INTRODUCTION
Thankyouforselecting theECG3.TheECG3 isanautomaticsingle -leaddynamic
electrocardiogram(ECG)recorder,whichcan recordand store 72hourECGdataatmost.
ECG3 cantransmit currentECGdatatoaniOS device withBluetooth on whichusercan
watch thecurrentECGwaveform and heartrate.The ECGdatastored inECG3can be
uploadedon aniOSdevice with adatacable,which willbeautomaticallyanalyzedand
displayed.The heartrate iscalculatedbycounting the heartbeatsineach 30sandthe
maximumand minimumheartrateiscalculated ineveryhour.

OPERATIONINSTRUCTIONS
a. RemovethereleasepaperatAsideoftheelectrode,
andpastetheelectrodeatthepositionofchest
shown in the figure onthe rightside (Note:Clean skin
beforepastingtheelectrodeif possible,whichis
conducivetotheaccuracy ofmeasurement).Then
removethereleasepaperatBsideoftheelectrode.
The electrodeisdisposableand donottrytouse itagain.
b. Fasten ECG3withthebase on the electrodeand ensure thatthe ECG3hasagood
contactwiththeelectrode.Press the UserkeyonECG3forabout2s,the ECG3
