Maximum Cooking Time; Other Convenient Features; Demonstration Mode; Monitor - Sharp R-1900J Operation And Cooking Manual

Maximum Cooking Time

1. 100%~60% power level : the total cooking time of all cooking stages is maximum 60 minutes.
2. 50%~10% power level : the total cooking time of all cooking stages is maximum 120 minutes.
3. Multi Stage Cooking : the Maximum Cooking Time is limited by the following calculation. Each stage has 100~60% power
level or 50~10% power level.
Maximum Cooking Time Calculation
Total Cooking Time of
100~60% Power Level
* Suppose you want to cook 5 minutes at 100% for 1st stage, 15 minutes at 80% for 2nd stage, 40 minutes at 30% for
3rd stage and 20 minutes at 10% for 4th stage. In this case actual Cooking Time is 80 minutes, and the calculated
time is 50 minutes, see the calculation below.
[5min + 15min] + [(40min + 20min)/2]
4. 0% power level : maximum 99 minutes and 99 seconds can be input at one stage (max. 4 stages).
5. Express Defrost : the maximum defrosting time is 90 minutes. See Maximum Cooking Time Calculation above.
