3 Function

The MP3 radio chime with light flash serves as an audible and visu-
al signal actuator reporting various states in the HomeMatic system.
Signalling commands can be sent via taught-in sensors (e.g. push-
button, remote control) or a central control unit (CCU1). As such,
the actuator described can be used as a doorbell, a burglar alarm
or similar.
Furthermore, audio files stored in the memory can be used for au-
dible signalling. The device is supplied with a default audible signal
stored in the memory.

Audible and visual signals can be output simultaneously.
There is only one core function for direct teach-in. The visual
signal will output the audio file no. 001 six times. If no SD-
card was inserted while teaching the device in, the signal will
be played back in full once. Other options (e.g. status display
by means of light flash lighting up permanently) can be set via
the central control unit.

5 General information about radio operation

Radio transmission is performed on a non-exclusive transmission
path, which means that there is a possibility of interference occur-
ring. Interference can also be caused by switching operations, elec-
trical motors or defective electrical devices.
The range of transmission within buildings can differ greatly
from that available in the open air. Besides the transmit-
ting power and the reception characteristics of the receiver,
environmental factors such as humidity in the vicinity have
an important role to play, as do on-site structural / screening
conditions.
