+ Light key and special key
Use the light- and special button "S" to activate
the optionally switching actuator. If you have
questions concerning the functionality please
ask your electrical installer.
Press the required key until you hear a confirma-
tion tone.
+ Internal call
As an option, the unit can be configured for
making internal calls. A maximum of 2 call ad-
dresses can be set.
The light key as well as the special key can be
configured for this function. A key that was
configured for an internal call can no longer be
used for switching a switch actuator.
To switch off the internal call function, press the
corresponding key until you hear a confirmation
tone.
Note
Each effective key function is signalized by a
LED above the ring tone on/ off key.
