The device meets RF exposure guidelines when used against the head or at least 1.5 cm from the body. Ensure any carry case or holder maintains this separation distance and does not contain metal. Network connection quality affects data transfer speed. Follow separation distance guidelines during transmission. General use SAR values are typically lower due to automatic power reduction.
