3.Anti-Ground radar （https://support.jiyiuav.com/docs/sging/sging-1c8hcvnb8ipbl ）
note:
When installing the radar, it should be noted that there is no obstruction in the range of 60 degrees below (as shown in the figure), and try to stay away from water mist.
About the setting of radar sensitivity
Low sensitivity: suitable for high-stalk crops (such as sorghum, corn, etc.), gentle, limiting the rate of decline.It can prevent the rising and shaking caused by the lodging of the high pole and the uneven high pole.
Medium sensitivity: suitable for most scenes and non-high-stem crops (such as rice, wheat, soybeans, etc.). Moderate speed and moderate response.
High sensitivity: suitable for demonstration effects, and some non-working entertainment occasions, sensitive, fast rise, fast fall.
4.Obstacle avoidance radar （https://support.jiyiuav.com/docs/skning/skning-1c8jtpfthji51 ）
note:
The radar is installed in front of the UAV and tilted upward by 10~15 degrees. It should be noted that there is no obstruction within 15 degrees in the front (as shown in the picture), and try to stay away from the water mist.
5.KBOX-4
Function:
1.Can provide network signal to RTK (for domestic use only)
2.Job records can be cached in the background of the computer
Port connection:
1. KBOX-4: K++ flight control EXT2 port
2. 4G ANT connects to the standard 4G antenna
3. SIM1, SIM2: local SIM mobile phone card (must have data traffic)
6.Remote control and receiver
Note:
When the remote control is turned on, and the green light on the receiver is off, you need to link the frequency.
Linking operation: firstly short-circuit the MODE KEY and GND port to supply power to the receiver, the green light starts to flash, turn on the remote control, and the green light is always on, it means the link is successful.
