FCC ID: ACTLHL3 To whom it may concern, The materials in this report pertain to a Class II permissive change to the Johnson Controls Homelink® model ACTLHL3. This model was originally certified as a stand-alone module in July of 2003 (EA494510). Later that year the power settings were changed and the model was tested at the vehicle-level in an Acura TL automobile EA504983, August 2003). Per our agreement with the FCC for this test methodology a separate Class II change was filed for use of this model in an additional automobile, the Acura MDX (EA471316). This report covers further changes to power settings for this model; testing is again done at the vehicle level at a 10m distance and is specific to the Acura TL automobile. A separate Class II change will be filed shortly for the Acura MDX automobile. Johnson Controls Interiors has invested considerable resources into developing our Homelink ® products. For this reason we respectfully request that the following items be held as confidential. • Circuit Block Diagrams • Theory of Operation • Schematics The Federal Communications Commission will be notified, in writing of any changes in the software/programming of this device that could affect its RF characteristics.
