  2. Connect the AC power adapter (if included, or use a standard USB power adapter if the clock has a USB power input) to the DC IN port on the back of the clock and then plug it into a standard wall outlet. The display will light up.

5.2 Setting the Time

  1. Press and hold the TIME button until the hour digits begin to flash.
  2. Press the HOUR button repeatedly to adjust the hour. Pay attention to the PM indicator if setting a 12-hour format.
