American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 June 26, 2003 RE: Icom Incorporated FCC ID: AFJ262700 I have a few comments on the above referenced Application. 1) The explanation regarding compliance 95.193(b) mentions that the ATS tone is a 10 second audible tone. The information in the manual (page 20) states that this signal gets sent automatically every 60 seconds. Since this is automatically generated for 10 seconds every 60 seconds and is audible, it appears that this mode can interfere with the requirement given in 95.193(d). Please provide further information to explain how the ATS function is considered compliant to the rules. For instance, does the unit check for open channel prior to sending the ATS tone, etc. 2) The answer to previous question 4 does not appear to have been addressed. The occupied bandwidth shown in the test report (pages 20 & 21 and reported in 6.8.6) should have been measured to the outside of the emissions sidelobes at the level noted. Please correct.

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 June 27, 2003 RE: Icom Incorporated FCC ID: AFJ262700 I have a few comments on the above referenced Application. 1) Below are proposed grant conditions. Note that according to our procedures, we must evaluate SAR for TX's if certain user to antenna distances exist during expected use and the conducted or EIRP power exceeds certain values. For instance for this particular device, if the conducted or EIRP values are > 128 mW (60/freq) with < 2.5 cm spacing in body worn configurations, SAR must be evaluated. For > 2.5 cm spacing, if the conducted or EIRP values are > 257 mW (120/freq), then SAR must be evaulated. For this radio the conducted power was highest. Assuming up to a 50% duty cycle for PTT radios, the conducted value becomes 50% of 488 mW = 244 mW. This value is just under the 257 mW threshold for devices that meet the 2.5 cm distance. From drawings in the manual, it appears that a 2.5 cm distance will exist between the user and antenna if a belt clip is used. Therefore please confirm if in a body worn confirmation the use of the belt clip provides 2.5 cm spacing from the body by providing a photograph or drawing as appropriate that shows this distance is met. Also, please note that even if the device does meet the 2.5 cm requirement, if the FCC has any concerns during an audit of this application they could still require review of the SAR results (full review of report, calibration information, verification information, photographs, measurement uncertainty, etc.). If the belt clip does not provide the 2.5 cm spacing, SAR results are required to be submitted and reviewed. Please note that review of SAR results are subject to additional review costs. Proposed Grant Conditions: Power Output listed is ERP. This device and its antenna must operate with a separation distance of at least 2.5 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. This device must transmit with an operational-based push-to-talk duty cycle not to exceed 50%. End-users must be provided with specific operating instructions for satisfying RF exposure compliance. 2) FYI. For future applications, please ensure that the occupied bandwidth test measures to the outside lobes of the waveform. Your plots reported 8.85 kHz occupied bandwidth which was measured using the automatic measurement feature of the spectrum analyzer. Carefully evaluation of your plots show that by measuring to the outside lobes yields about 10.2 - 10.4 kHz, which agrees with Carson's Rule of 11.0 kHz. For FCC submittals the occupied bandwidth measurements are typically compared to Carson's Rule to assure that they agree. Also, please note that the FCC has expressed concern for use of the automatic feature when it does not measure to the outside of the lobes. Timothy R.

Hi Mr. Johnson, I will upload the SAR test report to so that we can have the EUT approved with SAR without a restriction of 2.5 cm distance. Please proceed with your SAR assessment ASAP. Thanks. Tri Luu

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 July 9, 2003 RE: Icom Incorporated FCC ID: AFJ262700 I have a few comments on the above referenced Application. This response addresses the SAR report recently uploaded. 1) The FCC ID given throughout the SAR report does not match the information given in the filing. Please adjust. 2) The SAR scans do not appear to have covered the entire antenna area. Scans should have been performed over the whole antenna and device to ensure that no secondary hot spots occurred in these areas. Was this done during prescans? Please explain. 3) Please provide a justification for not providing all SAR plots for each configuration tested on page 54 (i.e. if they had similar SAR distributions, a plot of the highest SAR for each test configuration should be sufficient; otherwise additional plots should be included to document the different SAR distributions – purpose is to identify peak locations relative to device and phantom). 4) The SAR test report should include: a) statement of compliance with FCC RF exposure (§2.1093) b) mobile or portable transmitter device category identified c) test device is production unit or identical prototype (47 CFR §2.908)? d) brief description handset holders 5) The user manual does not appear to contain any specific information regarding SAR compliance. If it is expected that the users manual will be updated for this information, please provide an updated users manual for review. 6) Testing appears to have taken place over a 2 day period (5/12 & 5/13). Note that dipole validation test results for each date of device testing must be provided, but it appears to only have been provide for 5/12. 7) The test date on the cover of the report 5/14 does not appear to match the actual test dates. Please correct. 8) P1528 specifies the use of a phantom @ 450 MHz to be 700x600mm with a thickness of 6.3 mm as shown in table 8.2. FCC information from various training has stipulated L and W at >= 0.6 λ (apprx. 400 mm at 450 MHz) and < 6.5 ± 0.2 mm with < 0.5% sagging. It appears that the phantom used was 2 mm thickness. Please explain how compliance with the sag requirements if the phantom was achieved with only a 2 mm thickness. 9) The calibration of the probe does not appear to have shown boundary effect error measurements or measurement uncertainty issues addressed in its calibration. Please provide this information. 10) Please provide further information regarding the reference dipole (i.e. manufacturer, model, serial, etc.). Also, please provide a plot of return loss data for the dipole used. Is original manufacturer calibration information available? 11) Although the dipole verification may have been performed for 450 MHz, the FCC asks to provide the liquid dielectric parameters measured at device mid-band frequencies as well for each day of testing. 12) It appears as if probe boundary effect compensation was not used (section 5.6.4.4). The FCC has specified that when probe boundary effect compensation is not used the probe tip should be positioned at least half a probe tip diameter from the phantom surface during area and zoom scans. It appears that the closest measurements were made at 4mm (page 60) while the probe diameter is also 4 mm (page 62). Timothy R.

