2. Placement: Place the warmer on a clean, dry, flat, and stable surface. Ensure there are no obstructions underneath the unit.
3. Power Connection: Plug the power adapter into a standard 110V electrical outlet.
4. Initial Cleaning: Before first use, wipe the heating plate with a lightly damp cloth. Ensure the unit is completely dry before plugging it in.

4. Operating Instructions

Powering On/Off:

• To turn on, place a cup weighing at least 10.4 oz (295 g) on the heating plate, then press the power button.
• To turn off, press the power button again.

Temperature Adjustment:

• Use the up (▲) and down (▼) arrow buttons on the digital display to adjust the desired heating plate temperature.
• Temperature can be set from 77°F–194°F (25°C–90°C) in 1° increments.
• The warmer will maintain a liquid temperature of up to 131°F (55°C) depending on the cup type and initial liquid temperature.

Digital Display:

• The LCD screen displays the current temperature of the heating plate.
• The memory function will recall your last temperature setting when the unit is powered on.

Pressure Sensor Technology:

• The warmer is equipped with a pressure sensor that detects the presence of a cup. It will only begin heating if a cup of sufficient weight is placed on the plate and the power is on.
• This feature prevents accidental heating when no cup is present.
• The pressure sensor can be turned off if not desired, but this will disable the automatic shut-off feature.

Automatic Shut-off:

• For safety, the warmer automatically shuts off after 8 hours of continuous activity.
• If the pressure sensor is disabled, the automatic shut-off function will not operate, and the warmer will continue to work until manually turned off.

Recommended Cup Types:

• For best results, use flat-bottomed, heat-safe cups made of stainless steel, glass, or ceramic.
• Cups with thick or concave bottoms may not transfer heat as efficiently.

Efficiency Notes:

• The time it takes to warm a beverage depends on the initial temperature of the liquid and the ambient room temperature.
• A lid on your cup can help retain heat and warm beverages faster.

5. Maintenance

Cleaning:

• Always unplug the warmer and allow it to cool completely before cleaning.
• Wipe the heating plate and exterior with a soft, lightly damp cloth.

• Never immerse the warmer in water or any other liquid.

6. Troubleshooting

Common Issues and Solutions:

• Warmer does not turn on:
  • Ensure the power cord is securely plugged into a working outlet.
  • Verify that a cup weighing at least 10.4 oz (295 g) is placed on the heating plate.
  • Check that the warmer is on a flat surface and no objects are interfering with the pressure sensor underneath.
• Beverage is not warm enough:
  • Confirm the temperature setting is appropriate for your desired warmth.
  • Use a flat-bottomed, heat-safe cup for optimal heat transfer.
  • Consider using a lid on your cup to retain heat more effectively.
  • Note that the warmer maintains temperature, it does not rapidly heat cold liquids to boiling.
• Automatic shut-off not working:
  • The 8-hour auto shut-off function is dependent on the pressure sensor. If the pressure sensor is manually turned off, the auto shut-off will not activate.
