This is especially useful if the radio isdropped overboard or during extreme foul weatherconditions. In these conditions, water can become trapped inthe speaker grill and muffle the audio. To Activate Burp:1. Press and release the 16/9 and SCAN keys at the same time. 2. The Burp tone(s) at maximum level will sound from the internal speaker for eight seconds. 3. During this time, the matrix will display BURP.4. Hold the radio with the speaker grill down to help the water drain out.5.
