Frequently Asked Questions - EW-DL84 PANASONIC

How often should I replace the brush head?

It is recommended to replace the brush head every 3 months or sooner if bristles become frayed. Use only genuine Panasonic WEW-0972 replacement heads.

How do I charge the toothbrush?

Place the toothbrush on the charging stand and plug the adapter into an electrical outlet. The indicator light will flash during charging and remain solid when fully charged. Full charge takes 12 hours.

Is the toothbrush waterproof?

Yes, it has an IPX7 rating, meaning it can be submerged in water up to 1 meter for 30 minutes. You can safely use it in the shower and rinse it under running water.

How do I clean the toothbrush?

Rinse the brush head and handle under running water after each use. Wipe the handle with a damp cloth. Do not use abrasive cleaners or immerse the handle in water.

Why does the toothbrush stop vibrating during brushing?

The toothbrush has a 2-minute timer and a 30-second interval pacer. It will pause briefly every 30 seconds to encourage you to move to another quadrant of your mouth.

How do I change the brushing mode?

Press the power button once to start. Press and hold the power button for 2 seconds to switch between Normal and Soft modes. The indicator light will change color accordingly.

What does the pressure sensor do?

If you press too hard while brushing, the toothbrush will automatically reduce vibrations and a warning light will flash. This helps prevent gum damage and enamel wear.

Can I travel with the toothbrush?

Yes, it is compact and comes with a travel case (sold separately). Ensure the battery is charged before traveling. The toothbrush is airline-friendly with its lithium-ion battery.

What if the toothbrush does not charge?

Check that the charging stand is properly connected to the adapter and the outlet. Ensure the metal contacts on the toothbrush and stand are clean and dry. If the issue persists, contact Panasonic support.

Where can I purchase replacement brush heads?

Characteristics of brush bristles (⑧)

The bristles in the center (high-density bristles) are arranged in a diamond shape, which is designed for stain care.

Storing and charging the toothbrush

• If the toothbrush stops operating when first using it (immediately after purchasing it, or after not using it for 3 months or more) or during use, charge the main unit.
• Adequate ambient temperature for charging is 5^ - 35^ .

The battery may not charge properly or not at all under extreme low or high temperatures.

• You can keep the main unit attached on the charger when not in use to maintain the full battery capacity. It will not overcharge the main unit.
• The main unit may become warm during use and charging. However, this is normal.

1 Place the charger on a horizontal and stable place such as sink or shelf.
2 Align the main unit so it is facing forward, and set it straight into the charging section.
3 Insert the power plug into the household outlet.

• The charge status lamp glows and the charging will start.
• Charging cannot start when the main unit is tilted or the bottom of the main unit is not in contact with the charging section.

If not charging constantly

• You can fully charge the toothbrush in approx. 17 hours.
  The charging time may decrease depending on the charging capacity.
• A full charge will supply enough power for approx. 90 minutes use.
• Disconnect the power plug when the charge status lamp turns off.

▶ About storage

The toothbrush can only be stored in a compact size with the main unit guide.

3

1. Slide and remove the main unit guide, and place it on horizontal and stable place.
2. Store the main unit and the brush head.

About the lamp

- The toothbrush may not charge even if the charge status lamp turns on when a charger other than the supplied charger is used.

Before cleaning your teeth

• Recommended ambient temperature for using is 5^ - 35^ .
• Do not allow hair products (e.g., gel or oil) or hand lotion to come in contact with the unit as they may damage its surface.
• Do not forcefully turn the brush head with the brush head attached to the main unit. Doing so may cause the brush head or main unit to become damaged.

▶ About uses and operating modes

Brush head	Use Mode Description
	Brushing (dental plaque removal)	WHITE	Recommended for removing plaque and stain care with normal tooth brushing
		SOFT	Recommended when you feel the white mode is too powerfulRecommended for tongue cleaning
	Caring for gums, inner cheeks	RHYTHM	Recommended for brushing gums or inner cheeks (rhythmical vibration)
	Caring for stains	WHITE	Recommended for intensive care of persistent stains

• Stains refer to coloration on the surface of the teeth due to food and drink such as coffee, wine and tea.
- It is not possible to whiten the color of teeth beyond their original color, yellowing teeth due to aging, or discolored teeth.

▶ About soft start function (For WHITE mode on

The toothbrush will gradually reach the selected speed and vibration approximately 2 seconds after it starts operating.

▶ About 30-second brushing notification timer func

The timer will signal once at 30-second intervals to indicate the brushing time for each part of your mouth. It will signal twice at 2-minute intervals to indicate the recommended total brushing time.

It is important to brush each area in the same sequence and with the same amount of time, every time you brush, to uniformly brush and clean your teeth.

Use the 30-second brushing notification timer function wisely so there will be no missed spot in your mouth.

- Divide your teeth into 4 parts (upper and lower, left and right), and brush one part in order such as “(1) front of the teeth”, “(2) biting plane of the teeth”, and “(3) back of the teeth” spending 30 seconds. Brush the other parts in the same manner, and brush your whole mouth in about 2 minutes.

The brush head of this sonic vibration toothbrush vibrates at a high speed.

Therefore:

- You only need to lightly press the bristles against your teeth for brushing.

When first using this appliance, some may experience a tickling or tingling sensation caused by the high-speed vibrations. The sensation should subside after you use the toothbrush several more times.

Using the toothbrush

1 Place the brush head firmly onto the toothbrush shaft.

• Attaching or removing diagonally or while twisting may cause the brush head or the main unit to become damaged.
• The toothbrush shaft will move when a force is applied. This is required for operation, and is not a malfunction.
• There will be a small gap between the brush head and the main unit.

2 Place the toothbrush in your mouth.

- Apply a small amount of toothpaste to the brush head, if desired, before turning the power on to prevent the toothpaste from spattering.

3 Press the power switch to select the mode.

• Each time you press the power switch, the mode changes. (See page 28.)
- The sound may increase when the brush head is pressed too strongly against the teeth, but this is not a malfunction. Apply the brush head lightly against the teeth.

4 Turn off the main unit when you have finished brushing.

- Turn off the main unit before removing it from your mouth to prevent foam from spattering.

Tips on usage

How to apply/move when brushing your teeth
