Federal Communications Commission
Interference Statement
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 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 Caution: Any changes or modifications not expressly approved by the party responsible
for compliance could void the user's authority to operate this equipment.
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.
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.
This device and its antenna(s) must not be co-located or operating in conjunction with any
other antenna or transmitter. This product must be installed by a professional
technician/installer.

5.2 Maximum Permissible Exposure (MPE)
5.2.1 Introduction
This section has been prepared on behalf of CSL FHSS RFID Device to show compliance with
the RF exposure requirements as defined in FCC §1.1307.
5.2.2 Requirements
Three different categories of transmitters are defined by the FCC in OET Bulletin 65.
categories are fixed installation, mobile, and portable and are defined as follows:
These
Fixed Installations: fixed location means that the device, including its antenna, is
physically secured at a permanent location and is not able to be easily moved to another
location. Additionally, distance to humans from the antenna is maintained to at least 2
meters.
Mobile Devices: a mobile device is defined as a transmitting device designed to be used
in other than fixed locations and to be generally used in such a way that a separation
distance of at least 20 centimeters is normally maintained between the transmitter's
radiating structures and the body of the user or nearby persons. Transmitters designed to
be used by consumers or workers that can be easily re-located, such as a wireless modem
operating in a laptop computer, are considered mobile devices if they meet the 20
centimeter separation requirement. The FCC rules for evaluating mobile devices for RF
compliance are found in 47 CFR §2.1091.
Portable Devices: a portable device is defined as a transmitting device designed to be
used so that the radiating structure(s) of the device is/are within 20 centimeters of the
body of the user. Portable device requirements are found in Section 2.1093 of the FCC's
Rules (47 CFR§2.1093).
This CSL RFID device with 5dBiC antenna (CS771S-2) is considered a fixed installation as it
is used for the purpose of reading tags.
The FCC also categorizes the use of the device as based upon the user’s awareness and ability
to exercise control over his or her exposure. The two categories defined are Occupational/
Controlled Exposure and General Population/Uncontrolled Exposure.
are defined as follows:

These two categories

USER'S MANUAL, VERSION 0.0
Occupational/Controlled Exposure: In general, occupational/controlled exposure limits are
applicable to situations in which persons are exposed as a consequence of their
employment, who have been made fully aware of the potential for exposure and can
exercise control over their exposure. This exposure category is also applicable when the
exposure is of a transient nature due to incidental passage through a location where the
exposure levels may be higher than the general population/uncontrolled limits, but the
exposed person is fully aware of the potential for exposure and can exercise control over
his or her exposure by leaving the area or by some other appropriate means. Awareness
of the potential for RF exposure in a workplace or similar environment can be provided
through specific training as part of a RF safety program. If appropriate, warning signs
and labels can also be used to establish such awareness by providing prominent
information on the risk of potential exposure and instructions on methods to minimize
such exposure risks.
General Population/Uncontrolled Exposure: The general population / uncontrolled
exposure limits are applicable to situations in which the general public may be exposed or
in which persons who are exposed as a consequence of their employment may not be
made fully aware of the potential for exposure or cannot exercise control over their
exposure. Members of the general public would come under this category when
exposure is not employment-related; for example, in the case of a wireless transmitter that
exposes persons in its vicinity. Warning labels placed on low-power consumer devices
such as cellular telephones are not considered sufficient to allow the device to be
considered under the occupational/controlled category,
population/uncontrolled exposure limits apply to these devices.

CS469-2 is a 4 port reader where the ports are switched on in time one by
one. At any time only 1 port is switched on and the RF power comes out
only at that port. The rest of the ports are turned off so that no energy
comes out from the other ports.
The control logic of the antenna is shown as below table

USER'S MANUAL, VERSION 0.0
Appendix A. RFID Basics
Passive tag RFID technology involves the reader, the antenna and the tag.
The reader sends out energy in the relevant frequency band to the antenna via RF cables, and
the antenna radiates the energy out. This energy impinges on an RFID tag.
The RFID tag consists of an antenna coupled to an RFID IC. This IC converts the AC voltage
it receives at the antenna port to DC voltage that in turn is used to empower the digital circuit
inside.
The digital circuit then turns on and off some components connected to the antenna port,
thereby changing its scattering behavior, in a pre-designed clock rate.
This changing of antenna port parameters then causes a “modulation” of the back-scattered RF
energy.
This modulated back-scattered energy is detected by the reader and the modulation is captured
and analyzed.
