both receives and emits radio waves. It is intended
to meet all safety requirements pertaining to impact

indicated level. Such discrepancies result from
automatic changes in device power necessary to
ensure that the device operates at a minimum power
level required to be connected with network.
Although SAR values might vary for different models
