Initial GPS connect If the meter does NOT detect an incoming GPS signal, it will flash steadily for 10 seconds and then glow steadily once it gets into Measurement mode. If it does detect the GPS signal (satellites found etc..), it gives a series of 3 rapid flashes before going to the steady glow for Measurement mode.
