SECTION 4
TEST MODE
Outline
• In this set, overall adjustment mode is made available by enter-
ing test mode to perform automatic adjustment of CD and MO.
In the overall adjustment mode, the disc is determined whether
it is CD or MO and adjustments are performed in sequence. If a
fault is found, the location of the fault is displayed.Also, in servo
mode, each adjustment can be automatically made.
• Operation in the test mode is performed with the Remote Com-
mander. A key having no particular description in the text, indi-
cates a Remote Commander key.
Setting theTest Mode
To enter the test mode, two methods are available :
1. Entering method with key input.
Turn on the HOLD switch on the set. While holding down the x
key on the set, press the following remote commander keys in
the following order :
B/>tB/>t.t.tB/>t.t
B/>t.tXtX
2. Entering method by shorting the test point
Solder bridge the test point TAP805 (TEST) on the main board
(connect IC801 pin ed to GND), and turn on the POWER.
[MAIN BOARD] (SIDE B)
Releasing theTest Mode
1. When test mode was entered with key input, turn offthePOWER.
2. When test mode was entered by shorting the test point, turn off
the POWER and open the solder bridge of TAP805 (TEST
MODE) on the main board.
Operation of Setting onTest Mode
When the test mode is set, the LCD displays the following :
• The cycle - the above ROM version display tAll lit tAll off
- is repeated.
(The ROM version is constantly displayed.)
• When the PLAY MODE key is pressed and hold down, the dis-
play at that time is held so that display can be checked.
Configuration ofTest Mode
The test mode has the configuration given below.
Servo Mode
• Set the test mode, press theVOLUME – key and use the B/>
key to set the servo mode.
• When the servo mode is set, use the B/>key and the .
key to move the optical pick-up to the outer circumference and
to the inner circumference respectively.
• When entering another mode, refer to the configuration of test
mode.
