The Smart Guide display units were supplied with various models of 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 3742
The Type 3742 Smart Guide from Oral-B is the newer model and comes in at least 2 different versions. Unfortunately the different versions are not interoperable so if you are looking for a replacement Smart Guide to work with your electric toothbrush use our guide below to determine which version of 3742 Smart Guide you have. Available in white and silver, this Smart Guide is powered by two AAA size batteries and we recommend that only Alkaline batteries are used, not zinc ones.
Version A
Version A of the Type 3742 Smart Guide has a letter A at the end of the string of numbers marked inside the battery compartment on the ridge between the two batteries. This version was supplied with Oral-B toothbrushes marked with Type 3762 on the bottom of the handle.
Version B / Version 2.1
Version B of the Type 3742 Smart Guide has a letter B at the end of the string of numbers marked inside the battery compartment on the ridge between the two batteries.
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.

The Smart Guide is a separate LCD unit powered by two AAA batteries (included in the box).
At a glance the Smart Guide communicates which brushing mode you are using, when the time comes to brush a different section of your mouth as well as if you are brushing too hard.

After two minutes of brushing a smiley face appears on the screen. If user stop brushing earlier they are awarded with a star rating (out of five) on the screen. The star rating turned teeth brushing into somewhat of a competition, with user aiming to get as many stars as possible.
When you are not brushing your teeth, the Smart Guide displays the current time as well as the star rating of your last brushing session.
It is also worth mentioning that the Smart Guide is basically the only reliable way to determine which brushing mode you are using. If you are someone who makes use of the different brushing modes then you may find yourself relying on it.

Synchronizing your Smart Guide with your Toothbrush (Pairing)
Please note that you might need to ‘pair’ or synchronize your new SmartGuide with your toothbrush when it arrives.
Note : 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 (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.
