Head exposure reference


Full specifications. Reported SAR. The context behind your connection.
RF Safe source record retrieved September 12, 2026. Regional specifications and test configurations may differ.
Reported US test values · W/kg averaged over 1 g of tissue
Colors indicate reported SAR ranges, not a safety verdict. Results depend on test configuration and regional model. A lower listed maximum does not guarantee lower everyday exposure. How to read these numbers →
| Hotspot (US) | 1.58 W/kg |
|---|---|
| Product-specific use (US) | 1.22 W/kg |
| Head (EU, 10 g) | 1.05 W/kg |
| Body (EU, 10 g) | 1.58 W/kg |
