Your Blue Ocean® Megaphone is completely waterproof and will not
be harmed by use in the rain. However, if the wind screen foam in-
side of the microphone port becomes saturated with water, the water
will inhibit sound from reaching the microphone and result in poor, or
even no, sound transmission. Accordingly, we recommend that you
avoid allowing rain to fall directly into the microphone port. If the port
does become saturated with water, you can clear it by holding the
megaphone battery side down and shaking it, or by blowing once or
twice directly into the microphone port until your voice is clear again.
It is not necessary for the wind screen to be completely dry. Do not
attempt to poke or squeeze the wind screen dry as this may
damage the waterproof membrane at the base of the micro-
phone port, destroying the waterproof seal of your unit.
