TEST MODE
Backing Up the User Data
All user data is deleted when Test mode is carried out.
Also be sure to reload the user data after competing Test mode.
Required Equipment
1. SP-404 SERVICE DATA & PROGRAM CD-ROM (#17041673)
2. Computer equipped with CD-ROM drive and CompactFlash reader/
writer
3. 2 memory cards (CompactFlash, minimum 32 MB capacity). In the
instructions that follow, these are referred to as the backup memory card
and test memory card.
4. MIDI Cable
5. Audio Cable
6. MIDI device (UM-1, MC-909, Fantom, V-Synth, or other MIDI device that
transmits Active Sensing)
7. MIC
8. Oscillator or similar device (for input of audio signals)
9. Oscilloscope, speakers (for confirming output audio signals)
Setup
First create a test memory card and insert it in the SP-404, connect all required
cables, then carry out the following preparations before entering Test mode.
Creating the Test Memory Card
The following tests cannot be performed without a test memory card.
• Memory Card Check (performed during the automatic checks)
• Demo Play
(Tests other than those listed above can be performed without a test memory
card.)
1. Format the test memory card with the SP-404 (refer to the instructions for
initializing the system).
2. Turn off the power to the SP-404, and eject the test memory card from the
SP-404.
3. Insert the test memory card in the computer’s CompactFlash reader/
writer.
4. Place the SP-404 SERVICE DATA CD-ROM in the computer’s CD-ROM
drive.
5. Copy the “\FCTRY” folder on the SP-404 SERVICE DATA CD-ROM
separately to the “\ROLAND” folder on the test memory card.
6. Eject the test memory card from the CompactFlash reader/writer.
7. Prepare to enter Test mode in reference to the following procedures.
Insert the memory card and connect the
cables.
1. Insert the test memory card in the memory card slot.
2. Connect a MIDI device that transmits Active Sensing (e.g., UM-1, MC-
909, Fantom, V-Synth, etc.) to MIDI IN.
3. Input an audio signal to LINE IN L/R with an oscillator or other such
device.
4. Enable the oscilloscope or similar device to measure signals from LINE
OUT L/R.
5. Connect a mic to the MIC jack.
6. Set the MIC LEVEL volume to maximum.
7. This completes preparations for Test mode.
Refer to “Entering Test Mode” and proceed with testing.
Entering Test Mode
1. Turn off the power to the SP-404.
2. Insert the test memory card in the memory card slot.
3. Simultaneously hold down [PITCH], [VINYL SIM], and [HOLD] and turn
on the power to the SP-404.
“tSt” appears in the display, and the SP-404 automatically begins Test
mode (with 1. Device Check).
* the Device check is completed without error, the display changes to “Lin.”
Exiting Test Mode
Turn off the power.
Selecting the Test Category
The following procedure can be used to select individual test categories during
Test mode.
Test Categories
Start Test mode. Refer to “Entering Test Mode.”
1. Device Check
“tSt” appears in the display, and all 11 categories are checked automatically.
If all tests are passed without error, the procedure automatically advances to
“2. Input/Output Jack Check.”
If any test fails, the corresponding item is indicated with the PAD LEDs (the
procedure does not automatically advance to the next test).
