 
Antenna
Your device may have internal and 
external antennas. As with any radio 
transmitting device, avoid touching 
the antenna area unnecessarily 
while the antenna is transmitting 
or receiving. Contact with such an 
antenna affects the communication 
quality and may cause the device to 
operate at a higher power than otherwise needed and may 
reduce the battery life.
An internal GPS antenna is activated when you place an 
emergency call or select 
Location On
from the
Location
menu.
See "Location," p. 67.
Any GPS should not be used for precise location measurement, 
and you should never rely solely on location data from the GPS 
receiver and cellular radio networks for positioning or navigation.
