Using Vehicle Battery Power

DC adapter such as RadioShack Cat. No. 273-1815.

DC and delivers at least 800 mA. Its center tip
must be set to positive, and its plug must fit the
transceiver's DC 9V jack. The recommended adapter meets
these specifications. Using an adapter that does not meet
these specifications could damage the transceiver or the
adapter.
• Always plug the adapter into the transceiver before you plug
it into the cigarette-lighter socket, and unplug the adapter
from the cigarette-lighter socket before you unplug it from
the transceiver.
1. Set the adapter's voltage switch to 9V.
2. Insert the 3.8 mm outer diameter/1.1 mm inner diameter
plug (Cat. No. 273-1712, not supplied) into the adapter's
cord, so it reads +TIP .

socket in the vehicle.
