Transmitter Details





Setup
1. Transmitter Battery Installation
The T3PM transmitter requires 8 AA batteries (not included) for operation. Ensure batteries are inserted with correct polarity.
- Open the battery compartment cover on the back of the transmitter (refer to Figure 3).
- Insert 8 AA batteries, paying close attention to the positive (+) and negative (-) markings inside the compartment.
- Close the battery compartment cover securely.

Note: The display will show the current battery voltage. A reading of 9.4V indicates fully charged batteries.
2. Receiver and Servo Connection
Connect the receiver and servo to your model's electronic components. Refer to your model's specific instructions for mounting and wiring.
- Connect the servo to the appropriate channel on the receiver (e.g., Channel 1 for steering).
- Connect the Electronic Speed Controller (ESC) to the receiver's throttle channel (e.g., Channel 2).
- Ensure all connections are secure and correctly oriented.
3. Binding the Transmitter and Receiver
The transmitter and receiver must be "bound" to each other to establish a secure communication link. Refer to the detailed binding procedure in the full manual for your specific receiver model (e.g., R603FS).
Operating Instructions
1. Powering On
- Turn on the transmitter first.
- Then, turn on the receiver/model power switch.
2. Basic Controls
- Steering Wheel: Rotate left or right to control the steering of your model.
- Throttle Trigger: Pull to accelerate forward, push to brake or reverse.
- Display and Buttons: Use the display and associated buttons (SEL, CH) to navigate menus and adjust settings such as trim, servo reverse, and endpoint adjustments.
3. Powering Off
- Turn off the receiver/model power switch first.
- Then, turn off the transmitter.
Important: Always turn on the transmitter before the receiver and turn off the receiver before the transmitter to prevent loss of control.
Maintenance
- Cleaning: Wipe the transmitter and receiver with a soft, dry cloth. Do not use solvents or abrasive cleaners.
- Storage: Store the system in a cool, dry place away from direct sunlight and extreme temperatures. Remove batteries from the transmitter if storing for extended periods.
- Battery Care: Use high-quality batteries. If using rechargeable batteries, follow the manufacturer's charging instructions.
- Antenna Care: Ensure the transmitter antenna is not bent or damaged. The receiver antenna should be routed correctly within your model to maximize range.
