Simplified Operating Instruction, 340M OB Telemetry, 608-614MHzGE Medical Systems Information Technologies 4/9/01Page 1 of 8340M OB Telemetry Simplified Operating InstructionsOverview:The 340M OB Telemetry system is comprised of a transmitter and receiver to provide an RF link betweenpatient worn transducers and fetal monitor, allowing patient to freely move about while staff monitor fetalheart rate and uterine contractions remotely.The 341 Receiver is line powered from 120 VAC, and the 342 Transmitter is powered from (4) AA sizeprimary 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 forSAR testing and the radiation hardened will be used for other testing.Other accessories are provided for their use in testing, if necessary.Descriptions: (refer also to 340 Service manual, pages 3-2,3,4)341 Receiver:Front Panel:AC power switch far rightToco/Iup mode change switch leftIndicator lamps center rightSignal strength indicator, green topBattery status, red centerAC mains, green bottomRear Panel:Power Entry Module far left topMark interconnect cable Jack far left bottomSystem Interconnect cable jack left bottomUltrasound interconnect cable jack bottom centerECG interconnect cable jack bottom rightUA interconnect cable jack bottom far rightEquipotential ground jack top center

Turn ‘OFF’ when notneeded to conserve battery.UA Ref pushbutton:Forces UA simulated signal to a baseline level for physiologic signal drift testing. Notused for RF testing.Adjustment Potentiometer:Allows UA simulated signal to be offset from baseline level by adjustable amount. Notused for RF testing.
