Installing Batteries
If eight commercially available rechargeable Ni-MH batteries
(AA, HR6) are installed, you’ll be able to play this unit without
connecting the AC adaptor.
* If you handle batteries improperly, you risk explosion and fluid
leakage. Make sure that you carefully observe all of the items
related to batteries that are listed in “USING THE UNIT SAFELY”
and “IMPORTANT NOTES” (leaflet “USING THE UNIT SAFELY” and
Owner’s manual (p. 32)).
* We recommend that you keep batteries installed in the unit
even though you’ll be powering it with the AC adaptor. That
way, you’ll be able to continue a performance even if the cord of
the AC adaptor gets accidently disconnected from the unit.

Depending on the thickness of the cable, you might not be able
to close the ferrite core with the cable wrapped once around
