Notice:
1. Insufficient adjustments may occur within 5W, so do not lower it than 5W. 2. It is recommended to not exceed 30W of maximum power when tuning. (You can set it to 100W and operate at this power after tuning, otherwise it may burn out.)
3. You need to use a voltage of 9‑12V to start the ATU 100. If you use a mobile power source or a computer USB interface power output, you cannot start the ATU 100 due to their low voltage.
