LIMITED WARRANTY SHARP ELECTRONICS CORPORATION warrants to the first end-user purchaser that this Sharp brand product (the “Product”), when shipped in its original container, will be free from defective workmanship and materials, and agrees that it will, at its option, either repair the defect or replace the defective Product or part there of with a new or remanufactured equivalent at no charge to the purchaser for parts or labor for the period(s) set forth below.
IMPORTANT SAFETY INSTRUCTIONS When using electrical appliances basic safety precautions should be followed, including the following: WARNING - To reduce the risk of burns, electric shock, fire, injury to persons or exposure to excessive microwave energy: 1. Read all instructions before using the appliance. 2. Read and follow the specific “PRECAUTIONS TO AVOID POSSIBLE EXPOSURE TO EXCESSIVE MICROWAVE ENERGY” on page 1. 3. This appliance must be grounded. Connect only to properly grounded outlet.
SERVICE CALL CHECK Please check the following before calling for service! 1. Plug the power cord into a three-pronged electric-outlet. (See page 5) 2. Place one cup of water in a glass measure in the oven and close the door securely. A. Does the oven light come on? Yes _______ No _______ B. Does the cooling fan work? (Put your hand over the back ventilating opening.) Yes _______ No _______ C. If "No", please check wall outlet and circuit breaker. 3. Touch these pads: SELECTATIME 1 0 0 START A.
GROUNDING INSTRUCTIONS GROUNDING INSTRUCTIONS This appliance must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. This appliance is equipped with a cord having a grounding wire with a grounding plug. The plug must be plugged into an outlet that is properly installed and grounded. WARNING – Improper use of the grounding plug can result in a risk of electric shock.
INSTALLATION INSTALLATION Because your Sharp Commercial Microwave Oven will be used frequently, place it so that there is easy access for all users. 1. Be sure all electrical requirements are met. See page 5. 2. Exhaust vents are on the back of the unit near the top. Install the unit at least 2 inches away from the nearest wall to permit adequate ventilation for proper cooling and air flow in the oven. 3. Install the unit where no excessive heat or steam are generated.

BEFORE OPERATION * Before operating your new oven, make sure you read and understand this operation manual completely. 1) Plug in the oven. * The digital display will then show . 2) You can input the pads only when the door is closed. 3) Oven light and fan motor work for 1 minute whenever the door is opened or after cooking. 4) The program and the check are canceled when any pads are not touched for more than 3 minutes.
3. If the cooking time is over the maximum time, the display will show “EE 9”. See page 11. 4. At step 1, no audible signal will be heard when the SET key is touched the first time. An audible signal will sound when the SET key is touched the second time. Memory program entry You can change memory programs for memory banks. See time cooking on page 11. Memory banks 20 Cooking stage Memory NO.1 -10 max. 3 stages Setting magnification factor Memory NO. 11-20 max.
Checking magnification Memory check * Suppose you want to know the magnification factor for double quantity in memory 1. You can check the information programmed into the memory. Checking time and power level Procedure * Suppose you want to know the information programmed into the memory 1, programmed for 4 minutes at 60% for the 1st stage and 2 minutes at 30% for the 2nd stage. Procedure Display CHECK 1 Touch CHECK pad. NO. CHECK DOUBLE QUANTITY Display NO.
MANUAL OPERATIONS Time cooking Multiple sequence cooking Your oven can be programmed for up to 3 cooking sequences and has 11 preset microwave power levels. * Suppose you want to cook for 4 minutes at 60 % for 1st stage and then continue to cook for 2 minutes at 30% for 2nd stage.
Express Defrost Use EXPRESS DEFROST to defrost meat and poultry faster and better. Calculate total defrost time from chart below. Express Defrost can be programmed for a maximum of 90 minutes. * Suppose you want to defrost one pound of lamb chops for 3 minutes and 30 seconds. Procedure TIPS: Allow foods to stand a few minutes after defrosting to equalize the temperature for better cooking results. Display Check food after standing. If additional time is needed, continue to defrost with time cooking.
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. Counter check * Suppose you want to clear the times of memory 1. You can check total number of using times, times of using each memory, times of using manual cooking and times of using EXPRESS DEFROST. Total count Procedure Touch CHECK pad twice.
OTHER CONVENIENT FEATURES Signal setting Demonstration Mode There is a choice of 2 different sounds and no sound on your oven. To demonstrate, touch SELECTATIME, 0 and then touch START and hold for 3 seconds. Cooking operations can now be demonstrated with no power in the oven. The timer will count down rapidly. To set signal, touch the SET pad twice within 2 sec., and then touch the SIGNAL pad continuously until you hear desired tone. To cancel, touch SELECTATIME, then 0 and STOP/ CLEAR.
CARE AND CLEANING Oven interior 1) For easy cleaning, wipe any spatters or spills with a soft damp cloth or sponge at the end of each day. For heavier spills, use mild soap and wipe clean with a soft damp cloth. 2) At least once a week, remove the splash cover and wash in a mild detergent solution. The splash cover is located in the top of the oven and may easily be removed. REMEMBER TO UNPLUG THE POWER CORD. Remove two thumb screws (A) as shown in Fig. 1. Then remove the splash cover from the oven.
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-inch (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 casseroles 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.
