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. FCC Caution: Any changes or modifications not expressly approved by Logpro Ltd. could void the user's authority to operate this equipment. This transmitter module is authorized to be used in other devices only by OEM. Further transmitter testing 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.). 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 manual of the end product. Note that this product is NOT a Software Defined Radio in the sense that it is not possible in any way to make any changes to the RF transmission characteristics via software that would cause non compliant behavior. The antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter except in accordance with FCC multi-transmitter product procedures.
