Using Ac Power; Using Vehicle Battery Power - Radio Shack PRO-99 Owner's Manual

3. Place the battery holder into the battery compartment.
Caution: The battery holder fits only one way inside the battery compartment. Do not force it.
4. Replace the cover.
When Low Battery! flashes on the display and the scanner beeps, or if the scanner stops operating properly,
replace the batteries.

USING AC POWER

You can power the scanner using a 6V, 300-mA AC adapter and a size C Adaptaplug™ adapter (neither
supplied). Both are available at your local RadioShack store.
Cautions:
! You must use a Class 2 power source that supplies 6V DC and delivers at least 300 mA. Its center tip must
be set to positive and its plug must fit the scanner's PWR DC 9V jack. Using an adapter that does not meet
these specifications could damage the scanner or the adapter.
. Always connect the AC adapter to the scanner before you connect it to AC power. When you finish,
disconnect the adapter from AC power before you disconnect it from the scanner.
To power the scanner using an AC adapter, attach the Adaptaplug to the AC adapter so the tip reads positive
(+), then insert the Adaptaplug into the scanner's PWR DC 9V jack. Connect the other end of the adapter to a
standard AC outlet.

USING VEHICLE BATTERY POWER

You can power the scanner from a vehicle's 12V power source (such as a cigarette-lighter socket) using a 6V,
300-mA DC adapter and a size C Adaptaplug (neither supplied.) Both are available at your local RadioShack
store.
Cautions:
! You must use a Class 2 power source that supplies regulated 6V DC and delivers at least 300 mA. Its center
tip must be set to positive and its plug must fit the scanner's PWR DC 6V jack. Using an adapter that does not
meet these specifications could damage the scanner or the adapter.
. Always connect the AC adapter to the scanner before you connect it to the power source. When you finish,
disconnect the adapter from the power source before you disconnect it from the scanner.
To power the scanner using a DC adapter, attach the Adaptaplug to the DC adapter so the tip reads positive
(+), set the adapter's voltage switch to 9V, then insert the Adaptaplug into the scanner's PWR DC 6V jack.
