- The yellow setting is intended only for devices rated below 240W and is not suitable for high-power applications.
- If the LED flashes or the button does not respond, disconnect the power for 10 seconds and then reconnect it.
- Directly skipping a setting is not supported. The four modes must be selected sequentially.
