OEM Installation Guide
Installation Notes
• Multi-surface pads provide both bottom pads for high volume reflow soldering and edge pads for low
volume hand soldering.
• Power supply to module should have less than 10mVrms noise between 0-10MHz, and spikes should be
minimal.

• Regulator should have a fast response time < 20µs. It is essential that the power rail recover quickly.
• 10µF or larger capacitor filter for VDD input.
• All unused pins should be unconnected.
• A surface mount antenna should be placed very near the module RF output pin using a 50 ohm
transmission line, and should be designed according to antenna manufacturer specifications.
• The area around the module should be free of any ground planes, power planes, trace routings, or
metal. Minimum clearance is 5mm, but additional clearance allows improved range and throughput.
• Recommend connections for all four UART pins (DB-9 connector or test points) for firmware updates.
• Recommend test points for all four SPI pins, for emergency factory debugging and firmware reloading.
• Do not clean modules with Alcohol which can interact with no-clean solder flux residue.
• Do not use ultra sonic cleaning, which may cause internal interconnect damage.
• Do not modify any hardware components on the module without prior written consent.
• Do not modify any firmware without prior written consent.
• Final products that contain a Radio Datacom Bluetooth Module device must display a visible label
referring to the enclosed module similar to the following label:

Limited Modular Approval FCC ID: XS25200
In accordance with FCC Part 15, the device is listed as a "Limited Modular Transmitter" device. In support of
the Modular Transmitter Approval, the following is stated:
• The module does have buffered modulation / data inputs.
• The module does regulate its own power supply.
• The module can be tested as a stand-alone device.
• The module is labeled with the proper FCC ID, and labeling instructions are provided to OEM end users
for external product labels.
• The module does have instruction for proper use.
• The module does meet the FCC RF regulations.
Limited Modular Transmitter Approval, is granted, instead of Modular Transmitter Approval, because the
following condition is not met:
sales@radiodatacom.com
• The module does not have a permanently attached antenna.
• The module does not have its own RF shielding.
In accordance with FCC document, DA 00-1407, all authorized usage by OEMs under this Limited Modular
Approval grant must:
• Comply with all instructions in this OEM Installation Guide.
• Obtain final compliance approval by Radio Datacom.
