WARNING :
Static discharges can destroy expensive components. Discharge any static electricity your body may have
accumulated by grounding yourself to the ground bus in the unit (heavy gauge black wires connect to
this bus.)
IMPORTANT :
Turn the unit OFF during disassembly and parts replacement. Recheck all work before you apply power
to the unit.
LITHIUM BATTERY HANDLING
This product uses a lithium battery for memory back-up.
WARNING :
Lithium batteries are dangerous because they can be exploded by improper handling. Observe the following precautions when handling or replacing lithium batteries.
Leave lithium battery replacement to qualified service personnel.
Always replace with batteries of the same type.
When installing on the PC board by soldering, solder using the connection terminals provided on the battery cells.
Never solder directly to the cells. Perform the soldering as quickly as possible.
Never reverse the battery polarities when installing.
Do not short the batteries.
Do not attempt to recharge these batteries.
Do not disasemble the batteries.
Never heat batteries or throw them into fire.
ADVARSEL!
Lithiumbatteri-Eksplosionsfare ved fejlagtig handtering. Udskiftning ma kun ske med batteri af samme fabrikat og type. lever det brugte
batteri tilbage til leverandren.
VARNING
Explosionsfara vid felaktigt batteribyte.
Anvand samma batterityp eller en ekvivalent typ som rekommenderas av apparattillverkaren.
Kassera anvant batteri enligt fabrikantens instruktion.
VAROITUS
Paristo voi rajahtaa, jos se on virheellisesti asennettu.
Vaihda paristo ainoastaan laitevalmistajan suosittelemaan tyyppiiin.
Havita kaytetty paristo valmistajan ohjeiden mukaisesti.
The following information complies with Dutch official Gazette 1995. 45; ESSENTIALS OF ORDER ON THE COLLECTION OF BATTERIES.
• Please refer to the diassembly procedure for the removal of Back-up Battery.
• Leest u voor het verwijderen van de backup batterij deze beschrijving.
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
originally installed.

B. TEST PROGRAM
0: LED Check
1: SW Check
2: VR Check
3: Battery Check
4: MIDI Check
5: SRAM Check
6: DSP Check
C. STARTING THE TEST PROGRAM
While pressing the MANUAL, STORE and HALL switches,
turn on the POWER switch. The TEST program will then
be started.
D. SELECTING THE TEST NUMBER
Using the UP and DOWN switches, select the test number
and press the STORE switch to confirm selection.
E. TEST PROCEDURE
0: LED Check
• Using the UP and DOWN switches, select “0” and
then press the STORE switch.
• LED segments light up one after another starting with
“UP”. When “SP.SIM” is reached, “BANK”, “3”, “2” and
“1” light up followed by 7 segments in the following
order from the left end. After that, all LED segments
light up and go out.

1:
SW Check
• Using the UP and DOWN switches, select “1” and
then press the STORE switch.
• Starting with the UP switch, press the switches whose
LED lights up one after another. After “SP.SIM”, “BANK”,
“3”, “2” and “1”, all LED segments should light up and
then go out.
• Numbers (0 to 20) are indicated at the right end of the
7 segment LED.
• If “E” representing an error appears at the left end,
press the UTILITY switch for resetting.
2:
VR Check
• Using the UP and DOWN switches, select “2” and
then press the STORE switch.
• Execute checking with “AMP SELECT” and “GAIN” to
“PRESENCE” in that order, next from “COMP” to
“REVERB” and finally until “EXP. PEDAL”
• Turn the control fully in the direction toward the left 7
segment LED which is turned on. If the test result is
OK, the right 7 segment LED lights up. Then turn the
control to that direction. If the test result is OK, proceed
to the next VR. After completing this check, return the
control to the center position.
• If an error exists outside of the control being checked,
“E” meaning an error appears at the left end. In such
case, press the UTILITY switch for resetting.
• At the end of all VR checks, all LED segments light up
and go out.
3:
Battery Check
• Using the UP and DOWN switches, select “3” and
then press the STORE switch.
• If the check result is OK, all LED segments light up
and go out.
• “E” appears in case of an error.
4:
MIDI Check
• Using the UP and DOWN switches, select “4” and
then press the STORE switch.
• If the check result is OK, all LED segments light up
and go out. Then checking advances to the next step.
• In case of an error, “E” is indicated by LED.
• The numeric figure at the right end of LEF represents,
0: transmission and 1: reception.
5:
SRAM Check
• Using the UP and DOWN switches, select “5” and
then press the STORE switch.
• If the check result is OK, all LED segments light up
and go out.
• “0” and “1” at the right end represent IC2 and IC3
respectively.

DG-Stomp
6: DSP Electric Characteristic
• Using the UP and DOWN switches, select “6” and
then press the STORE switch.The output level becomes
the same when the right end No. is “0” and when it is “1”.
• The output level, noise level and distortion rate can
be checked by inputting the signal for measurement
(by shorting the input with GND for the noise level check).
• Initial setting: HIGH/LOW SW (SW101) ••• OFF
(LOW), VR ••• Center, OUTPUT VR ••• MAX

HOW TO CONFRIM ROM VERSION
Turn on the power while pressing “DOWN” and “MANUAL
SW” switches, and the model name appears as dG.S
for about 2 seconds and then the version number as *.**
also for about 2 seconds. (Each * represents a numeric
figure.) Read that number for confirmation. The normal
mode will then be resumed.

ERROR MESSAGES
If an error occurs during operation, one of the following error message numbers will appear on the display.
E1: MIDI Receive Buffer Full
CAUSE:
Too much MIDI data is being received by the DG amplifier at one time.
SOLUTION: Try reducing the amount of data being sent or, break the data into smaller blocks.
E2: Communication Error.
CAUSE:
An abnormality is detected during MIDI communications.
SOLUTION: Check all connections, etc. and try again.
E3: Bulk Receive Check Sum Error.
CAUSE:
The check sum does not match the received MIDI bulk data.
SOLUTION: Check all connections and data, and try again.
E4: Bulk Receive Data Abnormality.
CAUSE:
An abnormality is detected in the received MIDI bulk data.
SOLUTION: Check all connections and data, and try again.
E5: Backup Battery Error.
CAUSE:
Backup battery power is depleted.
SOLUTION: Continued use of the device will result in the loss of data. Return the device to the music
dealer where you purchased it or, have the battery replaced.
