Audible Tones
The radio uses audible tones to alert the user to its status:
• Radio controls and keypress tones—the tones and beeps that are audible when the radio’s keys are pressed or
the controls are used.
• Incoming call tone—when the radio is receiving a call.
• Warning tones—when there is an error, or the battery is low, for example.
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:
