1. Safety
Danger!
Repairs must be carried out by a qualified expert!
Incorrect repairs can be extremely dangerous for the user.
It is essential that you observe the following instructions in order to prevent electric shocks:
• The casing and the frame may be live in the event of faults!
• Touching live components inside the appliance may cause dangerous currents to flow through your
body!
• Disconnect the appliance from the mains prior to carrying out any repair work!
• When inspecting live parts, a residual current circuit breaker must always be used!
• The earthed conductor resistance must not exceed the resistance specified in the standard! It is vital
for ensuring the safety of persons and the functioning of the appliance.
• On completion of repairs, an inspection must be carried out in accordance with VDE 0701
[Association of German Electrical Engineers] or the corresponding regulations for your country!
It is essential that you observe the following instructions:
• The appliances must be disconnected from the mains prior to all repairs. If inspections must be
carried out on live appliances, make sure you use a residual current circuit breaker.
Attention!
Sharp edges: use protective gloves.
Components may be electrostatic!
Observe handling regulations!

2. General Information
Changing the specification or attempts to modify the product are dangerous. For your own safety spare
parts should be installed by an authorised, qualified specialist. The manufacturer accepts no liability for
damage which occurs as a result of improper installation or failure to observe currently-valid regulations
for this type of application. Please read through the installation instructions carefully prior to commencing
with work.
2.1 Safety instructions
2.1.1 General information on the hob
• Do not place empty pots and pans on cooking zones which have been switched on. Avoid boiling the
pots dry as there is a risk of the pots overheating!
• Take care when using simmering pans as simmering water may dry up unnoticed, resulting in
damage to the pot and to the hob for which no liability will be assumed.
• Overheated fats and oils may spontaneously ignite. Always supervise the preparation of food with
fats and oils. Never extinguish ignited fats and oils with water! Put the lid on the pan and switch off the
cooking zone.
• The glass ceramic surface of the hob is extremely robust. You should, however, avoid dropping hard
objects onto the glass ceramic hob. Sharp objects which fall onto your hob might break it.
• Take care when working with home appliances! Connecting cables must not come into contact with
hot cooking zones.
• The glass ceramic hob should not be used as a storage area.
• Do not put aluminium foil or plastic onto the cooking zones. Keep everything which could melt, such
as plastics, foil and in particular sugar and sugary foods away from hot cooking zones. Use a special
glass scraper to immediately remove any sugar from the ceramic hob (when it is still hot) in order to
avoid damaging the hob.
• Do not place combustible, volatile or heat deformable objects directly underneath the hob.
• Never use the cooking zones to heat up unopened tins of food or packaging made of material
compounds. The power supply may cause them to burst!
• Keep the sensor keys clean since the appliance may consider dirt to be finger contact. Never put
anything (pans, tea towels etc.) onto the sensor keys!
• Avoid repeated burning of contaminations.
2.1.2 Concerning persons
• This appliance is not intended to be used by persons (including children) with physical, mental or
sensory impairments or by persons (including children) who lack the required experience or know-
how, unless such persons are supervised by a person responsible for their safety or have been given
instructions on how to use the appliance by a person responsible for their safety.
• Children should be supervised in order to ensure that they do not play with the appliance.
Attention! The surfaces of the heating and cooking zones become hot during use. Keep small
children away at all times.

6. Touch-Control operations
6.1 Putting the hob into operation
The displays are switched on for approx. 1 second when the power supply is switched on. The software
versions of the processors will then be shown for approx. 3 seconds.
A "P" will appear in the timer display.
The software version of CPU2 will appear in the 2 power setting displays.
The software version of CPU1 will appear in the 3. and 4. power setting displays.
The hob type setting will then be shown (only for hobs with 5 cooking zones):
"t" will appear in the timer display.
The type number will be shown in the power setting display.
"8752"
"8852"
"9852"
During this phase basic calibration of the keys is carried out!
Important: The sensors must not be covered up!
Once calibration has been completed, the hob displays will show "OFF". This means that the operator
needs to press the OFF sensor in order to confirm that the sensors were not covered up. If this is not
confirmed, calibration should be repeated by switching the power off and then on again.
6.2 Turning the hob on
The hob is switched on by pressing the ON sensor for approx. 1 second. The corresponding LED will
light up. A short signal will also sound in confirmation.
If no cooking zone is activated within 10 seconds of being switched on, a continuous signal will sound
for another 10 seconds. If no cooking zone is activated within this time either, the hob will switch off.
6.3 Power settings
The heating power of the cooking zones can be set at various power levels. When the slider is pressed
for the first time (the cooking zone must be switched off beforehand), it will react to the quickstart key.
Depending on where it is touched, one of three settings will be selected:
Left: Power setting 1
Middle: Power setting 5
Right: Power setting 9
After this, touching the slider will set the power level, depending on where and how it is touched.

6.4 Selecting the power setting by pressing the key
The ceramic glass hob is operated with touch control sensor keys. The sensor keys are operated as
follows: lightly touch a symbol on the surface of the ceramic glass plate. A buzzer will indicate when the
controls have been operated correctly. The touch control sensor key will then be indicated as “key”.
A higher or lower power setting can made between 1 and 9.
If you leave your finger on the key, the power setting will be raised or lowered after a short delay,
depending on the position of your finger. The adjustment speed is calculated dynamically from the touch
position. If your finger leaves the area shown on the glass to the left or to the right, incrementation/
decrementation will be deactivated.
6.5 Worth knowing about the slider (touch control)
In principle, the slider functions the same as the touch controls; the only difference is that you can put
your finger on the glass ceramic surface and then move it around. The touch control recognises this
movement and raises or lowers the display setting (power level) in accordance with the movement.
The “slider” is given this name because of the pushing or sliding movement.
.
What must be observed when operating touch controls?
Your finger should not be placed flat onto the glassceramic surface in order to avoid adjacent keys/touch
controls from reacting by mistake.
Press the slider lightly or move your finger around
You can press the touch control very lightly with your finger; when this is done the setting on the display
(power level) will gradually change.
When you put your finger on the touch control and then move it to the left or right, the display setting will
change progressively. Sliding your finger from plus to minus (or from minus to plus) will activate the
slider function. This function will lock the other two functions. A quiet signal indicates that the slider
function is active.
Sliding your finger from left to right will raise the power settings by 1 – 3 levels; sliding your finger from
right to left will lower the power setting by 1 – 3 levels.
The slide function must be carried out at a certain rhythm, since the sliding of afinger must be recognised
within 0.4 seconds. The sliding movement must also be completed within one second. Fewer power
settings will be changed if you slide your finger over the sensor too quickly or if you interrupt the sliding
movement.
