Maintenance
z
If the device is not used for a long time, power it off, and then
remove all the cables connected to it.
z
If any exception occurs, for example, if the device emits any
smoke or unusual sound or smell, stop using the device
immediately, power it off, remove all the cables connected to it,
and then contact an authorized service center.
z
If the device screen is broken by colliding with hard objects, do not
touch or try to remove the broken part. In this case, stop using the
device immediately, and then contact an authorized service center
in time.
z

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 operated can be well below the value. This is
because the device is designed to use the minimum power required
to reach the network.
The SAR limit adopted by USA and Canada is 1.6 watts/kilogram
(W/kg) averaged over one gram of tissue. The highest SAR value
reported to the FCC and IC for this device type when tested for use in
