Samplinq Option Test
This test is relevant only if the sampling option has been installed in the
unit under test. If no sampling board is present, this test will fail.
This test
is
only necessary when the sampling option has been installed.
The "five-step sampling option test" checks the integrity of the sampling
option board and its connections to the CPU. The five steps check the
following items:
1 Noise and distortion, clock test
2 Audio level overload test
3 Gain test
4 Input jack test
5 Digital
Ilo
test
If there is a failure in any of the five steps, the LCD will show a failure
for the entire test. In this case you should check the connections of the
sampling option board. When done, run the test again. If it fails again,
replace the sampling option board.
