• 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 to-
ward your listeners from a safe distance.
• To reduce feedback, do not aim the Blue Ocean Megaphone
directly at solid surfaces or the water.

• Plug an NK Blue Ocean Microphone into the microphone connector
to enable hands-free operation.
• The Blue Ocean Megaphone amplier 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.

• The siren and fog horn modes are
always available and do not re-

• Push the S/H button down towards “H” to activate the fog horn.
Release to turn off.
• The siren and foghorn are always at “Max” volume and the volume
is not adjustable.

again. If the error persists, try re-charging
the battery in the charging dock. If the error
light persists after these steps, remove the
battery and contact NK for support.

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.

BATTERY CHARGING & CAPACITY
• Charge your battery pack ONLY with an NK or Blue Ocean battery
charger following these instructions. You may also safely use an
NK Cox Box following the provided instructions if available.
• Plug the charger into a standard wall outlet. NOTE: The battery
charger is capable of accepting all world currents. If traveling,
you need only obtain an inexpensive adapter plug for your
destination’s outlet conguration to use your battery charger.
• NOTE the alignment guides on the battery pack – two on one end,
one on the other.
• Align the battery pack guides with the matching grooves on the
Charger and insert the battery pack. DO NOT FORCE the pack into
the charger.
• Turn the battery pack knob until it clicks. The battery will
begin charging.
• Charging Time: Charging a fully depleted battery to 100% requires
12 hours. A partially discharged battery will recharge more quickly.
• Operating Capacity & Standby Time: A fully-charged battery
will provide 8 hours of typical operation, dened as speaking 35%
of the time at volume level 6, and 30 hours of standby time. Hours
of operation will vary signicantly depending on the volume,
continuity of operation, and microphone use.
• Charge Retention: A charged battery will retain its charge for up
to two months if left in the Blue Ocean Megaphone and six months
if stored separately.

• Cycle Life: An NK Blue Ocean battery pack can be expected
to provide 80% of its rated capacity after 300 charge/discharge
cycles and 60% after 500 cycles. Storing, transporting or using
your battery pack at temperatures exceeding 115°F/45°C will
substantially reduce the cycle life of your battery pack.

• Overheating can be caused by
charging at temperatures over
115°F/45°C or in direct sunlight.
Remove the battery pack from the
charger and put it in a cool place. Try
charging again in a cool location after
the battery pack has cooled down.
• To attempt to clear a battery error,
remove the battery pack from the
charger then reinsert the battery pack
to restart charging. If the error light per-
sists, remove the battery pack from the
charger and contact NK for support.

MAINTENANCE & DISPOSAL
• Clean your Blue Ocean Megaphone with plain water or a neutral
detergent. Avoid contact with solvents and/or gasoline.
• Always keep a protective bumper installed to minimize impact
damage. Order a replacement bumper from NK if torn or damaged.
• Clean and maintain the rubber microphone plug and sockets with
the NK Maintenance Kit. Keep the sockets free of debris and cor-
rosion by cleaning with a ne drill bit (gure a) and lubricating with
electrical contact grease (gure b). Lubricate the outside of the
rubber plug with silicone grease (gures c and d).
BATTERY PRECAUTIONS
WARNING! THE NK BLUE OCEAN BATTERY
PACK CONTAINS LITHIUM-ION POLYMER
CELLS. FOLLOW THESE PRECAUTIONS!
• Do not ever subject to re or high temperatures
(> 140°F / 160°C).
• Do not charge, use, transport or store above 115°F/45°C.
• Do not charge below 32°F/0°C
• Do not puncture or open the battery pack.
• Do not use a pack that has been damaged or has be dis-
played repeated charging errors.
• Stop charging or use immediately and remove the
megaphone or battery charge if you see smoke
or smell fumes.
• If battery pack is damaged, avoid contact with batty electro-
lyte which may be irritating to skin, eyes and mucous mem-
branes.
• In case of battery re, evacuate the area to avoid inhalation
of fumes. If possible, over the battery with sand to extinguish
the re or use a dry ABC type extinguisher.
