These limits are designed to provide reasonable protectionagainst harmful interference in a residential installation. Thisequipment generates, uses and can radiate radio frequency energy and,if not installed and used in accordance with the instructions, maycause harmful interference to radio communications. However, there isno guarantee that interference will not occur in a particularinstallation. If this equipment does cause harmful interference toradio or television reception, which can be determined by turning theequipment off and on, the user is encouraged to try to correct theinterference 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.4) The final end product must be labeled in a visible area with the following.Contains TX FCC ID:T82HRF-2401Document Name Subject pageProduct Specification HRF-2401(2.4GHz band wireless module) 7/8HERUTU ELECTRONICS CORPORATION
⑥Request to the final product 21) In the instruction manual of the final product, please describe thefollowing sentence.This device complies with part of FCC Rules and 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.Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and 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 chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante.IMPORTANT NOTE: Radiation Exposure StatementThe available scientific evidence does not show that any health problems are associated with using low power wireless devices.There is no proof, however, that these low power wireless devices are absolutely safe. Low power Wireless devices emit low levels of radio frequency energy (RF) in the microwave range while being used. Whereas high levels of RF can produce health effects (by heating tissue), exposure of low-level RF that does not produce heating effects causes no known adverse health effects. Many studies of low-level RF exposures have not found any biological effects. Some studies have suggested that some biological effects might occur, but such findings have not been confirmed by additional research. This device (モデル名) has been tested and found to comply with IC radiationexposure limits set forth for an uncontrolled environment and meets RSS-102 of the IC radio frequency (RF) Exposure rules.Les connaissances scientifiques dont nous disposons n’ont mis en évidence aucun problème de santé associé à l’usage des appareils sans fil à faible puissance. Nous ne sommes cependant pas en mesure de prouver que ces appareils sans fil à faible puissance sont entièrement sans danger. Les appareils sans fil à faible puissance émettent une énergie radioélectrique (RF)très faible dans le spectre des micro-ondes lorsqu’ils sont utilisés. Alors qu’une dose élevée de RF peut avoir des effets sur la santé (en chauffant les tissus), l’exposition à de faibles RF qui ne produisent pas de chaleur n’a pas de mauvais effets connus sur la santé. De nombreuses études ont été menées sur les expositions aux RF faibles et n’ont découvert aucun effet biologique. Certaines études ont suggéré qu’il pouvait y avoir certains effets biologiques, mais ces résultats n’ont pas étéconfirmés par des recherches supplémentaires. モデル名 a été testé et jugé conforme aux limitesd’exposition aux rayonnements énoncées pour un environnement non contrôlé et respecte les règles d’exposition aux fréquences radioélectriques (FR) RSS-102 de l’IC.(モデル名), please fill in the model number of the deviceDocument Name Subject pageProduct Specification HRF-2401(2.4GHz band wireless module) 8/8HERUTU ELECTRONICS CORPORATION
