Box 358315 Pittsburgh, PA 15251-5315 Re:Applicant:Itronix Corporation Product:T5200 Handheld PC FCC ID:KBCT5200RIM 731 Confirmation #:EA94542 Correspondence Ref. #9394 Gentlemen: Pursuant to e-mail from your Frank Coperich to Richard Sargent of Itronix on Thursday, August 26, 1999 6:07 AM, which was subsequently forwarded to myself at APREL Laboratories on Tuesday, August 31, 1999 12:34 PM, here are APREL Laboratories’ responses. To simplify cross-referencing these to the original comments I am including the August 26 th e- mail from Frank Coperich to Richard Sargent below, with comments: To:Richard Sargent, null From:Frank Coperich ... Date of Original E-Mail:08/26/1999 1.) This application is incomplete. Please submit all of the information required by Section 2.933 of the Commission's R&R. (To be addressed by Itronix) 2.) This unit uses a RIM (Research in Motion) module, EAS 83666 that was approved for 2.4 W at the antenna terminal for meeting mobile MPE limits. Itronix is filing SAR to use this module with a laptop computer, requesting 2 W conducted output. I believe most of RIM's modules have a fixed peak output, the requested 2 W needs to be confirmed. The current filing also uses an integrated antenna, is ERP needed or can we go with conducted? The RIM R900M-2-O modules (EAS83666) have a fixed 2 Watt output. The revised SAR report (ITRB-T5200 R900M2O-3190&3301) attached, in PDF format, includes scaling of the results from the nominal 2W to the 2.4W worst case (this accounts for the 1dB QA uncertainty that RIM determined existed at that time for their output power determination in production.) ERP measurements were also performed and the pertinent report (ITRB-T5200 R900M2O-3303) is attached in PDF format. The maximum ERP measured was 2.2W (33.5dBm). 3.) They need to upload another copy of the SAR report. The plots are not * Consulting * Research * Training * Certification Testing Since 1981 51 Spectrum Waytel: (613) 820-2730 Nepean, Ontariovisit our Web Pages: www.aprel.comfax: (613) 820-4161 Canada K2R 1E6email: [email protected] readable due to scanning of rather dark copies of the original report. The attached PDF version of the SAR report should rectify this problem. 4.) Based on information that can be read from the SAR report, the following should be clarified or incorporated into the SAR report that will be subsequently uploaded (a) The device was tested using a duty factor of 45.45% but SAR compliance was based on a 100% duty factor by extrapolation. If the device will be used at 100% duty factor, it needs to be tested at 100% duty factor. Otherwise, it will be approved at 45.45% duty factor, or lower is applicable and supportable by the data. Please also clarify if any duty factor was allowed on the original RIM approval. The firmware in the test sample limits the on time to 5 minutes which made the performance of area scans at 100% impractical, and made zoom scans onerous. We have since improved out data gathering routines to allow us to perform each zoom scan in less than 5 minutes. The SAR report has been rewritten to include the 100% data in the determination of the maximum 1g SAR. No duty factor was allowed in the original RIM approval (confirmed with RIM’s Masud Attayi on 28 Sept. 1999). (b) The highest SAR values on the curves in figures 9 and 10 are inconsistent with the values reported in section 6.2 of the SAR report, more clarification is needed to determine how these numbers support each other. Figure 10 of the original SAR report is a version in which the separation vs SAR data has been scaled up to 100%. The revised report including the 100% zoom and depth measurements resolve these inconsistencies. (c) In the last table in section 6.2(5), the frequency appears to be in error. You are correct – the correct frequency is 896MHz. (d) The 1-g averaging in section 6.2(6) appears low compared to the 4.064 W/kg peak SAR indicated in 6.2(5), please clarify (also check figures 9 and 10). See the revised report which incorporates 100% duty factor data. In the original report the 1-g average SAR reported was for a 27mm separation while the 4.064 W/kg peak SAR was obtained with an 11mm separation. In addition, these two values and figure 9 are for a 45.45% duty factor, while figure 10 was scaled up to 100%. (e) This device has a rotatable antenna. The picture in the report is not clear on the antenna setup during the SAR tests, its orientation with respect to the device (laptop) and the phantom. Does the test position cover worst case exposure with respect to the allowable operating positions of the antenna? The antenna mount is designed to allow the antenna to rotated through 90° in a plane perpendicular to the keyboard. The antenna’s intended transmitting position is vertical and its storage position is folded horizontally on top of the folded display (see pictures in Appendix * Consulting * Research * Training * Certification Testing Since 1981 51 Spectrum Waytel: (613) 820-2730 Nepean, Ontariovisit our Web Pages: www.aprel.comfax: (613) 820-4161 Canada K2R 1E6email: [email protected] B of the SAR report). Therefore, the test position did cover the worst case exposure with respect to the allowable operation positions of the antenna. Thank you for your cooperation, Sincerely, Paul G.

