The operations of DSP and DIR etc are able to checked by the information displayed on FL in this debug mode.
This information will help to analysing digital audio no sound trouble.
To set in Debug mode
1. Press and hold down
DISPLAY
button, then press
STANDBY/ON
button while the unit is powered on.
The version number of microprocessor is displayed only for 3 seconds.
2. Press
+
(
TONE)
button within 3 seconds above, the version number of DSP will be displayed for 5 seconds.
2. Press
DISPLAY
button while the DSP version is displayed. The status of DSP and DIR etc will be displayed.
To exit
Press STANDBY/ON button.
