4.4 Summary SAR test Plan for Proximity sensor power reduction
For Body SAR compliance, the device uses proximity sensor power reduction for
some frequency bands of Main antenna and test positions. To ensure all production
units are compliant, the smallest separation distance determined by the sensor
triggering and sensor coverage for normal and tilt positions for each applicable side
and top triggering conditions, minus 1 mm, is used as the test separation distance for
SAR testing. These SAR tests are included in addition to the SAR tests for the device
touching the SAR phantom with reduced power.
