PRO-24 (200-0503) Power Sources Faxback Doc. # 3951
You can power your scanner from any of these power sources:
Internal batteries
Standard AC power (using an optional AC adapter)
Vehicle battery (using an optional DC adapter)
Using Internal Batteries
You can power your scanner with four AA batteries. For the longest
life and best performance, we recommend alkaline batteries such as
Cat. No. 23-552. Or, you can use rechargeable nickel-cadmium batteries
(Cat. No. 23-125).
Follow these steps to install or replace batteries.
1. If the scanner is on, turn VOLUME/OFF fully counterclockwise until it
clicks to turn it off.
2. Press down the tab on the battery compartment cover and lift open the
compartment.
3. Remove any old batteries from the compartment and cover.
Caution: Always dispose of old non-rechargeable batteries promptly
and properly. Do not bury or burn them.
4. Install two batteries in the compartment and two in the cover as
indicated by the polarity symbols (+ and -) marked inside the
compartment and cover.
5. Replace the cover.
If L appears on the display or your scanner beeps every 15 seconds,
immediately replace or recharge all four batteries. See "Important
Information About the External Power Jacks" and "Charging Nickel-Cadmium
Batteries."
Important Information About the External Power Jacks
The scanner has two external power jacks - POWER and CHARGE. It is
important that you understand the purpose of each jack before you connect
any adapter to the scanner.
The POWER jack powers the scanner and disconnects the internal batteries.
You can use this jack with either an AC or DC adapter, regardless of the
type of batteries you installed.
The CHARGE jack powers the scanner and also charges the internal
batteries. Use the CHARGE jack only when rechargeable nickel-cadmium
batteries are installed.
Warning: Never use the CHARGE jack with non-rechargeable batteries,
they become very hot and could explode.
Using AC Power
To operate the scanner from AC power, you need an AC adapter such as
Cat. No. 273-1652.
Cautions: You must use an AC adapter that supplies 12 volts and
delivers at least 200 milliamps. Its center tip must be
set to positive, and its plug must correctly fit the
scanner's POWER jack. The recommended adapter meets these
specifications. Using an adapter that does not meet these
specifications can damage your scanner and the adapter.
Always plug the adapter into the scanner before you plug it
into the AC outlet. Always unplug the adapter from the AC
outlet before you unplug it from the scanner.
Follow these steps to connect an AC adapter to the scanner.
1. Connect the adapter's green barrel plug to the adapter's cord and set
the barrel plug's tip to positive.
2. Plug the adapter's barrel plug into your scanner's POWER jack.
Note: If you have installed rechargeable nickel-cadmium batteries in
the scanner, you can connect the AC adapter to the CHARGE jack.
This powers the scanner and recharges the batteries at the same
time. See "Charging Nickel-Cadmium Batteries."
3. Plug the adapter's power module into a standard AC outlet.
Using Vehicle Battery Power
You can power the scanner from your vehicle's battery power, using a DC
adapter (Cat. No. 270-1533).
Cautions: You must use a DC adapter that supplies 12-volts and
delivers at least 200 milliamps. Its center tip must be
set to positive, and its plug must correctly fit the
Scanner's POWER jack. The recommended adapter meets these
specifications. Using an adapter that does not meet these
specifications can damage your scanner and the adapter.
Your vehicle must have a 12-volt negative-ground electrical
system.
To protect your vehicle's electrical system, always plug
the adapter into the scanner before you plug it into your
vehicle's cigarette socket. Always unplug the adapter from
the vehicle's cigarette-lighter socket before you unplug it
from the scanner.
Follow these steps to connect a DC adapter to the scanner.
1. Plug the adapter's barrel plug into your scanner's POWER jack.
Note: If you have installed rechargeable batteries, you can connect
the DC adapter to the CHARGE jack. This powers the scanner and
recharges the batteries at the same time.
2. Insert the other end of the adapter into your vehicle's cigarette
lighter socket.
Note: If the scanner does not operate properly when you use a DC
adapter, unplug the adapter from the lighter socket and clean
the socket to remove ashes and other debris.
Charging Nickel-Cadmium Batteries
This scanner has a built-in charging circuit that lets you recharge
nickel-cadmium batteries while they are in the scanner. To charge the
batteries, simply connect an AC or DC adapter (Cat. No. 273-1652 or
270-1533) to the scanner's CHARGE jack.
Warning: Do not connect either adapter to the scanner's CHARGE jack
if you installed non-rechargeable batteries (standard,
extra-life, or alkaline). Non-rechargeable batteries become
hot and can even explode if you try to recharge them.
It takes 10 to 18 hours to recharge batteries that are fully
discharged. You can operate your scanner while recharging
nickel-cadmium batteries, but it takes longer to fully
charge the batteries.
Cautions: Do not overcharge nickel-cadmium batteries.
To prevent damaging nickel-cadmium batteries, never charge
them in an area where the temperature is above 90 degrees F
or below 40 degrees F.
Important: Your scanner is capable of using rechargeable nickel
cadmium batteries. At the end of the batteries' useful
life, they 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.
