Hello,
I'm not 100% sure, but I believe,
The single GREEN blink is indicating ( you are in GPS MODE )
The 2 RED blinks, indicate ( weak GPS signal ) 5 satellites
Then
The single GREEN blink ( GPS mode ) same as above
The single RED blink ( ok GPS SIGNAL ) 6 satellites
Ultimately you want a single GREEN blink ( GPS MODE ) with MORE than 6 satellites.( no RED blink )
Maybe another member can confirm! I read the manual, this seems correct!
I have a P2V, mine is a bit different, but I like to read all the manuals to different
Models, like to know as much as possible!
Hope this helps!
