Control lock

To prevent accidental use or inadvertent setting
changes, the hob has a control lock which disables
controls. Disconnecting the appliance from the mains will
deactivate the control lock.
To activate the control lock
Turn on the hob, set a power level if required, and then touch and
hold the lock sensor (10) for approximately 1 second. The hob should
beep and the LED above the sensor should illuminate. The hob will
now be significantly more protected from inadvertent use. The on/off
sensor (9) can still be used to switch the hob off but when it is turned
back on the lock will still be active.
To deactivate the control lock
To switch off the lock, switch on the hob if necessary and then touch
and hold the lock sensor (10) for approximately 1 second. The hob
should beep and the LED above the sensor should extinguish. The
hob should now be usable as normal.

Safety key lock

To further protect the hob from accidental use or to help prevent
children from activating the hob, it also features a more intricate safety
key lock.
