Audio Messages
The GNS 480 provides audio messages, as well as text. A tone accompanies every new text message. The tone
is a short “ding” that lasts less than one second. Message tones will not be generated for messages already in
the message list. If message tones are turned on, they will be played even if audio is inhibited. If a second text
message is generated while the tone is being played, a second tone will not be generated.
