Commission on Non-Ionizing Radiation Protection (ICNIRP),
an independent scientific organization, and include safety
measures designed to ensure the safety of 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 during operation 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 Europe is 2.0 W/kg averaged over
10 grams of tissue, and the highest SAR value for this device
complies with this limit.
HUAWEI Y635–L01:
The highest SAR value reported for this device type when
tested at the ear is 0.481 W/kg, and when properly worn on
the body is 0.806 W/kg.
HUAWEI Y635-L02:
The highest SAR value reported for this device type when
tested at the ear is 0.481 W/kg, and when properly worn on
the body is 0.653 W/kg.
HUAWEI Y635-L21:
The highest SAR value reported for this device type when
