Your Philips Sonicare toothbrush is safe to use on:
- Braces (brush heads wear out sooner when used on braces)
- Dental restorations (fillings, crowns, veneers)
Note: When the Philips Sonicare toothbrush is used in clinical studies, it must be used in the Clean mode (for plaque and gum health claims) or in White mode (for whitening claims) at high intensity with EasyStart turned off.
Features
- EasyStart
- Brush head replacement reminder
- Pressure sensor
- Quadpacer
EasyStart
This Philips Sonicare model comes with the EasyStart feature activated. The EasyStart feature gently increases the power over the first 14 brushings to help you get used to the brushing with the Philips Sonicare. The EasyStart feature works in all modes.

natural_image
Simple diagram with a starburst shape and a small circle below, no text or symbols presentTo deactivate EasyStart see 'Activating or deactivating features'.
Brush head replacement reminder
Your Philips Sonicare is equipped with BrushSync technology that tracks the wear of your brush head.
1 When attaching a new smart brush head for the first time the brush head replacement reminder light blinks green three times. This confirms you have a Philips brush head with BrushSync technology.
2 Over time, based on the pressure you apply and the amount of time used, the handle will track brush head wear in order to determine the optimal time to change your brush head. This feature gives you the guarantee for the best cleaning and care of your teeth.
3 When the brush head replacement reminder light lights up amber, you should replace your brush head.
To deactivate the brush head replacement reminder see 'Activating or deactivating features'.
Pressure sensor
Your Philips Sonicare is equipped with an advanced sensor that measures the pressure you apply while brushing. If you apply too much pressure, the toothbrush will provide immediate feedback to indicate that you need
to reduce the pressure. This feedback is given by a change in vibration and therefore brushing sensation.
To deactivate the pressure sensor see 'Activating or deactivating features'.
Quadpacer
The Quadpacer is an interval timer that has a short beep and pause to remind you to brush the different sections of your mouth.
Depending on the brushing mode you have selected (see 'Brushing modes'), the
Quadpacer beeps at different intervals during the brushing cycle.

Disposal

text_image
RECYCLE RBRC 1.800.822.8837This appliance contains a rechargeable battery which must be disposed of properly. Contact your local town or city officials for battery disposal information. You can also call 1-800-8-BATTERY or visit www.rbrc.com for battery drop-off locations.
For assistance, visit our website www.philips.com/support or call 1-800-243-3050 toll free.
Removing the rechargeable battery
Warning: Only remove the rechargeable battery when you discard the appliance. Make sure the battery is completely empty when you remove it. Any attempt to remove the battery will void the warranty.

- To remove the rechargeable battery, you need a towel or cloth, a hammer and a flat-head (standard) screwdriver. Observe basic safety precautions when you follow the procedure outlined below. Be sure to protect your eyes, hands, fingers, and the surface on which you work.
1 To deplete the rechargeable battery of any charge, remove the handle from the charger, turn on the Philips Sonicare and let it run until it stops. Repeat this step until you can no longer turn on the Philips Sonicare.
2 Remove and discard the brush head. Cover the entire handle with a towel or cloth.
3 Hold the top of the handle with one hand and strike the handle housing 0.5 inch above the bottom end. Strike firmly with a hammer on all 4 sides to eject the end cap.
Note: You may have to hit on the end several times to break the internal snap connections.
4 Remove the end cap from the toothbrush handle. If the end cap does not release easily from the housing, repeat step 3 until the end cap is released.

If the internal components do not easily release from the housing, repeat step 3 until the internal components are released.
6 Wedge the screwdriver between the battery and the black frame at the bottom of the internal components. Then pry the screwdriver away from the battery to break the bottom of the black frame.
7 Insert the screwdriver between the bottom of the battery and the black frame to break the metal tab connecting the battery to the green printed circuit board. This will release the bottom end of the battery from the frame.
8 Grab the battery and pull it away from the internal components to break the second metal battery tab.
Caution: Be aware of the sharp edges of the battery tabs so as to avoid injury to your fingers.
9 Cover the battery contacts with tape to prevent any electrical short from residual battery charge. The rechargeable battery can now be recycled and the rest of the product discarded appropriately.
