Electrostatic discharge can interfere with the normal functioning of
electronic devices. Your smartphone can behave abnormally owing to
such an event, resulting in the possible loss of unsaved data. To
recover, reset your smartphone in accordance with the instructions in
this User's Guide.
To avoid losing data due to electrostatic discharges or other types of
events, it is recommended that you regularly save and backup your
data as described in this User's Guide.
RADIO FREQUENCY (RF) EXPOSURE AND SAR
Your smartphone is a low-power radio transmitter and receiver. When
it is turned on, it emits low levels of radio frequency energy (also
known as radio waves or radio frequency fields).
Governments around the world have adopted comprehensive
international safety guidelines, developed by scientific
organizations*, e.g. ICNIRP (International Commission on Non-
Ionizing Radiation Protection), through periodic and thorough
evaluation of scientific studies. These guidelines establish permitted
levels of radio wave exposure for the general population. All
Ericsson mobile phone models are designed to operate within these
stringent levels. The levels include a safety margin designed to assure
the safety of all persons, regardless of age and health, and to account
for any variations in measurements.
Specific Absorption Rate (SAR) is the unit of measurement for the
amount of radio frequency energy absorbed by the body when using a
mobile phone. The SAR value is determined at the highest certified
power level in laboratory conditions, but the actual SAR level of the
phone while operating can be well below this value.
This is because the phone is designed to use the minimum power
required to reach the network. Therefore, the closer you are to a base
station, the more likely it is that the actual SAR level will decrease.
Variations in SAR below the radio frequency exposure guidelines do
not mean that there are variations in safety. While there may be
differences in SAR levels among mobile phone models, all mobile
phone models must be designed to meet radio frequency exposure
guidelines.
