Compliance with FCC Rules and Regulations

FCC Identifier: BEJ-LW9880G

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 equipment 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 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 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.

Any changes or modifications in construction of this device which are not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.

Regulatory notice to host manufacturer according to KDB 996369 D03 OEM Manual List of applicable FCC rules

• FCC Part 22, 24, 27, 90 of the FCC rules.
  Summarize the specific operational use conditions

• The OEM integrator should use equivalent antennas which is the same type and equal or less gain then an antenna listed below this instruction manual.
  Limited module procedures

• The module is a single module.
  Trace antenna designs

• The module with trace antenna designs, and the Antenna Specification document includes the layout of trace design and measurement data.

RF exposure considerations

• This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
• This equipment should be installed and operated with a minimum distance of 20 cm (7.8 inches) between the antenna and your body. Users must follow the specific operating instructions for satisfying RF exposure compliance.

Mobile use

• As long as the conditions above are met, further transmitter testing will not be required.
• OEM integrators should provide the minimum separation distance to end users in their end-product manuals.

Antennas:

• This module is certified with the following integrated antenna.
• Max. Antenna gain: 3.08 dBi / Ant. Type: Carrier press Type
  Any new antenna type, higher gain than listed antenna should be met the requirements of FCC rule 15.203 and 2.1043 as permissive change procedure.

Label and compliance information

• The 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 FCC ID: BEJ-LW9880G”

Information on test modes and additional testing requirements

• 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, additional transmitter in the host, etc.). Additional testing, Part 15 Subpart B disclaimer
• The final host product also requires Part 15 subpart B compliance testing with the modular transmitter installed to be properly authorized for operation as a Part 15 digital device.
