Don't turn the [POWER] switch off while executing
this test, the DG80-112 won't set up at normal mode
by no data in the Flash Memory.
(Test Contents)
The Flash Memory Erase/Write check is executed
automatically.
When the check is started, the LED display shows
from “70” to “73” successively. When all the LEDs
light simultaneously, the Flash Memory Erase/Write
check is finished. Then the DG80-112 selects the
next test no., so the LED display shows “8”.
(Error Number)
E0, E1 : Flash Erase Error
E2, E3 : Flash Write Error
8. Sound Check
Before executing this sound check, the idling
adjustment, the output wave adjustment and center
voltage adjustment must be finished. the three
adjustments can be done while the LED display
shows “8”.
(Idling Adjustment)
1. Set the idling adjustment volume (VR303) at
minimum.
2. Connect the 4 ohm load to the speaker terminals.
3. Set the output volume at minimum.
4. Adjust the VR303 so that the DC voltage between
the terminals of the RA301 should be 5 +/-1 mV.
(Output Wave Adjustment)
1. After adjusting the idling adjustment, set the
OUTPUT VR at maximum.
2. When the signal of -2 dBm / 1 kHz is inputted from
the RETURN terminal, adjust the VR 301 (4.7 k
ohms) so that the wave shape should be a sine wave
symmetrical for upper and lower as below.
(Center Voltage Adjustment)
1. Adjust the VR302 so that the voltage of the output
circuit (RA301) should be 38 +/- 2 V.
* By adjusting the output adjustment and the center
voltage adjustment alternatively, search the best point.
After finishing the adjustments above, press the
[RECALL] key when the LED display shows “8”.
The Sound Check is started.

(Test Contents)
The DG80-112 sets the conditions for the signal
Sound Check through the analogue circuit, the A/D
converter, the DSP-3 and the D/A Converter.
When the Sound Check is started, the LED display
shows “81”. The Sound Check has two conditions.
If the [RECALL] key is pressed when the LED
display shows “81”, the LED display changes to
“82” and the condition changes to the next as below.
81 : DSP3-1
82 : DSP3-2
Check the following items in each condition of “81”
and “82”.
* 0 dBm = 0.775 V Load = 4 ohms
If the Sound Check has been finished, press the
[RECALL] key when the LED display shows “82”.
The LED display shows “9”.
