Self-diagnose function
1. Detection of abnormal power supply and voltage
When the power is turned ON, if an abnormality is detected during the signal input at the A/D port (IC901,
pin 2-5, 7) for one second continuously, the status will become STANDBY mode immediately.
When the power is turned ON again, detection of abnormal power supply and voltage will not be carried out
during the first 4 seconds.
Given below is a list of threshold values at the detection of abnormalities.
2. Initial setting on ship
To gain the initial setting on ship, put the power plug in the socket while pressing DOWN key and UP key
together simultaneously, then turn the power ON.
3. Test mode
To enter the test mode, put the power plug in the socket while pressing EFFECT key and UP key together
simultaneously, then turn the power ON.
Workings of test mode:
All FLs are turned ON for 3 seconds. (the FLs, which are divided in two groups, are turned ON alternatively)
Faster volume UP/DOWN operation can be achieved with the remote controller.
When the power is turned OFF, the test mode will be released.
The FL display returns to normal after the three seconds. Then the STANDBY LED is turned ON (flashing
ON and OFF for each one second) to show the present status being a test mode.
