[PRESET], [USER], [GM/XG], [7], [8], [9], [4], [5], [6], [1], [2], [3],
[0], [-], [ENTER], [EXIT]
If the following switches are operating normally, the LED will come
on and the unit will start emitting a sine-wave sound when you set the
switch to ON, and the LED and the sound will both go off when you
set the switch to OFF: [MULTI], [VOICE], [DEMO], [EDIT],
[CATEGORY SEARCH], [PRESET], [USER], [GM/XG].
For all other switches, the switch is normal if the unit emits a sine-
wave sound when you set the switch ON, and stops emitting the sound
when you set the switch OFF.
The unit will not respond if you press the wrong switch (a switch
other than the switch indicated on the LCD). When all switches have
passed the test, the LCD displays OK and the test terminates.
