RabbitCore RCM4400W

1.4  Certifications

The systems integrator and the end-user are ultimately responsible for the channel range 

and power limits complying with the regulatory requirements of the country where the end 

device will be used. Dynamic C function calls and sample programs illustrate how this is 

achieved by selecting the country or region, which sets the channel range and power limits 

automatically. See Section 6.2.4.1 for additional information and sample programs dem-

onstrating how to configure an end device to meet the regulatory channel range and power 

limit requirements.

Only RCM4400W modules bearing the FCC certification are certified for use in Wi-Fi 

enabled end devices, and any applications must have been compiled using Dynamic C v. 

10.21 or later. The certification is valid only for RCM4400W modules equipped with the 

dipole antenna that is included with the modules. Changes or modifications to this equip-

ment not expressly approved by Rabbit Semiconductor may void the user's authority to 

operate this equipment.

In the event that these conditions cannot be met, then the FCC certification is no longer 

considered valid and the FCC ID can not be used on the final product. In these circum-

stances, the systems integrator or end-user will be responsible for re-evaluating the end 

device (including the transmitter) and obtaining a separate FCC certification.

NOTE: Any regulatory certification is voided if the RF shield on the RCM4400W 

module is removed.

1.4.1  FCC Part 15 Class B

The RCM4400W RabbitCore module has been tested and found to comply with the limits 

for Class B digital devices pursuant to Part 15 Subpart B, of the FCC Rules. These limits 

are designed to provide reasonable protection against harmful interference in a residential 

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. However, there is no guarantee that interference 

will not occur in a particular installation. If this equipment does cause harmful interfer-

ence to radio or television reception, which can be determined by turning the equipment 

off and on, the user is encouraged to try and correct the interference by one or more of the 

following measures:

•

Reorient or relocate the receiving antenna.

•

Increase the separation between the equipment and the 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.
