User Manual Panasonic NN-CF853WBPQ Premium Combination Oven

The beeping sound cannot be turned off on any of our
microwave ovens. It is a safety feature to inform of cooking progress and to help prevent accidental misoperation when pressing buttons. Full details of beeping sounds are given in the operating instructions for each model.

The unit has a cooling fan, which will continue to run after
cooking to cool down the elements inside, the fan will stop
automaticaly when it is finished. This does not indicate a fault and no microwaves will be released during this operation.
You can also continue to use the oven normally during this time if you wish to cook another item.

Chaos defrost is a system that improves the auto weight defrosting process.
Chaos defrost uses random pulses of power to achieve a quicker and more even defrost within the food. This would only be used for Bread, Meat Items or Meat Joints.

All the microwaves have a bulb inside and they are supposed to be on while the microwave is in use and the door is open.
If your microwave light no longer operates then the bulb may need to be exchanged, we recommend this to be carried out by an authorised service agent, those in your area can be found on our Website.
There is no way to turn the light off while using the microwave.

Exterior oven surfaces, including the air vents on the rear and bottom of the cabinet, and the oven door will get hot during GRILL, CONVECTION and COMBINATION. Additionally using microwave power for long time settings can produce excess steam leading to the cabinet becoming hot so please take care when opening or closing the door and when inserting or removing food and accessories. Always follow the operating instructions and ensure the unit is installed with adequate ventilation space to prevent overheating.
Setting the power and time too high for your food load can also lead to overheating and could eventually cause malfunction, or reduce the life of the product. Please always check whether food needs to be cooked on high power and for the length of time set?

The door is designed to stop microwave energy for escaping, however does not need to be airtight in order to do this. There are small holes around the door seals because the temperatures on either side of the door differ (i.e. the air in the interior cavity is hotter than that on the outside of the microwave). This causes air expansion in the door cavity, so there are air release holes in the seal of the door to accommodate this so the pressure does not build.

Please see the operating instructions for your model as it can be different from model to model.
