CAUTIONS
e When you don't use for a long period,
remove the battery to prevent current
leakage and leaking out of sticky sub-
stance.
e If battery voltage drops, effect becomes
inferior or no sound is produced. To
prevent that, replace the battery a little
earlier.
AC ADAPTOR (OPTION)
e Be sure to keep the battery snapped by
connector into the housing, when using
AC adaptor, too.
* Even if AC Adaptor cord comes out
during performance, operation imme-
diately changes to battery, causing no
trouble in continued performance.
ePower is switched on while a plug is
put into input jack. When you do not
use, keep the plug off the jack.
When you operate DS-1 from AC line, use AC Adaptor (DC9V) for DS-1.