Re: ICOM Incorporated FCC ID: AFJ262700 In reply to your recent questions: 1) The FCC ID given throughout the SAR report does not match the information given in the filing. Please adjust A1) See revised SAR report 2) The SAR scans do not appear to have covered the entire antenna area. Scans should have been performed over the whole antenna and device to ensure that no secondary hot spots occurred in these areas. Was this done during prescans? Please explain. A2) Since the D.U.T. power drift was found to be significant over the time, we need to minimize the scan area in order to minimize the effect. BUT prescan for the entire D.U.T. was performed prior to the series of scans in order to identify the hot spot and to check the existence of the second peak as well. 3) Please provide a justification for not providing all SAR plots for each configuration tested on page 54 (i.e. if they had similar SAR distributions, a plot of the highest SAR for each test configuration should be sufficient; otherwise additional plots should be included to document the different SAR distributions - purpose is to identify peak locations relative to device and phantom). A3) In our previous report formats, we used to include all the plots and test results into our test reports. But it happened to increase the size of test report unnecessarily in a certain case where the number of combinations of test configurations resulted in many prescans (multiplying by number of frequencies sometime resulted in more than a hundred scans). As a result we had changed our report format so that we reported the complete set of results and plots for the worst case configuration and only the SAR number for prescans as long as the distributions are similar among them (only accessories were permutated), the FCC and other TCBs have accepted all of our applications in this manner. 4) The SAR test report should include: a) statement of compliance with FCC RF exposure (?.1093) b) mobile or portable transmitter device category identified c) test device is production unit or identical prototype (47 CFR ?.908)? d) brief description handset holders A4) a) See certificate b) See certificate and page 4; Portable c) See page 5; Production unit d) See page 47; The handset holders is mainly made of PVC and contains no metallic component at all in order to minimize field perturbation. Velcro and elastic band were used to attach the DUT on the plate of handset holder. 5) The user manual does not appear to contain any specific information regarding SAR compliance. If it is expected that the users manual will be updated for this information, please provide an updated users manual for review. A5) See revised user manual. 6) Testing appears to have taken place over a 2 day period (5/12 & 5/13). Note that dipole validation test results for each date of device testing must be provided, but it appears to only have been provide for 5/12. A6) Dipole verification can only be carried out on brain tissue since there are no target validation values for muscle tissue. This being the case, the dipole validation must first be carried out on the brain tissue even though that is not the tissue being measured. It is then required to change the tissue in the phantom to body tissue to carry out the SAR measurements. The dipole validation can take 1/2 day to perform with the tissue change out so it becomes impractical at this point in time to carry it out daily. This will change as soon as the IEEE SCC34-2 committee provides dipole validation targets for muscle tissue. As such, the FCC and the other TCB's have not been identifying this to us as an issue. 7) The test date on the cover of the report 5/14 does not appear to match the actual test dates. Please correct. A7) See revised report 8) P1528 specifies the use of a phantom @ 450 MHz to be 700x600mm with a thickness of 6.3 mm as shown in table 8.2. FCC information from various training has stipulated L and W at >= 0.6 ?(apprx. 400 mm at 450 MHz) and < 6.5 ?0.2 mm with < 0.5% sagging. It appears that the phantom used was 2 mm thickness. Please explain how compliance with the sag requirements if the phantom was achieved with only a 2 mm thickness. A8) The flat phantom we employ is designed to have Plexiglas supports inserted lengthwise on either side of the dipole so that the only unsupported portion of the 2mm base is a small section surrounding the dipole antenna. The width of the unsupported bottom is only a couple of cm so the sag from the unsupported section is still well within the requirements of the P1528 standard. 9) The calibration of the probe does not appear to have shown boundary effect error measurements or measurement uncertainty issues addressed in its calibration. Please provide this information. A9) Below 1GHz, thermal calibration is used and care is taken to position the dipole sensors at least on probe diameter away (4mm). In our procedure, we use 6mm displacement to ensure there is no boundary effect compensation required in the thermal calibration. Boundary effect compensation is only required when the probe come closer than 1/2 probe diameter (2mm) with the phantom surface. 10) Please provide further information regarding the reference dipole (i.e. manufacturer, model, serial, etc.). Also, please provide a plot of return loss data for the dipole used. Is original manufacturer calibration information available? A10) The reference dipole was manufactured by UltraTech Labs. according to the guideline on Annex G in IEEE P1528/D1.2, April 21, 2003 standard and Table on pp 47~48 in OET 65 supplement C edition 01-01. Refer to the attached plot of return loss for the dipole used. 450 MHz verification dipole Manufacturer : UltraTech Labs. Model Number : W450 Serial Number : UT-VDP-002-052003 11) Although the dipole verification may have been performed for 450 MHz, the FCC asks to provide the liquid dielectric parameters measured at device mid-band frequencies as well for each day of testing.
