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. The FCC requires the user to be notified that any changes or modifications not expressly approved by SyChip, Inc. may void the users authority to operate the equipment. While an application of the SN3020 module in a product is not required to obtain a new FCC authorization for the module, this does not preclude the possibility that some other form of authorization or testing may be required for that end product. SyChip/Murata Confidential Page 23 of 26 SN3020 User Manual 1.0 This device using the integrated antenna has been tested to comply with FCC CFR Part 15. The device meets the requirements for modular transmitter approval as detailed in the FCC public notice DA00.1407.transmitter given the following considerations:
Maximum output power level for the channels as defined by IEEE 802.15.4 [1] must be set to the value below using emberSetRadioPower or equivalent under NORMAL mode as specified in [2]. o For channels 11 to 24, the value of -11 o For channel 25, the value of -17 o For channel 26, the value of -27 Duty cycle of 67% allowed. The firmware disables power out if the source voltage is greater than 3.4V. VBATT must be between 2.4V 3.4V. 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, or consult the dealer or an experienced radio/TV technician for help. 11.1.1 FCC Labeling Requirements When integrating the SN3020 into a product the FCC labeling requirements must be met. This includes a clearly visible label on the outside of the finished product specifying the SN3020 FCC identifier (FCC ID:QPU3020) as well as the notice above. The exterior label can use wording such as Contains Transmitter Module FCC ID:QPU3020 or Contains FCC ID:QPU3020 although any similar wording that expresses the same meaning may be used. 11.1.2 RF Exposure This module has been certified for remote and base radio applications and is not intended to be operated within 20cm of the body. If the module will be used for portable applications, the device must undergo SAR testing. The following statement must be included as a CAUTION statement in manuals for the products to alert users on FCC RF exposure compliance:
WARNING: To satisfy FCC RF exposure requirements for mobile transmitting devices, a separation distance of 20cm or more should be maintained between the antenna of this device and persons during operation. To ensure compliance, operations at closer distances than this are not recommended. SyChip/Murata Confidential Page 24 of 26 SN3020 User Manual 1.0 11.2 IC Notice (Canada) The term IC before the certification/registration number only signifies that the Industry Canada technical specifications were met. Le terme IC devant le numro de certification /denregistrement signifie seulement que les spcifications techniques Industrie Canada ont t respectes. This device complies with Health Canadas Safety Code 6 / IC RSS-210. The installer of this device should ensure that RF radiation is not emitted in excess of the Health Canadas requirement. Information can be obtained at: http://www.hc-sc.gc.ca/ewh-semt/pubs/radiation/radio_guide-

semt/pubs/radiation/radio_guide-lignes_direct-eng.php The host device should be properly labeled to identify the module within the host device. The Industry Canada certification label of a module shall be clearly visible at all times when installed in the host device, otherwise the host device must be labeled to display the Industry Canada certification number of the module, preceded by the words Contains transmitter module, or the word Contains, or similar wording expressing the same meaning, as follows:
Contains transmitter module IC:4523A-SN3020 where 4523A-SN3020 is the modules certification number. 11.3 CE Notice (Europe) This device has been tested and certified for use in the European Union. If this device is used in a product, the OEM has responsibility to verify compliance of the final product to the EU standards. A Declaration of Conformity must be issued and kept on file as described in Annex II of the Radio and Telecommunications Terminal Equipment Directive. The CE mark must be placed on the OEM product per the labeling requirements of the Directive. Given that the operating frequency band is not harmonized by a few European countries, the restriction or alert sign must be placed along side the CE mark as shown below. As of the date of this document, only France has a restriction. The restriction is that, if the radio is operated outdoors in the 2450-2483.5 MHz band, the power must be limited to 10 mW instead of 100 mW. The OEM must account for this and the product must have the alert mark. It does not require country notifications, however.
