CHAPTER 4. PRODUCT FUNCTIONS

• The ceramic hob caters for all kind of cooking, with its radiant heat cooking zones and its electronic touch controls and multi-functions, making it the ideal choice for the modern family.
- The ceramic hob is extremely user-friendly, durable and safe.

CHAPTER 5. SPECIAL FUNCTIONS

PROTECTION FOR OVER-HEATING

A sensor monitors the temperature in the cooking zones. When the temperature exceeds a sefe level, the cooking zone is automatically switched off.

RESIDUAL HEAT INDICATOR

When the hob has been operating for the same time, there will be some residual heat. The letter 'H' appears to warn tou that it is too hot to touch the surface.

AUTO SHUTDOWN PROTECTION

Auto shut down is a safety protection function for your ceramic hob. It shut down automatically if ever you forget to turn off your cooking. The default working times for various power levels are shown in the below table:

Power level 1~2	3~4 5 9
Default working timer (min)	360 300 240	90

If the electronic control detects a button being held down for approx 10 seconds it will switch off automatically. The control sends out an audible error signal to warn the sensors have detected the presence of an object. The display will indicate an error code ER03 if the hob is still hot. The display 'H' and ER03 flash alternatively.

CHAPTER 6. BEFORE USING YOUR HOB

• Remove any protective film that may still be on your Ceramic hob.

CHAPTER 7. USING THE TOUCH CONTROLS

• The controls respond to touch, so you don't need to apply any pressure.
• Use the ball of your finger, not its tip.
• You will hear a beep each time a touch is registered.
  • Make sure the controls are always clean, dry, and that there is no object (e.g. a utensil or a cloth) covering them. Even a thin film of water may make the controls difficult to operate.

CHAPTER 8. CHOOSING THE RIGHT COOKWARE

Do not use cookware with jagged edges or a curved base.

Three identical cooking pots with crossed-out X marks, no text or symbols present

Make sure that the base of your pan is smooth, sits flat against the glass, and is the same size as the cooking zone. Use pans whose diameter is as large as the graphic of the zone selected. Using a pot a slightly wider energy will be used at its maximum efficiency. If you use smaller pot efficiency could be less than expected. Pot less than 140 mm could be undetected by the hob. Always centre your pan on the cooking zone.
