Instructions:
1. Connect the radio—-ATU antenna tuner—-antenna
2. For the first use, please set the output power of the radio or power amplifier between 20-30W, warning that high-power tuning can easily damage the antenna tuner
3. Set the radio mode, use FM mode
4. Choose the antenna band to use, use 20-30W power in FM mode, press the radio PTT, watch the ATU antenna tuner PWR and SWR
5. ATU button TUNE use: short press (less than 1 second) ATU button, it is in reset state, long press (more than 1 second) ATU button is in tuning state
6. If the SWR display of the ATU antenna tuner in the transmitting state is greater than 2.0, it means that the antenna is detuned. You need to use the 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 is detuned. Seriously, it is not recommended to use a power above 30W, and the transmit 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 to transmit.
