Power Sources

Using AC Power

The scanner's supplied AC adapter lets you power the scanner from a 
standard AC outlet.  To connect power to the scanner, insert the AC 
adapter's barrel plug into the DC 12V jack on the back of the scanner, 
then plug the AC adapter into a standard AC outlet.

WARNING:  Do not use the AC adapter's polarized plug with an extension
          cord receptacle unless the blades can be fully inserted to
          prevent blade exposure.

CAUTIONS:  You must use a Class 2 power source that supplies 12 volts DC
           and delivers at least 300 mA.  Its center tip must be set to
           positive and its plug must fit the PRO-2015's DC 12V jack.  The
           supplied adapter meets these specifications.  Using an adapter
           that does not meet these specifications could damage the
           PRO-2015 or the adapter.

           Be sure to connect the AC adapter to the scanner before you
           connect it to an AC outlet, and disconnect the AC adapter from
           the AC outlet before you disconnect it from the scanner.

Using DC Power

You can power your scanner from your vehicle's cigarette-lighter socket 
with an optional DC adapter, such as RadioShack Cat. No. 270-1533.

CAUTIONS:  You must use a power source that supplies 12 volts DC and
           delivers at least 300 mA.  Its center tip must be set to
           positive and its plug must fit the PRO-2015's DC 12V jack.
           The recommended adapter meets these specifications.  Using
           an adapter that does not meet these specifications could
           damage the PRO-2015 or the adapter.

           Be sure to connect the DC adapter to the scanner before you
           connect it to the cigarette-lighter socket, and disconnect
           the DC adapter from the cigarette-lighter socket before you
           disconnect it from the scanner.

To connect a DC adapter, insert its 5.5 mm outer diameter/2.1 mm inner 
diameter barrel plug into the DC 12V jack on the back of the scanner, then 
plug the adapter into your vehicle's cigarette-lighter socket.

Notes:  If you use a DC adapter and your vehicle's engine is running, you
        might hear electrical noise on the scanner caused by the engine.
        This is normal.

        Mobile use of this scanner is unlawful or requires a permit in
        some areas.  Check the laws in your area.

Connecting an Antenna

Connecting the Supplied Antenna

You must install an antenna before you can operate the scanner.

The supplied telescoping antenna helps your scanner receive strong local 
signals.  To install the antenna, thread it clockwise into the hole on top 
of the scanner.

The scanner's sensitivity depends on its location and the antenna's 
length.  For the best reception of the transmissions you want to hear, 
adjust the antenna's length according to the chart below.

    Frequency       Antenna Length

    29-174 MHz      Extend fully
    380-512 MHz     Extend 2 segments

Connecting an Outdoor Antenna

Instead of the supplied antenna, you can connect an outdoor base-station 
or mobile antenna (not supplied) to your scanner.  Your local RadioShack 
store sells a variety of antennas.

Choose the one that best meets your needs.

When deciding on an outdoor antenna and its location, consider these 
points:

  The antenna should be located as high as possible.

  The antenna and antenna cable should as far as possible from sources of
  electrical noise (appliances, other radios, and son on).

  The antenna should be vertical for the best performance.

To connect an optional base-station or mobile antenna, first remove the 
supplied antenna from the scanner.  Always use 50-Ohm coaxial cable, such 
as RG-58 or RG-8, to connect the base-station or mobile antenna.  For 
lengths over 50 feet, use RG-8 low-loss dielectric coaxial cable.  If the 
antenna cable's connector does not fit in the ANT jack on the back of the 
scanner, you might also need a PL-259-to-Motorola antenna plug adapter, 
such as Cat, No. 278-208.  Your local RadioShack store carries a wide 
variety of coaxial antenna cable and connectors.

Once you choose an antenna, follow the mounting instructions supplied with 
the antenna.  Then route the antenna's cable to the scanner and connect 
the cable to the ANT jack.

WARNING:  Use extreme caution when you install or remove an outdoor
          antenna.  If the antenna starts to fall, let it go!  It could
          contact overhead power lines.  If the antenna touches a power
          line, contact with the antenna, mast, cable, or guy wires can
          cause electrocution and death.  Call the power company to remove
          the antenna.  Do not attempt to do so yourself.

CAUTION:  Do not run the cable over sharp edges or moving parts that might
          damage it.
