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.
Modifications not expressly approved by the manufacturer could void the user’s authority to operate
the equipment. This transmitter must not be co-located or operated in conjunction with any other
antenna or transmitter.
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.
Exposure to Radio Frequency (RF) signals
THIS MODEL DEVICE MEETS THE GOVERNMENT’S REQUIREMENTS FOR EXPOSURE TO
RADIO WAVES.
Your wireless device is a radio transmitter and receiver. It 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 and Industry Canada of the Canadian Government. These limits
are part of comprehensive guidelines and establish permitted levels of RF energy for the general
population. The guidelines are based on standards that were developed by independent scientific
organizations through periodic and thorough evaluation of scientific studies. The standards include a
substantial safety margin designed to assure the safety of all persons, regardless of age and health.
The exposure standard for wireless mobile phones employs a unit of measurement known as the
Specific Absorption Rate, or SAR. Tests for SAR are conducted with the phone transmitting at its
highest certified power level in all tested frequency bands. Although the SAR is determined at the
highest certified power level, the actual SAR level of the phone while operating can be well below the
maximum value. This is because the phone 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. Before a phone 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 tests are performed in positions and locations (e.g., at the
ear and worn on the body) as required by the FCC for each model.
The available scientific evidence does not show that any health problems are associated with using
low power wireless devices. There is no proof, however, that these low power wireless devices are
absolutely safe. Low power wireless devices emit low levels of radio frequency energy (RF) in the
microwave range while being used. Whereas high levels of RF can produce health effects (by heating
