Columbia, MD 21046 Fax: (310) 344-2050 Reference FCC ID: HBW1889 Organization: The Chamberlain Group Inc. Request under 47 CFR 0.459 that materials submitted to the commission be withheld from public inspection. The Chamberlain Group Inc. hereby requests that the materials attached here to be withheld from public inspection in accordance with 47 CFR 47 0.459. Specifically, The Chamberlain Group Inc. requests that the following materials be withheld from public inspection under 47 CFR 0.459 because the schematics and designs are considered confidential trade secrets and technical data which customarily would be guarded from competitors: Schematic, Block Diagram and Theory of Operation. Therefore, in accordance with CFR 47 0.459, The Chamberlain Group Inc. requests that the above listed materials, copies of which are here, to be withheld from public inspection. We also ask that the above information be withheld from the OEM incorporating this module into his design. Authorized Signature: Date: 05/26/2004 Barbara P.

Appendix A contains test photos, and Appendix B contains original test data. The data contained in this report reflects only the items tested in the configurations and mode of operations described. An attempt has been made to arrange the EUT, with the equipment provided, into a test configuration which maximizes the observed emissions of the EUT while simulating, as close as practical, a typical end-use installation.

DUTY_CYCLE_BILL.doc This is the billion code modulation duty cycle calculation. Refer to FCC 47 CFR Ch. 1 (10-1-02 Edition ) Page 691.

Each digit starts with an OFF mS. 1 mS/bit Could be all OFF 0 mS ON 4 mS OFF Could be 1 ON 1 mS ON 3 mS OFF Could be 2 ON 2 mS ON 2 mS OFF Could be 3 ON 3 mS ON 1 mS OFF (WORST CASE) This calculation has all bits ON for each digit (WORST CASE). This would rarely happen in a transmitter because all ON for the digits would be an unrealistic transmitter code.
