Industry Canada Statements RSS-GEN 7.1.2 – Transmitter Antenna / Antenne de L'émetteur Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication. Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante. This radio transmitter 7955A-SRF305 has been approved by Industry Canada to operate with the antenna types listed below with the maximum permissible gain and required antenna impedance for each antenna type indicated.

Small Receiver Transmitter (SmaRT) LOBSRF305 RT Module Radio Transceiver SAR Testing 2013 December 11 V0.0  2013 Cervis Inc. All rights reserved. 170 Thorn Hill Road • Warrendale, PA 15086 Phone 724.741.9000 • Fax 724.741.9001 www.cervisinc.com 2 Table of Contents Introduction Operational and SAR testing of LOBSRF305 3 Overview Introduction This document describes in detail SAR testing of the LOBSRF305 RF transceiver (RT) module for use in host applications. An HH-2H06 is provided to control the RT module in a typical way. It is assumed that the reader has some hardware and software background related to microprocessor based embedded systems and RF transmitting and receiving devices. Equipment provided Several exhibits are provided to facilitate the emissions testing of the LOBSRF305 RT module: 1: LOBSRF305 attached to HH-2H06 host application, U.FL antenna fitting LOBSRF305 has an attached fixed internal dipole antenna with a U.FL connector 2: External 9 dBi omni antenna, RP-TNC 3: RG-316 adapter cable, U.FL<->RP-TNC 4: Spare AAA alkaline batteries Typical operational firmware is provided in the HH-2H06 device controlling Exhibit 1. Setup - General Set up a demonstration by attaching an antenna to the LOBSRF305 and installing the batteries in the HH-2H06 device to be tested. If the HH-2H06 doesn’t turn on immediately then briefly press any button 1-5 to turn on power. It is OK to operate an HH-2H06 without an antenna. No damage will occur, but RF performance will be limited to leakage signals. Exhibit 1 is mechanically fragile. Handle with care and do not bend the wires too much. Operational and SAR testing of LOBSRF305 Exhibits 1, 2, and 3 are provided to demonstrate and test normal operation of a host application that uses an LOBSRF305 RT module. All devices have typical application firmware installed. Setup for internal fixed antenna Chapter 1 4 The LOBSRF305 internal antenna may be connected to the U.FL connector on the PCB by carefully snapping the U.FL plug into the U.FL socket. Setup for external replaceable antenna Setup of the LOBSRF305, exhibit 1, requires installation of the batteries. If the unit does not immediately start operation briefly press any button 1-5. Press and hold button 6 for several seconds to turn the unit off. Normal operation is indicated by the green TX LED blinking every 100 ms. Pressing any button 1-5 will cause the TX LED to become brighter. The LOBSRF305 external antenna, exhibit 2, may be connected to the U.FL connector on the PCB by carefully snapping the U.FL plug of exhibit 3 into the U.FL socket. Connect the external antenna, exhibit 2, to the RP-TNC connector of exhibit 3. The RP-TNC connector should be finger tight. Normal Operation The equipment provided for these test has typical production firmware installed, as would be used in a typical host application. The TX RF duty cycle of the HH-2H06 is approximately 1% and the conducted RF power is approximately +19.94 dBm. Every 100 mS, indicated by the green TX LED blinking, the HH-2H06 will transmit a message. Whenever a button on the HH-2H06 is pressed, the TX LED will blink longer and appear brighter. Press any button 1-5 to turn the HH-2H06 on. The TX LED will start blinking. Press and hold button 6 to turn the HH-2H06 off. The unit will be off when the LEDs are off. SAR Testing SAR testing may be performed on the LOBSRF305 RT module portion of exhibit 1.
