Connect the radio-ATU antenna tuner-antenna2. When using for the first time, please set the output power of the radio or power amplifier between 20-30W, warning that high-power tuning may easily damage the antenna tuner.3. Set the radio mode, use FM mode4. Select the antenna frequency band to be used, use 20-30W power in FM mode, press the radio PPT, observe the ATU antenna tuner PWR and SWR5. The use of ATU button TUNE: Short press (less than 1 second) ATU button, it is in reset state, long press (more than 1 second) ATU button is in adjustment state6. If the SWR display of the ATU antenna tuner is greater than 2.0 in the transmission state, it means that the antenna has been detuned. You need to use an antenna tuner. Press and hold the ATU button TUNE to tune and observe the SWR value. If the SWR is greater than 3.0 after tuning, the antenna will be detuned. Seriously, it is not recommended to use a power above 30W, and the transmission power should be controlled below 30W; if the tuning is completed, the SWR display is less than 2.0, and the maximum power of 100W can be used for transmissionPackage List：1 x Automatic Antenna Tuner1 x Manual
