FCC Information

This device complies with part 15 of the FCC Results. Operation is subject to the

following two conditions :

(1) This Device may not cause harmful interface, and

(2) This device must accept any interference received, including interference that

may cause undesired operation.

Note: This equipment has been tested and found to comply with the limits for CLASS B digital

device, pursuant to Part 15 of FCC Rules. These limits are designed to provide reasonable

protection against harmful interference when the equipment is operated in a commercial

environment This equipment generates, uses and can radiate 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

correct the interference by one or more of the following measures:

1.1. Reorient or relocate the receiving antenna.

1.2. Increase the separation between the equipment and receiver.

1.3. Connect the equipment into an outlet on a circuit different from that to which receiver is

connected.

1.4. Consult the dealer or experienced radio/TV technician for help.

WARNING

Changes or modifications not expressly approved by the manufacturer could void the

user’s authority to operate the equipment.

“CAUTION : Exposure to Radio Frequency Radiation.

Antenna shall be mounted in such a manner to minimize the potential for human

contact during normal operation. The antenna should not be contacted during operation

to avoid the possibility of exceeding the FCC radio frequency exposure limit.

OEM Responsibilities to comply with FCC Regulations

The SBT-M1 Module has been certified for integration into products only by OEM integrators under the

following conditions:

-. The antenna(s) must be installed such that a minimum separation distance of 5mm is

maintained between the radiator (antenna) and all persons at all times.

-. The transmitter module must not be co-located or operating in conjunction with any other

antenna or transmitter.

As long as the two conditions above are met, further transmitter testing will not be required. However, the

OEM integrator is still responsible for testing their end-product for any additional compliance requirements

required with this module installed (for example, digital device emissions, PC peripheral requirements,

etc.).

IMPORTANT NOTE: In the event that these conditions cannot be met (for certain configurations or co-

location with another transmitter), then the FCC authorization is no longer considered valid and the FCC

ID cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for

re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization.

Maximum antenna gain allowed for use with this device is 3.5 dBi

End Product Labeling

The SBT-M1 Module is labeled with its own FCC ID. If the FCC ID is not visible when the module is

installed inside another device, then the outside of the device into which the module is installed must also

display a label referring to the enclosed module. In that case, the final end product must be labeled in a

visible area with the following:

“Contains Transmitter Module FCC ID: WF5SBTM1”

or

“Contains FCC ID: WF5SBTM1”
