3-3-9. KEY test
The key test is intended to check whether any key pressed is
recognized or not (AD misdetection check). When this test mode is
selected, the initial screen for key test displays the blinking characters
“KEY TEST”. By pressing the Bx key while the “KEY TEST”
characters are blinking, the characters “PLAY” will be displayed
entering the key test screen.
Once the key test is started, the test will not be completed until all
of keys are pressed. To exit from the key test mode, turn the power
off (remove the power cord). The key test includes the following
key tests:
