16: PC-CARD Test
fig.13-20_70
Check card slot operation.
• Insert a PC card into the PC card slot.
* Use a PC card (formatted by the V-Synth).
• Press [ ]. Write/Read tests will be performed. If they were
successful, the display will indicate "OK."
• If the test results were "OK," you will automatically proceed to the next
test item.
Problem
"OK" is not displayed
17: D-Beam Adjust
Adjust the D Beam.
* This adjustment sets the response range of the D Beam in a range of 40 cm to 10
cm from the chassis, allowing the D Beam to be controlled optimally.
fig.13-21_70
• First, position your hand 10 cm above the D Beam and press [
distance of 10 cm is approximately the width of four white keys.
• Next, position your hand 40 cm above the D Beam and press [
distance of 40 cm is approximately the width of seventeen white keys.
• If these two settings are not performed correctly, the NG screen will
appear. Press [ ] to return to the setting screen, and perform the
settings again.
• When the adjustment is completed, you will automatically proceed to
the next test item.

18: D-Beam Check
Check the results of the adjustment that was performed in item 17.
fig.13-22_70
• Position your hand above the D Beam, and raise or lower it in a range of
10 cm to 40 cm.
• "OK" results will be displayed if a maximum value reaches 127 (10 cm
above the D Beam) and the minimum value reaches 0 (40 cm above the D
Beam), and a confirmation tone will be output.
• If "OK" is displayed for both points, you will automatically proceed to
the next test item.
Problem
No response at all
Responds, but no "OK" result
19: Switch & LED TEST

• The LED will blink for approximately one second and then go dark.
• The switches will be shown in the screen as [@]. When a switch is
pressed, the [@] will change to [.].
