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.)

• 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

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.
