SUITABLE OVENWARE
To cook/defrost food in a microwave oven, the
microwave energy must be able to pass through
the container to penetrate the food. Therefore it is
important to choose suitable cookware.

TROUBLESHOOTING
If you think the oven is not working properly there
are some simple checks you can carry out yourself
before calling an engineer. This will help prevent
unnecessary service calls if the fault is something

4. After 1 minute does the audible signal sound?
5. Is the water in the cup hot?
If you answer “NO” to any question first check that
the oven is plugged in properly and the fuse has not
blown. If there is no fault with either, check against
the troubleshooting chart on the following page.

• Repairs and Modifications: Do not attempt to
operate the oven if it is not working properly.
• Outer Cabinet & Lamp Access: Never remove
the outer cabinet. This is very dangerous
due to high voltage parts inside which must
never be touched, as this could be fatal.
Your oven is not fitted with a lamp access cover.
If the lamp fails, do not attempt to replace the lamp
yourself, call a SHARP approved service facility.

IMPORTANT:
If the display is blank and has gone dark, even if the
power plug is properly connected, the oven may be
in Energy Save Mode. To cancel it, open and then
close the oven door, see page 10.
