Performing monthly checks is a quick and easy process. Simply view your AED to ensure that the Readiness Indicator is positive, check your pads and battery to ensure they are within date, take a quick look to make sure your AED shows no signs of damage or tampering, and your monthly check is complete!Your AED also performs daily, weekly, and monthly automated checks internally, and indicates the results of these tests via the Readiness Indicator. In addition, we track the expiration dates of your supplies within the program and automatically alert you when new supplies are needed.
