RF Exposure (OET Bulletin 65) To comply with FCC’s RF exposure limits for general population / uncontrolled exposure, the antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. Industry Canada Statement per Section 4.0 of RSP-100 The term "IC:" before the certification / registration number only signifies that the Industry Canada technical specifications were met. Section 7.1.5 of RSS-GEN Operation is subject to the following two 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. Page 3 of 3 OEM Responsibility to the FCC Rules and Regulations The Apex LT Module has been certified per FCC Part 15 rules for integration into products without further testing or certification. To fulfill the FCC certification requirements the OEM of the Apex LT Module must ensure that the information provided on the Apex LT Label is placed on the outside of the final product. The Apex LT Module is labeled with its own FCC ID Number. If the FCC ID is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following: “Contains Transmitter Module FCC ID: TFB-APEXLT” or “Contains FCC ID: TFB-APEXLT” The OEM of the Apex LT Module must only use the approved antenna, which has been certified with this module. The OEM of the Apex LT Module must test their final product configuration to comply with Unintentional Radiator Limits before declaring FCC compliance per Part 15 of the FCC rules

May 10, 2007 Re: Modular Transmitter Approval FCC ID: TFB-APEXLT Gentlemen, The following information is being provided per the requirements of DA00-1407 regarding modular approval of Part 15 devices. This transceiver is a complete RF module with an integral reference oscillator. External connections are provided for power and data communication. The following numbered items correspond to similarly numbered paragraphs in DA00-1407. Each item is a response to the requirements of that document. 1) The module has integral RF shielding to isolate it from surrounding equipment and the larger environment in general. 2) All inputs are processed as data by the on-board microcontroller. The outside user has no direct control of transmit modulation. 3) There is a 1.8V voltage regulator on board that powers the radio and the power amplifier. 4) Either an integral PCB – trace antenna or a Nearson S131CL-5-RMM-2405S antenna with an MMCX connector is used with this module. This is in accordance with Part 15.203. 5) The module was tested in a stand-alone configuration and found to be compliant with Part 15 regulations. 6) An FCC ID label is affixed to each unit at the time of manufacture. Information is also clearly presented in the user guide about labeling requirements for the final assembly. 7) This unit is compliant with Part 15.247. Installation and other requirements are presented in the user guide to allow the unit to be correctly installed. 8) The unit is compliant with the RF exposure requirements of Parts 15.247, 15.1091, and 15.1093.

MPE CALCULATIONS The following MPE calculations are based on the Nearson Whip antenna. Although the highest actual measured power was 18.56 dBm on the low channel, 2405 MHz, a nominal conducted RF power of +20.0 dBm was used in the calculation for worst case. The stated gain of the antenna, is published at 2.0 dBi, and is reduced by the cable loss depending on cable length. For this calculation, the cable loss has been left at zero, although measurements of the samples provided, were with a 5 inch cable length. A comparison of measured EIRP and calculated EIRP shows favorable correlation. Prediction of MPE limit at a given distance Equation from page 18 of OET Bulletin 65, Edition 97-01 where:S = power density P = power input to the antenna G = power gain of the antenna in the direction of interest relative to an isotropic radiato r R = distance to the center of radiation of the antenna Maximum peak output power at antenna input terminal:20.00 (dBm) Maximum peak output power at antenna input terminal:100.000(mW) Antenna gain(typical):2(dBi) Maximum antenna gain:1.585(numeric) Prediction distance:20(cm) Prediction frequency:2405(MHz) MPE limit for uncontrolled exposure at prediction frequency:1(mW/cm^2) Power density at prediction frequency:0.031530(mW/cm^2) Maximum allowable antenna gain:17.0(dBi) 20cm =15.0 dB Margin of Compliance at 2 4R PG S π =
