FCC warning statements

This equipment has been tested and found to comply with the limits for a Class B digital device, under 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 under 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 the receiver.
• Connect the equipment to 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.

Caution: Any changes or modifications to this device not explicitly approved by the manufacturer could void your 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. The device has been evaluated to meet general RF exposure requirements.

The module can be used for mobile applications with a maximum 4 dBi antenna. The host manufacturer installing this module into their product must ensure that the final composite product complies with the FCC requirements by a technical assessment or evaluation of the FCC rules, including the transmitter operation. The host manufacturer 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/warnings as shown in this manual.

Limited module procedures
Not applicable. The module is a Single module and complies with the requirement of FCC Part 15.212.

RF exposure considerations
This module needs to be used on mobile devices located 50cm away from the human body and if RF exposure statement or module layout is changed, then the host product manufacturer is required to take responsibility of the module through a change in FCC ID or new application. The FCC ID of the module cannot be used on the final product. In these circumstances, the host manufacturer will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization.

Antennas
Antenna Specification are as follows:

• Antenna Type : Rob antenna
• Antenna Gain(Peak): 4 dBi (Provided by customer)

This device is intended only for host manufacturers under the following conditions: The transmitter module may not be co-located with any other transmitter or antenna; The module shall be only used with the External antenna(s) that has been originally tested and certified with this module. The antenna must be either permanently attached or employ a ‘unique’ antenna coupler. As long as the conditions above are met, further transmitter tests will not be required. However, the host manufacturer 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.).

Label and compliance information
Host product manufacturers need to provide a physical or e-label stating “Contains FCC ID: 2ABNA-TRM201” With their finished product.

Information on test modes and additional testing requirements

• Radio Technology : UHF
• Operation frequency : 410MHz-470MHz
• Conducted Power : 2W(33±1dBm)
• Channel spacing : 6.25KHz, 12.5KHz, 25KHz
• Modulation type: GMSK
• Antenna Type : Rod antenna, Maximum Gain is 4dBi.

Host manufacturers can contact Guangzhou Geoelectron Science & Technology Company Ltd. to learn how to implement the above function, and how to reproduce the testing mode during certification, if possible, Guangzhou Geoelectron Science & Technology Company Ltd. can supply the certification sample to the host manufacturer. Host manufacturer must perform tests of radiated & conducted emission and spurious emission, etc according to the actual test modes for a stand-alone modular transmitter in a host, as well as for multiple simultaneously transmitting modules or other transmitters in a host product. If no other module is used and no change to this module, the product can only comply with FCC part 15 B to meet the sale requirement. Only when all the test results of test modes comply with FCC requirements, then the end product be sold legally.

Additional testing, Part 15 Subpart B disclaimer
The modular transmitter is only FCC CFR Title 47 Part 90, FCC CFR Title 47 Part 2 that the host product manufacturer is responsible for compliance to any other FCC rules that apply to the host not covered by the modular transmitter grant of certification. If the grantee markets their product as being Part 15 Subpart B compliant (when it also contains unintentional radiator digital circuity), then the grantee shall provide a notice stating that the final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed. 2.10 How to address changes to conditions, operation, and/or restrictions Please refer to the additional section 2.1 of this manual.
