Introduction
Thank you for purchasing Radicom’s RB540 series Class 1 Bluetooth multimedia module.
We are committed to providing you quality service and technical support. The RB540
series module is designed to meet requirements for long-range wireless audio
functionality. The RB540 series offers a quick and simple solution for adding wireless
audio Bluetooth communications to OEM’s products.
The RB540 series are embedded Class 1 Bluetooth modules using BlueCore5-External
Chipset from CSR, the leader in Bluetooth chipsets. These Bluetooth radio modules
combine Bluetooth Basic Rate (BR) technology to provide increased throughput, reduced
battery consumption and improved security. They also provide faster pairing and allow
superior performance in the presence of interference from 802.11 WiFi wireless devices
and other 2.4GHz radios.
The RB540 series has on board flash memory available to upgrade the module’s
firmware, modify parameters, or implement custom features. Radicom can modify the
firmware to meet OEM requirements and create custom Bluetooth functionality to meet
your specific needs.
The RB540 series supports AV, handset, hands-free wireless profiles to create a
connection between two devices such as MP3/CD players, mobile phones, tablet,
desktop or notebook computers, PDA…etc.
Containing all of the necessary software stacks and hardware I/O, the RB540 series is
perfect for designing a custom Bluetooth Audio product by simply adding components
such as a microphone, speaker, LED, buttons, headset housing, etc.

Federal Communication 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.
IMPORTANT NOTE:
FCC Radiation Exposure Statement:
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 transmitter must not be co-located or operating in conjunction with any other antenna
or transmitter.
10
This device is intended only for OEM integrators under the following conditions:
The transmitter module may not be co-located with any other transmitter or antenna,
As long as 1 condition above is met, further transmitter test will not be required. However,
the OEM integrator is still responsible for testing their end-product for any additional
compliance requirements required with this module installed
IMPORTANT NOTE
In the event that these conditions can not be met (for example certain laptop configurations
or co-location with another transmitter), then the FCC authorization is no longer considered
valid and the FCC ID can not be used on the final product. In these circumstances, the
OEM integrator will be responsible for re-evaluating the end product (including the
transmitter) and obtaining a separate FCC authorization.
End Product Labeling
The final end product must be labeled in a visible area with the following: “Contains FCC ID:
K7T-RB540”.
Manual Information to the End User
The OEM integrator has to be aware not to provide information to the end user regarding
how to install or remove this RF module in the user’s manual of the end product which
integrates this module.
The end user manual shall include all required regulatory information/warning as show in
this manual.
