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.”
