YUEOU ATU-100-0A 1.8-55MHz Mini Automatic Antenna Tuner 0.91inch OLED Display Aluminum Alloy Outcase with1800MAh Battery

PTT, observe the PWR and SWR of ATU antenna tuner. 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. If the SWR display of the ATU antenna tuner in the transmitting state is ＞2.0, it means that the antenna is detuned.6.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. In serious cases, it is not recommended to use more than 30W power, 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 transmission.
