Switch on and off
Press and hold the end key.
Use the device only in its normal 
operating position.
Your device has an internal antenna.
Note: As with any radio 
transmitting device, avoid touching an antenna 
unnecessarily when the antenna is in use. For example, 
avoid touching the cellular antenna during a phone call. 
Contact with a transmitting or receiving antenna 
affects the quality of the radio communication, may 
cause the device to operate at a higher power level than 
otherwise needed, and may reduce the battery life.
Note: Do not touch this connector 
as it is intended for use by 
authorized service personnel only.
