PREPARATION
POWER SOURCES
You can power your scanner from any of three sources:
• Built-in rechargeable battery pack
• Standard AC power using the supplied AC adapter/
charger
• Vehicle battery power using an optional DC ciga-
rette-lighter power cable
Using the Rechargeable Battery Pack
You must charge your scanner’s built-in rechargeable
battery pack before you can use it to power the scanner.
Your scanner has a built-in charging circuit that lets you
charge the rechargeable battery pack while it is in the
scanner.
To charge the battery pack, simply connect the supplied
AC adapter/charger or an optional DC cigarette-lighter
power cable to the scanner’s
EXT. PWR
jack. See “Using
Standard AC Power” on Page 9 or “Using Vehicle Bat-
tery Power” on Page 10.
It takes about 14–16 hours to recharge a battery pack
that is fully discharged. (You can operate the scanner
while recharging the battery pack, but charging takes
longer).
Notes:
• The scanner automatically stops charging the bat-
tery pack when it is fully charged, even if the sup-
plied AC adapter/charger or a DC cigarette-lighter
power cable is still connected to the scanner.
• A rechargeable battery pack lasts longer and deliv-
ers more power if you occasionally let it fully dis-
charge. To do this, simply use the scanner until the
low battery indicator appears. Then fully charge the
battery pack.
If the battery pack doesn’t power the scanner even after
you charge it, you must replace it. You can order a re-
placement battery pack from your local RadioShack
store.
