Ref: Declaration of Class 2 Permissive Change to original model FCC: Q639575N



Dear Sir or Madam,

This letter is to advise that the new model 9575E is derivative of the original model 9575N. The
principal changes to the 9575N design are:

    1. Modification to the Application Board with the addition of an FPGA in order to add support
       for an external processing module.
    2. Changes to the SIM Connector Board to support connections to the external processing
       module and new battery design.
    3. Changes to the form-factor and casing.
    4. New battery design.
It should be noted that the transmitter performance and functionality is not affected by these
changes and that the changes to the PCB layout have been kept to a minimum.

A detailed list of changes to the 9575N design and a description of the regulatory testing carried out
on the 9575E can be found in the attached document [ P2689-REGA-015 ‘9575N to 9575E Change
Description’].

Yours sincerely,




Hermon Pon
