Display of current value of laser
(1) Set the main body at test mode.
(2) Press "CHOICE" 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 ("14" in "1419") shows current value of laser at the time of adjustment after the latest all-initialization,
14mA in this example.
• The last two numbers ("19" in "1419") shows the present current value of laser, 19mA in this example.
• The first two numbers ("14" in "1419") usually shows current value of laser at the time of shipment, so you can see how the
product has been deteriorated by comparing the first two numbers ("14" in "1419") and the last two numbers ("19" in "1419").
CD and DVD:
The laser current value of 80mA or less in normal. The laser current value of over 81mA is not normal. Laser
diode of the pickup has been deteriorated.
