RC Signal Management
Always use the controller as a primary or backup control system when flying.
Ensure that the controller is turned on any time IRIS-M is powered. Flying
behind solid objects, like buildings and trees, blocks radio signals. Always
maintain visual contact with the copter to ensure that the radio signal is
unobstructed. Radio towers, cell phone towers, and nearby WiFi signals can
also cause interference with the radio system and decrease its range. Avoid
flying in populated areas to avoid sources of interference. If contact with the
controller is lost during manual flight, IRIS-M returns to the launch point
automatically. (See page 18 for more information about RTL.) If the controller
signal is lost during a mission, IRIS-M continues with the mission.
GPS Management
IRIS-M requires an active GPS signal for AUTO (missions), LTR, and RTL. If
IRIS-M loses GPS signal in flight, it lands at the current position, indicated by a
blinking blue and yellow LED with a high-high-high-low tone. Always choose
an unobstructed flying area to improve GPS signal strength.

Emergency Recall
If IRIS-M moves outside your designated flying area or displays instability in
flight, initiate a recall command by selecting RTL or land using the controller.
See pages 17 and 18 for more information on these commands.
Regaining Manual Control
Always be prepared to regain manual control of IRIS-M at any time while flying
in AUTO mode. To switch to manual control during a mission, switch the mode
on the controller from AUTO to LTR (recommended) or STD mode. See page
13 for manual fight control instructions.
