refer to recommended scheme 1 or scheme 2; the effect of schemes 3, 4 and 5 is bad, so please avoid those schemes
when designing the product.
3.2.1 Recommended Scheme
Scheme 1: Antenna is out of the Board Scheme 2: Antenna is at Board Edges with Keep-
Space
3.2.2 Not Recommended Schemes
Actually measured effects of schemes 3, 4 and 5 are bad. Please do not use those three schemes when
designing product.
Scheme 3: Antenna is at Board Edges Scheme 4: Antenna is in Board Frame

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.

CSM64F02 User Manual
Rev1.2 Page 10 of 13
—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.
This device complies with part 15 of the FCC rules. Operation is subject to the following twoconditions:
(1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may cause undesired
operation.
Changes or modifications to this unit not expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment.

Attention:
① Modem-Sleep is used for the application requiring CPU always in operating state such as PWM or I2S
applications etc. When maintaining Wi-Fi connection, it is allowed to turn off Wi-Fi Modem circuit to save
power consumption according to 802.11 standard (such as U-APSD) when there is no data transmission. For
example, in the configuration ofDTIM3, it will wake up for 3ms to receive Beacon packet fromAP after sleeping
every 300ms, and the averange current is about 15mA.
② Light-Sleep is used for the application with CPU suspendable such as Wi-Fi switch. When maintaining Wi-Fi
connection, it is allowed to turn off Wi-Fi Modem circuit and suspend CPU to save power consumption
according to 802.11 standard (such as U-APSD) when there is no data transmission. For example, in the event
of DTIM3, it will wake up for 3ms to receive Beacon packet from AP after sleeping every 300ms, and the
averange current will be about 9mA.
③ Deep-Sleep is used for the application without the need to always maintain Wi-Fi connection and transmitting
one data packet for a long time such as the sensor measuring temperature every 100s. For example, it will wake
up for 0.3s - 1s every 300s and connect to AP to transmit data, and the averange current may be far smaller than
1mA.

Host 15B and 15C compliance statement
A host product itself is required to comply with all other applicable FCC equipment
authorization regulations, requirements, and equipment functions that are not
associated with the transmitter module portion. For example, compliance must be
demonstrated: to regulations for other transmitter components within a host product;
to requirements for unintentional radiators (Part 15 Subpart B), such as digital
devices, computer peripherals, radio receivers, etc.; and to additional authorization
requirements for the non-transmitter functions on the transmitter module (i.e.,
Verification or Declaration of Conformity) as appropriate (e.g., Bluetooth and Wi-Fi
transmitter modules may also contain digital logic functions).
The OEM integrator or the host manufacturer is responsible for the overall
compliance of the host products
FCC statement
This device complies with Part 15 of 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.
RF exposure statement
Human exposure to RF emissions from mobile devices (47 CFR §2.1091) may be
evaluated based on the MPE limits adopted by the FCC for electric and magnetic field
strength and/or power density, as appropriate, since exposures are assumed to
occur at distances of 20 cm or more from persons.
Module statement
The single-modular transmitter is a self-contained, physically delineated, component
for which compliance can be demonstrated independent of the host operating
conditions, and which complies with all eight requirements of § 15.212(a)(1) as
summarized below.
1) The radio elements have the radio frequency circuitry shielded.
2) The module has buffered modulation/data inputs to ensure that the device will
comply with Part 15 requirements with any type of input signal.
