However, based upon our review of this application we have additional questions: 1. Question 3 from previous letter: Please specify the model number, brand, and gain of tested and approved antenna only. No answer was provided for this request. 2. Question 6 from previous letter: I understand that the model XCRF-600 transmits without modulation to the tag. If so, the XCRF-600 does not satisfy the requirement of a 2.1. Please explain the purpose of the modulated signal after the tag is activated. The FCC requires that the system does NOT employs useless modulation (information not written to, or read from the passive tag) just to comply with paragraph (a)(1) transmit/receive bandwidth requirement, does not meet the intent of Section 2.1. The reader must be able to write to, and read information from, the passive tag. Please explain and confirm the above. 3. Question 9 from previous letter: RF exposure exhibit per part 15.247(b)(5): Please provide the actual separation distance required to satisfy compliance with the FCC RF exposure requirements. The calculated distance must be included with the Professional Installer’s installation instructions as such: “WARNING: FCC RF Exposure Requirements: The antenna(s) used for this transmitter must be installed to provide a separation distance of at least xxx cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter.” For your info - Please note that the FCC requires that we list the required separation distance on the Grant of Equipment Authorization. file:///U|/S/SHENZ_TQ4/2200CC5/cust%20reply%20-%2051109.htm (3 of 4)11/10/2005 5:49:04 AM
