ADT (Shanghai) Corporation 2F, Building C, No.1618, Yishan Rd., 201103, Shanghai, China Feb. 14, 2006 FCC ID: RG3WGPS900M01 The following lists are the answers for the comments on Feb. 11, 2006, please kindly have a review on it: 1) Information on the 731 cites a frequency range of 902.1 – 925.62 MHz and the test report shows 902.1 – 925.6 MHz (pages 5, 7, & 8) and test of 79 channels (902.1 – 925.58 MHz). The frequency list provided cites 902.0964 – 925.50504 MHz. What is correct? Please correct all affected exhibits as necessary. RE: The actual frequency range is correct that is 902.1 – 925.62 MHz. And should the client need to improve the documents that contain the information of frequency? The test report that shows the frequency range has all been changed with actual one. 2) This application should also include an appropriate RF exposure exhibit if the device is approved under 15.247. See attached example which would likely apply in this case. RE: Would you allow me to upload this tomorrow since it has not been come out yet. 3) Information in the test report (section 4.9), operational description, and users manual mention using an SMA-K joint connector. I am not familiar with “SMA-K” connector and can not seem to easily find information on the internet regarding what this is. However it appears to possibly be a standard type SMA connector. This would not be in compliance with 15.203. To meet the FCC requirements of 15.203, this would need to be reverse-polarity or reverse-sex connector. Please provide further information as necessary. Also, this may require updating affected exhibits to clarify as well. RE: It is dealt by mail already and please see the antenna photo. 4) Specific information on how the 15.247 TX meets several requirements has not been provided. Frequency Hopping Systems approved under 15.247 require detailed theory of operation to cover the following information below. For instance, a) is not simply answered with “random”. A sample pseudo-random list that would actually be generated needs to be provided or complete detail on how the list is generated. RE: The latest explanations have been sent by mail on 16:03, Feb. 14, 2006. Is there any other document needed to submit? 5) ~ 13) RE: Please see the test report. 14) & 15) RE: There are questions from our engineers which sent by mail on 16:31, Feb. 14, 2006.

Dear Tim, Thank you. I'll add these when next upload. As to the frequency, there are new explanations. Due to its technicality, I translate it and also ask the client to translate one version in order to reduce the confusions that may occur within a minimum level. My version: The hopping is pseudorandomly. ME T HO D : As soon as the system is powered on, a random figure is produced (less than 50). This figure moves left for one time within each transmission (eliminating the used channel). Compared with the eliminated channel, if the channel which moves left is more than 50 or minuses 1 by the used channel, after all 50 channels are used, the channels are reset. Thus the system runs this procedure periodically, and when the receiver receives synchro-data it also begins to hop synchronically. If the receiver does not receive synchro-data then it may wait in the random channel. The client's version: Hopping frequency is changed to pseudo randomly hopping frequency. It will produce random data (less than or equal to 50) when RF system is powered on. The channel will move left once when transmitting once (except used channel). If new channel data(after left move) is more than 50 or equal to used channel, then this data will be decreased 1 until new channel data is not equal to used channel. After using up 50 channels, the channel indicator will be cleared as 0 and continue to the above process. Receiver starts to synchronized hopping frequency when receiving synchro data. If it does not receive the data, it will be waiting in the random channel. Transmitter sends the channel information of next hopping frequency when transmitting. Receiver will send back ACK and move to next channel defined by transmitter. Dear Major & Jerry, Here I attach the Chinese version. Please do me a favor when the confusions come up due to something that not translated well.  è°ƒé¢‘æ› ́改: 改ä ̧ºä¼ªéš 机跳频.  æ-¹æ³•,ä ̧Šç”μ开始系统产生ä ̧€ä ̧ªçœŸéš 机数(å° äºŽç-‰äºŽ50),æ ̄ å ‘å°„ä ̧€æ¬¡å·¦ç§»ä ̧€  次(å‰”é™¤å·²ç» ä½¿ç” ̈ä¿¡é “).æ ̄”è¾ƒå‰ƒé™¤ä¿¡é “,å¦‚æžœå·¦ç§»å¾—å‡ºçš„ä¿¡é “å¤§äºŽ50æ  ˆ-è€...æ ̃ ̄ä»¥ä½¿ç” ̈çš„ä¿¡é “è¿™è¿™ä ̧ªæ•°å‡ 1,50ä ̧ªä¿¡é “éƒ½ä½¿ç” ̈å Ž,ä¿¡é “ä½¿ç” ̈æ ‡å¿—  æ ̧...零.å ‘å°„ä ̧€æ¬¡å·¦ç§»ä ̧€æ¬¡(å‰”é™¤å·²ç» ä½¿ç” ̈ä¿¡é “).æ ̄”è¾ƒå‰ƒé™¤ä¿¡é “,å¦‚æžœå·¦ç§  »å¾—å‡ºçš„ä¿¡é “å¤§äºŽ50æˆ-è€...æ ̃ ̄ä»¥ä½¿ç” ̈çš„ä¿¡é “è¿™è¿™ä ̧ªæ•°å‡ 1.如æ-¤å¾ªçŽ ̄,接  æ”¶æœºåœ ̈æ”¶åˆ°å Œæ-¥æ•°æ ®å Žå¼€å§‹å Œæ-¥è·³é¢‘.å¦‚æžœæ²¡æœ‰æ”¶åˆ°å Œæ-¥åˆ™åœ  ̈éš æœºä¿¡é “ç-‰å¾....

Dear Tim ， The explanation s of the hopping is as following: It will produce a random data (less than or equal to 50) when the RF system is powered on. The channels will move left for one time within each transmission ( See note below)(eliminating the used channel). Compared with the eliminated channel, if the new channel data (after left move) is more than 50 or equal to the used channel, then this data will be decreased 1 (If it meets the used channel then it will continue to minus 1 until the new channel data is not equal to the used one). After using up 50 channels, the channel indicator will be reset and continue to the above process. Hopping frequency is changed to pseudo randomly hopping frequency. The method is as below: Note: Our understanding of the sentence that marked red is as below: The 8 bit binary register which contains the channel number will shift left by one bit and then produce one channel number as the next channel number. Hopping frequency is changed to pseudo randomly hopping frequency. The method is as below: Where: A: the previous channel number B: the next channel number Firstly, A+A=B Secondly, If B=<50, when B is not used, B is the next channel number; If B > 50, B = B-1 until B=<50 Example code(binary) channel number (HEX) channel note 110001 31 49 NA 100010 22 34 NA 000100 4 4 NA 001000 8 8 NA 010000 10 16 NA 100000 20 32 NA 000000 0 0 NA Best wishes ※※※※※※※※※※※※※※※※※※※※ ADT (Shanghai) Corporation 2F , C Building, No.1618, Yi Shan Rd., Shanghai,China Lily Liu 110000 30 48 000000 → 111111(0-1=111111) 111111channel number(HEX)=3F>31 so next code is 110000=30(HEX) 011111 1F 20 110000 → 100000(have used) 100000-000001=011111=1F(HEX) ......
