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.
Notice If quiet or silent mode is turned on, you will not
hear any alert tones.
Some of the more common audible tones are
