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 the
scanner's top.
The scanner's sensitivity depends on the antenna's length and various
environmental conditions. For the best reception of the transmissions you
want to hear, adjust the antenna's length.
Frequency Antenna Length
29-54 MHz Extend fully
108-400 MHz Collapse one segment
406-1300 MHz Collapse both 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 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 (appliances, other radios, etc.).
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, you might also
need a Motorola-to-BNC antenna plug adapter, such as RadioShack Cat. No.
278-117. 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 on the back of the scanner.
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 Power
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.
CAUTIONS: You must use a Class 2 power source that supplies 12V DC and
delivers at least 500 mA. Its center tip must be set to positive
and its plug must fit the scanner's DC 12V jack. The supplied
adapter meets these specifications. Using an adapter that does
not meet these specifications could damage the scanner or the
adapter.
Always connect the adapter to the scanner before you connect it
to the power source. When you finish, disconnect the DC adapter
from the power source before you disconnect it from the scanner.
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.
Using Your Vehicle's Battery Power
If your AC power fails (during an emergency, for example), you can power
your scanner from your vehicle's cigarette-lighter socket with an optional
DC cigarette lighter power cable, (not supplied).
To connect an optional DC cigarette-lighter power cable, insert its barrel
plug into the DC 12V jack on the back of the scanner, then plug the power
cable into your vehicle's cigarette-lighter socket.
CAUTIONS: You must use a power source that supplies 12V DC and delivers at
least 500 mA. Its center tip must be set to positive and its
plug must fit the scanner's DC 12V jack. The supplied adapter
meets these specifications. Using an adapter that does not meet
these specifications could damage the scanner or the adapter.
Always connect the adapter to the scanner before you connect it
to the power source. When you finish, disconnect the DC adapter
from the power source before you disconnect it from the scanner.
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.
Connecting An Extension Speaker
In a noisy area, an amplified extension speaker (available at your local
RadioShack store) positioned in the right place, 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.
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 front of the
scanner. (Your local RadioShack store carries a wide selection of
earphones and headphones). This automatically disconnects the internal
speaker.
Listening Safely
To protect your hearing, follow these guidelines when you use an earphone
or headphones.
Do not listen at extremely high volume levels. Extended high-volume
listening can lead to permanent hearing loss.
Set VOLUME to the lowest setting before you begin listening. After you
begin listening, adjust VOLUME to a comfortable level.
Once you set 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.
Understanding Your Scanner
Once you understand a few simple terms we use in this manual and
familiarize yourself with your scanner's features, you can put the scanner
to work for you. You simply determine the type of communications you want
to receive, then set the scanner to scan them.
A frequency is the tuning location of a station (expressed in kHz or MHz).
To find active frequencies, you can use the search function.
You can also search the service-search banks, which are preset groups of
frequencies categorized by type of service.
When you find a frequency, you can store it into a programmable memory
location called a channel, which is grouped with your other channels in a
channel-storage bank. You can then scan the channel-storage banks to see
if there is activity on the frequencies stored there. Each time the
scanner finds an active frequency, it stays on that channel until the
transmission ends.
A Look At the Front Panel

Understanding Banks
Channel Storage Banks
To make it easier to identify and select the channels you want to listen
to, channels are divided into 20 banks of 50 channels each. Use each
channel-storage bank to group frequencies, such as those used by the
police department, fire department, ambulance services, or aircraft (see
"Guide to the Action Bands" in Faxback Doc. # 17653).
For example, the police department might use four frequencies, one for
each side of town. You could program the police frequencies starting with
Channel 1 (the first channel in bank 1) and program the fire department
frequencies starting with Channel 51 (the first channel in bank 2).
Service Banks
The scanner is preprogrammed with the frequencies allocated by public
safety, police, fire/emergency, aircraft, and weather services. This is
handy for quickly finding active frequencies instead of searching through
an entire band (see "Searching Service Banks" in Faxback Doc. # 58685).
Understanding Trunking
In the past, groups that broadcast frequently, such as police departments,
were restricted to transmitting on just a few frequencies. This resulted
in heavy traffic and often required 2-way radio users to wait for a
specific frequency to clear before transmitting.
Trunked systems allow more groups of 2-way radio users to use fewer
frequencies. Instead of selecting a specific frequency to transmit on, a
trunked system chooses one of several frequencies when the 2-way radio
user presses PTT (push to talk). The system automatically transmits the
call on that frequency, and also sends a code that identifies that 2-way
radio user's transmission on a data channel.
You can set this scanner to monitor the data channel frequency, so you can
hear both the call and response transmissions for that 2-way radio user
and therefore follow the conversation. (You cannot listen to the data
channel itself in trunking mode.)
