Audible tones
The radio uses audible tones to alert you to its status:
■ Radio controls and keypress tones—the tones
and beeps you hear when you press your radio’s
keys or use the controls.
■ Incoming call tone—when the radio is receiving
a call.
■ Warning tones—when there is an error.
Warning If quiet or silent mode is turned on, you will
not hear any alert tones.
Some of the more common audible tones are
described below:
