Use the antenna
Your phone has a built-in antenna. As 
with any other radio transmitting device, 
avoid touching the antenna while the 
phone is powered up.
Contact with the antenna affects call 
quality and may cause the phone to 
operate at a higher power level than 
necessary. Hold the phone as you would 
any other telephone with the antenna 
area pointed up and over your shoulder.
