  3. Set the clock before starting the oven.
  4. The clock is cleared when the power supply cord is disconnected or at power failure.

HOW TO SELECT MICROWAVE COOKING POWER THIS OVEN IS RATED AT 800 WATTS (IEC705)

The microwave oven provides six power levels. Select the power level suitable to the food by using the numeric pads inconjunction with instructions on page 11.

They are as follows:

HIGH 800W power Press 'Time' Pad

M.HIGH 560W power Press Pad 7

MEDIUM 400W power Press Pad 5

M.LOW 320W power Press Pad 3

LOW 120W power Press Pad 1

REST No power Press Pad 0

HIGH - M.HIGH ( )

Select these power levels for reheating, cooking, boiling and steaming.

M.HIGH - MEDIUM ( )

Select these power levels for foods that benefit from slower cooking, such as joints of meat and delicate fish dishes.

MEDIUM - M.LOW ( )

Select these power levels for casseroles, milk puddings and egg dishes.

LOW( )

Select this power level for softening butter or keeping food warm.

HOW TO DETERMINE MICROWAVE COOKING TIME

The required cooking time varies with the weight and density of food, temperature of the food, and the container to be used. Since food that is heated too much cannot be made good, set the cooking time shorter than the estimated one and add more time if necessary after checking the state of the food.

1) The cooking time is roughly proportional to the quantity of food. If the quantity is doubled, the cooking time should be a little less than doubled, and if the quantity is reduced to half, the cooking time should be reduced to a little more than half.

The smaller the volume of the food, the shorter the time required.

2) Food that has been stored in a refrigerator is cooler than food kept at room temperature and therefore requires longer cooking time-approximately 1.3 of normal recommended time.

3) Food that is thin or light textured is heated more quickly than thicker or denser foods.

Thinner pieces of food will be cooked/heated up quicker.

1) Food with skins such as potatoes and tomatoes should be pierced or slit before cooking.
2) Vegetables should be cooked in a covered container to retain moisture.
3) Popcorn should be made in a special popcorn pan for the microwave oven.
4) After cooking or reheating food needs to stand for a while to allow the heat to equalize within the food.
This can take place in the oven or outside.

HINTS FOR DEFROSTING

1) To defrost irregular shaped food evenly, wrap thin parts of the food with a piece of aluminum foil.

Aluminum foil
HITACHI MR8140 - HINTS FOR DEFROSTING - 1

This will shield the sensitive area from starting to cook whilst the rest is still defrosting.

2) Microwaves cannot penetrate through to the centre of a large joint of meat, so allow it to stand at room temperature for a while before cooking.

A piece of meat weighing 1.5 kg/3 lb needs to be left at room temperature for 45 to 60 minutes after being defrosted by the microwave oven.

HITACHI MR8140 - HINTS FOR DEFROSTING - 2

3) To defrost the food evenly, turn over or rearrange the food in the oven halfway through the defrosting time.

HITACHI MR8140 - HINTS FOR DEFROSTING - 3

4) Pieces of steak, meat, or chicken frozen together should be separated as soon as they start defrosting.

5) Meat portions, with the exception of pork or chicken can be defrosted and cooked without standing in between.

6) Food that is covered, will defrost and cook more quickly and retain its moisture.

1 Open the door and put the food in the oven.

  • The food must be placed on the turntable. If the food protrudes beyond the turntable, it cannot rotate smoothly.
  • When closing the door, push it against the oven till it clicks. If the door is not closed securely, the microwave oven may not operate.

10. NOTES ON USE

IMPORTANT:

If food is not cooked or PIPING HOT RIGHT THROUGH, even after following the recommended times, then cook it until it is; just as you would with conventional cooking.

Where possible, STIR OR RE-ARRANGE FOOD during cooking for even heating.

Always OBSERVE STANDING TIMES before testing, to allow the heat to spread evenly throughout the food.

  1. When using metal cooking tools to stir or re-arrange food, do not let them touch the oven walls, door surround, turntable.

- Arcing will occur, and could crack the glass or damage the turntable.

  1. Caps must be removed from jars, sealed packages of food should be opened, and shelled food should be cracked before heating.

- Capped jars, sealed packages, and shelled food may explode, and are dangerous.

  1. Do not heat a small amount of food for a long time.

• The overheated food may scorch or burn.

  1. Food in foil containers should be transferred to a suitable microwave container for heating or cooking. Foil containers reflect microwaves away from the food.

  2. Do not use a thermometer during cooking.

• Take the temperature of the heated food after it has been removed from the oven. If the thermometer is used in the oven, it may be broken by the heat.

  1. Do not heat oil or greasy fried food.

- The food may be overheated because the temperature of oil cannot be controlled.

