If your Arc's chime is very quiet, makes a "thunk" or dull sound at the beginning of the chime sequence, or does not sound at all, follow the steps below.

Step 1: Confirm the device is receiving power

Unstable power can cause chime issues. Try the following:

• Plug into a different wall outlet (some outlets are controlled by a wall switch — try one you know is always on)
• Try a different USB-C power adapter if you have one available

If Arc isn't receiving wall power, a power-loss icon will flash on the display about every 10 seconds and stop once power is restored.

Step 2: Check your firmware

Outdated firmware can cause chime issues. Check whether you're on the latest version and update if needed here.

Step 3: Calibrate your chime

Enter chime calibration mode and check the current chime setting - Chime calibration controls both the volume and the distance of the chime striker. You can find instructions on how to calibrate your chime here.

Still not working?

If you've tried both steps and the Arc still isn't responding, please contact our support team. When you reach out, it helps to let us know:

• What you're seeing (or not seeing) on the display
• Whether the power-loss icon was flashing before the issue started
• What you've already tried

We'll take it from there.
