receiver or the adapter.
Follow these steps to use AC power.
1. Set the adapter’s voltage switch to
6V .
2. Line up the 5.5 mm outer diam-
eter/2.1 mm inner diameter
barrel plug with the adapter’s
socket so it reads –TIP, and insert
the plug.
3. Insert the barrel plug into the re-
ceiver’s DC IN 6V jack.
4. Plug the adapter into a standard
AC outlet.
Note: Using an adapter disconnects
the primary power batteries.
DC Power
With an optional DC adapter, such as
Radio Shack Cat. No. 270-1562, you
can power the receiver from your vehi-
cle’s battery.
Cautions:
• You must use a DC adapter that
supplies 6 volts with the center tip
set to negative. It must deliver at
least 400 milliamps, and its plug
must properly fit the receiver’s
DC
IN 6V jack. Using an adapter that
does not meet these specifica-
tions could damage the receiver
or the adapter.
• To protect your vehicle’s electrical
system, be sure the adapter is
connected to the cigarette-lighter
socket only when it is also con-
nected to the receiver.
