1. Introduction
This SCW-K240 is a detector that is able to detect the moving objects. It is based on
the Doppler effect and generated by 24GHz. This module consists of a couple of
major parts which are called the RF sensing and signal processing parts.

3. Operating process
After detecting some movement on the device, the interrupt signal from the sensor is
generated. Then, the electrical power is sent to the sensor. Once the sensor is operating, the
output of INT will be steady at high level. If the device is detecting some movement, the
output of the INT is shortly maintained at low level and goes back to the high level as shown
in Figure below.

This module is contained the RF sensing part and the signal processing part
which are the green and brown panels respectively represented as a figure below.

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.
FCC Warning:
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,
(2) this device must accept any interference received, including interference that may cause
undesired operation.
FCC Caution:
Any changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate this equipment.
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with minimum distance 20cm
between the radiator & your body

Cet appareil numérique de la classe B est conforme á la norme NMB-003 du Canada.
This device complies with 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.
IC Radiation Exposure Statement:
This equipment complies with IC RSS-102 radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with minimum
distance 20cm between the radiator & your body
Cet équipement est conforme avec IC RSS-102 des limites d'exposition aux rayonnements
définies pour un environnement non contrôlé. Cet équipement doit être installé et utilisé à
distance minimum de 20cm entre le radiateur et votre corps
This device and its antenna(s) must not be co-located or operation in conjunction with
any other antenna or transmitter.
Cet appareil et son antenne (s) ne doivent pas être co-localisés ou fonctionnement en
association avec une autre antenne ou émetteur.
