Residual Temperature Reminder
- After turning off the warmer (either manually or automatically), the red light will flash for a period. This indicates that the heating plate is still hot and caution should be exercised to prevent accidental scalding. The red light will stop flashing once the surface temperature drops below 97β (36β).

Power Off
- To manually turn off the warmer, touch the Power Button until all indicator lights are off.
Mug Compatibility
For optimal performance, it is crucial to use the correct type of mug:
- Recommended: Thin-walled, flat-bottomed, or slightly concave-bottomed mugs. Materials such as tableware, stainless steel, and glass cups are suitable.
- Not Recommended: Vacuum-sealed cups or insulated cups. These types of mugs are designed to retain heat and will not allow the warmer to effectively transfer heat to the beverage. Deep concave bottoms may also reduce heating efficiency.
