Installing Batteries in the wECG Module
ThewECGmodulecanacceptuptotwobatteries.Dependinguponthenumberofbatteries
installed,thewECGmoduleprovidedifferentoperationalfeatures:
•Ifonebatteryisinstalled,thenthewECGmodulewillturnonandfunctionnormally—but
beforeitschargeisexhausted,asecondbatterymustbeinstalledinorder
tocontinuethe
ECGstudy.
•Iftwobatteriesareinstalled,thenseamlessoperationispossible—onebatterywillprovide
poweruntilitschargeisexhausted,atwhichtimethewECGmodulewillautomatically
switchtotheremainingbatteryforcontinuedoperation. Aslongassufficientpoweris
providedbythesecondbattery,
continuedoperationispossible.And,anexhausted
batterycanbereplacedatanytimewithoutinterruptiontotheECGstudy,providedthat
sufficientchargeispresentontheremainingbattery.
