How to Calibrate Clock HandsUpdated 5 months ago

The analog clock hands are factory-calibrated and synced with the digital display. If the clock hands are not showing the same time as the digital display, the device allows for manual recalibration.

1. Enter Calibration Mode

Press and hold the Clock Time Knob for 10 seconds. The clock hands will move to 11:59 PM.

2. Align Clock Hands to Midnight

Turn the front Alarm Knob clockwise slowly until the minute hand reaches midnight (12:00 AM). 

IMPORTANT: If you pass midnight during calibration, short-press the front Alarm Knob to restart. To exit without recalibrating, press any button to cancel and exit.

3. Save and Exit

Press and hold the front Alarm Knob for 10 seconds until a checkmark appears.

4. Set your current time

Arc will now reset to midnight. When you see the deactivate alarm bell icon, short press Clock Time Knob to reset your current time.
