ME-50, ME-50B: (b) Flashing in the Display

Tags: me-50,me-50b
"b" flashing in the display indicates that the AA batteries are low.
Replace with six new AA (Alkaline LR6 type) batteries.

Tip: If desired, the ME-50 can be powered with a BOSS PSA-120 power supply (optional) instead of batteries. Contact any Boss or Roland dealer to purchase one.
