I am going to explain Button based map panning.
Button based map panning is a four step process.
First step, you should be on the point you want to pan.
Second step, you have to press the button and you will hear a message.
Third step, raise your finger you will hear a low frequency beep.
Fourth step, you have to put back your finger anywhere on the screen, and you will hear
a high frequency beep and the map will be panned, and then you can start learning.
Again, you have to keep your finger, press the button, raise your finger, put back your finger.
