Requirements for Flight Environment
1. Never fly in bad weather conditions, such as gale (Grade 4 or higher), snow, rain and fog.
2. Fly in broad space with no tall buildings nearby, for reinforced concrete buildings will affect
compass and shield GPS signal, which finally results in unsafe flight due to poor positioning
performance or failure in positioning.
3. While flying, please keep the aircraft in sight and away from obstacles, the crowd and water
surface.
4. Never fly at the region with high-tension wire, transformer and communication base station,
launching tower, satellite antenna, high iron stand and steel bar for fear of interfering signal.
While flying, please keep the aircraft in broad space and in sight and control flying speed.
Never fly in bad weather conditions, such as gale (Grade 4 or higher), snow, rain, lightening and
fog.
While flying, please keep away from tall buildings, electrical tower, signal tower, high iron stand
and steel bar, tall trees, the crowd and water surface.
If the aircraft flies above 3,500 m altitude, the properties may be affected by decline of
aircraft battery and dynamical system properties due to environmental factors so be careful with it.
GPS positioning of aircraft is not available in arctic and antarctic circle but the user can fly aircraft
with visual positioning system.

Preparation
Downloading APP J.ME Fly
J.ME Fly is the supporting intelligent APP developed for intelligent aircraft J.ME and the user can
realize various functions of aircraft with J.ME Fly, such as intelligent flight control, shooting and
recording, photo and video editing and social sharing; it can bring the user with unprecedented
perfect intelligent flying experience.
Before using this product, you need to download and install J.ME
Fly App by scanning the QR code on the right and enter
downloading page or explore J.ME Fly App at App Store or
Android market.

Aircraft preparation
Aircraft startup and shutdown
Short press power switch and long press it for 3s and
the aircraft will start up or shut down.
Connect aircraft and J.ME Fly
If the aircraft is started up, connect corresponding
Wi-Fi signal with mobile equipment and the default
name of Wi-Fi is JME-XXXXX (you can check it on
packing box) and the default password is jme12345.
After the mobile phone is connected to Wi-Fi, please
open J.ME Fly and check connection status.
Normal connection status Abnormal connection status
If it displays abnormal connection, please reconfirm Wi-Fi connection status.
Compass Calibration
Calibrate the compass each time after starting up J.ME power supply; otherwise, the system
may not be able to work normally and it may affect flight safety; the compass can be disturbed by
other electronic equipment easily, resulting in abnormal data, affecting flight and even causing
flight accident. The frequent calibration can keep the compass at the best working conditions and
the user can prepare flight after calibrating compass.
Tips:
Calibrate compass by keeping it 1 m above ground;
Never calibrate at high magnetic field, such as magnetic mineral, parking lot and
underground reinforced concrete buildings;
Please avoid taking any magnetic article, such as key or mobile phone while calibrating;
Calibrate by keeping off large block of metal;
If the yellow lamp of aircraft indicator still flickers after calibration, check APP display and
calibrate compass again.
Calibrate the compass through 3 circles.

Calibration Steps
Please select an open site and calibrate based on steps below.
1. Enter J.ME FLY setting interface, select the “enter flying setting page” at top right corner
and slide to “compass calibration” interface to calibrate.
2. Click “Start Calibration”; if the red aircraft status indicator becomes normally on, the compass
calibration procedure starts and then operate following coordinate in the diagram below and
following steps.
Rotate the aircraft body by 360 along Axis Z, and the yellow indicator lamp will turn on after
completion;
Rotate the aircraft body by 360 along Axis Y, and the green indicator lamp will turn on after
completion;
Rotate the aircraft body by 360 along Axis X, the red indicator lamp at head will turn on and
the green indicator lamp at tail will flicker after completion.
Re-calibration is needed if:
The compass data are abnormal and the yellow indicator lamp flickers;
The flight site is far away from last one calibrated by compass;
The structure of aircraft is changed;
During flying, the aircraft drifts seriously or is not able to fly in a straight line; or
Battery is changed.
For more about compass calibration, please check relevant teaching videos.
