Wireless-Related Precautions/Indications (Models with a wireless communication
system only)
How to check the wireless certification number: The wireless certification number is included on the label on the side of the
device.
The 5 GHz band wireless access system is for indoors use only.
For the United States of America
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.
FCC CAUTION
changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to
operate the equipment.
Compliance with FCC requirement 15.407(c)
Data transmission is always initiated by software, which is the passed down through the MAC, through the digital and
analog baseband, and finally to the RF chip. Several special packets are initiated by the MAC. These are the only ways the
digital baseband portion will turn on the RF transmitter, which it then turns off at the end of the packet. Therefore, the
transmitter will be on only while one of the aforementioned packets is being transmitted. In other words, this device
automatically discontinue transmission in case of either absence of information to transmit or operational failure.
Frequecncy Tolerance: ±20 ppm
This device must not be co-located or operated in conjunction with any other antenna or transmitter except for Wireless
LAN and Bluetooth module SX-SDMAC-2832S+ R2 which performed co-location testing.
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment and meets the FCC
radio frequency (RF) Exposure Guidelines. This equipment should be installed and operated keeping the radiator at least
20cm or more away from person’s body (excluding extremities: hands, wrists, feet and ankles).
Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15
of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a commercial environment. This equipment generates,
uses, and can radiate radio frequency energy and, if not installed and used in accordance with
the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference in which case the user will be required to correct the interference at
his own expense.
For Canada
This device contains licence-exempt transmitter(s)/receiver(s) that comply with Innovation, Science and Economic
Development Canada’s licence-exempt RSS(s). Operation is subject to the following two conditions:
1.This device may not cause interference.
2.This device must accept any interference, including interference that may cause undesired operation of the device.
L’émetteur/récepteur exempt de licence contenu dans le présent appareil est conforme aux CNR d’Innovation, Sciences et
Développement économique 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;

4/161
RICOH SC-20
Operating Instructions Rev. 1.0.0
2.L’appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d’en compromettre le
fonctionnement.
5150-5350 MHz band is restricted to indoor operation only.
La bande 5150-5350 MHz est restreinte à une utilisation à l’intérieur seulement.
Compliance with ISED requirement RSS-247 6.4 a) Data transmission is always initiated by software, which is the passed
down through the MAC, through the digital and analog baseband, and finally to the RF chip. Several special packets are
initiated by the MAC. These are the only ways the digital baseband portion will turn on the RF transmitter, which it then
turns off at the end of the packet. Therefore, the transmitter will be on only while one of the aforementioned packets is
being transmitted. In other words, this device automatically discontinue transmission in case of either absence of
information to transmit or operational failure.
Conformité à la norme CNR-247 6.4 a) La transmission des données est toujours initiée par le logiciel, puis les données
sont transmises par l'intermédiaire du MAC, par la bande de base numérique et analogique et, enfin, à la puce RF.
Plusieurs paquets spéciaux sont initiés par le MAC. Ce sont les seuls moyens pour qu'une partie de la bande de base
numérique active l'émetteur RF, puis désactive celui-ci à la fin du paquet. En conséquence, l'émetteur reste uniquement
activé lors de la transmission d'un des paquets susmentionnés. En d'autres termes, ce dispositif interrompt
automatiquement toute transmission en cas d'absence d'information à transmettre ou de défaillance.
This equipment complies with IC radiation exposure limits set forth for an uncontrolled environment and meets RSS-102 of
the IC radio frequency (RF) Exposure rules. This equipment should be installed and operated keeping the radiator at least
20cm or more away from person’s body. (excluding extremities: hands, wrists, feet and ankles).
Cet équipement est conforme aux limites d’exposition aux rayonnements énoncées pour un environnement non contrôlé et
respecte les règles d’exposition aux fréquences radioélectriques (RF) CNR-102 de l’IC. Cet équipement doit être installé et
utilisé en gardant une distance de 20 cm ou plus entre le radiateur et le corps humain.(à l’exception des extrémités : mains,
poignets, pieds et chevilles)

3. Overview of SC-20
SC-20 can be used to judge the degree of similarity of a master image and camera image.
It supports automatic judgment by the pattern matching function and manual judgment by visual checking.
SC-20 has three work modes.
1. Matching mode
2. Check mode
3. Data input mode
Register a combination of work modes to the workflow and then operate the device.
For details on the workflow, see the “Configuration example of workflow” below.
Creating a Workflow (→P. 38)
1. Matching mode:
This mode judges the degree of similarity (shape pattern, color, or texture) of a master image and camera image using
the pattern matching function.
The matching methods are as described below.
Relative search:
If an anchor point has been set when creating the workflow, this method makes a judgment by searching for the
anchor point from the camera image and searching for the check points according to the relative position from the
anchor point.
Absolute search:
If an anchor point has not been set when creating the workflow, this method assumes the top left of the camera
image as the reference position (x: 0, y: 0), and makes a judgment by searching for the check points according to
the absolute position from the reference position.
Use an absolute search when the target is fixed.
Matching mode execution screen:
Displays the image set for the
check points.
