PCB Layout
FCC Statment
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 or more 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.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
- this device may not cause harmful interference
- This device must accept any interference received, including interference that may cause undesired operation.
Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment.
IMPORTANT NOTE:
FCC RF 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 a minimum distance of 2.5 cm between the radiator & your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
- This device is intended only for OEM integrators under the following conditions: The antenna must be installed such that 2.5 cm is maintained between the antenna and users, and the transmitter module may not be co-located with any other transmitter or antenna.
- As long as the 2 conditions above are met, further transmitter tests 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 (for example, digital device emissions, PC peripheral requirements, etc.).
- If the FCC identification number and IC certification number are 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 FCC ID: 2BFPP-MT200C’ and ‘Contains IC: 34741-MT200C ’. Any similar wording that expresses the same meaning may be used.”
This module has been tested and should be used with the antennas:
| Antenna Type | Peak Gain (dBi) | Part Name |
| PCB Pattern Antenna | 3.0 | – |
RSS-GEN Section 7.1.3
This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject to the following two conditions:
- this device may not cause interference
- this device must accept any interference, including interference that may cause undesired operation of the device.
