Memory program entry Note: 1. (For R-21LTF) If you want to set memory 11-20, press the desired number pad twice. 2. If the cooking time is over the maximum time, the display will show “EE 9”. See page 11. 3. At step 1, no audible signal will be heard when the SET pad is touched the first time. An audible signal will sound when the SET pad is touched the second time. You can change memory programs for memory banks. See time cooking on page 11. R-21LTF Memory banks 20 Cooking stage Memory NO.1 -10 max.
Memory check Checking magnification * Suppose you want to know the magnification factor for double quantity in memory 1. You can check the information programmed into each memory. Checking time and power level Procedure * Suppose you want to know the information programmed into memory 1, programmed for 4 minutes at 60% for the 1st stage and 2 minutes at 30% at the 2nd stage. Procedure CHECK 1 Touch CHECK pad. Display 2 Touch DOUBLE QUANTITY pad. NO. NO.
MANUAL OPERATIONS Time cooking R-21LTF R-21LVF Your oven can be programmed for up to 3 cooking sequences and has 11 preset microwave power levels. Your oven can be programmed for only one stage on 100% power level with a maximum of 30 minutes. Follow steps 1 and 3.

Note: If you do not open the door when an audible signal sounds, the defrosting cycle will continue and the defrosting time will count down to 0. TIPS: Allow foods to stand a few minutes after defrosting to equalize the temperature for better cooking results.
Counter check To clear the number of times Set counter to "0" before using oven for the first time. See next column. Each number of times can be cleared by touching SET pad during checking mode. To check times used * Suppose you want to clear the times of memory 1. You can check total times oven, each memory, manual cooking and Express Defrost were used. Total count Procedure Touch CHECK pad twice. CHECK Count of memory Touch each number pad of memory.

COOKING GUIDE Utensils METAL 1) Frozen Precooked Foods in Foil Containers When cooking foods in foil containers, the container should be no more than 1/2" (1.3 cm) deep. The best method to use is, after removing the foil cover, return the metal container to the paper box or package it came in and place this entire unit in the microwave oven. There must be more food than metal, and the metal container must not touch the oven walls.
Guidelines for microwave heating Several factors should be kept in mind when selecting utensils to be used for microwave heating. 1. A plate with a narrow rim of about 1/2-inch (1.3 cm) is recommended. This keeps the food all at the same level for more even, uniform heating. 2. Casseroles and sauced items should be heated in straight sided containers. 3. Containers should be chosen to be large enough to contain foods as they expand with heating. Milk products are especially subject to boil-overs. 4.
Casseroles 1. Arrange casseroles with larger pieces or bulk of food around the perimeter of the casserole; depress in center. 2. Casseroles should be heated covered with a non-metallic cover or plastic wrap except casserole with crusts. If tightly covered, puncture plastic wrap or loosen at one corner so steam can escape. Be careful when removing plastic wrap; pull wrap away from you with the tines of a fork. 3. Cover casseroles evenly with sauce or gravy before refrigerating. Vegetables 1.

REMINDERS 1. Do not operate the oven empty. Either food or water should always be in the oven during operation to absorb microwave energy. 2. Limit use of metal to those specific examples given in this booklet. Generally, metal should not be used in the microwave oven during operation. 3. Do not heat eggs in the shell. Pressure will build up inside the shell and it will explode. Do not reheat cooked eggs unless they are scrambled or chopped. Puncture the yolk before heating eggs. 4.
