About this product
The Black Sonicare 1100 with one C1 head
This Philips Sonicare 1100 Series selection is the Black HX3641/03, UPC 075020112545. The set contains one rechargeable toothbrush handle, one C1 SimplyClean brush head and one USB charging stand. A power adapter is not included. The C1 head has Soft, flexible bristles. Match the model and these included components when comparing Sonicare sets, since extra heads and wall adapters are separate package details.
Timing prompts for four sections of the mouth
SmarTimer completes the brushing cycle after two minutes by turning the toothbrush off. QuadPacer gives a prompt every thirty seconds to move to another section of the mouth. Together, the features divide the two-minute routine into four timed sections. Keep directing the head around the teeth during each section; the timer tracks the interval rather than assessing whether every tooth has been brushed.
A gradual introduction to sonic brushing
EasyStart gradually increases brushing power over the first fourteen uses to help with the transition to sonic brushing. The rechargeable handle provides up to fourteen days of regular brushing on a full charge, based on two two-minute sessions per day. That is a conditional battery-life figure, rather than a promise of fourteen days with any brushing frequency or session length.
Clean the head, handle and stand appropriately
Rinse the brush head and bristles after each use and allow them to air dry. At least weekly, remove the head and rinse its connection with warm water. Remove toothpaste residue around the handle buttons and shaft, wipe the handle with a damp cloth and dry it with a soft cloth. Avoid sharp objects around the rubber seal, and do not tap the handle against the sink to remove water. Unplug the stand before wiping and drying it.
Replacement and precautions for continued use
Replace the head every three months or sooner if wear appears; stop using a head with crushed or bent bristles. Keep charging cables and adapters away from water and dry before connecting power. Do not clean the components in a dishwasher. Stop use and consult a dentist or doctor for excessive or prolonged bleeding, discomfort or pain. If you have a pacemaker or other implanted device, contact your doctor or its manufacturer before use.

Questions about this product
Is a wall power adapter included?
No. The HX3641/03 set includes the USB charging stand, one Black 1100 handle and one C1 SimplyClean head. Use an appropriate power adapter as directed in the supplied Philips instructions. Keep charging cables and the adapter away from water and completely dry before connecting power.
How do SmarTimer and QuadPacer differ?
SmarTimer turns the brush off after the two-minute brushing cycle. QuadPacer prompts a move to another mouth section every thirty seconds. EasyStart serves another purpose: it increases brushing power gradually over the first fourteen uses to help introduce sonic brushing.
Does fourteen-day battery life apply to any routine?
The stated maximum is up to fourteen days based on two two-minute sessions per day after a full charge. More frequent or longer use changes that basis. The handle is rechargeable on its included USB stand; the package does not supply disposable AAA batteries.
How often should the C1 head be replaced?
Replace the head every three months or sooner when signs of wear appear. Stop using crushed or bent bristles. Rinse the head after each use and let it air dry, and rinse the detached head connection with warm water at least weekly.
