6.5 Low Battery Capacity Warning Function

The low battery capacity warning alerts users when the battery is close to depletion during flight. When it appears,

users should promptly fly back and land to avoid accidental damage. The PHANTOM 2 has two levels of low battery

capacity warning. The first appears when the battery has less than 30% power and the second appears when it has

less than 15% power.

（1） When battery power drops below 30% and LED indicator will blink red slowly.

（2） At lower than 15% the LED indicator will blink red rapidly, the PHANTOM 2 will also begin to descend and

land automatically. After it has landed, keep the throttle stick at its lowest point or execute CSC.

（3） There is a hidden third low battery threshold in addition to the 1st and 2nd level warnings. This uses 10.65V

as its threshold. Both this voltage threshold and the 2nd Level Low Battery Warning will trigger auto-landing.

Altitude can be maintained if necessary by pushing up on the throttle stick.

（1） Remember to fly your PHANTOM 2 back as soon as you see a low battery capacity warning.

（2） Keeping the battery contact needles and pads clean is very important. Any dirt and dust may

cause a communication failure.

6.6 Flight Limits Function

All UAV (unmanned aerial vehicle) operators should abide by all regulations from such organizations at ICAO

(International Civil Aviation Organization) and per country airspace regulations. For safety reasons, the flight limits

function is enabled by default to help users use this product safely and legally. The flight limits function includes

height, distance limits.

In Ready to Fly status, height, distance limits works together to restrict the flight. In Ready to Fly (non-GPS) status,

only height limit works and the flying height restricted to be not over 120m.

(1) The default parameters in the Assistant is compliant within the definitions of class G ruled by

ICAO. (Refer to Airspace Classification to get more details). As each country has its own rules,

make sure to configure the parameters to comply with these rules too, before using the

PHANTOM 2.

(2) Users in Mainland China can refer to 民用航空空域使用办法.

Max Height & Radius Limits

The Max Height & Radius restricts the flying height and distance. Configuration can be done in the PHANTOM 2

Assistant. Once complete, your aircraft will fly in a restricted cylinder.
