• After turning the Blue Ocean Megaphone on, push the talk trigger
to activate the Blue Ocean Megaphone for speaking. For maximum
battery life, push the talk trigger only when speaking.
• Hold your mouth close to and in line with the foam microphone
screen. Use a normal to slightly increased speaking volume to
maximize clarity.
• Adjust the volume to a level where there is no feedback (howling,
squeaking or squealing sounds). This level will differ depending
upon the openness of the area of operation and the volume of your
speaking voice.
• To maximize volume and clarity, point the megaphone directly toward your listeners from a safe distance.
• To reduce feedback, do not aim the Blue Ocean Megaphone
directly at solid surfaces or the water.
