II. Operation Guide
1. Switch Location
The hidden button switch is located inside the circular hole on the DC head product.

A light press cycles through the gears in the following order:

3. Operation Confirmation
After each press, the LED light color instantly displays the current gear. The device automatically runs at the set power and has a memory function, so no repeated operation is needed next time.
III. Important Notes
- Ensure the device's power matches the gear to avoid error messages from the device.
- When switching gears, press lightly and quickly. A long press may cause the switch to cycle continuously.
- The yellow gear (below 240W) is compatible with low-power devices and is not suitable for high-power use.
- If the light flashes or there is no response, disconnect power for 10 seconds and then restart.
IV. Frequently Asked Questions
If the button does not respond, check the power connection and make sure the button surface is clean and unobstructed. Skipping a gear is not supported; you must cycle through sequentially.
V. Safety
Do not disassemble the switch unless you are a qualified professional.
Take precautions against moisture when using in humid environments.
