PCB Layout Recommendations Please reference Mechanical Dimensions shown in next section for PCB layout. The area underneath the module should be covered with solder mask in order to prevent short circuit on the test pads on the back side of the module. A solid ground plane under the module is preferred. As the module integrated with onboard PCB trace antenna, the mounting position of the module will have great impact on the RF performance. There should not be any trace, ground plane or metal part underneath or nearby the area of the onboard PCB trace antenna. The figure below shows an example how the module positioned on the mother PCB. Figure 4: A recommended placement of the module on a main PCB

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. (2) This device must accept any interference received, including interference that may cause undesired operation. Part 15.21 2. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. Part 15.105 NOTE: 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 2.1091 For purposes of this section, a mobile device is defined as a transmitting device designed to be used in other than fixed locations and to generally be used in such a way that a separation distance of at least 20 centimeters is normally maintained between the transmitter's radiating structure(s) and the body of the user or nearby persons. In this context, the term “fixed location” means that the device is physically secured at one location and is not able to be easily moved to another location. Transmitting devices designed to be used by consumers or workers that can be easily re-located, such as wireless devices associated with a personal computer, are considered to be mobile devices if they meet the 20 centimeter separation requirement. If the FCC identification number is not visible when the module is installed inside anotherdevice, then the outside of the device into which the module is installed must also display alabel referring to the enclosed module. This exterior label can use wording such as thefollowing: “Contains Transmitter Module FCC ID: DI2-CTL3573A
ZigBee- Ready RF Transceiver Module CTL3570/1/2/3 Copyright © 2011 Computime Limited. All rights reserved. Rev. 3 Canada information: This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement. IC RF warning statement This equipment complies with IC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator & your body. If the IC identification number is not visible when the module is installed inside anotherdevice, then the outside of the device into which the module is installed must also display alabel referring to the enclosed module. This exterior label can use wording such as thefollowing: “Contains Transmitter Module IC: 1700D-CTL3573AUnder Industry Canada regulations, this radio transmitter may only operate using an antenna of a typeand maximum (or lesser) gain approved for the transmitter by Industry Canada.To reduce potential radio interference to other users, the antenna type and its gain should be so chosenthat the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successfulcommunication.
