Federal Communication Commission Statement (FCC, U.S.) 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.
Information that must be placed in the end user manual: The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module in the user's manual of the end product which integrates this module. The end user manual shall include all required regulatory information/warning as show in this manual.
Integration instructions for host product manufacturers according to KDB 996369 D03 OEM Manual v01 2.2 List of applicable FCC rules FCC Part 15 Subpart C 15.247 & 15.207 & 15.209 2.3 Specific operational use conditions The module is a WIFI module with WIFI 2.4G function. Operation Frequency: 2412~2462MHz Number of Channel: 11 Modulation: 802.11b CCK; 802.11g/n OFDM Type: FPC Antenna Gain: 1.5 dBi The module can be used for mobile or applications with a maximum 1.5dBi antenna.
2.9 Information on test modes and additional testing requirements Operation Frequency: 2412~2462MHz Number of Channel: 11 Modulation: 802.11b CCK; 802.11g/n OFDM Host manufacturer must perfom test of radiated & conducted emission and spurious emission, etc according to the actual test modes for a stand-alone modular transmitter in a host, as well as for multiple simultaneously transmitting modules or other transmitters in a host product.
FCC STATEMENT : 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. Warning: Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.
