To power on the controller, press and hold the power button until the screen illuminates. To power off, press and hold the power button again until the shutdown sequence completes.

3.2 Basic Controls and Ergonomics

The TX12 MKII features high-precision hall gimbals for smooth and accurate control. The rear case has comfortable grips, and the S1/S2 slider grips have been improved for better tactile feedback. The controller also includes a standard JR module bay for external modules.

The 128x64 monochrome LCD display provides clear information. Use the navigation buttons (SYS, RTN, PAGE>, PAGE<, TELE) to move through menus and adjust settings within the EdgeTX operating system.

3.4 Binding and Pairing (ELRS Protocol)

The TX12 MKII supports ExpressLRS (ELRS) and CC2500 RF chips. For ELRS binding, ensure your drone has a compatible ELRS receiver. The power-on pairing method is typically used: power on the drone three consecutive times. Observe the receiver light; it should flash twice continuously, indicating it's in pairing mode. Then, on the remote control, switch to ELRS 2.4G protocol (if not already) and initiate the binding process. The remote control may vibrate, and the receiver light will steady upon successful pairing.

3.5 Simulator Use

The TX12 MKII can be connected to a computer via its USB-C port for use with flight simulators. This allows for practice and skill development without risking actual models. Ensure the simulator software is configured to recognize the controller as a joystick.

4.1 Gofal Batri

Always use compatible batteries and follow manufacturer guidelines for charging and storage. Avoid overcharging or fully discharging Li-ion/Lipo batteries to prolong their lifespan. Store batteries in a cool, dry place away from direct sunlight.

4.2 Glanhau a Storio

Clean the controller regularly with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials. When not in use, store the controller in a protective case to prevent dust accumulation and physical damage. Ensure the antenna is folded or removed if applicable for compact storage.

• Methiant Rhwymo: Verify that both the controller and receiver are set to the correct protocol (e.g., ELRS). Ensure the receiver is in pairing mode (often indicated by a specific light pattern after multiple power cycles).
• Rheolaethau Anymatebol: Calibrate gimbals and switches through the EdgeTX menu. For simulator use, ensure USB drivers are updated and the simulator recognizes the controller.
• Short Range/Signal Loss: Ensure the antenna is securely attached and not obstructed. Check for local interference. Update firmware on both the radio and receiver.

5.2 Diweddariadau Firmware
