3.2 BTM421 FCC and Industry Canada Statements
The user manual must show the following statements:
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.
Changes or modifications not expressly approved by the party responsible for compliance could void the
user’s authority to operate the equipment.
To comply with the FCC RF exposure compliance requirements, this device and its antenna must not be co-
located or operating to conjunction with any other antenna or transmitter.
Considerations for OEM integration:
To inherit the modular approval, the antennas for this transmitter must be installed to provide a separation
distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any
other antenna or transmitter.
Co-location with other radio transmitting devices operating concurrently in the same band will require
additional testing and certification.
Designers should note the distinction that the FCC makes regarding portable and mobile devices. Mobile
devices are defined as products that are not used closer than 20 cm to the human body, whereas portable
devices can be used closer than 20 cm to the body. A device may be used in portable exposure conditions
with no restrictions on host platforms when the averaged output power is less than the low power threshold
for an uncontrolled environment ≤ 60/f(GHz) i.e. 25 mW for a 2.4 Ghz device. The Maximum Power Exposure
for the BTM421 has been evaluated and found to comply with the low power threshold for an uncontrolled
environment.
Refer to FCC document KDB 447498 for more information on RF exposure procedures and equipment
authorization policies for mobile and portable devices.
FCC Labelling requirement
If the FCC ID is not visible when the module is installed inside another device, then the outside of the device
into which the module is installed must also display a label referring to the enclosed module. This exterior
label can use wording such as the following: “Contains Transmitter Module FCC ID: PI4421B” or “Contains
FCC ID: PI4421B.” Any similar wording that expresses the same meaning may be used.
