. 7FCC Warning:
JOHNSONINDUSTRIES(SHANGHAI)CO.,LTD. Any Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. 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. The modular transmitter must be equipped with either a permanently affixed label or must be capable of electronically displaying its FCC identification number If using a permanently affixed label, the modular transmitter must be labeled with its own FCC identification number. and, 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 Transmitter Module FCC ID:2AKDB-WLT2564M. Any similar wording that expresses the same meaning may be used. The Grantee may either provide such a label, an example of which must be included in the application for equipment authorization, or, must provide adequate instructions along with the module which explain this requirement. In the latter case, a copy of these instructions must be included in the application for equipment authorization. FCC Radiation Exposure Statement:
To satisfy FCC RF Exposure requirements for this transmission devices, a separation distance of 20cm or more should be maintained between the antenna of this device and persons during operation. To ensure compliance, operation at closer than this distance is not recommended. The antenna(s) used for this transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. 8ISED RSS Warning:
This device complies with Innovation,Science and Economic Development 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 prsent appareil est conforme aux CNR d'ISED applicables aux appareils radio exempts de licence. L'exploitation est autorise aux deux conditions suivantes:
(1) l'appareil ne doit pas produire de brouillage, et
(2) l'utilisateur de l'appareil doit accepter tout brouillage radiolectrique subi, mme si le brouillage est susceptible d'en compromettre le fonctionnement. ISED RF exposure statement :
This equipment complies with ISED RF radiation exposure limits set forth for an uncontrolled environment .This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. Cet quipement est conforme aux ISED RF limites d'exposition aux radiations dans un environnement non contrl. Cet metteur ne doit pas tre situ ou oprant en conjonction avec une autre antenne ou metteur. 2/15/2016 9/9
