waiting about 3 seconds, a twice White flashing means the second setting “Mount Orientation”, and so on.   

Option Selection 

When you reach the function that you wish to operate in, short press the button to get into it. After entering in, the current 

selected option is indicated by the color of the LED. Each short press of the button advances the option to the next value. 

After you finish making your selection, just wait for 5 seconds until LED starts blink quickly which indicates that the modified 

is saved and then you will be brought back to the Setup Menu level automatically. If you don’t want to change anything, just 

wait for timeout without any operation. 

Quit Menu 

To get out of the current menu just keep the button pressed (2 seconds) again until LED starts flashing White quickly.
