What Do All the AED Sounds & Lights Mean?
AEDs are designed for ease of use by anyone, even without first aid training. They come equipped with a variety of user-friendly sounds and lights to guide users through the rescue process easily.
In this article, you will learn about AED sounds and lights, as well as what they mean.
***This article will outline the indicators of Philips HeartStart models.
Understanding AED Sounds
AEDs emit several types of sounds, each with a specific purpose. Let’s break down the sounds you might encounter on Philips HeartStart AEDs.
Voice Instructions & Coaching
During use, AEDs provide voice instructions to guide the user through each step. These instructions are clear and concise to ensure that even someone with minimal training can follow along.
When the i-button is pressed during a patient care pause, it provides verbal CPR Coaching.
Chirps
Both the Philips HeartStart FRx and OnSite defibrillators run regular tests on themselves and use “chirps” in the process. Chirps can indicate a range of issues including:
- Expired AED pads
- Expired AED battery
- Mechanical error
- AED pads not plugged in
- AED pad cartridge error
- AED not kept in operating temperatures
If you hear a single chirp on your AED, press the flashing blue i-button for information about the device’s status or troubleshooting guidance. You may also consult the troubleshooting guide in the device’s operating manual. If you hear a triple chirp alert, there may be a serious problem which could prevent the AED from functioning in an emergency and you should contact us immediately.
Regular maintenance is key to keeping your AED operational. Learn more in our Monthly AED Maintenance Guide.
Understanding AED Lights
AEDs also use lights to communicate their status and guide users through the rescue process.
Ready Light
On Philips HeartStart FRx and OnSite defibrillators, the ready light is green. When this light blinks, it means the AED is in standby mode and ready for use. A solid green light indicates the device is actively being used.
Caution Light
The caution light flashes when the AED is analyzing the heart rhythm. On Philips HeartStart models, this light becomes solid when the device advises a shock, reminding you not to touch the patient during this critical moment.
Shock Button
The shock button on Philips AEDs is orange and flashes when the device is charged and ready to deliver a shock. The defibrillator will instruct you to press this button to deliver the shock to the patient.
Information Button (i-button)
The blue i-button flashes to indicate that there is information or troubleshooting guidance available. Pressing this button provides important details about the device’s status, usage, or any issues that need addressing.

In a high-stress situation, Philips HeartStart AED sounds and lights offer straightforward guidance to keep you calm and focused. By familiarizing yourself with these signals, you can act swiftly and confidently during an emergency.
Getting formally trained can significantly enhance your ability to respond effectively. At First Edition, our CPR and AED training course includes hands-on practice with devices where you’ll get familiarized with specific sounds and lights to prepare you for real-life scenarios.
