As soon as your PowerRay is connected and activated, put it gently into the water.
If you try to operate the drone with a mobile device or Controller, the motor will not move.
To start diving, you need to unblock the device.
Remember, that it is possible only when the PowerRay is in water.
If you are using the Remote Controller, turn the left round scroll to the right.
Then press the FishFinder button.
Keep it for few seconds till you feel vibrations on the Controller.
As a result, PowerRay will start moving.
You can do the same using your mobile device.
In right upper corner, you will find a small lock.
Press that and then slide to unblock.
If you decide to use your mobile device, it is better to turn off the Controller.
If the PowerRay is unblocked, have a great time!
