# 1.3 Connections and us e (1) Please assemble the antenna of the Ground end first. (2) For connections and use pl ease refer to the diagram below.

Notes : (1) You can configure the Flight control system using the Assistant software on a PC or iOS mobile Device wirelessly over the link of the 2.4G Bluetooth Datalink, however you cannot upgrade the firmware of the Flight control system using this communication r oute. (2) W hen connecting a BTU module or a LED Bluetooth unit to the Flight control system to configure in the Assistant on mobile devices, as well as connecting a BTU module to the Ground end to use the iPad Ground station , the two Bluetooth communication li nks will not interfere with each other. (3) I f the Air end is changed to connect to a new Main controller, you should power cycle the Ground end. (4) M ake sure the LED indicator of BTU module is green after power on
, for specific usage details please refer to the BTU Manual. (5) For u sage of the PC Ground Station please refer to the latest Ground Station User Manual. I mportant : (1) If there are obstacle s between the ground and air end s then the radio signal of the 2.4G Bluetooth Datalink will be weak; please make sure t he antenna s are always visibl y unobstructed during the flight. Human body, trees, buildings or hills will disconnect the link between the A ir end and the G round end. (2) Make sure the antenna of the A ir end is pointing down, and the antenna of the G round end i s pointing upwards ; it ’ s better to put the G round end at a high place to get further transmission distance. (3) W hen using the ACE ONE Flight control system with the 2.4G Bluetooth Datalink, the Ground Station will connect to the Main controller 15s after powe r on.© 201 3

Refer to all help text in the App.



# 2 .3 Using Tips
1. Customized Route Template
I n Waypoints mode, users can set a route and click to save it as a template. U sers ca n view all the customized route templates in the template menu, slip from right to left on a template and you can choose to detele it.

2. Capturing waypoints I n Waypoints mode, click to capture the aircraft attitude (including longitude, latitude, height a nd nose pointing direction ) properties to build a new waypoint during flight. T his function is always available when the
UAV is hovering or flying.

3. GPS SNR Display iPad Ground S tation ha s added “SNR Health” and “SNR Fluctuation” index monitors for GPS sig nals. Pilots will be able to monitor GPS signal quality, ensuring they have strong and stable signals for better flight performance. By referring to these two values, pilots will be empowered to f ind the best locations for take off and flight, while also de tecting areas that might interfere with GPS signals.
Click . The SNR interface provides you with “SNR Health” and “SNR Fluctuation” index monitors whose values change according to aircraft maneuvers and environmental interference.

 The “SNR Health Index” shows the GPS signal strength captured by the GPS receiver. A larger number indicates a stronger GPS signal. We highly recommend pilots only take off when the SNR health value is greater than 36.© 201 3

 The “SNR Fluctuation Index” shows the overall stability of the craft’s current GPS signal. A smaller number means that the signals will fluctuate less and provide a more stable GPS signal overall.



# 2 .4 Flight Limit of Special Area s All UAV operators should abide by all regulations from such organizations at ICA O (International Civil Aviation Organization) and per country airspace regulations. For safety reasons, key areas have been restricted, such as: a) W ithin the radius of 8Km from the airport. U sers will not be able to build waypoints or Home points in designa ted special areas and the waypoint routines go through these special areas are invalid
, and the UAV will fail to cruise to those areas. All the special areas have been restricted are specified on the DJI official website and please refer to Special Areas List ( http://www.dji.com/fly
