Braun Oral-B Smart Guide Display Versions

In this article we explain the different models and sub-versions of each of the Braun Oral-B wireless Smart Guide displays, to complement our Smart Guide repair page.

The Smart Guide display units were supplied with various models of Braun Oral-B electric toothbrush and allow the user to keep track of their brushing progress throughout each brushing session. Two main models of Smart Guide exist, the squarer Type 3741 and the more rounded Type 3742. Each type has several variants and offers compatibility with different models of toothbrush.

Type 3741

Smart-Guide-3741-Braun-Oral-BThe Type 3741 Smart Guide from Braun Oral-B is the original model and comes in at least 4 different sub-versions, each with slightly different icons and features.

The Pulsonic Smart Guide displays a diagram of a toothbrush with a tall narrow brush head attached. It shows no stars on the screen and the colour of the rubber seal on the back of the Smart Guide is unknown at present. Please leave a comment below if you have one of these and can tell us which colour the seal is. Once brushing is completed it will show a smiling face 🙂

Up to two separate Pulsonic toothbrushes can be synchronized with the Pulsonic Smart Guide so see the ‘Pairing’ section lower down for instructions.

It is possible that the 4 star Type 3741 Smart Guide can be substituted with version A of the 3742 Smart Guide as that display was also supplied with the Type 3762 Triumph toothbrush. Two separate toothbrushes can be paired with this Smart Guide at once so see our synchronizing instructions lower down the page for how to do this.

Type 3742

Only available in white, version B of the 3742 is also known as the 2.1 version and will work with the Genius/Smart range of toothbrushes marked with Type 3765 on the toothbrush handle. You might need to enable the Smart Guide functionality on the toothbrush itself via the smartphone app before the brush will synchronize with the Smart Guide.

Where to Buy a Replacement Smart Guide

The only Smart Guide units still available brand new are of the 3742 type. For a 3741 you will end up buying a pre-owned one. If you find that you can’t repair your current Smart Guide then the best place to find a replacement new or used Smart Guide is through the listings linked to below on eBay. Make sure you choose one of the same variant as your current Smart Guide as the different sub-versions are not interoperable and the wrong variant will not work with your toothbrush.

Don’t forget that you might need to ‘pair’ or synchronize your new SmartGuide with your toothbrush when it arrives. See the next section for synchronizing instructions.

Synchronizing your Smart Guide with your Toothbrush (Pairing)

Your Smart Guide can be synchronized (also called pairing or programming) to work with one or two Braun Oral-B toothbrushes at the same time, as long as both these brushes are of the same Type number.

Setup & Clock

To power up your SmartGuide slide open the battery cover on the back and insert two fresh Alkaline batteries (AA size for the Type 3741, AAA size for the Type 3742 SmartGuide). The clock display should start flashing ’12:00′.

Press and hold the ‘set’ button inside the battery compartment until ’12h’ is flashing in the display. This means that time will be displayed in the 12-hour format. If you would prefer 24-hour time format press the  ‘h/min’ button once so that ’24h’ is displayed. Press ‘set’ to save the setting.

The hours digits should now be flashing. Keep pressing the ‘h/min’ button until the correct hour is showing and press ‘set’ to save the setting.

The minutes digits should now be flashing. Keep pressing the ‘h/min’ button until the correct minute is showing and press ‘set’ to save the setting.

Synchronizing

  • Open the battery compartment of your Smart Guide and hold down the ‘h/min’ button for 3 seconds until the display starts flashing ‘L ‐ ‐ ‐’
  • Switch on your toothbrush for a few seconds until the SmartGuide displays ‘L ‐ 1 ‐’
  • Switch off your toothbrush
  • If you have a second matching toothbrush to pair with the SmartGuide switch it on now and let it run for a few seconds until the SmartGuide displays ‘Full’
  • You can exit the pairing process by pressing either button inside the battery compartment.

Some toothbrushes have the facility to turn off radio transmission so if this has been used the toothbrush will be unable to pair with the Smart Guide.
