• Keep the ambient temperature between -10°C and 45°C while
the device is being charged. Keep the ambient temperature
between -10°C to 55°C for using the device powered by a battery.
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 U8800 when tested for use at the ear
is 0.329 W/kg, and when properly worn on the body is 0.773 W/kg.
The highest SAR value reported to the FCC and IC for U8800H when
tested for use at the ear is 0.34 W/kg, and when properly worn on the
body is 0.79 W/kg.
The SAR limit also adopted by Europe is 2.0 W/kg averaged over 10
grams of tissue. The highest SAR value for U8800 when tested at the
