FCC compliance statement This equipment has been tested to be found to comply with the limits for class A digital device, pursuant to Part 15 of the FCC Rules. Operation is subject to the following conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Class A limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • Reorient or relocate the receiving antenna. • Increase the separation between the equipment and the receiver. • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. • Consult your dealer or an experienced technician for help.

Equipment:Wireless Point of Sale Terminal with a Research in Motion R802D-2-O Radio Modem (DataTAC / Ardis network) Model:Nurit 3010, Data TAC / Ardis Standard:FCC 96 –326, Guidelines for Evaluating the Environmental Effects of Radio- Frequency Radiation ENGINEERING SUMMARY This report contains the results of the engineering evaluation performed on a Lipman Nurit 3010 wireless point of sale terminal (POS) operating with a built-in Research in Motion R802-2-D DataTAC/Ardis radio modem. This report is supplementary to the engineering evaluation for bystander exposure, report LPMB-Nurit 3010 DataTAC-3516B. The measurements were carried out in accordance with FCC 96-326. The POS was evaluated at its nominal maximum power level (2W / 33dBm). The duty factor of the production R802D- 2-O modems will be controlled to be intrinsically restricted to 25% (see Appendix F). For the SAR Analysis for the User, the Lipman Nurit 3010 wireless point of sale terminal (POS) was tested at low, middle and high channels with the antenna oriented in one position (at the antenna side of the terminal, 0 o , where it is most likely to come in contact with the user’s hand). The maximum SAR (4.45 W/kg) was found to coincide with the peak performance RF output power of channel 2000 (low, 806 MHz), with the antenna side of the DUI facing up against the bottom of the phantom. Test data and graphs are presented in this report. Based on the test results and on how the device will be used, with the duty factor of the POS intrinsically limited to less than 3% (see Appendix G), it is certified that the product meets the requirements as set forth in the above specifications, for an uncontrolled RF exposure environment for extremities (hand). (The results presented in this report relate only to the sample tested.) Page 3 of 24Project #: LPMB-Nurit 3010 DataTAC-3516U 51 Spectrum WayTel.

The relevant portions of the FCC’s e-mail follow with our responses inserted in the appropriate place: Sent:Wednesday, September 20, 2000 4:46 PM To:John Carpino, [email protected] Lipman USA, inc. From:Joe Dichoso, [email protected] FCC Application Processing Branch Re:FCC ID O2SNURIT3010A Applicant:LIPMAN USA, INC. Correspondence Reference Number:16217 731 Confirmation Number:EA98745 Date of Original E-Mail:09/20/2000 1. It is indicated in the SAR report that the device may be carried in a case that hooks onto a belt. Please confirm if the device may transmit in body-worn configurations and if so, verify that the 3.2 cm separation needed separation determined for 1-g SAR compliance can be provided by this belt-worn configuration. The plastic of the holster actually prevents a credit card from being swiped and therefore the terminal cannot transmit when in the holster. 2. Duty factor info indicates regular transaction time is 6 seconds and it takes another 10 seconds before the next transaction can occur. This would result in a typical transmission duty factor of 6/16 = 37.5%. Note: For RF exposure purposes, maximum duty factor is need. Depending on the transmission protocol and network implementation, byte counts may not always be applicable for determining RF exposure duty factor; especially when RF carrier stays on when no bytes are sent at certain intervals. Please clarify and provide additional info that is applicable for determining the worst case source-based time-averaging duty factor (see 2.1093). * 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] The POS does not in fact transmit for the whole 6 seconds. It only transmits a maximum of 500 bytes of data, which would take about 200 milliseconds of the 6 seconds at 19200bps. The fastest possible transaction duration is 3 seconds which includes: swiping the credit card/debit card, keying in the transaction amount, keying transmit, transmitting, printing out and tearing off the transaction slip. The absolute maximum duty factor in this case would be 6.94% for a 500 byte transaction. 3. The SAR report has indicated that the manufacturer of this POS device will implement additional software to limit the maximum duty factor to 2.1% but t…
