Is it possible to activate or deactivate the controller accidentally?
The controller is activated/deactivated by a simple press of a button. The controller itself is housed in a seperate zippered pocket on the bottom of the bag. A bright red LED blinks when the controller is activated and can be seen through a clear window on the controller pocket. If you are still concerned about mistaken activation, you can easily remove the controller from the integrated pocket and pack the controller seperately. A male and female (lockable) wiring harness to connects the internal wiring with the controller. You could also keep the controller in the pocket but simply disconnect the male female wiring harness when you pack it up, and then reconnect the wiring harness when you want to to activate the bag at camp.
