3 The upper right corner is the power supply module;

4 Other conventional resistors are connected in series with the main chip RV1126 to limit current or facilitate debugging. 5 Later layout (such as layout diagram) will keep this layout unchanged. 6The RV1126 feeds the module 32.768kHz through an I/O port to control the status of the module. 7The 26MHz crystal perk is used to make the module work properly. 6.Certification 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 Shenzhen Topband Co.,Ltd. www.topband.com.cn 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. This equipment 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. Any changes or modifications not expressly approved by the party responsible for compliance could void the users authority to operate the equipment. Please notice that if the FCC identification number 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. This exterior label can use wording such as the following: Contains FCC ID: 2ADDW-BT241 any similar wording that expresses the same meaning may be used. FCC RF Radiation Exposure Statement Caution: To maintain compliance with the FCCs RF exposure guidelines, place the product at least 20cm from nearby persons. This is a limited modular approval, Class 2 perissive change needed if the layout out of the modular shielding changed when integrated into the Host device This LMA can only be used when the Grantee is the host manufacturer for a series of similar host models to allow the host and the module to share compliance responsibilities. When receiver detection is required (i.e., DFS, CBP), the certified antenna must be unrestricted by the host and, when used in a host and based on current policy, requires the module to be reviewed on a case-by-case base by submitting an equipment compliance review inquiry to confirm that the integration instructions will include strict guidance for antenna location for receiver detection. Shenzhen Topband Co.,Ltd. www.topband.com.cn This device complies with Industry Canadas licence-exempt RSSs. 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 prsent appareil est conforme aux CNR dIndustrie Canada applicables aux appareils radio exempts de licence. Lexploitation est autorise aux deux conditions suivantes : (1) lappareil ne doit pas produire de brouillage; (2) lutilisateur de lappareil doit accepter tout brouillage radiolectrique subi, mme si le brouillage est susceptible den compromettre le fonctionnement. Please notice that if the ISED certification number 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. This exterior label can use wording such as the following: Contains IC: 23804-BT241 any similar wording that expresses the same meaning may be used. l'appareil hte doit porter une tiquette donnant le numro de certification du module d'Industrie Canada, prcd des mots Contient un module d'mission , du mot IC: 23804-BT241 ou d'une formulation similaire exprimant le mme sens. This equipment should be installed and operated with minimum distance 20cm between the radiator & your body.
