battery is affected.
• Do not place sharp metal objects such as pins near the earpiece. The earpiece may
attract these objects and hurt you when you are using the device.
• Before you clean or maintain the device, power off the device and disconnect it
from the charger.

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
