Package Contents
Upon opening your package, you should find the following items:
- 1 x INJORA T4DCM Receiver
- Adapter wires for connection

Setup Instructions
1. Physical Installation
Due to its mini size, the T4DCM receiver is ideal for micro scale RC cars. Choose a secure location within your RC vehicle to mount the receiver, ensuring it is protected from vibrations and moisture. Ensure the antenna is positioned for optimal signal reception, away from large metal objects or carbon fiber components.

2. Wiring Connections
Connect the receiver to your Electronic Speed Controller (ESC) and other components (e.g., servos) using the provided adapter wires. The receiver features clearly labeled channels (CH1, CH2, CH3, CH4) and power (+/-) ports. Ensure correct polarity when connecting power.


3. Binding with Transmitter
The T4DCM receiver must be bound to a compatible INJORA transmitter (T6DC, T6DCG, or T6M) to establish communication. Follow these general steps for binding:
- Ensure your transmitter is turned off.
- Connect a bind plug (not included, typically comes with the transmitter or ESC) to the 'BIND' port on the T4DCM receiver.
- Power on the RC vehicle (which powers the receiver). The receiver's LED should start flashing, indicating it's in binding mode.
- While holding the bind button on your INJORA transmitter, turn on the transmitter.
- The LED on the receiver should turn solid, indicating a successful bind.
- Release the bind button on the transmitter, then turn off both the transmitter and the RC vehicle.
- Remove the bind plug from the receiver.
- Turn on the transmitter first, then the RC vehicle. Test the controls to ensure proper functionality.
Refer to your specific INJORA transmitter's manual for detailed binding instructions, as the exact procedure may vary slightly.
Operating Instructions
Once successfully bound to your transmitter, the T4DCM receiver will translate the signals from your transmitter into commands for your RC vehicle's components. Always power on your transmitter before powering on your RC vehicle, and power off your RC vehicle before powering off your transmitter, to prevent loss of control.
- Power On Sequence: Transmitter ON first, then RC vehicle ON.
- Power Off Sequence: RC vehicle OFF first, then Transmitter OFF.
- Range Check: Before operating your RC vehicle at a distance, perform a range check in a safe area to ensure reliable signal reception.
Maintenance
Proper maintenance will extend the lifespan of your T4DCM receiver:
- Keep Dry: Avoid exposing the receiver to moisture or water. While compact, it is not waterproof unless explicitly stated or housed in a waterproof enclosure.
- Cleanliness: Periodically clean the receiver and its connections with a soft, dry brush to remove dust and debris.
- Secure Connections: Ensure all wires are securely plugged into the receiver and other components. Loose connections can lead to intermittent signal loss.
- Antenna Care: Do not cut, bend sharply, or damage the antenna wire. Ensure it is routed away from moving parts and metal.
- Temperature: Operate the receiver within reasonable temperature ranges. Extreme heat or cold can affect performance.
Troubleshooting
If you encounter issues with your T4DCM receiver, consider the following common solutions:
| Problem | Possible Cause / Solution |
|---|---|
| Receiver LED not lighting up |
|
| Receiver not binding |
|
| Loss of control / Glitching |
|
| Servos/ESC not responding |

User Tips
While no specific user reviews or Q&A were provided, general tips for RC enthusiasts using compact receivers include:
- Antenna Placement: For micro vehicles, careful antenna routing is crucial. Try to keep the antenna wire as straight as possible and away from carbon fiber or metal parts for best range.
- Space Management: Utilize the compact size of the T4DCM to your advantage in tight chassis. Consider using double-sided foam tape for secure mounting and vibration dampening.
- Power Source: Ensure your power source (ESC's BEC or separate battery) provides stable voltage within the 3-10V range to the receiver.
