6.2.2 Mode for checking load on the JOG dial and Adjustment

This mode is for objectively judging the load (light or heavy touch) on the JOG dial when it is turned, with a value.

[Measuring procedure]

After entering this mode, rapidly turn the JOG dial, either clockwise or counterclockwise. The figures will be displayed.

If, for example, "8.6: 115" is displayed, each figure means the following:

8.6 : Maximum speed (Normal speed is one rotation in 1.8 sec.) 115 : Time (in msec) required for decreasing the rotation speed

from 3 times to 1.5 times normal speed

To measure the time required for reducing the rotation speed, the maximum speed must be 7.0 times normal speed or higher.

If measurements are consecutively performed several times, the mean value of the results of up to four latest measurements will be displayed, in order to minimize variation.

Standard value: 95 ± 25 msec [Adjustment procedure]

1. Enter this mode.

2. Adjust the adjustment value of Adjust plate to "0".

3. Rapidly turn the JOG dial, either clockwise or counterclockwise.

4. The rotational speed (maximum speed) and time are displayed in the dot FL display section.

• The time required so that the rotation may decrease from 3 times normal speed to 1.5 times normal speed when maximum speed is only 7 times normal speed or more is displayed.

• Moreover, the mean value of the measurement result at the rotation decrease time is displayed since the second times.

• The thing that the mean value at the decrease of the rotation three times in total time is in the standard value (95 ± 25 msec) is confirmed. Perform the following procedure if coming off from the standard value.

5. When the rotational speed is smaller than 70, the adjustment value of the adjust plate is changed to "-1" and performs the procedure 3 and 4. (1)

When the rotational speed is larger than 120, the adjustment value of the adjust plate is changed to "+1" and performs the procedure 3 and 4. (2)

6.2.5 List of Error Codes/Detail Display mode

If an error is generated during Normal mode, one of the following error codes is displayed on the FL display.

Detailed error content (error described in the Error content column of the table below: E-XX) can be confirmed if the JOG MODE key is pressed during Software Version Check mode for the Player microcomputer.

Each time the JOG MODE key is pressed, the version number and error display are cyclically displayed.

The first error displayed when the JOG MODE key is pressed is the latest, and each time the LOOP DIVIDE − key is pressed the previous error is displayed (pressing the LOOP DIVIDE + key displays the oldest error). Data for up to 16 errors are stored in memory.

For errors E-12 and E-15, the address (TNO:MIN:SEC:FRM) where an error was generated is also stored in memory, and it can be displayed by pressing the TIME MODE key (toggle operation).

∗ If these errors are generated before the loaded disc is identified as a CD, the disc is automatically ejected. In this case, the error code is not displayed, but you can check it, as the error content is stored in memory.

∗∗ Data for errors E-6002, E-8304, E-8305 and E-8709 are not stored in the memory.

To clear error logs, turn on the power while simultaneously holding the BACK and USB keys pressed.

In this case, the following settings are reset to the initial settings:

Note: A function for storing the CUE/LOOP point in memory is provided with this unit.

Play (trace)/Pause

If this command is issued in Stop mode, the unit is set up and starts playing. If the command is issued in Playback mode, pause and playback are alternately performed each time the PLAY/PAUSE key is pressed. The address currently being played back is displayed on the FL display.

Note: In this mode, auto setup is not performed when a disc is inserted. Playback in this mode does not mean audio playback but trace of the signal area on a disc. In playback, tracing is performed at four the speed of normal playback.

No audio signal is output.

6.2.6 Operation Check mode for the Player section

Player Operation mode: ON

Player Operation mode: CANCEL

This mode consists of Player Operation mode and Test Operation mode.

Player Operation mode

In this mode, basic operations of the servomechanism, such as setup, playback, pause, and track search, are checked.

Error rates can also be measured.

Test Operation mode

Servo operations can be controlled step by step in detail.

Notes:

• Switching from Player Operation mode to Test Operation mode can be accomplished by pressing the MASTER TEMPO key.

• Commands in Test Operation mode are mainly for testing the mechanism and servomechanism, not for testing the DJ functions, such as scan and tempo.

Track Search F/R

The unit starts searching for the displayed track in the forward or reverse direction and will pause when it finds it.

Error Rate Count

An error rate is measured from the current Play/Pause position for about 10 seconds (duration of disc recording).

The result will be displayed on the FL display. Normally, search for the track to be measured then press the CUE key in Pause mode. The error rate is displayed, for example, as "3.56E-4 OK." "OK" is displayed if the error rate is 3.00E-3 or less, and "NG" is displayed if it is more than 3.00E-3. The result is determined on the assumption that the measurement is performed using a control disc upon shipmentof the product. This measurement cannot be used for judging whether or not the product is defective during servicing.

Eject

The loaded disc is ejected.

Mode Change

Press the MASTER TEMPO key during Player Operation mode to change to Test Operation mode. The MASTER TEMPO LED lights up, and Test Operation mode (described below) is entered.

• Test Operation mode

Servo operations can be controlled step by step in detail.

Please note that incorrect use of commands in Test Operation mode may damage the player.

Servo All Off

When the TIME key is pressed during Servo ON, all the servos will be shut off. "ALL OFF" is displayed.

LD On/Off

Pressing the TEMPO key turns the LD ON or OFF. "LD ON" or "LD OFF" is displayed.
