Type of Confidentiality RequestedExhibit ShortTermPermanentBlockDiagrams ShortTermExternalPhotos ShortTermPermanent* 1 InternalPhotos ShortTermPermanentOperationDescription ShortTermPermanentBOM ShortTermPermanentSchematics ShortTermTestSetupPhotos ShortTermPermanent*User’sManual *Note: ______(Insert Explanation as Necessary)______ ___Quectel Wireless Solutions Company Limited _has spent substantial effort in developing this product and it is one of the first of its kind in industry. Having the subject information easily available to "competition" would negate the advantage they have achieved by developing this product. Not protecting the details of the design will result in financial hardship. Permanent Confidentiality: The applicant requests the exhibits listed above as permanently confidential be permanently withheld from public review due to materials that contain trade secrets and proprietary information not customarily released to the public. Short-Term Confidentiality: The applicant requests the exhibits selected above as short term confidential be withheld from public view for a period of ____ days from the date of the Grant of Equipment Authorization and prior to marketing. This is to avoid premature release of sensitive information prior to marketing or release of the product to the public. Applicant is also aware that they are responsible to notify TCB in the event information regarding the product or the product is made available to the public. TCB will then release the documents listed above for public disclosure pursuant to FCC Public Notice DA 04-1705.
