# Battery Safety Secure battery inside the guard bag while charging. Charge until the status indicator displays green.

Charging Complete 

# 4

Protect the battery from extreme heat, extreme cold, puncturing, and flammable surfaces. Always transport, charge, and store the battery in the guard bag.

Charge the battery using a designated LiPo balance charger only. Always monitor the battery while charging.

Flying with a low battery is a safety risk and can render the battery unusable. Always discontinue use when you receive a low battery notification, and always fly with a fully charged battery.

Inspect the battery for damage before takeo f and after landing. If you observe any swelling of the package or the battery ceases to function, locate your local battery recycling center to dispose of the battery. In the US and Canada, visit call2recycle.org to find a location. Do not dispose of the battery in the trash.

*Flight time varies with payload, wind conditions, altitude, temperature, humidity, flying style, and pilot skill. See the Flight Checklist for instructions on managing battery levels during flight.07 IRIS has powerful motors and high-speed propellers. Never place your hands near propellers while IRIS is armed or the safety button displays solid red. Always press the safety button until it displays blinking red before handling.

Always fly in an open area away from people and buildings; do not attempt to fly indoors or in a confined space. Do not fly over people, near airports, or in any situation that could pose a hazard to those around you. Always fly within your line of sight and in compliance with local regulations. IRIS will not avoid obstacles on its own. As the operator, it is your job to recognize and avoid obstructions while flying. Always follow the preflight and postflight steps in the order described in this manual, and remain attentive at all times while flying.

Environmental factors, such as wind and GPS irregularities, can cause instability in flight. IRIS will attempt to compensate for these factors by triggering a failsafe if it detects an unsafe flying condition due to loss of controller signal, loss of GPS signal, or low battery (see below for details). To avoid potential hazards due to environmental factors, identify the boundaries of your flying area before takeoff, and recover IRIS manually by switching into standard (STD) if it moves outside your designated flying area. If you observe any inconsistent behavior, land, and consult the troubleshooting guide at 3dr.com/iris/info. 

# Failsafes

Loss of RC signal Always use the controller as a primary or backup control system when flying. Ensure that the controller is turned on any time IRIS is powered. If contact with the controller is lost during flight, IRIS will land and display a blinking yellow LED. If IRIS is more than 2 meters (6.5 feet) from the launch point, it will return to launch (RTL) before landing. (See page 13 for more information about RTL.)

Loss of GPS signal IRIS requires an active GPS signal before takeoff. If IRIS loses GPS signal in flight, it will trigger a GPS failsafe, indicated by a blinking blue and yellow LED with a high-high-high-low tone, and automatically switch to manual control (standard - altitude hold mode). Always be prepared to regain manual control of IRIS at any time while flying and choose an unobstructed flying area to improve GPS signal strength. When flying a mission, we recommended changing the GPS failsafe behavior to land. (Visit 3dr.com/iris/info for more information about configuring the GPS failsafe.)

Low battery When the battery reaches 25% of its remaining charge, IRIS will land and display a blinking yellow LED with a quick repeating tone. If IRIS reaches the low battery limit during a mission, it will return to the launch point before landing.
