Operation Controls & LED Indication
Channel / Band / Power Control
| Control | Description |
|---|---|
| Channel control buttons | Set BAND: Long press for 2 seconds to switch channel groups – Green light flashes once (Channel A group) / flashes twice (Channel B group). Set CH1~CH8: Short press once → blue light flash 1x (CH1); short press 2x → blue light flash 2x (CH2) … and so on up to CH8. |
| Power control button | Long press >2s: red light ON (PIT mode). Short press 1x: red flash 1 → 25mW Short press 2x: red flash 2 → 200mW Short press 3x: red flash 3 → 2W Short press 4x: red flash 4 → 4.5W |
LED Indicator Summary
Blue LED Channel indicator: flash 1 = CH1, flash 2 = CH2, … flash 8 = CH8
Green LED Frequency group: flash 1 = Group A, flash 2 = Group B
Red LED Power: steady = PIT; flash 1 = 25mW; flash 2 = 200mW; flash 3 = 2W; flash 4 = 4.5W
⚠️ Precautions for Use
- ✅ Please confirm the RF output antenna is properly installed before powering on — otherwise the module may be burned out.
- ✅ Before connecting power, ensure correct voltage range and polarity (+/-) to avoid component damage.
- ✅ Try to use antennas with good VSWR and gain to achieve longer transmission distances.
- ✅ During operation, the surface may become very hot. Do not touch directly to avoid burns.
