Notes:
• If you won’t be using the Concert-
mate 575 for a week or more, or if
you plan to use it only with AC or
vehicle battery power, remove the
batteries.
• If the Concertmate 575 sounds
weak or does not work properly,
replace all five batteries. Do not
mix old and new batteries.
Caution: Dispose of old batteries
promptly and properly.
USING AC POWER
You can power your Concertmate 575
from a standard AC outlet using a 7.5-
volt AC adapter (not supplied), such as
RadioShack Cat. No. 273-1662.
Cautions:
• You must use an AC adapter that
supplies at least 7.5 volts and
delivers at least 300 milliamps. Its
center tip must be set to negative,
its voltage switch must be set to
7.5 volts, and its plug must cor-
rectly fit the Concertmate 575’s
DC 7.5V
jack. The recommended
adapter meets these specifica-
tions. Using an adapter that does
not meet these specifications, or
using the recommended adapter
at a different voltage setting, could
damage the Concertmate 575 or
the adapter.
• Always plug the AC adapter into
the Concertmate 575 before you
plug it into the AC outlet. Always
unplug the AC adapter from the
AC outlet before you unplug it
from the Concertmate 575.
