Miscellaneous

Automatic dim of display

 - in the lower right side of the display an Ambilight sensor detects the 

strength of the surrounding light and automatically adjusts the display brightness accordingly. This way 

you will always have appropriate brightness on the display under all conditions and this feature even 

extends the battery life when max light is not necessary.

Indication of current settings

 - When inserting a jack cable to the input, the pedals status is 

displayed. Default settings are: Tuning: E, Pitch Reference: 440 Hz, Display mode: Needle.
