USING VEHICLE BATTERY POWER
You can power the scanner from your vehicle’s cigarette lighter socket
with an optional DC cigarette lighter power cord (such as Cat. No. 270-
1533).
Cautions:
• The recommended DC power cord supplies 12 volts and delivers
at least 200 milliamps. Its center tip is set to positive and its plug
properly fits the scanner’s
POWER and CHARGE jacks. Using a
power cord that does not meet these specifications could damage
the scanner or the power cord.
• To protect your vehicle’s electrical system, always plug the power
cord into the scanner before you plug it into your vehicle’s ciga-
rette-lighter socket. Always unplug the power cord from the vehi-
cle’s cigarette lighter socket before you unplug it from the scanner.
Note: The scanner receives a 12-volt input at the CHARGE or POWER
jack and reduces it to the 6 volts required by the scanner.
1. Plug the power cord’s barrel plug into your scanner’s POWER jack.
2. Plug the other end of the power cord into your vehicle’s cigarette-
lighter socket.
Notes:
• If you installed rechargeable nickel-cadmium batteries in the
scanner, remove the plastic cap from the CHARGE jack and put
the cap in the POWER jack. Connect the DC power cord to the
CHARGE jack. This powers the scanner and recharges the bat-
teries at the same time. See “Charging Nickel-Cadmium Batter-
ies.”
