Genuine Toshiba owner's manual. Couldn't really ask for more. And written in understandable English in contrast to a few recent experiences I have had with manuals for other equipment other than Toshiba but made in China and written in "Chinglish"!

Automatic defrost by weight
1. Open the door, place the food on the turntable. Close the door. 2. Press the Power setting button dEF (Automatic Defrost) is reached. 3. Set the desired weight by pressing the required âweight buttons. 4. Press Start (The oven begins defrosting.)
To turn off the oven during automatic defrost mode, simply touch the â Start / Reset â button. Note: After use, be sure to press the â Start / Reset â button whilst the door is open as this will ensure that you have reset the microwave.
During Auto Defrost the oven will automatically select the required microwave power and defrost time. The maximum weight setting for Auto Defrost is 2.0Kg (2000g) If you wish to defrost any item of food which is larger than this, then it is recommended that the item be split into two or more pieces of equal size. If the item cannot be split then you should not defrost it in this microwave.
Example: To automatically defrost 1200g of food.
1. Press the â Power â button six times ( â dEF â should now be showing in the display window ). 2. Press the â 1min / 1.0Kg â button once ( â 1.0 â should now be showing in the display window ). 3. Press the â 10 Sec / 01.Kg â button twice ( â 1.2 â should now be showing in the display window ). 4. Press start. The Oven will now defrosting.
1. It is better to underestimate defrosting time if you are unsure. Food will continue to defrost during the standing time. 2. Separate food as soon as possible. 3. Turn large items, e.g. joints, halfway through the defrosting time. 4. Remove any thawed food as soon as possible. 5. Remove or open any packaging before defrosting. 6. Place food in a larger container than that which it was frozen in, this will allow for easy stirring. 7. Begin thawing poultry, breast side down and turn over halfway through defrosting time or at pause. Delicate areas such as wing tips can be shielded with small pieces of smooth foil. 8. Standing time is very important, particularly for large, dense foods which cannot be stirred to ensure that the centre is completely defrosted before cooking.
