Installing Batteries

You can power your scanner with four AA batteries (not supplied).  For the 
best performance and longest life, we recommend RadioShack alkaline 
batteries.

You can use either the black non-rechargeable battery holder or the yellow 
rechargeable battery holder (both supplied) to hold the batteries.  If you 
use the yellow battery holder, we recommend nickel-cadmium or nickel-metal 
hydride batteries (not supplied).

CAUTIONS: Use only fresh batteries of the required size and recommended
          type.     

          Do not mix old and new batteries, different types of batteries 
          (standard, alkaline, or rechargeable) or rechargeable batteries
          of different capacities.

WARNING: Never install non-rechargeable batteries in the yellow
         rechargeable battery holder.  Non-rechargeable batteries can get
         hot or explode if you try to recharge them.

Follow these steps to install batteries.

1.  Press down on the battery compartment cover then slide the cover in 
    the direction of the arrow to remove it.

2.  If you are using non-rechargeable batteries, place them into the black 
    holder, as indicated by the polarity symbols (+ and -) marked on the
    holder.  Or, if you are using rechargeable batteries, place them into
    the yellow holder as indicated by the polarity symbols (+ and -)
    marked on the holder.
  
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 [B] flashes on the display and the scanner beeps, or if the scanner 
stops operating properly, replace the batteries.

WARNING: Dispose of old batteries promptly and properly.  Do not burn or
         bury them.

CAUTION: If you do not plan to use the scanner with batteries for a month
         or more, remove the batteries.  Batteries can leak chemicals that
         can destroy electronic parts.

Using AC Power

You can power the scanner using a 9V, 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 9V 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 9V, 300-mA DC adapter and a size C 
Adaptaplug (neither supplied).  Both are available at your local Radio 
Shack store.

CAUTIONS: You must use a power source that supplies regulated 9V 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 DC 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 9V jack. Plug the 
other end of the DC adapter into your vehicle's cigarette-lighter socket.

Note: If you use a cigarette-lighter power cable and your vehicle's engine
      is running, you might hear electrical noise from the engine while
      scanning.  This is normal.

Charging Rechargeable Batteries

Your scanner has a built-in charging circuit that lets you charge 
rechargeable batteries while they are in the scanner.  To charge 
rechargeable batteries, you need to use an AC adapter which supplies 9V 
(RadioShack Cat. No. 273-1767) or a DC adapter which supplies 10V (Cat. 
No. 273-1830).  Connect a size C Adaptaplug to the adapter's cable with 
the tip set to positive then insert the Adaptaplug into the scanner's PWR 
DC 9V jack.

Note:  Do not overcharge Ni-Cd batteries.  Overcharging causes them to get
       hot and shortens their life.

It takes between 14 and 16 hours to recharge Ni-MH or 7 and 8 hours to 
recharge Ni-Cd batteries that are fully discharged.  You can operate the 
scanner while recharging the batteries, but charging takes longer.

Note:  Ni-Cd batteries last longer and deliver more power if you 
       occasionally let them fully discharge.  To do this, simply use the
       scanner until [B] flashes on the display and the scanner beeps.
       Then fully charge the batteries.

IMPORTANT: This scanner can use Ni-Cd rechargeable batteries.  At the end 
           of a Ni-Cd battery's useful life, it 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 curbside collection, drop-off 
           boxes at retailers such as your local RadioShack store,
           recycling collection centers, and mail-back programs.

Connecting An Antenna

Connecting a Supplied Antenna

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

The supplied stub antenna helps your scanner receive most strong 
transmissions at events and makes the scanner easier to carry and use. The 
supplied flexible antenna provides slightly better reception and helps 
your scanner receive strong local signals.  Follow these steps to attach 
either antenna to the scanner.

1.  Align the slots around the antenna's connector with the tabs on the
    antenna jack.

2.  Press the antenna down over the jack and turn the antenna's base
    clockwise until it locks into place. 

Connecting an Outdoor Antenna

Instead of a supplied antenna, you can connect an outdoor base-station or 
mobile antenna (not supplied) to your scanner using a BNC connector.  Your 
local RadioShack store sells a variety of antennas.  Choose the one that 
best meets your needs.

When deciding on a mobile or base-station antenna and its location, 
consider these points:

  The antenna should be as high as possible on the vehicle or building.
  
  The antenna and its cable should be as far as possible from sources of 
  electrical noise, such as appliances or other radios.

  The antenna should be vertical for the best performance. 

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 scanner's antenna jack, you might also need a PL-259-to-BNC 
antenna plug adapter.  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, after removing a supplied antenna.  Then route the antenna's 
cable to the scanner and connect the cable to the scanner's antenna jack.

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

          Do not run the cable next to power cables or other antenna 
          cables. 

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.

Connecting An Earphone/Headphones

For private listening, you can connect an earphone or headphones with a 
1/8-inch (3.5-mm) plug to the (headphone symbol) jack on the top of the 
scanner.  (Your local RadioShack store carries a wide selection of 
earphones and headphones).  Connecting an earphone or headphones 
automatically disconnects the internal speaker.

Listening Safely

To protect your hearing, follow these guidelines when you use an earphone 
or headphones. 

  Set the volume to the lowest setting before you begin listening.  After
  you begin listening, adjust the volume to a comfortable level. 

  Do not listen at extremely high volume levels.  Extended high-volume
  listening can lead to permanent hearing loss. 

  Once you set the volume, do not increase it.  Over time, your ears adapt
  to the volume level, so a volume level that does not cause discomfort
  might still damage your hearing.

Traffic Safety

  Do not use an earphone or headphones with your scanner when operating a 
  motor vehicle or riding a bicycle in or near traffic.  Doing so can
  create a traffic hazard and could be illegal in some areas.

  If you use an earphone or headphones with your scanner while riding a 
  bicycle, be very careful.  Do not listen to a continuous transmission.
  Even though some earphones or headphones let you hear some outside
  sounds when listening at normal volume levels, they still can present a
  traffic hazard.

Connecting An Extension Speaker

In a noisy area, an amplified extension speaker (available at your local 
RadioShack store) might provide more comfortable listening.  Plug the 
speaker cable's 1/8-inch (3.5-mm) plug into your scanner's (headphone 
symbol) jack. 

Note:  Connecting an external speaker disconnects the scanner's internal 
       speaker.
