Why is the ASI blinking red on my Defibtech Medical Equipment?

If your Defibtech Medical Equipment unit's ASI blinks red, it could be due to several reasons: * ASI 9V battery low: Replace the ASI 9V battery. * Unit needs servicing: Turn the unit on and run a manually initiated Self-Test. * Battery pack non-functional: Replace the battery pack. * Electrode pads are not pre-connected to the unit: Connect the electrode pads to the unit.
