TEST MODE

*The servo circuit of this model is regulated for no manual adjustment, and its IC controls the whole process internally.

This TEST MODE enables to monitor the adjustment status of each focus bias, tracking balance, tracking gain, and

focus gain in the IC.

1. Starting TEST MODE

1) Connect the AC plug.

2) While OPEN/CLOSE SW is set to ON, hold the PLAYMODE key and short a*test land for one second.

3) Check that all LCD light up while the *test land is on short. This indicates that TEST MODE is started.

MEMO:

1. During TEST MODE, the OPEN/CLOSE SW function is ignored, and it is not necessary to set the SW to ON for

operation.

2. Make sure that when aheadphone jack is not plugged. TEST MODE cannot be started.

2. Focus search mode

This mode enables to check the operation of focus search.

Starting the mode: Press the STOP button to start the mode when at stop mode status. To finish the mode, press the

STOP button again.

During this mode, adisc on the tray does not play (servo is not activated), and only search operation

is repeated.

3. Checking focus bias, tracking balance, focus gain, and tracking gain

While adisc is playing, press the PLAYMODE key to switch achecking mode to focus bias, tracking balance, focus

gain, or tracking gain. The mode is switched as the following order

Checking ~de OFF+ focus bias+ tracking balance+ focus Itracking gain 1

Focus bias

At the focus-bias checking mode, the LCD displaysthe diagram as shown below so that the bias setting level in the IC

can be monitored.

2Manual operation of focus bias control

At the f~cus-bias checking mode, press the F. SKIP key or B. SKIP key to set the focus bias manually.

The setting range is -00 to FOin 32 steps.

Check the RF wave shape with oscilloscope to adjust manually. Check that the initial value of RF signal level is

pointed at maximum. This indicates that the automatic adjustment is functioning properly.
