General Radio Operation
Home Button (h)
The Home button will always return you to the home (default) display. 
In most cases, this is the current mode. 
Some radio features require saving information in memory. Pressing 
the Home button while using those features will cause information to 
be saved before going to the home display.
Some features do not require you to press the Home button to go to 
the home display. This reduces the required number of button 
presses.
