be performed by an authorizedYamaha Retailer or the appointed service representative.

IMPORTANT : This presentation or sale of this manual to any individual or firm does not constitute authorization,

certification, recognition of any applicable technical capabilities, or establish a principal-agent

relationship of any form.

The data provided is believed to be accurate and applicable to the unit (s) indicated on the cover.The research engineering,

and service departments of Yamaha are continually striving to improveYamaha products. Modifications are, therefore,

inevitable and changes in specification are subject to change without notice or obligation to retrofit.Should any discrepancy

IMPORTANT : Turn the unit OFF during disassembly and parts replacement. Recheck all work before you apply

power to the unit.

WARNING : CHEMICAL CONTENT NOTICE !

The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/or plastic

(where applicable) components may also contain traces of chemicals found by the California Health and Welfare Agency

(and possibly other entities) to cause cancer and/or birth defects or other reproductive harm.

DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY

REASON WHAT SO EVER!

Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose

eyes to solder/flux vapor!

If you come in contact with solder or components located inside the enclosure of this product, wash your hands before

handling food.

■WARNING

Components having special characteristics are marked Zand must be replaced with parts having specification equal to

those originally installed.

Z印の部品は、安全を維持するために重要な部品です。交換する場合は、安全のために必ず指定の部品をご使用ください。

■SAVING DATA

• Never attempt to turn off the power while data is being

written to Flash ROM (while a "now storing..." message

is shown).Turning the power off in this state results in

loss of all user data and may cause the system to freeze

(due to corruption of data in the Flash ROM).This means

that this instrument may not be able to start up properly,

even when turning the power on next time.

DTXPRESS

A. Test entry

While pressing the [DRUM KIT] and [SAVE/ENTER] keys

simultaneously, turn on the power to the DTXPRESS .

DIAG att cr xt

677f 2450 04

The value on the lower level on the screen indicates the limit

value of the trigger input level test of Test items C-11 to 22.

If no change is made to the limit value, press the [SAVE/ENTER]

key, and the LCD indication changes to [Test number select

screen].

If any change is made to the limit value, select the parameter

you want to change by using [PAGE ] and [PAGE ] and make

the setting by using the rotary encoder.

Details of each parameter are as described below.

* The range of all parameters is 00 to ff.

* When the parameter is set at the upper limit or lower limit in

the range, that value is included in the OK range.

67: Lower limit of the input signal level OK range of

INPUT qSNARE–iKICK/9

7f: Upper limit of the input signal level OK range of

INPUT qSNARE–iKICK/9

24: Lower limit of the time constant value OK range of

INPUT qSNARE–iKICK/9

50: Upper limit of the time constant value OK range of

INPUT qSNARE–iKICK/9

04: Upper limit of the crosstalk value OK range of INPUT

qSNARE–iKICK/9

After changing all parameters, press the [SAVE/ENTER] key,

and the screen changes to [Test number select screen].

B. Carrying on the test (when the test result

is FAIL as well)

When the test entry procedure is completed, the following

appears.

DIAG att cr xt

677f 2450 04

Press the [SAVE/ENTER] key, and the following appears.

1 ROM

This screen state is called [Test number select screen].

Select the test number by using [PAGE ] and [PAGE ] and

press the [SAVE/ENTER] key, and selected tests are executed

in the order of the test number automatically,

If any failure occurs, FAIL appears on the screen and testing

stops.

How to carry on the test when the test result is FAIL

When the test is judged as FAIL, press the [SHIFT] key, and

[A0 XX 03] (XX represents each test code) is output from MIDI

OUT and the screen changes to the [Test number select screen].

C. Test item

Listed below are contents of tests from C-01 to C-35.

(See page 18)

C-01. ROM

[Test code]

[Initial indication]

1 ROM

[Test content]

Read the P2ROM data and verify it.

[Test method]

Press the [SAVE/ENTER] key to execute the test.

[Check item]

Check the LCD test result.

(When the result is OK, testing proceeds to the next test and so

it is not possible to check the result by LCD indication.)

[Indication of judgment result]

When the result is OK

C-02. FLASH test is started automatically.

When the result is NG (example)

1 ROM

FAIL 9110

[Content of FAIL judgment]

None

[MIDI code output of judgment result]

OK A0 01 02

FAIL A0 01 03

[Completing the test]

When the result is OK, testing proceeds to the next test.

For the procedure when the test is judged as FAIL before its

completion, refer to "B. Carrying on the test"

C-02. FLASH

[Test code]

[Initial indication]

2 FLASH

[Test content]

Check the manufacture code and device ID of FLASH ROM.

[Test method]

Press the [SAVE/ENTER] key to execute the test.

Execute C-01. ROM test and if its result is OK, the test is started

automatically.

[Check item]

Check the LCD test result.

(When the result is OK, testing proceeds to the next test and so

it is not possible to check the result by LCD indication.)

[Indication of judgment result]

When the result is OK

C-03. SRAM test is started automatically.

When the result is NG

2 FLASH

FAIL

[Content of FAIL judgment]

None

[MIDI code output of judgment result]

OK A0 02 02

FAIL A0 02 03

[Completing the test]

When the result is OK, testing proceeds to the next test.

For the procedure when the test is judged as FAIL before its

completion, refer to "B. Carrying on the test"
