II. Operation Guide
1. Switch Location
The hidden button switch is located inside the circular hole on the DC head product.
2. Gear Switching
A light press cycles through the gears in the following order:
- Gear 1 (Purple Light): 330W Mode | Negative pole
- Gear 2 (Green Light): 300W Mode | Negative pole
- Gear 3 (Blue Light): 240W Mode | Negative pole

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
Q1: The button does not respond. What should I do?
Check the power connection and make sure the button surface is clean and unobstructed. If the issue persists, disconnect power for 10 seconds and restart.
Q2: Can I skip gears directly?
No. Skipping a gear is not supported; you must cycle through sequentially from Gear 1 to Gear 4.
Q3: What does a flashing LED light mean?
A flashing light typically indicates a power mismatch or an unstable connection. Ensure the connected device's power requirement matches the selected gear, then reconnect.
Q4: Does the converter remember my last gear setting?
Yes. The device has a memory function and will automatically resume the last selected gear when powered on again.

This converter is designed for Lenovo laptops with a Square Port connector, supporting power inputs of 330W and below. Please verify your laptop's power specification before use.
