BEFORE USE: CHIME INFORMATION

Quiet Chime: If your Arc arrives cold from shipping, let it warm to room temperature (above 54°F/12°C) for 2 hours before use.

Cold temperatures thicken the chime's lubricated components, affecting sound quality. Once at room temperature, if you would like to tune your alarm louder or softer, please head here for chime calibration instructions.

About The Chime Melody: The Arc Alarm Clock's melody is thoughtfully designed to ease you into wakefulness. It flows through three distinct phases:

Phase 1 (0–14 seconds): Starts at the softest volume, to nudge you awake without startling.

Phase 2 (15–45 seconds): Gradually increases sound to medium volumes, with a mix of slightly louder tones, offering a gentle progression.

Phase 3 (46 seconds onward): Brings in the loudest volume more frequently, to ensure even deep sleepers are awakened. This phase lasts for 3 minutes before the alarm automatically snoozes if not turned off.

DISPLAY AND NIGHT LIGHT

1. Display Brightness

Press the back Brightness Knob (D), turn to adjust brightness of the Digital Display (B) and night light. Press again to set.

2. Night Light

Press the Snooze & Light Bar (E) to illuminate the clock face. It will stay lit for 10 seconds, or press the bar again to turn it off sooner.

3. Turn OFF Digital Display

For total darkness, press and hold the Snooze & Light Bar (E). When the display is off, interact with any button on Arc to turn on the digital display.

POWER

1. No Power

Arc should always be left plugged in. If Arc is unplugged or there is a power loss, the Digital Display (A) will flash a "No Power" icon every 10 seconds. Arc has a rechargeable backup battery which is able to provide 16 hours of backup power.

2. Turn off Arc Alarm Clock

Unplug Arc. When Arc is unplugged the back-up battery will be enabled. To fully turn off the device, simultaneously press and hold the Clock Time Knob (C) and Brightness Knob (D) for 10 seconds.
