3.1 BTM420 FCC and Industry Canada Statements

The Final Equipment 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:

This module has a limited modular approval. Approval with any other antenna configuration or layout other

than that approved will necessitate additional radiated emission testing to be performed.

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.

This module was approved with the following antenna:



RF Solutions: ANT-24G-WHJ-SMA 0 dBi

Operation of this module with any other antenna will require additional testing to be performed.

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 BTM420 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: PI4420B” or “Contains

FCC ID: PI4420B.” Any similar wording that expresses the same meaning may be used.
