You can power your Concertmate 690
from a standard AC outlet using a 9-
volt AC adapter, such as Cat. No. 273-
1656.
Cautions:
• You must use an AC adapter that
supplies 9 volts of DC power and
delivers at least 500 milliamps. Its
center tip must be set to negative,
and its barrel plug must properly
fit the Concertmate 690’s
DC 9V
jack. The recommended adapter
meets these specifications. Using
an adapter that does not meet
these specifications could dam-
age the Concertmate 690 or the
adapter.
