(4) Display of current value of laser

(5) Display of jitter value

1)Makes to test mode and initializes
2)When "CHOICE" button of remote controller is pushed twice, It is displayed on the FL display, "CHECK".
3)The automatic adjustment starts when test disk (VT-501) is inserted, and "PAUSE" button of the main body
is pushed.
4)When the display of the FL display changes into "CHECK OK", the "PLAY" button of the main body is pushed.
5)The jitter value is displayed on the FL display as follows.

LD_0042

FL Display

JIT_3978

FL Display

As for the current value of the laser, the figure displayed on the
FL display becomes a current value as it is by "mA" unit.
becomes 42mA if displayed as 42.

If the laser current value is 64mA or less, it is roughly good. There is a possibility to which pick-up is
deteriorated, and exchange pick-up, please when there are 65mA or more laser current value.

If the indication value is 11% or less, it can be judged by this simple checking method that the signal
read precision of the set is satisfactory.
Please do "Flap adjustment of the pick-up guide shaft" when you replace the pick-up and the spindle
motor when there are 11% or more jitter value.

The jitter value is displayed by the hexadecimal number and refer
to the conversion table of following, please.

1)Makes to test mode and initializes
2)When "CHOICE" button of remote controller is pushed twice, It is displayed on the FL display, "CHECK".
3)The display of FL display changes from "CHECK" into "LD_ON" if the "TITLE" button of remote controller
is pushed.
4)The laser is turned on if the "BACK SKIP" button ( ) of remote controller is pushed in the state,
and the current value of the laser is displayed on the FL display.

5)The laser changes from CD into DVD if 3) and 4) of the above-mentioned procedures are done after
the tray is opened and closed pushing the "OPEN/CLOSE" button of the main body.
(The laser changes whenever this is done.)
