We added comments about that i nto page 5 and 10. 5) The relative measurements were performed on the fundamental and spurious emissions with each condition of key folded and key set up. The key set-up condition was worse case under both fundamental and spurious emissions, we, therefore, tested while the key was set up. We commented that in the test report, page 5. 6) Please check the attached file which is from DENSO. 7) The result of the measurement >1GHz from PK detector, PBW: 1MHz, VBW: 1 MHz, had satisfied the average limit, so the average measurement was not necessary. We corrected the data, and we deleted the data measured by average detectors. 8) We have revised it. Kanako Sanda A-Pex Int ernational Co., Ltd.

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 November 30, 2001 RE: Denso Corporation FCC ID: HYQ12BBM After a review of the submitted information, I have a few comments on the above referenced Application. 1) All files uploaded for the block diagram exhibit were empty. Please resubmit these exhibits. 2) Please upload Exhibits for the Operational Description, Labeling Information, and Users Manual. 3) The schematic contains several parts that reference a component listing which was not provided. Please provide this. 4) Portable devices should be tested while positioned in each of all 3 axis. No information was presented in the photographs or test report regarding this issue. Please comment. 5) The test report stated that the key folding condition (key folded vs. key set up) was investigated and the worse case position (key set up) was used. We have seen devices where the worse case for the fundamental may be one condition, while for the spurious emissions may be worse under a different condition. Please confirm if the key condition was investigated for both the fundamental and spurious emissions and that the worse case for both the fundamental and spurious was the same condition. 6) Please provide information to show compliance with 15.231 (a)(1). 7) Due to the type of emissions created, many of these types of devices can not be measured using average detectors (> 1 GHz), but must instead be corrected mathematically by a duty cycle. Please comment on the use of the 10 Hz VBW for average measurements. 8) FYI, It appears that the measurements uncertainty boxes are not correctly checked in the test report. Timothy R.

1 3.Outline of the system 3.1 Description of the system operation This system is mainly used for locking or unlocking the doors of the vehicle. The transmitter sends a radio wave signal while the button is pushed. The receiver becomes active in response to the signal from the transmitter. 3.2 Transmitter The transmitter sends a signal using radio frequency. The transmitter emits the radio frequency while the button is depressed. If the button is depressed continuously, then the transmitter will only send a signal for a predetermined constant time (For example 5 seconds. This is an auto-power-off feature)

The sequence is used: Operation Mode : Transmitting 2.4 Test Procedure Tabletop Equipment Radiated Emissions EUT was placed on a platform of nominal size, 1m by 1m, raised 80cm above the conducting ground plane. Test was made with the antenna positioned in both the horizontal and vertical planes of polarization. The measurement antenna was varied in height above the conducting ground plane to obtain the maximum signal strength. The measurement distance was 3m. Preliminary Radiated Emissions Tests were performed before Final Radiated Emissions Measurements as follows; -The noise was measured at each position of all three axes X, Y and Z to compare the level, and the maximum noise occurred at the position showed in the photograph. -The relative measurements were performed on the fundamental and the spurious emissions with each condition of the key folded and the key set up. The key set-up condition was worse case under both the fundamental and the spurious emissions, we, therefore, tested while the key was set up. See the photograph.
