    What is the best thing to do when I lose GPS lock?

    Ideally, I suppose I should learn to fly the thing in non-GPS mode. However, I don't see any way to intentionally get into non-GPS mode. It seems to fly the same way regardless of where the S1 switch is set--and that is in GPS mode. So, how do I learn to fly in non-GPS mode?

    Given that I can't fly well at all in non-GPS mode, what is the best thing to do if I lose contact with the satellites?

    No seriously, you have to enable Naza mode if you want to turn GPS off.

    I'm no EXPERT, to the best of my knowledge
    Should go like this.

    ( I'm using DEFAULT OR FACTORY Settings )
    These toggles can be personalized, to do different things,
    I'm going by what it would be set to out of the box or default!
    ( using the latest firmware ) I'm not sure that matters?

    Always SWITCH BOTH TOGGLES UP, before turning transmitter. ( Tx. ) to ON.
    ( left switch is IOC ( Intelligent orientation control )
    ( right switch is Flight Mode )
    LEFT switch UP is OFF position
    RIGHT switch UP is GPS Normal Mode

    THEN START PHANTOM. ( 1) controller, 2) range extender , 3) phantom, and 4 smart phone app/wifi hook up
    Lift off

    now once in the air, SWITCH RIGHT toggle to MIDDLE position,
    This setting is GPS-ATTI mode ( this setting still uses GPS, but relies LESS on GPS, and MORE on user input ( You )
    GPS NORMAL relies MORE on GPS less on user input!
    ( bottom function or toggle down ( return home feature )

    This way you will be flying more, GPS less. ( right toggle MIDDLE )

    If you lose GPS, DO NOT PANIC, give it a bit to reestablish GPS LOCK! ( mine loses signal occasionally as we'll )

    When you lose GPS, it will feel like ( GPS-ATTI ) mode, with a bit of drifting, up and down movement, and such, still easy to control, if you do ever get concerned, just land, turn off motors , wait till signal is regained, and lift off again, but remember, both toggles up upon liftoff, then change, don't land because GPS signal lost, and forget you are still in ( GPS-ATTI ) mode, and then lift off again, without changing them! I'm not sure why this is? But many have warned about lifting off in any other mode?
    Maybe a professional here can shed a bit more light on this?

    Ps: just so you know
    LEFT toggle:
    Up= OFF
    MIDDLE= Corse Lock
    Down= Home lock
    ( corse lock= this means whichever way your phantom is facing, with corse lock on, forward will be AWAY from you, even if the phantom camera is facing you ( it will fly backwards, although you are pushing up on the stick, another example: say the phantom is sideways from you facing your left ( you looking at the SIDE of the phantom ) you press up, the phantom will fly right ( sideways AWAY from you, I knows forward is AWAY, so whatever direction it is facing? It will fly away from you ( when I say FLY AWAY FROM YOU, I mean direction ( NOT FLY-a-way! ( forever ))
    Toggle DOWN:
    This is HOME LOCK:
    I'm not 100% sure, but I think if you switch the LEFT toggle 8-10 times ( same as you would do on RIGHT TOGGLE for compass cal )
    It will RESET your home point!
    ( NEVER DO THIS IN FLIGHT ) try to reset home point in flight!
    Always perform this action BEFORE TAKEOFF, or land ,reset, and take off again!
    ( again this is how I took it, but I think I'm right. )
    If any of this is incorrect, please feel free to correct me! )
    Hope this helps

    I believe in NAZA-m mode, ( PC assistant ) you can probably do a lot more, like he replied above , turn GPS off?
    I have never messed with NAZA-M BEFORE, so I cannot offer assistance there!

    Jerry what you describe above as factory defaults is actually NAZA-M mode!! The IOC controls on S2 are only available in NAZA. I am wondering if yours came out of the box already in NAZA?

    As far as flying non-GPS, in Phantom2 or NAZA mode, when you are already in the air, switch S1 to the middle position. This will put you in what's called ATTI mode (non-GPS). Practice flying like this on purpose in case you do lose sats. Also the copter will default to this mode if sats are lost and S1 is up.

    One thing I would add to all that goodness you said, BE CERTAIN YOU HAVE GPS HOME POSITION ESTABLISHED BEFORE LIFTING OFF. In Phantom2 mode this is indicated by a set of rapid flashing greens. In NAZA mode, this is indicated as the second set of rapid flashing greens.
