Possible Cause and Solution

This instrument has not been plugged in properly. Securely insert the female plug into

the socket on this instrument, and the male plug into a proper AC outlet (page 11).

This is normal when electrical current is being applied to the instrument.

The noise may be due to interference caused by the use of a mobile phone in close

proximity to this instrument. Turn off the mobile phone, or move it further away from

this instrument.

• The Master Volume is set too low. Set it to an appropriate level using the [MASTER

VOLUME] control.

• Make sure a pair of headphones is not connected to the headphones jack.

• Make sure that Local Control (page 29) is ON.

The pedal cord may not be properly connected. Make sure to securely insert the pedal

cord into the [PEDAL] jack (page 36).
