4. LCD check
Perform the tests for the following four display patterns. Shift the pattern
using the [PAGE<] and [PAGE>] buttons. Shift the test pattern to the previous
one or the next one by pressing the [PAGE<] or [PAGE>] button, respectively,
to perform tests for the four patterns.

fig.3-4d_70
Check that all the LCD dots remain on all the time or off all the time during the
test.
Check that pattern contrast varies when the [VALUE] knob is rotated
clockwise and counterclockwise. Then, check if the pattern can be identified
when the contrast is set at maximum and minimum.
* When the LCD check ends, contrast returns to the standard value.
5. SW/LED check
In this test, all LEDs on the front panel are turned on . (The LCD screen
displays boxes located so as to represent the switches at their respective
relative positions.) The LCD screen displays ten boxes that mean swithes on
the front panel.
1. Check that the LCD screen displays box symbols only and all LEDs are
on.
2. Press the switches one by one to check that the box symbol on the LCD
changes to a point symbol. And check if the LED for the pressed switch
goes out.
fig.3-5a_65
3. After pressing all the switches, check that the LCD displays point
symbols only, and that all the LEDs are out.
fig.3-5b_65
6. Encoder check
In this test, the LCD displays the value proportional to the angular position of
the [VALUE] knob. At the beginning of the test, the displayed value is 0. Turn
the [VALUE] knob clockwise to increase the displayed value and to make the
tone generator produce the sound. Then, turn the [VALUE] knob
counterclockwise to decrease the displayed value. Check the output sound
through the headphones to see if chattering occurs.
fig.3-6_65
1. Turn the encoder clockwise to increase the value displayed on the LCD
and to make the tone generator produce the sound. Make sure that the
displayed value changes proportional to amount the encoder is rotated.
(Change the value from 0 to 23). And check the out put sound.
2. Turn the encoder counterclockwise to decrease the value displayed on the
LCD and to make the tone generator produce the sound. (Change the
value from 23 to 0)
If chattering occurs, for example, one click may make two sounds or more. and
the clockwise-sound may be produced when the encoder is rotated
counterclockwise. In this test, make sure that the above errors do not occur.
7. Sound check
In this test, check the DA converter and L and R separation of the stereo output
signals by producing the sound with the built-in tone generator.
Check that no sound distortion occurs and that there is no mixing of the right
and left signals.
Since the same signal is output to all of the OUTPUT 1/2 and DIGITAL OUT
terminals, change the speaker connections to check all output terminals.
For DIGTAL OUTPUT, connect the output of the external device to the
speaker to check. Change the connection of the optical and coaxial cable inputs
of the external device to check both inputs.
fig.3-7_65
1. Connect the L and R of OUTPUT to the respective speakers. Connect the
DIGITAL OUTs to the external device.
2. Press the respective buttons of output channels to produce a sine wave
sound.
3. Change the OUTPUT terminals. Conduct (2.) above to check the newly
connected terminals. Check the headphones to which the same signals
are output.
the VOLUME control changes the amplitude of the signals output to the
headphones and OUTPUT 1. OUTPUT 2 and DIGITAL OUT have no volume
adjustment.
8. Effect check
The effect test is conduct on the built-in sound source.
Press a blinking button on the SD-80 to produce the sound effect. Check this

MFX
Press the [INST] button to send a snare sound at an interval of 2.5 seconds
from the power source. Make sure that a delayed sound is heard after the
original snare sound.
SYSTEM EFFECT (Delay)
Press the [EFFECTS] button to send a castanets sound at an interval of 2.5
seconds from the power source. Make sure that a delayed sound panning
right and left, is heard after the original castanets sound.
SYSTEM EFFECT (Reverb)
Press the [SYSTEM] button to send a snare sound at an interval of 2.5
seconds from the power source. Make sure that the snare sound
reverberates.
9. Factory reset
If all the test results are OK, initialize the system parameters as the last step.
Press the blinking [PREVIEW] button to start initialization. Initialization is
completed when the “Complete!” message appears.
Turn off the SD-80’s power to end the test mode.
