Test 23
Function:  Switch, LED Check
Description:
When a panel switch is being pressed, a sound is kept 
produced at a pitch corresponding to the switch (page 112).
When the switch is released, the sound is stopped.
If there is an LED for the switch, the LED will light up. 
The LED will be turned off when the next switch is pressed 
correctly.
In case of two-colored LED, both the two colors will light.
Operate the [DATA ENTRY] dial following the indications 
on the LCD to check Dial Up and Dial Down. (The number 
should increase when turned clockwise and decrease when 
turned counterclockwise.)
