Notes: if power is off during temperature setting, the new temperature will not be
saved.
• If the “*” key is pressed less than 1 second, the set temperature will be displayed for 2
seconds. Display will be automatically switched back to pre-heat plate temperature.
• After the ‘*’ is pressed, power supply to heating elements will be out off.

(b). Temperature Setting during Heating
If it is necessary to change plate temperature quickly while power supply to heat element is still
maintained, the following procedure can be followed:
Raising the temperature:
Press the ‘▲’ key directly without pressing the “*” key. Doing so will raise the set
temperature 1℃. If the ‘▲’ key is released, it will not respond to new input within 2
seconds. Press the ‘▲’ key again after two seconds will raise the temperature another 1℃.
If the ‘▲’key is pressed for least 1 second, the set temperature will be
incremented automatically until the‘▲’key is released.
Lowering the temperature:
Similar to above, the ‘▼’ key is used instead.
