The test menu operation method - 1

MB-S1

1. Change unit into a standby mode.

2. Push the DISPLAY key and the STOP key simultaneously.

-> It is displayed on FL tube as "TEST MODE", and will be in an all-points light state in about 1 second (test mode level 1 state).

3. Push the CD key and the HDD key.

-> It is displayed on FL tube as "SYSTEM INIT."

It shifts to test mode level 2 state above.

When menus, such as "SYSTEM INIT", are displayed, the DISPLAY key and the STOP key are pushed simultaneously.

-> It is displayed as "NORMAL MODE" and returns to a

standby state.

SYSTEM INIT: Initialization of a flash ROM and initialization of HDD are

performed. DOWNLOAD START: It shifts to the software rewriting mode of a main program. FLASH REBUILD: The information currently recorded on HDD is reconstructed on

a flash ROM. KEY FUNCTION: A key function is displayed (with no necessity of using it at the

time of a maintenance). VERSION: The version of each program is displayed. The above-mentioned menu is displayed by turning JOG after test mode shift. The selected function is performed when JOG is pushed.

[Method]

1. Choose a menu as "SYSTEM INIT" and push JOG.

2. The message of a check is displayed on FL pipe as "Really?."

Please push the YES key, when you perform. Please push the

NO key, when you cancel.

3. It is automatic in order of "flash initialization ->HDD

initialization",

4. "INIT COMPLETE! If "is displayed, it will be completion of

operation. [Notes]

- if this function is performed, the music data currently recorded

on all HDD and the inputted tag data will be disappeared and

lost. Be fully careful of handling.

- When HDD is exchanged for a new one, please be sure to

perform initialization of HDD and a flash ROM using this

function. An incorrect operation will be caused if equipment is used

without performing this function.

- When the power supply of equipment falls by a certain reason

while performing this function, please perform again. An incorrect operation will be caused if equipment is used in the

state where it is initialized halfway. [The use pattern assumed]

- When HDD is exchanged

[Methode]

1. Choose a menu as "DOWNLOAD START" and push JOG.

2. The message of a check is displayed on FL pipe as "Really?." Please push the YES key, when you perform. Please push the NO key, when you cancel.

3. The display of FL tube disappears and the CD button and the HDD button of equipment light up after a while.

4. Connect a USB cable between unit and PC and download by

starting farm download software (bluefire). [Notes]

- It becomes impossible to use unit, once it performs this function until it next finishes writing in software.

Since it does not usually return to processing even if it takes out

and inserts AC plug, be careful of handling enough.

- Before the CD button and the HDD button light up, even if it starts farm download software (bluefire), an error is displayed and software may not start.

Please restart software again after waiting to switch on the light.

[Methode]

1. Choose a menu as "FLASH REBUILD" and push JOG.

2. The message of a check is displayed on FL pipe as "Really?." Please push the YES key, when you perform. Please push the NO key, when you cancel.

3. Flash ROM initialization -> perform data reconstruction processing automatically.

4. "REBUILD OK! If "is displayed, it will be completion of

operation. [Notes]

- If this function is performed, since it is unrestorable, please understand beforehand the tag information inputted into the music data currently recorded in PCM form among the tag information inputted

(Since the domain which stores tag information does not exist in

the PCM file currently recorded on HDD on the relation of a file system)

- When the power supply of equipment falls by a certain reason while performing this function, please perform again.

An incorrect operation will be caused if equipment is used in the

state where it is reconstructed halfway.

- When the music data currently recorded on HDD exists in large quantities, this thing has time in processing.

- Please do not perform this function to HDD which has not performed SYSTEM INIT processing once.

It is in the middle of of operation, and may hang-up. [The use pattern assumed]

- When substrate exchange is performed

The test menu operation method - 2

[Real whereabouts method]

1. Combine a menu with "VERSION" and push JOG.

2. The version of each farm is displayed. A display can be changed by turning JOG.

The contents displayed are as follows.

- Main ....

Soft version number currently recorded on the external flash

ROM (whole charge of operation)

- Boot ....

Soft version number currently recorded in CPU (V850) of a

main board (starting processing charge)

- Disp ....

Soft version number currently recorded on CPU of a display

board (display processing charge)

- USB ....

Soft version number currently recorded in CPU (MB89) of a

main board (USB communication charge)

- The soft version number currently recorded on the QP-B....

QPICT board (device control charge) Please push the MENU/EXIT key, when you escape from this mode. [Notes]

- When you check the version of QPICT software (QP-B), please reboot unit.

Please perform this function again and check a version, after

performing "POWER ON-> standby state ->OFF."
