Note:
1. Insufficient adjustment may occur within 5W. So don't try to go below 5W.
2. It is recommended that the maximum power should not exceed 30 watts during tuning. (it can be set to 100 watts after tuning, and work at this power, otherwise it is easy to burn)
3. You need to use 9‑12V to start the ATU‑100. If you use a power bank or computer USB port to output power, you cannot start the ATU‑100 because their voltage is too low.
