If you ever need to reboot your camera, but don't want to leave your controller station, you can use your RP-150 controller to remotely power on or off your camera:

1) On your controller, press and hold the appropriate Camera Select button. Most likely, your camera is going to be Camera 1.

2) After holding the camera button for a few seconds, a message will appear on the touchscreen showing the current camera you've selected and what its current power state is. It's important that you have to continue holding the camera button, because once you release that button, this message will disappear. Press the ON or OFF button to power your camera on or off.
