13 1.1.1.1.1 Radio wave exposure and Specific Absorption Rate (SAR) information Exposure to radio frequency energy

The handset is designed to comply with safely, requirements for exposure to radio waves. This requirement is based on scientific guidelines that include safety margins designed to assure the safety of all persons, regardless of age and health. The radio wave exposure guidelines employ a unit of measurement known as the Specific Absorption Rate, or SAR. Tests for SAR are conducted using a standardized method with the phone transmitting at its highest certified power level in all used frequency bands.

While there may be differences between the SAR levels of various ZTE phone models, they are all designed to meet the relevant guidelines for exposure to radio waves. The SAR limit recommended is 1.6W/kg averaged over one(1) gramme of tissue. The highest SAR value for this model phone tested by MORLAB for use at the head is 0.940 W/kg(1g) The highest SAR value for this model phone tested by MORLAB for use at the body is 0.388W/kg(1g) SAR compliance for body-worn operations is restricted to belt-clips, holsters, or similar accessories that have no metallic component in the assembly and

14 which provide at least 1.5 cm separation between the device, including its antenna, and the users body Aircraft Safety
