2. CD Test Mode (TEST 1)
In the CD test mode the operation of each step is possible even if the LID-SW is off. If focus cannot be taken in step 3 or any error
is processed, it is impossible to proceed to the next step. During error processing, end the test mode by pressing the ON/STAND-
BY button or return to the step 1 by pressing the CD STOP button. Any other operations are inhibited.
1. Step 1 Mode
When the CD test mode is obtained, the following display lights up. Then CD initialization operation flow proceeds up to CD
STB off to wait for the following buttons to be pressed.
One second after display lights up
Press the following buttons in this state to obtain the operations specified below.
"POWER" ................. Test mode and power turned off to shift to the ordinary standby mode.
"FF/FWD" ................. After the pickup returns to the innermost periphery, it slides toward the outer periphery while this button
is pressed.
"REW/REV" .............. After the pickup returns to the innermost periphery, it slides toward the inner periphery while this button
is pressed. If PICKUP IN is on, input is invalid.
"PLAY" ..................... Shift to step 2
"STOP" ..................... Invalid
"FUNCTION" ............ Shift to step 5
* In case of initialization, the pickup is moved toward the inner periphery. Any buttons other than "ON/STAND-BY" button are
not accepted until the shift of pickup to the inner periphery is completed at this time. If PICKUP IN SW ON cannot be detected
within 10 seconds, the slide motor stops, and the following error display appears. Press the ON/STAND-BY button to end
the test mode, or press the CD STOP button to return to step 1. Any other operations are inhibited.
The test mode applied to this microcomputer has three modes, namely the ordinary test mode for adjustment or measurement,
the aging test mode, and the self-diagnosis test mode for self-judgment in case of final product inspection.
1. Turning on the test mode
For obtaining each test mode, press the ON/STAND-BY button, while keeping pressing the following two buttons in the ordinary
stand-by mode (power off ). In this case, the main unit buttons are valid. When turning the ON/STAND-BY on with remote control
buttons, test modes are not obtained.
