Method of displaying region code

(1) Set the main body at test mode. 
(2) Press "MENU" key of the remote controller three times. Then, region code are displayed in the FL display.

4.4

Initialization method

Please initialize according to the following procedures in the following case:
• Just after you upgrade the firmware.
• After you confirm the symptoms that a customer points out. First Initialize, and then confirm whether the symptoms are improved or

not.

• After servicing, before returning the main body to a customer. (Initialized main body should be returned to a customer.)

(1) Set the main body at test mode.
(2) Press "PAUSE" key of the main body.
(3) When initialization is completed, "00" and "RDS" is displayed in the FL display.

4.5

Display of current value of laser

(1) Set the main body at test mode. 
(2) Press "MENU" key of the remote controller five 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.

• To return to test mode, press "STOP" key of the main body.