Test Facility The tests were performed for Itronix Corporation by APREL Laboratories at APREL’s EMI facility located in Nepean, Ontario, Canada. The laboratory operates an (3m and 10m) Open Area Test Site (OATS). The measurement facility is calibrated in accordance with ANSI C63.4-1992. A description of the measurement facility in accordance with the radiated and AC line conducted test site criteria per ANSI C63.4-1992 is on file with the Federal Communications Commission and is in compliance with the requirements of Section 2.948 of the Commissions rules and regulations. APREL’s registration number is 31040/SIT (1300F2) APREL is accredited by Standard Council of Canada, under NAPTO program (ISO Guide 25). APREL is also accredited by Industry Canada (formerly DOC) and recognised by the Federal Communications Commissions (FCC). Standard The evaluation and analysis were conducted in accordance with FCC Rules and Regulations Parts 2.1046 and the appropriate limits. Test Equipment The test equipment used during the evaluation is listed in Appendix A. Calibration of all test equipment’s are performed at 12 months intervals. All equipment used is calibrated or verified in accordance with the intent of AQAP-6/MIL-STD-45662. Environmental Conditions Measurements were conducted in open area test site. - Temperature:18 °C ± 2 - Relative Humidity:30 - 50 % - Air Pressure:101 kPa ± 3 October 4, 1999 Page 6APREL Project No.: ITRB-T5200 R900M20-3303 Consulting * Research * Training * Certification Testing Since 1981 Itronix Corporation TEST RESULTS FOR Effective Radiated Power (ERP) of Handheld PC T5200 with a Research in Motion R900M-2-0 transmitter October 4, 1999 Page 7APREL Project No.: ITRB-T5200 R900M20-3303 Consulting * Research * Training * Certification Testing Since 1981 Test:RF Power Output as Radiated (ERP) Ref.:FCC Part 2 paragraph 2.1046 Criteria:N/A Set-up:See Figure No. 1. Equipment:See Appendix A. Procedure:RF Power Measurement by Radiated Method (ERP): Test site: The radiated RF power measurement was taken at APREL Laboratory’s open area test site (OATS). This open area test site is calibrated to ANSI C63.4 document and a description of the measurement facility is on file with the Federal Communications Commission and is in compliance with the requirement of Section 2.948 of the Commissions rules and regulations.(FCC File No.: 31040/SIT) The test was set-up as illustrated in Fig.1. The handheld PC was configured to operate at maximum power with carrier unmodulated.. The equipment under test was placed on a turntable positioned 3 meters away from the calibrated receiving antenna, which in turn was connected to the spectrum analyzer. For each transmitter frequency, the received signal was maximised by rotating the turntable and adjusting the height of the receiving antenna. To obtain the actual ERP, the handheld PC was replaced by a half-wave vertically polarised antenna, RF power amplifier and signal generator. The center of the dipole antenna was placed in the same location as the handheld PC. The signal generator level was adjusted until the reading on the spectrum analyzer was identical to that obtained when the handheld PC was on the turntable. The output of power amplifier was disconnected from the dipole and connected to an RF power meter. The effective radiated power was read directly form the power meter. The process was repeated for two more channels. Results: . See Table 1 October 4, 1999 Page 8APREL Project No.: ITRB-T5200…
