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. Part 15.105 Statement (Class B) 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. Part 15.21 Statement Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. This device must not be co-located or operating in conjunction with any other antenna or transmitter.

12 / 10 Regulatory Notice Regulatory notice to host manufacturer according to KDB 996369 D03 OEM Manual List of applicable FCC rules This module has been granted modular approval as below listed FCC rule parts. -
FCC Rule parts 15C(15.247) 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 in this instruction manual. RF exposure considerations The module has been certified for integration into products only by OEM integrators under the following condition:
-The antenna(s) must be installed such that a minimum separation distance of at least 20 cm 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 except in accordance with FCC multi-transmitter product procedures.
-Mobile use As long as the three 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. LG Innotek Confidential : This document is protected by security policies and laws.
