System error displays
Whenever the system detects an error, it displays the corresponding error code in the
LED display field of the front panel (providing the communication server is still powered
and the display is working).
These errors are not defined yet.
In the event of sporadic errors check the installation for earth loops.

Operating state of the Mitel DECT radio units
Each radio unit is equipped with 3 LEDs. The operating state the radio units is indi-
cated by different colours and flashing sequences in cycles of 1 s, specifically by one of
the two outer LEDs on the SB-4+ and by both outer LEDs on the SB-8 / SB-8ANT (sep-
arately for each DSI bus). Each character (G, R or -) corresponds to 1/8 of a second.
Example:
During the synchronization phase GGGGRRRR the LED flashes periodically.
1/2 second green, 1/2 second red.
