Cautions:
h You must use a DC adapter that supplies 9 volts and de-
livers at least 200 milliamps. Its center tip must be set to
negative, and its plug must correctly fit the scanner's PWR/
CHG jack. The recommended adapter meets these speci-
fications. Using an adapter that does not meet these speci-
fications could damage the scanner or the adapter.
h To protect your vehicle's electrical system, always plug
the adapter into the scanner before you plug it into your
vehicle's cigarette-lighter socket. Always unplug the
adapter from the vehicle's cigarette-lighter socket before
you unplug it from the scanner.
Plug the adapter's barrel plug into the scanner's PWR jack.
Then plug the adapter's power module into your vehicle's
cigarette-lighter socket.
Charging a Rechargeable Battery Pack/
Rechargeable Batteries
Your scanner has a built-in charging circuit that lets you
charge a rechargeable battery pack or rechargeable nickel-
cadmium batteries while it is in the scanner. To charge it,
simply connect an AC or DC adapter to the scanner's CHG
jack.
It takes about 14-16 hours to recharge a battery pack (re-
chargeable batteries) that is fully discharged. You can oper-
ate the scanner while recharging the battery pack (recharge-
able batteries), but charging takes longer.
Note: A rechargeable battery pack (rechargeable batteries)
lasts longer if you let it fully discharge once a month. To do
this, simply use the scanner until BATT flashes and the scan-
ner beeps about every 3 seconds. Then fully charge it.
Important! At the end of a rechargeable battery pack or bat-
teries useful life, it must be recycled or disposed of properly.
Contact your local, county, or state hazardous waste man-
agement authorities for information on recycling or disposal
programs in your area. Some options that might be avail-
able are: municipal curb-side collection, drop-off boxes a
retailers such as your local store, recycling collection cen-
ters, and mailback programs.
