Instructions for Use

Please refer to the included Instructions for Use for important safety guidelines.

How to Wear

Optimal Area

Place sensor on form fitting shirt within the highlighted zone for highest accuracy of reported sleep position. Before putting on the sensor, turn it upside down to confirm it is on.

Magnetic Clip

The magnetic clip goes behind the shirt in any orientation. The sensor must be worn with the logo as shown. There is also a small ridge at the top of the sensor to help you position it correctly in the dark.

Avoid Loose Fitting Shirt

If the sensor is attached to a loose shirt, it can inadvertently fall into a back position causing it to issue vibrational alerts.

Helpful Tips

Adjusting Alert Level

In the Pregnancy Coach App, tap on Menu and then Vibration Settings. Here you can configure how vibrational alerts should be issued separately during the day and at night. You can also vary the starting vibration strength (vibrational alerts gradually increase in strength and duration until you turn away from the back position).

Check Your App for Previous Nights Stats

It's very important to frequently check the Dashboard (the main screen) in the Pregnancy Coach app to be sure the app is syncing with the sensor. Important alerts based on last night's sleep data from the sensor are also shown at the top of this screen. In the Trends tab, you can also see how your position and sleep quality is changing over days, weeks or months.

Wear a Form-fitting Shirt

The Pregnancy Coach Sensor should be worn as much as possible during the night. It can also be worn during the day for users who spend a lot of time in bed or couches where they might frequently recline. Always put the sensor on a tight fitting garment in the area shown. If it’s loose or placed elsewhere, the sensor may not identify your body position correctly.

Adhesive Option

As an alternative to clipping the sensor to a form-fitting shirt, you can attach it at the top of your belly using our adhesive patches. Our medical-grade silicone adhesive patches are easy to apply and leave no residue. First remove the paper flaps and apply the patch to the back of the sensor. Then remove the clear plastic layer and press the sensor to lotion-free skin for 10 seconds.

Charging Your Sensor

You should try to charge the sensor for at least 30 minutes every day.

You may charge the sensor with any standard 5V Micro USB mobile phone charger as well as the one included with the Pregnancy Coach Sensor.

There is no danger in over-charging the sensor so it may be left connected to a charger when not in use. Whenever the sensor is not being worn, it is best to leave it plugged into the charger.
