IV. Precautions When Powering On
8. Before using, make sure that all cables are secure and reliably and all components can work properly.
9. After starting the product, check it for proper operation by observing whether the self-test indicator of
ST5/10/20NPT is continuously ON for 30s and then flicker and whether the image of the camera is
shown on the ground terminal.
10. Check the surrounding environment for to ensure there is no other 2.4GHz devices to cause
interference. If use the Futaba remote controller, the controller should be adjusted into the French
mode. Otherwise, the video transmission performance of ST5/10/20NPT may be serious affected and
also the Futaba transceiver may be in the abnormal status and accidents may be caused.
11. Remark: How to adjust the Futaba controller into French mode:
[LINKAGE MENU]→FRQUENCY→ RTN b→ [AREA]→[FRANCE]
12. Before use, check the electric quantity of the ground terminal. If the ground terminal is OFF, the
built-in radio receiver of the onboard terminal will be out-of-control.
13. Pay attention to the angle and direction of the antenna of the ground terminal during flight. In case of
poor signal or image quality, adjusting the inclination of the antenna of the ground terminal can
improve the signal or image effect.
14. The camera should be fully charged to ensure normal video output.
15. ST5/10/20NPT has the functions of two-way communication of image data and serial port data. If the
transmitted ground image is stuck or stopped for more than 10s but less than 30s, it means that the
radio channel signal is weakened or the radio channel is narrowed. In this case, the aircraft must not fly
farther away from the ground. In order to ensure the normal communication of serial data and the
safety of the aircraft, the distance between the aircraft and ground terminal should be immediately
shortened. Otherwise, the built-in radio receiver of the onboard terminal will be out-of-control.
16. 8. If required, purchase electronic devices (such as HD displays, Network cables, etc.) with good
electromagnetic shielding effects.
