Getting started
Installing or replacing batteries 

 1 

 Remove the battery compartment cap from 

the bottom of the handle by pulling on the 

grips (Fig. 2).

 2 

 Insert two AA 1.5 volt batteries into the 

handle. Make sure the + and - poles of the 

batteries match the indication on the inside of 

the handle (Fig. 3).

 3 

 Firmly push the battery compartment cap 

back onto the handle (Fig. 4).

Attaching the brush head

 1 

 Align the front of the brush head with the 

front of the toothbrush handle. 

 2 

 Push the brush head onto the shaft.  (Fig. 5)

User ID sticker

If you have multiple Sonicare battery 

toothbrushes in your home, you can attach the 

white or silver sticker to the battery cap. This 

helps you identify your handle.  (Fig. 6)

Using your Sonicare

 1 

 Wet the bristles and apply a small amount of 

toothpaste.

 2 

 Place the toothbrush bristles against the teeth 

at a slight angle towards the gumline (Fig. 7).

 3 

 Hold the handle with a light grip and turn on 

the Sonicare. Gently move the brush head 

slowly across the teeth in a small back and 

forth motion so the longer bristles reach 

between your teeth. Continue this motion 

throughout your 2-minute brushing cycle.

 4 

 To maximize effectiveness, apply only light 

pressure and let the toothbrush do the 

brushing for you. Do not scrub.

 5 

 To make sure you brush evenly throughout 

the mouth, divide your mouth into 4 sections: 

outside top, inside top, outside bottom 

and inside bottom teeth. Begin brushing in 

section 1 (outside top teeth) and brush for 

30 seconds before moving to section 2 (inside 

top teeth). Continue brushing in section 3 

(outside bottom teeth) and brush for 30 

seconds before moving to section 4 (inside 

bottom teeth) for a total brushing time of 2 

minutes (Fig. 8)

 6 

 After you have completed the 2-minute 

brushing cycle, you can spend additional 

time brushing the chewing surfaces of your 

teeth and areas where staining occurs. 

You may also brush your tongue, with 

the toothbrush turned on or off, as you 

prefer (Fig. 9).

   

Your Sonicare is safe to use on:

Braces (brush heads wear out sooner when 

used on braces)

Dental restorations (fillings, crowns, veneers)

Features
Smartimer 2-minute timer

After 2 minutes, the Smartimer automatically 

turns off your toothbrush.

To pause or stop brushing during your 2-

minute cycle, press the power button. Press 

the power button within 30 seconds and the 

Smartimer picks up where you left off.

Battery indicator (select models)

The battery indicator shows the amount of power 

left in the batteries.

Solid green light indicates there are at least 16 

two-minute brushings available (Fig. 10).

Flashing green light indicates there are less than 

16 brushings available.

Sonicare

  

400 Series Battery 

toothbrush

Three beeps at the end of a two-minute 

brushing indicate that there are less than 4 

two-minute brushings available. 

Note: The number of brushings you get from new 

batteries may vary depending on the type of batteries 

you use.
Note: The toothbrush will turn on for one second then 

immediately shut off to indicate it is time to replace 

batteries.

Easy-start 

This Sonicare model comes with the Easy-start 

feature, which helps you get used to brushing 

with Sonicare.

Brushing power gently increases to full power 

over the first 14 brushings.

Note: Each of the first 14 brushings must be at least 

1 minute in length to advance through the Easy-start 

ramp-up cycle properly.
Note: Prior to a clinical test, ensure that the Easy-start 

process has been completed, attach a new brush 

head and install new AA alkaline batteries.

Cleaning 

Do not place brush heads and the handle in the 

dishwasher.

 1 

 Rinse the brush head and bristles after each 

use. Let the brush head air-dry only (Fig. 11).

 2 

 Remove the brush head once a week and 

clean the connection between the brush head 

and the handle.  (Fig. 12)

Do not use sharp objects to press on the rubber 

seal, as this may cause damage. 

 3 

 Clean the remainder of the handle 

periodically with mild soap and a moist 

cloth (Fig. 13).

Storage

If you are not going to use the toothbrush for 

an extended period of time (a month or longer), 

remove the batteries, clean the appliance and store 

it in a cool and dry place.

Replacement
Brush head

Replace Sonicare brush heads every 3 months 

to achieve optimal results.

Use only Sonicare HydroClean replacement 

brush heads with the B400 model.

Disposal

Do not throw away the appliance with the 

normal household waste at the end of its life, 

but hand it in at an official collection point for 

recycling. By doing this, you help to preserve 

the environment (Fig. 14).

This symbol represents Philips’ 

recommendation to dispose of your AA 

batteries properly.
