4.1 LED STATUS
The AUDIO MODULE has two DUO LEDs (Power/Boot and Status). Each DUO LED has a green and a
red LED. The upper DUO LED shows the state of Power/Boot, and the lower DUO LED the state of
the AUDIO MODULE.
The green “Power/Boot” LED lights up as soon as the AUDIOMODULE is supplied with power.
Two or three seconds after the power is connected, this LED changes to red and starts flashing.
Once the boot-up process is complete, this LED changes back to green.
After the AUDIO MODULE has booted up, the status LED flashes continuously with two quick pulses
followed by a short pause.
This flashing also indicates the load level on the AUDIOMODULE: the higher the frequency of the
flashing LED, the greater the load on the AUDIOMODULE.
The AUDIO MODULE now requires 2 minutes to boot up.
