In the delivery state the components of the FS20 wireless control system (a
wireless switch socket, for example) do not respond to remote control com-
mands from the flush-mounted battery transmitter.  They must first be ad-
dressed according to the instructions provided in the respective device’s user
manual.

Only afterwards can the functions be controlled.

Buttons are pressed briefly (to switch) or for longer than 0.4 seconds (to dim), as required.

Pressing a button briefly (for fewer than 0.4 seconds) sends a ‘TOGGLE’ command
(changing between two switch states).

If a button is pressed for longer than 0.4 seconds, the corresponding dim command (‘DIM-
UP & DIM-DOWN’) is sent until the button is released.

When the ‘DIM-UP & DIM-DOWN’ command is issued, a lamp is dimmed up to the
maximum and then dimmed down to the minimum, etc.

The ‘dim direction’ is always the opposite direction to the command that was previously
sent. If, for example, the last command caused a lamp to dim up, then pressing the button
again would result in the lamp dimming down.

Now you can program and operate the basic functions of the FS20 components.
