1. Safety Precautions

1. Do not connect or disconnect USB devices during flight. Doing so can cause control latency, stuttering, device disconnection, or recognition errors.

2. The XT-30 input range is 7.4-28V. The device can also be powered with 5V through the Type-C port. Type-C power does not supply the RF module and powers the device on directly, so the power button is disabled.

3. Do not supply power through the TYPE-C and XT-30 ports simultaneously; this may cause reverse current flow.

4. Reversing the XT-30 polarity generally will not damage this device, but it may damage the RF module.

5. XT-30 input voltage is supplied directly to the RF module. Reversed polarity can damage the RF module. Also verify the RF module input range; for example, some modules support only 6-16.8V and may be damaged by higher voltage.

6. When using an externally mounted RF module with an independent power supply, pay close attention to the power wiring. Unless this device and the RF module share the same power source, different supply voltages may backfeed each other and damage the RF module or this device. For an independently powered RF module, connect only GND and the signal wire, and remove the positive power pin.

7. For aircraft with a flight controller or with signals relayed through a radio transmitter, configure leveling, travel range, and similar parameters on the flight controller or radio transmitter. Use this device only for button binding and channel mapping.

8. Before first use, configure the channels and bind the buttons for your operating preferences. Configurations are not saved automatically; save them manually in Configuration Management.
