C78 User Manual 

 

16 

For optimum performance with minimum power consumption, do not cover the antenna 
area (It’s on the bottom of your phone.) with your hand. Covering the antenna affects 
the call quality, may cause the handset to operate at higher power levels than needed, 
and may shorten talk and standby times. 

Your handset is a low-power radio transmitter and receiver.  When it is turned on, it 
intermittently receives and transmits Radio Frequency (RF) energy in radio waves to 
handle and control the power level at which the handset transmits. Exposure to radio 
frequency energy: 
  Radio wave exposure and Specific Absorption Rate (SAR) information. The 

handset is designed to comply with safety 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.
