4. Setup
4.1 Transmitter Battery Installation
The C7 MINI transmitter can be powered by 4 AAA batteries or a 2S lithium battery. The battery compartment is located on the back of the transmitter.
- Open the battery compartment cover on the back of the transmitter.
- Insert 4 AAA batteries, ensuring correct polarity, or connect a 2S lithium battery to the balance port.
- Close the battery compartment cover securely.
4.2 Receiver Binding (Frequency Matching)
To establish communication between the transmitter and receiver, you must perform frequency matching (binding).
- Ensure the receiver is powered on.
- Press the touch button on the receiver.
- Turn on the power switch of the remote control (transmitter).
- The frequency matching should be successful, indicated by a solid light on the receiver.
5. Operating Instructions
5.1 Basic Operation
- Power On/Off: Use the power switch on the front of the transmitter.
- Rocker Controls: Use the left and right rockers to control your model's movement.
- Trim Adjustments: Use the trim buttons (Throttle, Elevator, Rudder, Aileron) for fine-tuning control surfaces.
- Switches (SW-A, SW-B, SW-C, SW-D): Assign these switches to various functions on your model, such as gear, flaps, or flight modes.
5.2 Menu Navigation
Use the Menu key, Exit key, Up button, and Down button to navigate through the transmitter's display menus for system and model settings.
5.3 Key Lock Function
The Key Lock function prevents accidental input. When activated, the keys are invalid to prevent misoperation.
5.4 Travel Setting
The travel setting limits the range of movement for control surfaces, ensuring they operate within your desired parameters.
5.5 Speed Lock (for Car/Boat models)
In car or boat mode, the speed lock function can be engaged. When turned on, models using a differential structure will maintain the same speed without changing.
5.6 Simulation Training
The C7 MINI transmitter supports simulation training. You can connect the remote controller to a computer via the audio interface for simulation training.
6. Maintenance
- Cleaning: Use a soft, dry cloth to clean the transmitter and receiver. Avoid using solvents or abrasive cleaners.
- Storage: Store the radio system in a cool, dry place away from direct sunlight and extreme temperatures. Remove batteries if storing for extended periods.
- Battery Care: Always use fresh batteries or fully charged LiPo batteries. Do not mix old and new batteries.
- Antenna Care: Ensure the receiver's external antennas are not bent or damaged.
7. Troubleshooting
7.1 No Signal / Loss of Control
- Check Batteries: Ensure both transmitter and receiver have sufficient power. Replace or recharge batteries if necessary.
- Re-bind Receiver: Perform the frequency matching procedure again (Section 4.2).
- Check Connections: Verify all wires between the receiver and model components are securely connected.
- Range: Ensure you are within the specified control range (>800m for transmitter, >1000m for receiver). Obstacles can reduce range.
- Interference: Operate in an area free from strong radio interference.
7.2 Runaway Protection
The system supports runaway protection. If the receiver cannot receive the transmitter signal (e.g., transmitter is turned off, or distance exceeds range), the system will return to a pre-set out-of-control protection value to prevent damage to the model.
7.3 Display Issues
- Backlit Display: The C7 MINI features a backlit display, allowing normal operation even in direct sunlight. If the display is unreadable, check battery levels.
8. User Tips
- Control Distance: The system offers a control distance of over 800 meters for the transmitter and over 1000 meters for the receiver. Always maintain line of sight with your model and be aware of environmental factors that might affect signal range.
- Compatibility: The C7 MINI is compatible with a wide range of MicroZone receivers, including MC8RE-V2, MC9002, MC6RE-V2, MC7RB-V2, MC3RB, MC4RB, MC6RE, MC7RB, MC8RE, E6R-E, and M-BUS.
9. Warranty and Support
For warranty claims or technical support, please contact your retailer or the official MicroZone support channels. Keep your proof of purchase for any warranty-related inquiries. This product is designed for hobby use and proper operation is essential for safety and longevity.
10. Safety Information
- Always operate your RC model in a safe and responsible manner.
- Ensure you have sufficient space and are away from people, animals, and property.
- Never operate your model near power lines, roads, or airports.
- Always turn on the transmitter first, then the receiver. When finished, turn off the receiver first, then the transmitter.
- Regularly inspect your equipment for any signs of damage or wear.
- Do not modify the transmitter or receiver, as this may void your warranty and compromise safety.
- Keep batteries away from heat sources and do not short-circuit them.
