2. RAM Check
Upon entering the test mode, the program automatically
starts RAM checking. When the test is successful, the
program proceeds to the next step. Otherwise it shows
an error message on the 7-SEG LED as shown in Fig.2,
and won't proceed to the next step. Pressing INC while in
the error forces the program to jump to test 5. Switch and
LED check.

5. Switch and LED Check
All LEDs turn on. Press the buttons one by one and the
corresponding LED will turn off associated with apiano
tone. For checking the 7-SEG LED, press INC and the
upper segments will turn off; next, press DEC and the
lower segments turn off.
Simultaneous pressing of INC and TRANSPOSE goes to
the next test.
6. A/D Check
(a) Slider Check
Move LOWER slider from minimum to maximum
position. The 7-SEG LED will show the name of the
slider being operated, as shown in Fig. 6. The number
of lighting LEDs of the 11 LEDs shown in Fig. 5will
increase as the slider travels. When the maximum
level is reached avibraphone tone sounds. Repeat
the step for the UPPER and VALUE sliders.
