4.6 Display of current value of laser
(1) Set the main body at test mode.
(2) Press "SET UP" key of the remote controller three times. Then, FL display is displayed "CHECK".
(3) The laser current value can be switched between the value of CD and that of DVD by pressing the following key of the remote
controller.
The number shown in the FL display shows mA of current value of laser.
The first two numbers ("25" in "2530") shows current value of laser at the time of adjustment after the latest all-initialization, 25mA
in this example.
The last two numbers ("30" in "2530") shows the present current value of laser, 30mA in this example.
The first two numbers ("25" in "2530") usually shows current value of laser at the time of shipment, so you can see how the prod-
uct has been deteriorated by comparing the first two numbers ("25" in "2530") and the last two numbers ("30" in "2530").
CD:
The laser current value of 49 mA or less is normal.The laser current value of over 50 mA is not normal. Laser diode of the
pickup has been deteriorated.
DVD:
The laser current value of 64 mA or less is normal.The laser current value of over 65 mA is not normal. Laser diode of the
pickup has been deteriorated.
To return to test mode, press "STOP" key of the main body.
