Simplified Operating Instruction, 340M OB Telemetry, 608-614MHz GE Medical Systems Information Technologies 4/9/01 340M OB Telemetry Simplified Operating Instructions Overview: The 340M OB Telemetry system is comprised of a transmitter and receiver to provide an RF link between patient worn transducers and fetal monitor, allowing patient to freely move about while staff monitor fetal heart rate and uterine contractions remotely. The 341 Receiver is line powered from 120 VAC, and the 342 Transmitter is powered from (4) AA size primary Alkaline cells. Expected life of the Alkaline cells in continuous use is roughly 16 Hrs. There are two simulators used for exercising the transmitter. One is a production simulator (Model 325) and the other is a radiation hardened simulator (built into a metal box). The 325 simulator will be used for SAR testing and the radiation hardened will be used for other testing. Other accessories are provided for their use in testing, if necessary.

Bottom Panel: Battery access door Radiation Hardened Simulator (for use at ITS, Boxborough): This is an aluminum die-cast box containing (2) Alkaline ‘D’ cells providing power, and active circuitry providing signal to the 5700 Ultrasound Transducers and UA Transducer plug. Top: Power switch: Must be in the ‘ON’ position to obtain simulated transducer signal. Turn ‘OFF’ when not needed to conserve battery. UA Ref pushbutton: Forces UA simulated signal to a baseline level for physiologic signal drift testing. Not used for RF testing. Adjustment Potentiometer: Allows UA simulated signal to be offset from baseline level by adjustable amount. Not used for RF testing. Page 2 of 8
