X Make sure the power is turned off.
Y If the adapter has a voltage switch, set the switch 
to 6V.
Z Insert the Adaptaplug into the DC adapter's cord 
so it reads TIP +. Then, insert the Adaptaplug into 
the scanner's DC 6V jack.
[ Plug the other end of the adapter into your 
 vehicle's cigarette-lighter socket.
If rechargeable batteries are installed and 
ALKALINE/RECHARGEABLE is set to 
RECHARGEABLE, the adapter powers the scanner 
and recharges the installed batteries at the same 
time.
Note: If the scanner does not operate properly 
when you use a DC adapter, unplug the adapter 
from the cigarette-lighter socket and clean the 
socket to remove ashes and debris.
