The Specific Absorption Rate (SAR) is a value commonly used to quantify the hazards of human body exposure to radio frequencies (RF) from electronic devices.

ScanWatch is an electronic device that works with Bluetooth and is safe to wear. Let us explain why:

The SAR limit value is 2.0 watts per kilogram (W/kg), or 2000mW, in European Union and 1.6 W/kg, or 1600mW, in the United States.

The maximum power of ScanWatch is 0.6mW, and therefore does not exceed the applicable RF exposure limits of 2000mW.

Manufacturers whose products emit very little (less than 20mW) are exempt from the display and calculation rules, which is why the SAR is not displayed on Withings communication media.

Note: The Bluetooth connection is not necessary at all times for the watch to work. You ScanWatch can keep data in memory if you would rather like to sync it manually. To do so, open the Health Mate app and turn the Bluetooth of your mobile device on. When you do so, your ScanWatch automatically syncs your data with the app.

Please, keep in mind that your ScanWatch has limited memory. Make sure you sync your data regularly so that you do not lose any of them.
