USING VEHICLE
BATTERY POWER
You can power your Concertmate 575
from your vehicle’s cigarette lighter
socket using a DC adapter (not sup-
plied), such as RadioShack Cat. No.
270-1560.
Cautions:
• You must use a DC 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 DC adapter into
the Concertmate 575 before you
plug it into the cigarette lighter
socket. Always unplug the DC
adapter from the cigarette lighter
socket before you unplug it from
the Concertmate 575.
1. Be sure MODE is set to POWER
OFF .
2. Plug the proper-sized barrel plug
into the adapter’s cable so it reads
– (negative) TIP.
3. Set the adapter’s voltage switch to
7.5 volts.
4. Insert the adapter’s other barrel
plug into DC 7.5V on the back of
the Concertmate 575.
5. Plug the other end of the adapter
into the vehicle’s cigarette lighter
socket.
