PROGRAMMING

Preprogrammed Number Pads

Oven has 10~20 preprogrammed number pads. Follow
instructions below to program heating times and power
levels for customized cooking.

1. Open oven door.

• If door is closed or RESET pad is pressed before

finishing programming sequence, oven exits 
programming mode.

2. Press and hold pad for approximately 5 seconds.

• After 5 seconds, signal sounds. Display shows

“PROGRAM” indicating program mode.

3. Press desired number pad.

• Display shows heating time, “COOK LEVEL” and

power level if other than 100 percent power.

4. Press number pads to enter desired cooking time.

• For example, to heat for 2 minutes 30 seconds, press

23, and 0 pads.

5. Press desired power level pad to change power level.

• If a power level pad is not pressed, oven defaults to

100% power.

• For example, pressing MEDIUM 50% pad sets oven to

50% power.

• Display shows current power level if other than 100%

power.

6. Press START pad to save new heating time and power

level in oven memory.
• Repeat step 3-6 to program additional pads.

7. Press RESET pad or close oven door to exit 

programming mode.

Multiple Heating Stages

Follow instructions below to program oven to perform 3
consecutive heating cycles without interruption.

1. Open oven door.

• If door is closed or RESET pad is pressed before

finishing programming sequence, oven exits
programming mode.

2. Press pad for approximately 5 seconds.

• After 5 seconds, signal sounds.

3. Press desired number pad.

• Display shows heating time and preprogrammed

number.

4. Press number pads to enter desired cooking time.

• For example, to heat for 2 minutes 30 seconds,

5. Press desired power level pad to change power

level.
• If a power level pad is not pressed, oven defaults to

• For example, pressing MEDIUM 50% pad sets

oven to 50% power.

• Display shows current power level if other than 100

percent power.

6. Press TIME ENTRY pad.

• Display briefly shows "STAGE 2" . Then cook time

and power level for stage show in display.

• Repeat steps 5-6 to create additional stages.
