• Before you clean or maintain the device, power off the device and disconnect it
from the charger.
• Do not use any chemical detergent, powder, or other chemical agents (such as
alcohol and benzene) to clean the device and the charger. Otherwise, parts of the
device may be damaged or a fire can be caused. You can clean the device and
the charger with a piece of damp and soft antistatic cloth.
• Do not dismantle the device or accessories. Otherwise, the warranty on the
device and accessories is invalid and the manufacturer is not liable to pay for the
damage.
• 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.
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 at the ear is 0.786 W/kg, when properly worn on body
is 1.240 W/kg, and when using Wi-Fi hotspot function is 1.240 W/Kg.
