To put your RemoteLync camera in sleep mode hold down the button for approximately 20 seconds with no USB connected.  During this time the indicator light will flash amber and red.  When the indicator is solid red release the button and you will get audio confirmation from the RemoteLync camera that it is in sleep mode.  To wake the RemoteLync camera up from sleep mode simply connect the device to USB power.

Note: the buttons will not respond if the camera is armed. First disarm the camera using your smartphone app.
