January 8, 2006 American TCB 6731 Whittier Ave Suite C110 McLean, VA 22101 USA Subject: Request for confidentiality for the functional stimulation device (control unit) transceiver, model name CU, FCC ID:TVF-L300-CU-V10 Dear Gentlemen, In regards the exhibits submitted in support of the application for certification, please classify the following as confidential under the provision of 47 CFR 0.459: 1) Schematic diagram, files “Schematics_CU_16732 “(1 page). The above material contains trade secrets or technical data which NESS Ltd. deems to be proprietary. Therefore this information would customarily be guarded from competitors and cannot be accessible to the general public

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 January 11, 2006 RE: NESS Ltd. FCC ID: TVF-L300-CU-V10 After a review of the submitted information for FCC, I have a few comments on the above referenced Application. 1) Please provide a clear photograph of the back of the board containing the TX. The current photos do not appear to be clear. 2) This is a portable device, but it is uncertain if it was tested in all 3 axis in effort to obtain worse case radiated measurements (power and spurious). Please review. 3) Please provide the manufacturers declaration for duty cycle as referenced in the test report that justifies appropriate duty factors applied. Where possible, the FCC also wants measured data to show theory is correct. 4) Users manual appears to be missing information required by 15.21. Please review/correct as necessary. 5) FYI....Under 15.247, it is recommended to provide an RF exposure exhibit regardless of output power. Please see attached as an example. 6) FYI....The spectral density should normally be calculated for 15.247 in cases where this may not be done at the antenna connector (see attached document). However given the power is < the spectral density limit, the spectral density will also be in compliance and we are therefore not requiring this to be retested. Timothy R. Johnson 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. Also, please note that partial responses increase processing time and should not be submitted. Any questions about the content of this correspondence should be directed to the sender.

FCC ID:TVF-L300-CU-V10 Date: January 2006 RF_exposure_16732_CU_rev1.doc Page 1 of 1 RF exposure evaluation according to FCC CFR 47 part 15, §15.247(i) The control unit is a portable device. No SAR evaluation required if a transmitter power is below the following threshold: Tunable range, GHz Flow Fhigh Operating frequency, GHz 60/f SAR limitation, mW 2.400 2.483 2.433 24.66 Maximum measured transmitter power: Pout conducted, mW Maximum antenna gain, dBi Pout EIRP, mW 0.95 1.5 1.34 Threshold for no SAR evaluation is 24.66 mW, maximum measured Tx power is 0.95 mW – conducted and 1.34 mW- EIRP. Conclusion: No SAR evaluation is required since the maximum transmitter output power, both conducted and radiated, is below FCC threshold.
