Press the central button to view the time and then your progress towards your daily target. Once the time is displayed, your progress is shown by the 12 indicator lights. When four indicator lights are alight, you are at 25% of your target. When six indicator lights are alight, you are at 50% of your target.
Your ONcoach 100 lets you record other sports practices than everyday walking.This mode lets you measure the duration of your sports session and the calories consumed.
For walking and running, it will also measure average speed and distance.
To start recording a sports session, press the central button twice.
Two indicator lights rotating clockwise indicate that recording has started.
To stop recording, press the button twice.
Two indicator lights rotating anticlockwise indicate that recording has stopped.
Press the central button to view the time and then your progress towards your daily target. Four indicator lights show the quarter-hours. One indicator light shows the time, and another flashes to show the minutes.
Your ONcoach 100 measures your sleep automatically. For the measurement to be taken, you must wear it while you sleep. Our algorithm detects the time you go to bed, the time when you wake up and the different phases according to your movements at night.
When workout mode is activated, your ONcoach 100 cannot measure your sleep.
To pair your ONcoach 100 with the application for the first time:
You will be asked to configure your step and sleep targets the first time you start the ONcoach application. If you want to change these targets later, you can do so by going to the"my target" menu on your application.
When synchronising your ONcoach 100 with the application, you will have to identify the sport practised for each recorded sports session.

Your ONcoach counts your paces when you are pushing a pushchair, but the number of paces counted may be lower, because your arms do not move.
The algorithms of your ONcoach 100 have been developed to not count steps when you are in your car, in a bus or another means of transport. It is possible, however, that the vibrations emitted by the vehicle generate additional steps.
The algorithms of your ONcoach 100 have been developed to count steps only during walking activities.
However, additional steps may be counted when you perform movements at frequencies close to that of walking.
The ONcoach 100 has been tested on a sample of more than 90 people walking or running at a comfortable speed.
The error detected on the number of steps when running was +/- 3% for 68%. It was higher for the rest of users.
The error detected on distance when running was +/- 15% for 68%. It was higher for the rest of users.
To improve the accuracy of distance measurement when running, you can calibrate it from the application in the “My ONcoach 100" /"Calibrate my ONcoach 100" menu.
There are two light sleep phases.
Cycle 1: In the first 7 minutes, you are in a phase of light sleep. Your eyes try to stay open and your muscles start to relax.
Cycle 2: You then enter the second phase of light sleep, in which your body becomes relaxed and gets ready to dream.
There are also two light deep phases.
Cycle 3 (slow wave sleep): this phase lasts between 20 and 40 minutes, and allows the body to relax.
Cycle 4 (paradoxical sleep): this is the phase when we dream. It enhances the brain's functions and allows for the creation of memories.
Restorative sleep is characterised by an increase in the length of paradoxical sleep as the night progresses. It gradually replaces the cycle 3.
The ONcoach 100 has been tested on a sample of more than 100 people, walking or running at a comfortable speed.
The error detected on the number of steps when walking was +/- 6% for 68%. It was higher for the rest of users.
Nevertheless, when you make other movements with your arms, the ONcoach 100 may count some extra paces.
Your ONcoach 100 calculates the distance using an algorithm developed by our research and development team.
If you think that the distance is wrong, you can change the pace length in the"My ONcoach 100/Calibrate my ONcoach 100" menu in the application.Calibration only works for running.
Yes, any sleep is detected and measured by your ONcoach 100, irrespective of the time of day.
The ONcoach 100 can be used for six months under normal conditions.
Since it uses a battery, its lifetime depends on the use, and in particular on the frequency of synchronisation with the application and the display of the indicator lights.
To replace the battery of the ONcoach 100, turn the battery cover to the left and remove it.
Gently pull the black tab to extract the battery.Insert the new battery, while making sure that the positive pole is towards the bottom of the battery cover.
Close the battery cover by placing the 2 triangular indicators face to face and making sure to reposition the tab on the battery.
Push the cover until it closes properly.
Turn it to the right until the triangular indicator is vertical.
Synchronize your ONcoach 100 with the application to reset the correct time.
If the LED display is weak or missing, the battery level may be low.
You can check the battery level from the application in the"My ONcoach 100" /"Information" menu.
It is advisable to change the battery when you notice this kind of display problem.
The ONcoach 100 is 3 ATM waterproof, which means that you can wear it in the shower and that it withstands perspiration, rain and splashes.

When the workout mode is activated (recording a sport session), the data cannot be transferred to your smartphone and the time and your target gauge cannot be viewed. When you press the button, an indicator light (four lights in the shape of a cross) informs you that you are in workout mode.
Your ONcoach 100 can record up to 30 days of data.
It is however advisable to frequently synchronise your ONcoach 100 with the ONcoach application to optimise the transfer time.
In workout mode you can record the start and the end of a sport session. You can then retrieve the session in the ONcoach application. The application will ask you to select one of more than 40 sports. You can then view the length of the session and the calories consumed. For walking and running, you can also view the distance and the average speed.
