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 and must be replaced with parts having specification equal to those originally installed.

C. STARTING THE TEST PROGRAM AND CHECKING

While pressing the MANUAL, STORE and ROOM switches, turn on the POWER switch. The TEST program will then be started. At this time, check to mak e sure that the model name “AG.S” is displa y ed f or about 2 seconds. The digit at the left end of the 7-segment LED indicates the test No.

D. SELECTING THE TEST NUMBER

• Using the UP and DOWN switches, select the test

number and press the STORE s witch to start testing.

E.

OPERA TION OF THE TEST PROGRAM AND CHECKING 0: LED check

(1) Using the UP and DOWN switches, select “0”. (This step can be skipped if “0” is already selected.) (2) Press the STORE switch.

• LED segments light up one after another starting with “UP”. When “MIC” is reached, “BANK”, “1”, “2” and “3” light up followed by 7 segments in the following order from the left end. After that, all LED segments light up and go out.(Fig.1)

(1) Using the UP and DOWN switches, select “1”. (This step can be skipped if “1” is already selected.) (2) Press the STORE switch. (3) Starting with the UP switch, press each switch whose

LED lights up one after another. After “MIC”, “BANK”, “3”, “2” and “1”, all LED segments should light up and then go out.

• A number (0 to 20) is indicated at the right end of the 7 segment LED.

• If “E” representing an error appears at the left end of the LED , press the UTILITY switch for resetting.

2: VR Check (Be sure to set each of VR, SW and EXP

PEDAL to be checked at its center position.)

(1) Using the UP and DOWN switches, select “2”.

• All LED segments light up and go out, and then the checking proceeds to MIDI check.

• If VR, SW or EXP PEDAL is not set at its center position, checking will result in an error and E. 0 will appear at the left end of LED. In such case, set it to the center position and press UTILITY SW for resetting.

• To advance the VR No . to be checked, press MANUAL SW.

3: MIDI Check

(1) Using the UP and DOWN switches, select “3”. (This step can be skipped if “3” is already selected.) (2) Press the STORE switch.

• If the check result is OK, all LED segments light up and go out. The checking function will proceed to the next step.

• In case of an error, “E” appears at the left end of the LED. “0” at the right end indicates transmission and “1” indicates reception.

4: SRAM Check

(1) Using the UP and DOWN switches, select “4”. (This step can be skipped if “4” is already selected.) (2) Press the STORE switch.

• If the check result is OK, all LED segments light up and go out. The checking function will proceed to the next step.

• In case of an error, “E” appears at the left end of the LED . “0” at the right end indicates IC2 and “1” indicates IC3.

5. FLASH ROM Check

(1) Using the UP and DOWN switches, select “5”. (This step can be skipped if “5” is already selected.) (2) Press the STORE switch.

• If the check result is OK, all LED segments light up and go out. The checking function will proceed to the next step.

• In case of an error, “E” appears at the left end of the LED. “0” at the right end indicates “1 sector erase”, “1” indicates “Er ase check” and “2” indicates “Write check”.

6: DSP Electric Characteristic

(1) Using the UP and DOWN switches, select “6”. (This step can be skipped if “6” is already selected.) (2) Press the STORE switch.

• An input signal will be output when the STORE switch is pressed. “0” appears at the right end of the LED. (Table.1)

• The sine wavef orm can be checked in all of the analog circuit, AD, DSP-6 and D/A where the signal has passed.

ERROR MESSAGES

If an error occurs during operation, one of the following error message numbers will appear in the display. Stop operation of the AG-Stomp and follow one of the solutions described below.

E1: MIDI Receive Buffer Full

CAUSE: Too much MIDI data is being received and the buffer is full 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 dump data. SOLUTION:Check all connections and transmitted data, and try again.

E4: Bulk Receive Data Abnormality.

CAUSE: An abnormality is detected while receiving the bulk dump. SOLUTION:Check all connections and transmitted data, and try again.
