Low Battery Warnings; Assuming Manual Control - Raymarine LIGHTHOUSE 3 Advanced Operation Instructions

If connection between the Remote controller and UAV is not re-established, your UAV will attempt to
land.

Low battery warnings

Ensure while flying your UAV that you remain aware of the remaining flight time and distance from
your vessel at all times. You must return your UAV to your vessel and safely retrieve it before a low
battery warning occurs. The UAV app will mirror the UAV's primary controller battery state warnings.
• Normal low battery level warning — when the UAV reaches normal low battery level, in addition
to the remote controller's audible and visual warnings a warning is also displayed on your MFD.
You should immediately return the UAV to your vessel and retrieve.
• Critical low battery warning — when the UAV reaches critical low battery level, your UAV will
automatically perform a Return to boat maneuver and attempt to land. It is not recommended
that you allow your UAV to reach critical low battery while in flight, as it could result in damage
or loss of your UAV.

Assuming manual control

The UAV pilot has the ability to take manual control of the UAV at any time. Manual control may be
required for normal in-flight maneuvering or positioning, or in emergency situations. The methods of
assuming manual control are as follows:
• Virtual joysticks will need to be hidden, using the Controls icon before control is returned to
the Remote controller.
• Enabling Sport mode on the UAV's Remote controller at any time will override MFD controls. Fly
with caution, as flight characteristics change in Sport mode.
• In an emergency, unplugging the USB cable from the Remote controller will override the MFD
controls and immediately restore manual control to the Remote controller.