7 Do not put food heavier than 10 lbs on the turntable.

- The turntable cannot rotate when the food is too heavy, and that could cause damage to the oven.

  1. If food becomes charred from overcooking and smoke develops, keep the door closed and turn the oven off. Any possible fire will then be stifled.
  2. Certain foodstuffs with a low water-content, such as cooking chocolate and pastry with sweet fillings, must be heated cautiously; otherwise they may spoil or may damage the cooking container.
  3. Liquids may be heated and boiled in the microwave oven, but, as with any other form of heating liquids, great care should be taken. Please ensure that the liquid is left standing for at least 20 seconds in the oven after it is switched off. As always when handling boiling liquids, great care should be taken on removing the liquids from the oven. These considerations are particularly important when water is being boiled in cups, mugs, or vessels of a similar size as there is a risk that bubbles may combine to form a large bubble inside the container which may erupt and displace the water. The displaced boiling water could cause injury.
  4. Do not leave the oven unattended when food is heated or cooked in disposable containers of plastic, paper or other combustible materials. If smoke is observed, keep the oven door closed and switch off or disconnect the oven from the power supply.
  5. The oven is expanded by heat and the noise of expansion may be heard during heating, but that is normal.
  6. Use the microwave oven for the purpose of cooking only.
  7. Do not use the microwave oven for drying clothes or paper products, they may catch fire or smoulder.
  8. If a fire should occur in the oven, keep the door closed and cut off the power supply by disconnecting the power supply cord, any possible fire will then be stifled.

11. CLEANING AND CARE

  • It is important that the oven is cleaned frequently to avoid food splashes from being baked on.
  • Clean the microwave oven after turning off the power and pulling out the plug.

Oven

(Ceiling, walls, bottom, and inside of door)

Cover Mild detergent

Each time food has been cooked, wipe off the dirt or food splashes as soon as possible.

Greasy spots should be wiped off with a cloth soaked in mild detergent.

  • If dirt is left in the oven for a long time, it cannot be wiped off easily, it will hold the smell of the food, and may cause corrosion or rusting. Also, arcing may occur and the side cover may be scorched because the microwaves are concentrated on the food splashes.
  • If the side cover becomes too dirty to be cleaned, consult the Hitachi agent and replace it.
  • Check the microwave oven for any visible damage, such as a misaligned door, damaged door seals around the door or dents inside the oven cavity or on the door. Ensure that the door and door sealing areas are clean before use, clean with a mild detergent, water and a soft cloth. Do not use scouring pads, powder or other abrasive materials.

Roller Ring

HITACHI MR8140 - Roller Ring - 1

Always keep the roller ring clean.

When it is soiled with food splashes or grease, remove the food splashes or grease using a sponge or cloth soaked with mild detergent and wash it in water.

  • If food splashes are left on the roller ring, arcing may occur because the microwaves are concentrated on the food splashes.
  • Keep the roller ring in position in the oven except when it is to be cleaned.

Turntable

HITACHI MR8140 - Turntable - 1

When the turntable is soiled with grease or food splashes, remove the dirt with a sponge soaked in mild detergent, wash it in water, and dry it.

Cabinet

HITACHI MR8140 - Cabinet - 1

Wipe the cabinet with a soft cloth.

  • When the cabinet is heavily soiled, wipe it with a cloth soaked in mild detergent and then wipe off the mild detergent thoroughly with a clean damp cloth.
  • Do not splash water on the air outlets.

CAUTIONS

Do not rub the oven and accessories with a wire brush or sharp-edged tool.

HITACHI MR8140 - CAUTIONS - 1

The surface may become scratched.

Do not apply oven cleaner, benzene, or thinner to the surface of the panel or door.

HITACHI MR8140 - CAUTIONS - 2

The letters on the panel may fade, and the surface may lose gloss or may corrode.

12. BEFORE ASKING FOR REPAIR

Before calling the serviceman to repair the microwave oven, check the following points:

ProblemPoints to be checked
Food is not cooking.• Is the plug connected?• Is the circuit breaker off or fuse blown out?• Is the door closed securely?
Food not cooked enough.• Has the correct cooking power been selected?• Has the correct cooking time been set?• Has the food been left to "stand" for a sufficient period of time after cooking?
Arcing occurs in the oven or a cracking noise is heard.• Does the container of the food have a metal trim?• Is there a fork, metal cooking tool, or aluminum foil touching the oven wall?

If the problem cannot be overcome after the above points are checked and corrected, contact your nearest authorized service agent to repair the microwave oven.

The following conditions are normal in the microwave oven:

(1) The turntable may turn clockwise at one time and counter-clockwise at another time.The turning direction does not affect the result of cooking.
(2) The inside of the door and the oven walls are wet with condensation, and steam comes out not only from the air outlets but also from around the door.Food with a high water content may cause condensation.
