power you have left.
* You may find that it is a good idea to keep a
battery installed in the unit even while using
an adaptor. That way your playing won't be
disrupted even if the adaptor is accidentally
disconnected.
* If you are going to use an AC adaptor, be sure
to use the specified unit (BOSS PSA-Series).
Use of any other adaptor may result in dam-
age, malfunction or electric shock.
Also, if you are not going to be using it for an
extended period of time, disconnect the AC
adaptor from the AC outlet.
