and meets the FCC RF exposure guidelines for use with an accessory that contains
no metal and the positions the handset a minimum of 0.5 cm from the body. Use of other accessories may not ensure compliance with
FCC RF exposure guidelines.
This USB dongle transmitter is approved for use in typical laptop computers. To comply with FCC RF exposure requirements, this USB
dongle should not be used in other devices or certain laptop and tablet computer congurations where the USB connectors on the host
computer are unable to provide or ensure the necessary operating congurations intended for the device and its users or bystanders to
satisfy RF exposure compliance requirements. This transmitter must not be collocated or operating in conjunction with any other antenna
or transmitter.
