・ The unit is waterproof up to 55M. Do not bring the unit deeper than 55M.※
The deepest possible point for recreational diving is 40M.
・Surfactant as detergent makes water enter inside the unit easier. Do not put untifog
liquid on the unit. If it is attached, wash it away with pure water or sea water at once.
・Soaking the unit into chemical substance deteriorates the unit condition. If hairdressing,
detergent or sunscreen is attached, wash it away with pure water at once.
・Do not drop the unit to the ground. You can enter the sea as usual with the unit.

settingposition
IMPORTANT!
Set the unit at right side of mask strap by clip.
To avoid dropping the unit, set a strap at the strap holder
and put it into the mask.
After purchasing, charge the power of the unit first. For details, please refer to the [10 How to charge]
■Set a bone conduction microphone as touching the bone in front ofantilobium (base of jaw).
(Please refer to the drawing above). The sound transmitted by bone conduction has extremely
little vibration. Touching the microphone to the above section correctly and attaching close to
your face is most important to transmit the sound to other divers. Adjust microphone setting
positions to hear the transmitted voice in the best condition. Setting position of speaker does
not make much difference on its performance.
■Using Logosease with a store-bought hood together is not recommended. Make sure to wear
the hood specialized for Logosease (sold separately) when you use a hood.
■In setting the unit with a store-bought hood, setting a microphone outside on the hood causes difficulty in
collecting bone conduction sounds, and the sound becomes smaller. Although you can set the unit under
the hood in use, you should be careful not to drop the unit to the bottom of water since you can not set a
clip at the mask strap.
■Hood shields ultrasound. When setting the unit under the store-bought hood, please make sure not to
cover the antenna by hood. You may feel pain on your face where the unit touches under the hood
by tightening the hood.
■An antenna is set toward the front, and designed as the strongest level of ultrasonic sound can
reachat the line of sight. Anything including barriers and bubbles attached to the antenna degrades
transmitting/receiving quality. Make sure nothing is attached to the antenna.

SpeechTrainingSheet

IMPORTANT: Before actually start speaking underwater,,,
please practice speaking with a regulator in your mouth at the beginning.
Power will be ON automatically by putting the unit in the water. Then LED will be ON to indicate
battery status for 2 seconds. LED blinking in red indicates battery is not charged. In this case,
please charge the battery. Green LED indicates battery is fully charged. Blue LED indicates
battery is enough for one shot diving. If battery is not charged at all, the power will be OFF. Please
charge the battery then. 1 second after showing battery status,the unit will move to receiving mode.
When starting transmitting, tap the side of the unit one time lightly. You will hear pi, bo, from
your own speaker to make the mode transmitting.
No sound for 3 seconds or tapping one time makes the transmitting mode finish. You will hear
pi, bo, bo, bo from your own speaker, and the mode will change to receiving mode.
*Acceleration sensor detects tapping. The sensor may cause glitch to make the mode transmitting accidentally. In this case,
tap the unit again to make the mode back to the receiving mode.
* Applicable transmitting distance is within visual range. If distance is too close or in the location where sounds echoes
easily such as in a pool, acoustic feedback may happen between 2 units.
Power will be OFF automatically in 1 minute after bringing the unit out of water. The sound of
pi, pi, pi, pi, peep, peep, peep, peep will be released to notify the power is being OFF.
Power will be ON/OFF by detecting water.
To get accustomed the conversation underwater smoothly,
please use the attachedSpeech Training Sheet in
practice. You will learn how to pronounce underwater
and get the knack of smooth conversation.

One full-color LED is built-in. In receiving mode, LED blinks in yellow in 1 second period. In
transmitting mode, LED is ON in pink. You know if it is transmitting mode or receiving mode by
seeing LED of the unit.

Wash the unit with pure water to wash sea water and dirt away, then dry it with dried cloth before
storing. Do not wash with detergent. Especially, if USB terminal is dirty, it may cause a malfunction.
Clean it with brush when it is dirty. When soaking the units in water to get the salt out, make
the units' mode receiving. Both transmitting and receiving modes exist, acoustic feedback
may occur.
9.Maintenanceafterdiving
Power is ON -> checks battery status for 2 seconds ->then in 1 second, the unit becomes receiving
mode automatically. In this mode, no sound is heard until voice is transmitted. When transmitting
by other diver, the voice will come out from the speaker. In receiving mode, LED blinks in yellow
in 1 second period.
