Location CAUTION: (1) PLACING THE BUZZER IN THE COCKPIT IS NOT RECOMMENDED DUE TO THE POTENTIAL FOR DISTRACTION. THE BUZZER PRODUCES A LOUD, SIREN-TYPE SOUND WHEN THE ELT IS ACTIVATED. SINCE THE BUZZER OPERATES IN TANDEM WITH THE COCKPIT LED, IT WOULD ONLY SERVE AS A REDUNDANT WARNING INDICATOR IN THE COCKPIT.
