The Basics 8
RECHARGEABLE inside the battery compartment to
RECHARGEABLE, install the batteries in the scanner,
and connect an external AC or DC adapter to the
scanner's DC 6V jack (see “using AC power” on
Page 10 or “using vehicle battery power” on
Page 11).
Warning: Do not connect either the AC or DC
adapter to the scanner if non-rechargeable batteries
(such as alkaline batteries) are installed in the scan-
ner and ALKALINE/RECHARGEABLE is set to
RECHARGEABLE, or if 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 Ni-Cd or Ni-MH batteries for the first
time, charge them for 14 hours to bring them to a
full charge.
Discharged batteries take about 14 hours to fully
recharge.
Notes:
• Ni-Cd batteries last longer and deliver more
power if you occasionally let them fully
discharge. To do this, simply use the scanner
until it beeps every 15 seconds and flashes.
• To prevent damage to Ni-Cd batteries, never
charge them in an area where the temperature is
above 113°F (40°C) or below 40°F (4°C).
