4.1 Overview

Specific absorption rate (SAR) is a measure of the rate at which energy is absorbed
by the body when exposed to an RF electromagnetic field. It is commonly used to
measure power absorbed from mobile phones. The greater the SAR value, the
greater the radiation effect on humans.
For user equipment (UE) such as modules, their SAR value increases as their
transmitted power increases.
At present, most vendors' tablets have passed SAR tests. Generally, these products
have embedded proximity sensors. When the sensors detect that a human is in the
proximity of or in contact with the UE, they will notify the UE so that the UE will
reduce the transmitted power. When the human is no longer in the proximity of or in
contact with the UE, the sensors also notify the UE so that the UE will restore the
transmitted power.

4.2 Enabling/Disabling BodySAR

4.2.1 Reference Process

Command
AT^BODYSARON=1
OK
AT^BODYSARON=0
OK
If the BodySAR feature is enabled, the maximum transmitted power can be adjusted.
If the BodySAR feature is disabled, the system's default maximum transmitted power
is used.
