• Plug an NK Blue Ocean Microphone into the microphone connector
to enable hands-free operation.
• The Blue Ocean Megaphone amplifier is always “on” when the mi-
crophone is plugged in. It is not necessary to push the talk trigger.
• Depending on conditions, you may be able to use a higher volume
setting when using the external microphone without experiencing
feedback. Use of the external microphone is recommended when
maximum volume and range is desired.
AVOID EXCESS BENDING OF THE MICROPHONE
CABLE AND CONNECTOR WHEN PLUGGED IN.
Your Blue Ocean Megaphone is equipped with a directional noise-
canceling microphone element. Because of the extreme volume and
proximity of the Blue Ocean Megaphone speaker unit, this micro-
phone is designed to isolate your voice and prevent feedback. For
the best sound quality, position your mouth close to the microphone
port when using the internal microphone. To reduce fatigue and the
need to position your mouth when speaking, consider plugging in an
NK Microphone for hands free operation.
