Prysm iO

1. Ensure your Prysm iO is charged, turned on, and near your phone.

2. Ensure the Bluetooth® wireless connection on your phone/tablet is on.

3. Ensure the Bluetooth wireless connection is enabled for the Nu Skin Prysm iO app by going into your phone settings.

4. If you still cannot find your device, it may be paired with another phone/tablet. You can reset the device by doing the following:

Conduct a Factory Reset: Plug your Prysm iO device into the charger. Press and hold the power button for 10 seconds. The LEDs will all flash 3 times.

Note: After a Factory Reset is conducted, your device will need to be paired and set up in the Nu Skin Prysm iO app before you can use it again.

Check the bottom of the Prysm iO to find its serial number. The last 4 digits of the

serial number correspond with the device’s advertising name as it appears in the

Nu Skin Prysm iO app.

Your device may need to be calibrated, which can be done quickly and easily in the Prysm iO app.

• Make sure the Prysm iO lens is free from any dirt or grime by using the provided microfiber cloth.

• Scoring variability is inherent in scientific measurement. Small to moderate variation in a reading like Prysm iO is normal, even in highly controlled laboratory conditions. Excessive variation is likely the result of user inconsistency or other poor scanning practices. Follow the directions in the Prysm iO manual and Best Practices guidelines (below) for the most consistent scanning results.

• All electronic devices change slightly over time, and in some cases Prysm Score variations can occur due to these changes. If you notice variation in your score still exists even when following Best Scanning Practice guidelines (below) then try recalibrating your device (refer to calibration instructions in the app). If this does not resolve the issue, contact customer support. 

• Some devices may become compromised or damaged over time, and this can also cause variation. Contact customer support if this happens to your device.

When your device is connected to the app, your app will automatically sync your data to our secure cloud system after each scan so that you can access your scan history even after reinstalling the Nu Skin Prysm iO app. It is important to make sure you connect your phone/tablet to the internet periodically with the app open so that it can sync your scans. If you remove the app before syncing recent scans to the cloud, some scan data may be lost.

Your Prysm iO device will save scans that are done while not connected to the Prysm iO app. Make sure to periodically sync your Prysm iO device with the app to ensure that all your scans are uploaded and saved.

For best practices, you should recalibrate your device about once a month to ensure it is performing optimally. You will also receive notifications in the Nu Skin Prysm iO app when your device needs to be recalibrated.
