WARNING
Improper use can cause injury. Use the DDU-120 AED only as instructed in the 
User Manual. The DDU-120 AED delivers electrical energy that can potentially 
cause death or injury if it is used or discharged improperly. Do not discharge with 
defibrillation pads touching or gel surface exposed.
WARNING
Disconnect all non-defibrillator proof equipment from the patient before 
defibrillation to prevent electrical shock hazard and potential damage to that 
equipment.
CAUTION
Avoid contact between parts of the patient’s body and conductive fluids such 
as water, gel, blood or saline, and metal objects, which may provide unwanted 
pathways for defibrillating current.
