The VHF 725 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 725 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 current unit operating mode.
Screen Messages
“LOW BATT” - This display appears when the battery capacity 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
