Using AC Power
You can power your Concertmate 970
from standard AC power using a 9-volt
AC adapter (not supplied), such as Ra-
dioShack Cat. No. 273-1656.
Cautions:
• You must use an AC adapter that
supplies 9 volts and delivers at
least 800 milliamps. Its center tip
must be set to negative, and its
plug must correctly fit the Concert-
mate 970’s
DC 9V jack. The rec-
ommended adapter meets these
specifications. Using an adapter
that does not meet these specifi-
cations could damage the Con-
certmate 970 or the adapter.
• Always plug the AC adapter into
the Concertmate 970 before you
plug it into the AC outlet. Always
unplug the AC adapter from the
AC outlet before you unplug it
from the Concertmate 970.
• Be sure POWER/MODE is set to
OFF when you connect or discon-
nect the adapter.
1. Insert the adapter’s barrel plug
into the DC 9V jack on the back of
the Concertmate 970.
2. Plug the adapter into a standard
AC outlet.
