AED-2152K is an automated external defibrillator. Featuring an LCD display, it has a user-friendly onscreen operation guide. With just three easy steps to follow, the device can be set into one of two operation modes when in use. AED mode is for untrained individuals and gives operation guidance and CPR instructions. Semi-auto mode can be set for medical professionals who can view the ECG waveform and begin immediate analysis. The energy can be reduced for use on children. A self-test function can be utilized for the battery, pad and main unit. The condition of the pads can be indicated by the pads connector.
