1.General Outline
RC-242 and RC-248 series are the remote control switches of the 2 point type and 8 point type which uses 2.4GHz
bandwidth radio.You have arranged abundantly variations, such as a push button transmitter and a contact input
transmitter, and can use in various combination.

Wireless Remote Control Switch

<Feature>
◆Reliable communication
The frequency (2.4GHz bandwidth) of 64ch is divided into 16 groups, and it communicates by setting up one
arbitrary group.
4ch dispersed, respectively is assigned to one group, and it communicates by making channel selection
automatically. (Frequency hopping function)
When using it in answer back mode, wireless transfer of the signal is certainly carried out by two-way
communication.
(The check of communication OK/NG by LED of a transmitter is possible.)
◆Transmitter uses AAA type battery cell x2.(Alkaline dry cell)
◆Small transmitter uses coin battery (CR2032).
◆The power supply of a contact transmitter is DC12-24V.
It can be used by AC100-240V by using onerous opition AC/DC adapter.
◆The protective cover for preventing breakage and dirt attaches to a transmitter.
(These products are not drip-proof and water-proof specification.)
◆It can be installed a strap with a small transmitter.(Onerous option.)
◆The power supply of a receiver is DC24V.It can be used by AC 100-240V by using an attached AC/DC adaptor.
◆The communication distance is approx 20m(inside),50m(outside)
Communication distance changes with environment. Moreover, it changes with how to use this product.
(Latch output / Through output, and with the answer back/ not)
The above-mentioned numerical value is a standard and is not a guaranteed performance.
Since we are preparing the demo machine, we recommend you that you have a prior communication test etc.

■FCC/IC Warning (HRF-2401)
Information about FCC Standard.
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 interface, and (2) This device must accept any interface received,
including interface that may cause undesired operation:
Caution: The user is cautioned that changes or modifications not expressly approved by the party
responsible for compliance could void the user’s authority to operate the equipment.
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment.
End users must follow the specific operating instructions for satisfying RF exposure compliance. Thai
transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
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 will not occur in 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.
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
tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le
fonctionnement.

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 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 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 have
suggested that some biological effects might occur, but such findings have not been confirmed by
additional 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 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 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 les
règles d’exposition aux fréquences radioélectriques (FR) RSS-102 de l’IC.
