Enhanced 911 (E911) Information
This device features an embedded Global Positioning 
System (GPS) chip necessary for utilizing E911 
emergency location services where available. 
When you place an emergency 911 call, the GPS 
feature of your device seeks information to calculate 
your approximate location. 
Note: Depending on several variables, including availability and
access to satellite signals, it may take up to 30 seconds 
or more to determine and report your approximate 
location.
Important!: Always report your location to the 911 operator when
placing an emergency call. Some designated 
emergency call takers, known as Public Safety 
Answering Points (PSAPs) may not be equipped to 
receive GPS location information from your device.
