Cautions:
• You must use an AC adapter that supplies at least 7.5 volts DC power and
delivers at least 300 milliamps. Its center tip must be set to positive, and its
barrel plug must properly fit the Listener's
adapter meets these requirements. Using an adapter that does not meet
these requirements could damage the Listener or the adapter.
• To prevent damage to the Listener or the adapter, be sure you connect the
adapter to the Listener before you plug it into the AC outlet, and unplug the
adapter from the AC outlet before you unplug it from the Listener.
Insert the adapter's barrel plug into the Listen-
er's jack, then plug the adapter into a
9V DC
standard AC outlet.
