3.Operating explanation
HRF-2401 do a pairing with an equipment to communicate before wireless
communicating.
Piring way is different by a specification of included the interface
electric substract.
One is to match each ID by dipswitch,one is transmitter send ID data by
registration switch,receiver register the ID data received from
transmitter.
There are several ways for registration by customer specification.
Each equipment done a paring communicates by using 1ch among 4ch selected
from 76ch.
Each equipment can receive an answer back by setting.
Input and output terminal can be connected a keyboard,a LED and a LCD etc.
It is programed by costomer request.

Use other antenna may subject to additional testing and filing to FCC.
②Chip antenna
When you use a HRF-2401 of chip antenna specification,communication distance
may be short noticeably.
Then please get a clearance around the antenna as far as possible.
③All kinds protection circuit
This module recommends to include a protection circuit according to the use
because a protection circuit from static electricity isn't included
in a port variously.
④Power source
A minimum of a operation voltage is set to 2.05V,because a regulator of 2V
is mounted on this module.
Please take the measure which stops a malfunction of a circuit using voltage
detection IC by used battery and power unit.
⑤Request to the final product 1
1) Please include the following sentence on the final product.
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.
2) In the instruction manual of the final product, please describe the
following sentence.
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 mustfollow the specific operating instructions for satisfying RF
exposure compliance. This transmitter must not be co-located or operating in conjunction

3) For a Class B digital device or peripheral, the instructions
furnished the user shall include the following or similar statement,
placed in a prominent location in the text of the manual
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 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 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.

⑥Request to the final product 2
1) In the instruction manual of the final product, please describe the
following 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 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 (モデル名) 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. モデル名 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.
(モデル名), please fill in the model number of the device
