1.As is shown in Figure 1-3 , when Seraphi is flying in or between tall buildings in the GPS Mode,
some GPS signals are likely to be lost due to the around barriers, which will cause some loss or
errors of satellite positioning data. If so, seraphi might fly to one direction abnormally . Please
switch GPS Mode to Attitude Flight Mode immediately and then you can continue to control
Seraphi as you please.

1.For the first flying, beginners are strongly suggested taking necessary trainings by professionals or doing some pre-exercises on
simulators until you can skillfully operate the aircraft or the simulator and the remote controller
2. During flying, please make sure that Seraphi is always within sight and its back light always faces its operator so that he could
determine its flight attitude and adjust its flight directions when necessary.
3. During flying, what's more, please watch the flash of back light at any time and keep alert to Low-Voltage signals. Low-Voltage Alert is
to indicate that the battery cannot provide enough power for the aircraft and you should land the aircraft to avoid or reduce crashes ASAP
4. Sensors in the heart of SeraphI are damageable, so be sure not to hit or drop the aircraft heavily. Otherwise, the inertial measuring unit
(IMU) might be destroyed. If Seraphi flies in an abnormal way after being hit or dropped Seriously, please return it to Yunyi-Flight to repair
immediately.

1.Abnormal rotation of propellers
You have executed Unlock Motors procedure, but the aircraft abnormally shakes and the propellers won't rotate. We advise you to lock
and stop the motors and then unlock . Try again until the propellers could rotate well. In case the propellers still can not rotate, have a try
to push a propeller by hand to aid its rotation. If they keep still again, please return the aircraft to Yunyi Flight to repair.
V. Possible Malfunctions and Solutions
2.Seraphi fly to one direction abnormally
Please do horizontal calibration
3 When switching to GPS flight mode, observe seraphi movement ,if it fly to one direction abnormally , switch to Attitude mode
quickly, land aircraft, and carry out Compass calibration , and then try again.
NOTE:
1.In any Drop or rollover cases or the first use or did not use it for a long time .You should carry out this step. This will ensure a stable
flight .
2.you should ensure it put on a horizontal ground,do not move seraphi during calibrating.
Please calibrate the compass in follow cases:
1.When flying on GPS Flight Mode, the aircraft can not hover stably in the air or circles around unusually, or flies aside to one
direction abnormally;
2. When performing fly-home, the aircraft cannot return to the home point.
