The Depict Frame has two power saving modes: sleep mode and powered off.
To place the Depict frame in sleep mode, simply press the power button on the side of your frame for 1 second. The frame should say "Going to sleep..." When you're ready to reuse the frame, tap the power button again, and the frame will quickly turn on and display the most recent image from the Depict Collection you displayed.
To turn the frame completely power off, hold down the power button on the side of the frame. You will want to hold the power button down for around 10-15 seconds. You will notice a countdown message appear on the screen while you are holding down the power button. Keep holding down the power button, until the countdown message has cleared and the screen has turned black. If you release the power button too early, the frame will be triggered to restart.
If you would like to turn the frame on after completely powering it off, press the power button again. The frame will go through a full boot, and when it's ready, it will display the most recent image from the Depict Collection you displayed.
