The ‘FS20 TFK’ is immediately ready for operation with the factory settings. The transmission
signals are encrypted using a house code that is randomly assigned when the batteries are
inserted and the address group 11 (control of several receivers with one transmitter possible).

For the initial operation of the transmission path to the receiver, the house code and the
addresses must first be transmitted to the receiver.

• Set your receiver, based on the user manual of your particular receiver, in the address

programming mode.

• Now press buttons 1 or 2 (for channel 2: buttons 3 or 4) on the keypad of the ‘FS20 TFK’.

• Test the switching function by briefly pressing buttons 2 or 1 (channel 2: button 4 or button

3) on the ‘FS20 TFK’. The receiver should switch on or off.

• Now the ‘FS20 TFK’ is ready for operation with the factory settings.
