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 t o 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 o r 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 us er‘s authority to operate

23

the equipment.

FCC RF Exposure Information (SAR)

This device is designed and manufactured not to exceed the emission

limits for e xposure 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 u sage against the head with no separation,

and near the body with the separation of 5 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 clo ser 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.

Tests for SAR are conducted using standard operating positions

accepted by the FCC with the device transmitting at its highest certified

power level in all tested frequency bands.

24

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

www.fcc.gov/oet/ea/fccid after searching on

FCC ID: SRQ-MF79U.

For this device, the highest reported SAR value for near the body is

0.95 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 5 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 o r 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.
