Note
There may be moisture inside the main unit (water tank) left from the distilled water used for product testing.

Charging

• Please wipe off any water droplets from the socket or socket cover.

1. Open the socket cover, and insert the USB plug (Type-C) of the USB cable into the socket on the main unit.

If the socket cover comes off

1. While holding the main unit with your hand, press and hold the socket cover with your thumb so that the soft rubber joint (mushroom-shaped) of the socket cover is aligned with the fixing hole.
2. As shown in the figure, push the soft rubber joint (mushroom-shaped) into the fixing hole with a SIM ejector pin. (Do not use a sharp-pointed tool as this may cause damage to the soft rubber joint or a hand injury.)
3. Make sure that the soft rubber joint (mushroom-shaped) is fully pushed into the fixing hole.

2. Insert the USB plug (Type-A) of the USB cable into the USB port (Type-A) of the USB power adaptor.
   • Check the direction of the USB plug (Type-A) terminals, hold the USB plug (Type-A), and insert or pull it out straight. (Deflection or insertion in a wrong direction may cause deformation or malfunction.)
3. Insert the USB power adaptor into the household outlet.
   
4. Charging is completed after approx. 1 hour. For safety, disconnect the USB power adaptor from the household outlet after charging is completed. (The charging time may vary with the remaining battery capacity.)
   • Remove the USB plug (Type-C) from the socket, and close the socket cover.
   • Charging the battery for more than 1 hour will not affect battery performance.
   • This appliance uses a Lithium-ion battery. Therefore, the service life of the battery will not be affected even if it is charged after each use.

Operating time after a full charge
Approx. 10 minutes*
(When the water pressure level is set to 5)
* It varies with the ambient temperature and usage conditions.

About the charging reminder function

• If the battery is running low, the charge status indicator will start flashing (once a second) during use and light off in 5 seconds after turning off the power switch.

Display condition of the charge status indicator
Charging in progress	Lights on
Charging complete	Lights off
Charging abnormal	Flashing (Flashing in red twice a second)

How to check if charging is completed

• After charging is completed, if you disconnect and then connect the power supply, the charge status indicator will light on and then light off in about 5 seconds.

Notes

• The charging time may differ when the appliance is used for the first time, or if it has not been used for more than 6 months. In addition, the charge status indicator may not light on in the first several minutes of charging, but it will light on as the charging proceeds.
• The recommended ambient temperature for charging is 10°C - 35°C. It may take longer to charge, or the charge status indicator will flash rapidly and the battery may fail to charge properly in extremely high or low temperatures.
• The battery will deteriorate if not used for over 6 months, so make sure to perform a full charge at least once every 6 months.

How to use

1. Fill the water tank with water.
   
   1. Open the water tank cap.
   2. Add water while keeping the main unit level.
      • Do not fill beyond the full-water position.
   3. Close the water tank cap securely. (When the full-water position is reached, or when the water tank cap is closed after the full-water position is reached, a small amount of water may flow out of the air vent.)

If the water tank cap comes off
You can attach the water tank cap by following the procedure below when it comes off.

2. Install the nozzle.
   • Choose a nozzle for your purpose. (See "Points of care")
   • Press in firmly until a "click" is heard.
     
3. Press the level switch, and select the water pressure level.
   • Each time you press the level switch, the water pressure level is switched as follows: 1 (weak) → 2 → 3 → 4 → 5 (strong) → 1...

About the water pressure level memory function
The last selected water pressure level will be remembered, from which the appliance will start next time.

• When the appliance has not been used for a long time or when the battery is used up, the water pressure level will return to 1

4. Place the nozzle in your mouth, close your mouth gently, and then turn on the power switch to rinse your teeth.
   • You can switch the water pressure level by pressing the level switch, even while using the appliance.
   • If the main unit is tilted too much, the water does not come out from the nozzle.
   • During use, be careful not to cover the air vent with your hand. Otherwise, the water does not come out from the nozzle.

Operation time with full water
approx. 60 seconds.
(When the water pressure level is set to 5)

5. To prevent the water from splashing about, turn off the power switch while keeping the nozzle in your mouth.
   • Please clean the appliance after each use. (See "Cleaning")

Notes

• The appliance does not work during charging.
• Always use new tap water or lukewarm water. (Do not put salt, mouthwash or other chemicals into the water tank.)
• If you feel the water is cold, use lukewarm water with a temperature of 40°C or less.
• For the first use, turn on the power switch to jet water so that you can check the water pressure level. (Please start using the appliance from water pressure level 1.)
• The appliance may not operate in an ambient temperature approximately 5°C or lower.
• Do not push the tip of the nozzle too hard against the teeth or gums. (Except the orthodontic nozzle)
• When you feel that the irritation is strong, turn off the power switch and use the appliance from water pressure level 1.
• Do not turn on the power switch when the water tank is empty unless you are drying the moisture inside the main unit. (Doing so may cause malfunction.)

Points of care

• Adjust the angle and movement of the nozzle according to the purpose and the area you want to clean.
• For areas where the gums are sensitive, please set the water pressure level to 1.

Important information

• Please use the appliance together with toothbrush. It is hard to remove tartar or dental calculus attached to the tooth surface just by a water jet, so a toothbrush is required to brush the teeth. We recommend rinsing the inside of your mouth with the water jet after brushing your teeth.
• When you first begin using the oral irrigator, you may experience slight bleeding of the gums even though your gums may be healthy. This is because your gums are receiving stimulation by the oral irrigator for the first time. The bleeding should stop after one or two weeks of use. Bleeding that persists for more than two weeks may be indication of an abnormal condition of your gums, such as periodontal disease. In this case, stop using the oral irrigator and consult your dentist.
• The USB cable provides the overheat protection function. If charging is abnormal or the USB plug (Type-C) heats up, disconnect the power supply, check the socket, and remove any water or foreign objects from the socket.
