• 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 other debris.
CHARGING NICKEL-CADMIUM BATTERIES
The scanner has a built-in charging circuit that lets you recharge nickel-
cadmium batteries while they are in the scanner. To charge the batter-
ies, remove the plug from the scanner’s
CHARGE jack and simply con-
nect an AC adapter or a DC Universal Adapter to the jack (see “Using
Standard AC Power” or “Using Vehicle Battery Power”).
Warning: Do not connect either adapter to the scanner’s CHARGE jack
if you installed non-rechargeable batteries (standard, extra-life, or alka-
line). Non-rechargeable batteries become hot and can even explode if
you try to recharge them.
It takes about 14 to 16 hours to recharge batteries that are fully dis-
charged. You can operate the scanner while recharging the nickel-
cadmium batteries, but the charging time is lengthened.
Note: Nickel-cadmium batteries last longer and deliver more power if
you occasionally let them fully discharge. To do this, simply use the
scanner until it begins beeping every 15 seconds and
BATT.LO ap-
pears on the display. Then fully charge the batteries.
Important! At the end of a rechargeable battery’s useful life, it must be
recycled or disposed of properly. Contact your local, county, or state
hazardous waste management authorities for information on recycling
or disposal programs in your area. Some options that might be available
are: municipal curb-side collection, drop-off boxes at retailers, recycling
collection centers, and mail-back programs.
