Radio Shack 120-0615 - Manual (Page 3)

Its center tip is set to negative. Using an adapter that does
not meet these specifications could seriously damage the radio or
the adapter.
Be sure you connect the AC adapter to the radio before you
connect it to the AC outlet, and then disconnect it from the AC
outlet before you disconnect it from the AC outlet before you
disconnect it from the radio. Otherwise, the unconnected plug
might touch some metal and damage the adapter.
Follow these steps to power the radio from a standard AC outlet.
1. Set the adapter's voltage switch to 4.5V.
2. Insert the green-tipped Adaptaplug's black end into the AC adapter's
cord so it reads TIP NEG.
3. Insert the Adaptaplug's other end into the radio's DC 4.5V jack.
NOTE: Connecting an AC adapter automatically disconnects internal
battery power.
4. Plug the adapter into a standard AC outlet.
USING VEHICLE BATTERY POWER
You can power the radio from a vehicle's battery using an optional DC
adapter, such as Radio Shack Cat. 270-1560 (not supplied)
CAUTIONS: The vehicle must have a 12-volt DC, negative-ground electrical
system.
The recommended DC adapter supplies 4.5 volts, delivers 300
milliamps, and its plug correctly fits the radio's DC 4.5V
jack. Its center tip is set to negative. Using an adapter
that does not meet these specifications could seriously damage
the radio or the adapter.
Be sure you connect the DC adapter to the radio before you con-
nect it to the cigarette-lighter socket, and then disconnect it
from the radio. Otherwise, the unconnected plug might touch
some metal and damage the adapter.
Follow these steps to power the radio from a vehicle's battery.
1. Set the adapter's voltage switch to 4.5V.
