Emergency Call
You can use your device for emergency calls in the service area. The
connection, however, cannot be guaranteed in all conditions. You should
not rely solely on the device for essential communications.
Certification Information (SAR)
This device meets guidelines for exposure to radio waves.
Your device is a low-power radio transmitter and receiver. As
recommended by international guidelines, the device is designed not to
exceed the limits for exposure to radio waves. These guidelines were
developed by the independent scientific organization International
Commission on Non-Ionizing Radiation Protection (ICNIRP) and include
safety measures designed to ensure safety for all users, regardless of age
and health.
The Specific Absorption Rate (SAR) is the unit of measurement for the
amount of radio frequency energy absorbed by the body when using a
device. The SAR value is determined at the highest certified power level in
laboratory conditions, but the actual SAR level of the device when being
