6 min read · English documentationThe front is the area most frequently accessed and monitored by the operator. It contains the main screen, sticks, and most frequently used buttons.
The main numbered items shown in the diagram are described below:
| No. | Component | Purpose | Precautions | Typical Use |
|---|---|---|---|---|
| 1 | Antenna | RF transmission and reception for video and data links; affects link quality and communication range | Avoid obstruction, bending, and impact; install in the correct orientation and tighten securely | Check the antenna before operation and maintain a suitable orientation during flight or tasks |
| 2 | Strap attachment | Secures a wrist strap or shoulder strap to prevent the controller from being dropped | Before use, confirm that the attachment is locked and the strap is not aged or cracked | Prevents drops during handheld outdoor or mobile operation |
| 3 | Four-way stick (left) | Typically mapped to vertical and yaw channels, subject to system configuration | Operate smoothly and avoid abrupt full deflection; confirm channel mapping and safety logic before a task | Basic altitude and heading control |
| 4 | Five-way stick (left) | Supports multi-directional and press input for menus or shortcuts | Do not confuse it with the four-way stick; functions depend on firmware or application settings | Menu selection, confirmation, and shortcuts |
| 5-6, 8 | Custom switches L1/L2/L3 (left) | Can be mapped to flight modes, gimbal, camera, or other shortcuts | Before power-on, confirm that their positions match the safety requirements; avoid accidental operation | Mode switching, one-touch functions, and custom shortcuts |
| 7 | Power button | Powers the controller on/off and wakes the screen | Follow the standard shutdown procedure and avoid forcing a shutdown by holding the button; before power-on, confirm that three-position switches are in safe positions | Routine power-on/off and wake from sleep |
| 9 | Stand | Holds the remote controller upright for hands-free placement | Place it on a level surface to prevent tipping and screen impact | Bench setup, training demonstrations, and temporary placement |
| 10 | Decorative opening | Part of the enclosure's industrial and structural design | Do not insert foreign objects; keep it ventilated and clean | — |
| 11 | Microphone (MIC) | Voice input, calls, or ambient-audio capture | Observe privacy and confidentiality requirements; some firmware can disable the microphone | Voice commands, calls, and recording where supported |
| 12 | Power indicator | Indicates power, charging, battery level, and related status | Interpret the indicator together with the battery-safety and charging guidance; stop use if an abnormality occurs | Confirms power/charging state and provides low-battery alerts |
| 13 | Front-panel status indicator group | Includes video-link, terminal, RSSI, battery-level, and other indicators for link quality and battery status | Indicator meanings can differ by firmware or system. Refer to the status-indicator documentation; pause the task and investigate if an indicator remains red or flashes rapidly | Shows whether the video link and terminal are online, signal strength, and approximate battery range. Four, three, two, or one illuminated bars indicate progressively lower charge; a flashing red final bar with a buzzer indicates critically low charge |
| 14-15, 17 | Custom switches R1/R2/R3 (right) | Symmetrical to the left-side switches and can be mapped to other functions | As on the left side, observe safe switch positions and prevent accidental operation | Right-thumb shortcuts |
| 16 | Return-to-home button | Triggers return-to-home or another preset emergency action defined by the upper-level application | Use only after confirming that it is safe and you understand the configured behavior | One-touch return-to-home or emergency action |
| 18-19 | Five-way stick (right), four-way stick (right) | Typically mapped to forward/backward and left/right translation channels | Coordinate with the left stick and operate smoothly | Horizontal movement and fine heading adjustment |
| 20 | Upper housing | Structural enclosure supporting the screen and front controls | Avoid heavy pressure and impact; send the unit for service if damaged or exposed to water | Protection and enclosure |
| 21 | Screen | Main display for video, maps, status, settings, and other functions | Avoid scratches and prolonged direct sunlight; refer to troubleshooting guidance if touch calibration is inaccurate | Primary monitoring and touch-control interface |
The side and rear areas contain interfaces, strap attachment points, cooling structures, the expansion bay, and related components.
The main numbered items shown in the diagram are described below:
| No. | Component | Purpose | Precautions | Typical Use |
|---|---|---|---|---|
| 22, 35 | Three-position toggle switches (right/left) | Multi-position switches commonly linked to safety or mode logic | Before power-on and each task, confirm that their positions meet the three-position-switch safety requirements; do not change them when their function is unknown | Safety enable, flight mode, and operation mode, subject to system definitions |
| 23, 34 | Three-position rocker switches (right/left) | Multi-position rocker switches mapped by the system or application | Understand how they interact with the toggle switches and avoid accidental mode changes | Auxiliary channels, gain, and on/off controls |
| 24, 33 | Dials (right/left) | Rotary controls commonly used for gimbal pitch, zoom, or fine parameter adjustment | Apply moderate force and avoid contacting nearby controls; actual functions depend on the application | Gimbal control, zoom, and parameter adjustment |
| 25, 32 | Rear buttons (right/left) | Rear controls operated by the index or middle finger and assignable to shortcuts | Avoid accidental presses while holding the controller; mapping depends on the system or application | Photo capture, video recording, and custom shortcuts |
| 26 | Right palm rest | Supports the right palm for stable, comfortable holding | Keep it clean and free of oil that could reduce grip | Extended handheld operation |
| 27 | Speaker | Outputs system prompts, alarms, media, and call audio | Reduce the volume in quiet environments and do not block the speaker opening | Prompts, voice feedback, and audio playback |
| 28 | Cooling fins | Assist heat dissipation and reduce temperature under high load | Do not cover or obstruct them; keep the ventilation openings free of foreign matter | High-load operation and hot environments |
| 29 | Stick assembly | Mechanical assembly for the left and right sticks | Protect from impact and liquid ingress; refer to troubleshooting guidance if abnormal | Primary control interface |
| 30 | Expansion-bay cover | Covers and protects the internal video-transmission or expansion module | Do not open or install/remove internal modules while powered; replace modules according to the supplied maintenance instructions | Installation and maintenance of video-transmission or expansion modules |
| 31 | Bay-cover release | Locks or releases the expansion-bay cover | Before opening, confirm that the unit is powered off or follow the delivery instructions | Maintenance and expansion-module replacement |
| 36 | Metal handle | Used to carry or suspend the controller | Load capacity is limited; do not hang heavy objects and prevent impacts during transport | Carrying and short-distance transport |
| 37 | Lower housing | Structural enclosure paired with the upper housing | Avoid heavy pressure and impact; send the unit for service if damaged or exposed to water | Protection and structure |
| 38, 39 | Interface dust covers (small/large) | Silicone covers protecting unused interfaces from dust | Remove the appropriate cover before connecting a cable and replace it afterward to reduce dust ingress | Interface protection and extended connector life |
Button and Channel Configuration (Remote Control Assistant)
Open the Remote Control Assistant icon on the desktop to access its home page.
When Remote Control Assistant opens, parameter loading is shown at the top. Use the application after loading is complete.
Each column typically corresponds to a channel (CH1, CH2, CH3…), with common value ranges such as 1100-1900.
The slider position indicates the current input value, and the upper and lower endpoints correspond to full travel.
