No. 2, Innovation Road II, Hsinchu Science Park, Hsinchu 300, Taiwan Tel: 886-3-5780211 ; Fax: 886-3-5776598 Date: 1/3/2024 FCC Laboratory 7435 Oakland Mills Rd Columbia MD 21046 SUBJECT: Class II Permissive Change for FCC ID: TX2-RTL8852CE The intention of this application is to enable the modular FCC ID: TX2-RTL8852CE, granted on 11/21/2022 to be integrated in Lenovo Notebook Computer ThinkBook 14 2-in-1 G4 IML. U-NII-4 feature is disabled by embedded software and cannot enabled/overridden by users via any other mean. The module installed into host platform mentioned above is electronically and mechanically identical to the original certified module. The Original FCC testing on module under FCC ID: TX2-RTL8852CE was performed with an antenna of higher gain, and the antenna was connected to the module in an open environment. The current host platform under application uses an antenna of the same type but of lower gain and is installed inside the host platform enclosure. The physical restraints introduced by the host platform should have resulted in equal or lower level of radiated emission. Therefore, additional Radiated emission testing is not necessary. Software security remains unchanged from the original application. Except for the change above, the design, hardware and implementation are exactly same with original. Sincerely yours, Dana Liaw danaliaw@realtek.com

(original Grant date: 11/21/2022) Dear Examiner, This is to request a class II permissive change for 11ax RTL8852CE Combo module, Model Name: RTL8852CE, FCC ID: TX2-RTL8852CE. The Major change filed under this application is:

The subject approved module is being used in a specific host(portable category configuration: notebook computer, Brand Name: Lenovo, Model Name:

IdeaPad 5 2-in-1 16AHP9. SAR testing is performed to demonstrate compliance. The host antenna has the same type as originally approved with lower gains in the intentional transmit frequency bands, RF output power has been reduced from the original filing and therefore radiated performance in the intentional frequency bands is expected to be lower than that measured in the original modular approval. Beamforming mode was turned off. Software security remains unchanged from the original application. Please kindly review the application documents submitted and grant approval for this Permissive Change application.
