Detailed Test Items
1.
1.
Connect standard audio (mono) cables to all of the INPUT A(MONO)
and B jacks and OUTPUT A(MONO) and B jacks, and connect a stereo/
monaural converter cable (PCS-31 or similar) to the CTL jack. Connect the
other ends to the two FS-5U foot switches, and set the “POLARITY”
switch on the FS-5Us towards the FS-5U jacks.
2.
Turn all volume controls completely to the left (to minimum).
3.
While holding down the left pedal’s ON/OFF and the right pedal’s TAP/
MEMORY, connect the +9V DC plug to the ADAPTOR jack (which turns
on the power).
DSP, EEPROM Check (also used to indicate the version)
•

•
After the unit is switched to Test mode, the version number
automatically appears in the LCD as a four-digit number, while
simultaneously the DSP and EEPROM check is performed.
•
Confirm that all of the LEDs are lit, indicating that no problem was
detected.
If there is a problem, the cause is indicated by the LEDs as described below.
ON/OFF flashing:EEPROM error
MEMORY flashing:DSP PRAM error

ON/OFF, TAP flashing:DSP DRQ error
LCD, Switch, LED Checks, Foot Switch Operational Check
Press the [TAP] switch. Confirm that the LCD’s “8.8.8.8” lights up and go off in
the sequence shown below.
In “2”, if no +9V DC plug is connected to the ADAPTOR jack, the power can
be turned on by inserting batteries in the unit and connecting the INPUT
A(MONO) plug.
The “DSP, EEPROM Check” commences automatically with entry into Test
mode.
The status of the LEDs differs when entering into Test mode. For more detailed
information, refer to the item “DSP, EEPROM Check.”
The unit cannot enter Test mode unless all of the volume controls are turned to
minimum (MODE: “SOS”).
To conduct only a specific test, after entering Test mode, switch the MODE
volume control to the setting corresponding to the desired test.
Although carrying out the procedure in “1” switches the unit to Test mode, “2.
LCD, Switch, LED Checks, Foot Switch Operational Check” cannot be run
alone.
