■ Using the Anti-Feedback (ANTI-F.BACK) Function
Then anti-feedback function suppresses the feedback produced by the resonance of the guitar body and other sources.

where feedback tends to occur.

The feedback point is automatically detected and the feedback is suppressed.

* If no input audio is detected, anti-feedback is not applied.

With the anti-feedback function operational (when the ANTI-F.BACK icon is lit), hold down the ANTI-F.BACK
button for at least one second to cancel the function.
■ Canceling the Auto Backlight Off Function
* To reduce battery consumption, the PREAMP is set at turning off the power so that the backlighting is switched off after
thirty seconds (the Auto Backlight Off function).
Holding down the LIGHT button for at least one second switches off the Auto Backlight Off function.
The LIGHT icon appears at the upper left of the display.
Holding down the button again for at least one second reactivates the Auto Backlight Off function.
