LEARNING THE NEW TRANSMISSION CODE
Once the transmission code is changed in the remote control unit, the electronic central unit of the
cooker hood must be made to set the new code in the following way:
Press the main power-off button on the hood and then restore power to the electronic control
unit. Within the next 15 seconds, press the Light Button to synchronise the central unit with
the code.
WARNING:
The battery should be replaced every year to guarantee the optimal range of the transmitter. To
replace the battery, take the plastic lid off, remove the battery and replace it with a new one,
observing the correct battery polarities. Used batteries should be discarded in special
collection bins.
TIMING

› External motor models are equipped with remote motors that, as for internal motor versions,
include a timer device that switches down the speed when it exceeds 650m³/h. (See
External Motors Instructions). Remote motors, whose air capacity exceeds 650m³/h at both
4th and 3rd speed, will have the following by default timer control functions: The speed is
