BASIC USER GUIDE
Audio Signal Tones
High pitched tone
Low pitched tone
High pitched tones generally are positive
indicators used for example to inform you of
incoming calls, starting a feature and good status
(e.g. radio power up OK).
Low pitched tones generally are negative
indicators used for example to inform you of time
restrictions, stopping a feature and bad status (e.g.
error conditions).
Audio Indicators for Programmable Buttons
Some programmable buttons function as toggles,
alternating between two different choices. These
buttons use audio tones to indicate the change.
