2.2 Charging the Transmitter
The Paladin EV transmitter has a built-in 1S (3.7V) 4300mAh battery. It supports two charging methods:
- USB Charging: Connect the included USB cable to the transmitter's charging interface and a 5V/2A USB power adapter. Charging time is approximately 6 hours.
- Wireless Charging: Place the transmitter on a compatible wireless charging pad. Charging time is approximately 7 hours with a 5V/2A wireless charger.
A low voltage warning will activate when the battery drops below 3.65V. Ensure the transmitter is fully charged before extended use.
2.3 Binding the Receiver
To establish communication between the transmitter and your model, the receiver must be bound to the transmitter. Refer to the included Quick Operation Guide for specific binding instructions for your receiver model. Generally, this involves:
- Powering on the receiver in binding mode (often by holding a bind button while powering on).
- Activating the binding function on the transmitter via its menu.
- Confirming successful binding, usually indicated by a solid LED on the receiver.
3. Operating Instructions
3.1 Powering On/Off
To power on the transmitter, press and hold the power button located at the bottom center until the screen illuminates. To power off, press and hold the power button again until the shutdown sequence completes.
3.2 Navigating the Touch Screen Interface
The Paladin EV features a 3.5-inch HVGA TFT touch screen (320*480 resolution) with a graphical user interface (UI). The new Flysky OS provides comprehensive functions accessible through touch input.
