DSP/EEPROM Test
When the unit enters the Test Mode, DSP and EEPROM Test starts automatically.
The three LEDs at the center of the panel light up in the sequence of LEFT → CENTER → RIGHT to indicate the progress of the testing, then go dark in this
sequence of LEFT → CENTER → RIGHT.
If the test result is OK, testing is completed in a very brief time, and the LEDs are automatically initialized for the following Switch and LED Test (p. 24).
If the test result is NG (not OK), one of the LEDs shown in the table below lights up to indicate the corresponding device where the problem occurred.
* If the test result is NG (not OK), execution cannot advance to the next test item.
Switch and LED Test
Carry out operations in the sequence shown in the table below and verify the status of the corresponding LEDs.
* If an error is made in the order of operations, or of a test is failed, execution cannot advance to the next operation.
* When operating the OUTPUT POWER switch, make a definite stop at each position. If the switch is moved too rapidly, without sufficient stopping, its operation might be
ignored.
In this case, return the switch to its original position and redo the operation.
o: lights, *: flashes, -: goes off
Pulling out the plug from AUDIO IN makes execution advance automatically to the next test item.
