**When the product is small, labelling in the manual only is allowed (labeling on the device is not required). Please include the following warnings in the device installation manual:

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 Changes or modifications not expressly approved by the party responsible for compliance could void the users authority to operate the equipment. This transmitter must not be co-located or operated in conjunction with any other antenna or transmitter. When installing the device in mobile equipment, please describe the following warning in the installation manual:

This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment and meets the FCC radio frequency (RF) Exposure Guidelines. This equipment should be installed and operated keeping the radiator at least 20cm or more away from persons body. When installing the device in portable equipment:

It is necessary to conduct a SAR test with your set mounting this module. Class II permissive change application is necessary using the SAR report. Note:

Portable equipment: Equipment used where the space between the human body and antenna are within 20 cm. Mobile equipment: Equipment used where the space between the human body and antenna exceed 20cm. This device is intended only for OEM integrators under the following conditions:

1) The antenna must be installed such that 20 cm is maintained between the antenna and users, and 2) The transmitter module may not be co-located with any other transmitter or antenna. 3) The use of an antenna with gain less than 1.4 dBi. Copyright 2017, Izotope Confidential January 30, 2017 As long as the 3 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 IMPORTANT NOTE:

In the event that these conditions cannot 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 cannot 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 This transmitter module is authorized only for use in device where the antenna may be installed such that 20 cm may be maintained between the antenna and users. The final end product must be labeled in a visible area with the following: Contains FCC ID:XXXXXXXXXX. The grantee's FCC ID can be used only when all FCC compliance requirements are met. Manual Information To the End User The OEM integrator should not provide information to the end user regarding how to install or remove this RF module in the users 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. Copyright 2017, Izotope Confidential January 30, 2017

FCC ID: 2AKPU1DX Description of Permissive Change The report is prepared for a second FCC Class II permissive change. This current permissive change (for product model number SP121) report is prepared for a FCC Class II permissive change. The differences compared with the original report is declaring the antenna gain from the average value -2.3 dBi to peak value of +4.5 dBi. The antenna type is changed from the original PCB trace antenna to a chip antenna (Johanson part number 2450AT18D0100E). The 1DX module is tested in the host Spire model number SP121 in the application.

(The previous permissive change (for product model number SP111) report had a difference compared with the original report by declaring the antenna gain from the average value 1.4 dBi to peak value of 4 dBi. The antenna type was still the same Monopole PCB trace antenna. The 1DX module was tested in the host Spire model number SP111 in the application) Please refer to the test reports for the current permissive change (SP121) for more details about the current test items.
