If
BATT.Lo
flashes and the scanner beeps every 15
seconds, replace (standard/alkaline) or recharge (re-
chargeable nickel-cadmium) the batteries.
Caution: Always dispose of old batteries promptly and
properly. Do not bury or burn them.
Charging Nickel-Cadmium Batteries
The scanner has a built-in circuit that lets you recharge
nickel-cadmium batteries while they are in the scanner.
To charge the batteries, set
ALKALINE JACK NI-
CD
to
NI-CD
, install the nickel-cadmium batteries in the
scanner, and connect an external AC or DC adapter to
the scanner’s
POWER
jack (see “Using AC Power” on
Page 12 or “Using Vehicle Battery Power” on Page 13).
Warning: Do not connect either adapter to the scanner
if non-rechargeable batteries (such as alkaline batter-
ies) are installed in the scanner and
ALKALINE JACK
NI-CD
is set to
NI-CD
, or you are unsure of the
switch’s position. Non-rechargeable batteries will get
hot and can even explode if you try to recharge them.
Before you use nickel-cadmium batteries for the first
time, charge them at least 24 hours to bring them to a
full charge.
Discharged batteries take about 10 to 18 hours to fully
recharge. If you use the scanner while the batteries are
charging, charging takes longer.
Notes:
• Nickel-cadmium batteries last longer and deliver
more power if you occasionally let them fully dis-
charge. To do this, simply use the scanner until it
beeps every 15 seconds and
BATT.Lo
flashes.
• To prevent damage to nickel-cadmium batteries,
never charge them in an area where the tempera-
ture is above 113°F or below 40°F.
