Information about FCC Standard and IC standard.
This device complies with Part 15 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 la partie 15des règles de la FCC et 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

12

Wireless Remote Control Switch

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 thatthe equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successfulcommunication.
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 desautres 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 Statement
The 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 havesuggested that some biological effects might occur, but such findings have not been confirmed byadditional research. This device (HRF-2401) has been tested and found to comply with IC radiation
exposure 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 desanté 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. Certainesétudes ont suggéré qu’il pouvait y avoir certains effets biologiques, mais ces résultats n’ont pas été
confirmés par des recherches supplémentaires. HRF-2401 a été testé et jugé conforme aux limites
d’exposition aux rayonnements énoncées pour un environnement non contrôlé et respecte lesrègles d’exposition aux fréquences radioélectriques (FR) RSS-102 de l’IC.

After the button of a transmitter is pushed, although the relay output of a receiver turns on and off, the following
delay time occurs also at the place where communication environment is good.
Moreover, since it generates not only in the following delay time at the place that communication environment is
bad and a communication fault occurs frequently, please use after comprehension.

◆When you use two or more these products in the same area, please detach receivers, transmitters or atransmitter, and the receiver at least 50 cm or more, and install them.
◆Communication distance
Although standard communication distance is indoor about 20 m/outdoor about 50m, since communication
distance changes with setting methods, please use the communication distance of this product after anunderstanding.
When you use by “Through”, the output from a receiver may turn off momentarily according to communication
environment or communication distance. Moreover, if two or more sets are used simultaneously in the same area,even when the channel table is being made a different setup, the output from a receiver may be turned off
momentarily. You understand the characteristic of this product, please cope with that I have you hold by theconnection apparatus side etc., and use.
