The Chk GPS (Check GPS) function forces the
device to turn on its GPS receiver and to
continuously update and display GPS data in

user leaves this screen by tapping the Back

environment; e.g., in dense foliage or around urban settings with tall buildings.
Satellites are monitored in real-time to make sure there are at least 4 in range, at
