Garmin VHF 720 Owner's  Manual  & Reference
The VHF 720 responds to operating conditions in two ways, LCD
Display screen messages and audio tones. These messages provide
notification of errors in operation or the status of VHF 720 features.
Audio Messages
Confirmation Tones - These tones, consisting of a single "Beep",
are audible whenever you press a key on the unit and confirm
that unit is responding to your action.
Error Tones - These tones, consisting of two beeps and in some
instances a continuous string of beeps, and indicate that you
have pressed a key that cannot perform a function under the cur-
rent unit operating mode.
Screen Messages

has dropped to 10% of its capacity. The "LOW BATT" display
flashes and an initial three beep tone will be heard. The unit will
operate under normal use for approximately 30 more minutes.
"WX ALERT" - When the Weather Alert feature is activated by a
weather alert broadcast, the weather alert tone will be heard and
the "WX ALERT" display will flash. The receiver will be tuned to
the weather channel and audio will be unmuted at the user
setting or mid range volume level, whichever is greater.
"TX" and "RX" - If these two icons flash together or the "TX"
only flashes whenever the PTT key is pressed, the unit must be
serviced. Contact the GARMIN Product Support Department at
