(2) Remove the Battery Cover. - The Battery Cover may not be removed easily when the batteries are not inserted.

Put the Battery Cover on the Battery Case, and push it in until it catches the claws and clicks. Push both ends firmly. - You may find it difficult to push in because the unit is made to prevent water dropping inside the unit.

■ When using alkaline batteries

■ When using nickel-hydrogen batteries

The unit can be used for approximately 8 days (if it is used for 30 minutes a day). When the Battery Low Indicator (orange) flashes, batteries will be worn out soon. Replace both batteries with new ones. When the Battery Low Indicator (orange) turns on, batteries are worn out. As the unit will not nebulize, immediately replace both batteries with new ones. - You may use manganese batteries. However, manganese batteries tend to have a shorter life.

The unit can be used for approximately 8 days (if it is used for 30 minutes a day with the batteries fully charged. When the Battery Low Indicator (orange) flashes, the rechargeable batteries have little residual power. As the unit does not nebulize, immediately recharge the batteries with a commercially available charger. - The optional AC Adapter does not function as a battery charger. Use a commercially available battery charger suitable for the batteries you are using.

General advice - Immediately replace the worn batteries with new ones. - If you are not going to use the unit for a long period of time (3 months or more), remove the batteries or rechargeable batteries. If you leave the unit without using while keeping the batteries or rechargeable batteries in it, the batteries may leak and cause trouble to the unit. - Do not use the batteries other than the ones specified for the unit. Do not use worn and new batteries together or different types of batteries together. - Do not insert batteries with the polarities (+ and -) in the wrong direction.

How to Inhale 1 Hold the Main Unit with your hand and start inhalation in relaxed posture. Slightly slant the Main unit (the side of Button) towards yourself.

Medication

Vibrator

- If medication or slobber collects on the Mesh, the unit stops nebulization. After removing the Mask Adapter, Inhalation Mask, or Mouthpiece, turn off the power once and absorb the medication or slobber with new gauze. (If a medication has high surface activity, it may exude from Mesh holes or the Bottle Cap, or the medication may leak from the Air Port.)

Do not poke the Mesh or the Vibrator with a cotton swab or a pin. • The Mesh will be damaged and cannot be used.

Absorb the medication or slobber.

- If the medication has high surface activity or viscosity such as medication solubilizing agent or expectorant, the nebulization rate may be reduced. - If you push the Button and starts the unit while the Vibrator is not immersed in the medication, (1) The Battery life may be shortened or the Battery Low Indicator may turn on. - Slant the Main Unit and check if the Vibrator is immersed in the medication, then push the Button and start inhalation. - Use the unit by immersing the Vibrator of the Inhalation Port in the medication. - Immediately after the medication is nebulized, turn off the power. (2) A metallic sound may be generated, but it is not a trouble.

2 When you finish inhalation, push the Button to turn off the power. - When the optional AC Adapter is used, unplug the power plug from the electric outlet. (Refer to Page 10.) 13
