Channel read-out
In some use cases the display is not directly visible to the user (e.g. if the
radio is used in a belt or pocket). Consequently, when changing to a new
channel (using the Up and Down buttons) the user cannot positively
know which channel is now the current one.
The channel read-out feature, however, enables users to get audible
feedback on channel name in a connected headset (or speaker-mike)
