2.2 Smart Sensor Function and Auto Shut-Off
The SEALON SLM02 features a smart sensor that detects when a mug is placed on the heating plate. Heating will only activate when a mug is present. If the mug is removed, the heating will automatically stop.
For safety and energy efficiency, the mug warmer is equipped with an automatic shut-off function. The device will automatically turn off after 4 hours of continuous operation.

2.3 Recommended Mug Types
For optimal performance, use mugs with a thin wall and a flat or slightly concave bottom. The warmer is suitable for a variety of materials including tableware, stainless steel cups, ceramic mugs, milk boxes, and glass cups.
Not Recommended for: Thermos cups, vacuum glass, bagged drinks, or plastic cups, as these may not allow for efficient heat transfer or may be damaged by heat.

4. Troubleshooting
If you encounter any issues with your SEALON SLM02 Coffee Mug Warmer, please refer to the table below for common problems and their solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Warmer is not heating. | Not plugged in, power button not pressed, mug not on sensor, or unsuitable mug type. | Ensure the warmer is securely plugged into a working outlet. Press the power button. Place a suitable mug (thin-walled, flat bottom) firmly on the heating plate to activate the smart sensor. |
| Beverage is not warm enough. | Incorrect temperature setting, unsuitable mug type, or initial beverage temperature too low. | Select a higher temperature setting (Mid or High). Use a thin-walled, flat-bottomed mug for better heat transfer. The warmer is designed to maintain warmth, not rapidly heat cold beverages. |
| Warmer automatically turns off. | 4-hour auto shut-off activated, or mug removed from sensor. | This is a safety feature. If you wish to continue warming, simply turn the unit back on. Ensure the mug remains on the heating plate. |
