Per your request, I uploaded the block diagram with info. of spread spectrum system. And Lionda just emailed us the information below: Here is the information for spread spectrum system: 1. Spread Rate: 32-chip per symbol. 2. Data rate per symbol: 3-bit / symbol 3. Average chip per data bit: 32 (chip / symbol) / 3 (bit / symbol) = 10.667 4. Symbol rate at 19.2MHz master clock: 23.4 us (microsecond) per symbol. 5. Spread Spectrum method: FSK modulation 6. Chip rate: 1.366Mbps 7. Voice Coding: ADPCM Please let me know if there is anything else you need. Thank you!

My mother in law passed yesterday and it was most important to take care of my wife first. Please look at the definition of a spread spectrum system under Section 2.1 of the Rules. In it's simplest form, your device takes a voice signal, converts it to relatively slow data rate signal, and then logically sums it with a much faster data rate. The chip rate is the ratio between the slow speed data and the high speed spreading data. Please provide information on your slow speed data rate, and the chip rate. If a block diagram can be provided illustrating the spreading function, this would also be welcomed.

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 December 4, 2002 RE: Lionda Technology FCC ID: O63GH9762DLD02 I have a few comments on this Application. 1.) Please provide a description of how this device meets the definition of a Spread Spectrum system as defined in Part 2.1 of the Rules. It is unclear if I am examining a Direct Sequence or Frequency Hopping system. If this is a hopper, a listing of the hop sequence is required. If this is a direct sequence system a description of the chip rate would be helpful. 2.) Please provide a required circuit description. None has been provided as of this writing. 3.) Does this equipment have “constant envelope” emissions? In other words, does the modulation envelope change over variations of input audio tones and/or input audio amplitude? 4.) The RF Exposure comment as listed on pp. 17 of the Test Report is inappropriate for a low power device such as this. Please revise. 5.) There is no RF Exposure warning contained in the Manual. Please correct. 6.) Please provide RF Exposure estimation. 7.) Please provide a conducted as well as a radiated RF Pout measurement. Please describe the power as peak or average as appropriate. If any time averaging is utilized, please report the duty cycle. Thanks, William H. Graff President and Examining Engineer mailto: [email protected] The items indicated above must be submitted before processing can continue on the above referenced application. Failure to provide the requested information may result in application termination. Correspondence should be considered part of the permanent submission and may be viewed from the Internet after a Grant of Equipment Authorization is issued. Please do not respond to this correspondence using the email reply button. In order for your response to be processed expeditiously, you must submit your documents through the AmericanTCB.com website.
