(5) Press "3D-PHONIC" button of remote controller. and EEPROM initialize start.
(6) When indicate "DTS" on the display, initialize finishes.
(7) The power is turned OFF, and Unplug the power plug.
3.2 Display of "Laser current value" and "Jitter value"
"Laser current value" and "Jitter value" are displayed on the FL display by the undermentioned
method. Please refer to the failure diagnosis.
(1) Take out the disc and close the tray.
(2) Unplug the power plug.
(3) Insert power plug into outlet while pressing both "PLAY" button and "OPEN/CLOSE" button.

The laser current value becomes 40mA for the above-mentioned.
Becomes a test mode by doing above-mentioned procedure 1) - 4). Afterwards, the laser current value can
be switched by pushing the button to remote controller without turning on the disk.
It can be judged it is simply good if the displayed current value of the laser is smaller than that of the undermentioned value.
Moreover, there must be a deteriorated possibility and the pick-up must exchange the pick-up more than the undermen-
tioned value.
Laser current value of CD ------ 49 mA or less
Laser current value of DVD ---- 64 mA or less
