SCANNING LEGALLY
most every transmission your scanner
can receive. However, there are some
transmissions you should never intentionally listen to. These include:
• telephone conversations (cellular,
cordless, or other p rivate means of
telephone signal transmission)
• pager transmissions
• any scrambled or encrypted transmissions
According to the Electronic Communications Privacy A ct (ECPA), you are subject to fines and possible imprisonmen t

Connecting an Outdoor
Antenna
Instead of the supplied antenna, you can
connect an outdoor base-st ation antenna (not supplied) t o your scanner. Your
local RadioShack st ore sells a va riety of
antennas. Choose the one that best
meets your needs.
When deciding on a base-s tation ant enna and its location, consider these
points:
• The antenna should be as high as
possible on the house.
• The antenna and its cable should be
as far as possible from sources of
electrical noise such as appliances
or other radios.
The scanner’s sensitivity depends on
the antenna’s length and various environmental conditions. For the best re-

• The antenna should be vertical for
the best performance.
To connect a base-station antenn a, first
remove the supplied antenna from the
scanner. Always use 50-ohm coaxial cable, such as RG-58 or RG-8, to connec t
the base-station 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

UNDERSTANDING BANKS AND BANDS
You can store freq uencies into either a
programmable memo ry loc ati on c all ed a
channel, or a temporary memory location called a monitor me mory. You can
store a frequency in each of the scanner’s channels (up to 200 ) and up to 10
monitor memories.
Your scanner also has eight frequency
bands, each covering a specific range of
frequencies you can search.
CHANNEL-STORAGE
BANKS
To make it easier to ident ify and select
the frequencies you want to listen to, the
scanner’s channels are divided into 10
channel-storage banks (1–9 and 0) of 20
channels each. You can use each
channel-storage ba nk to group frequencies, such as those used by the police
department, fire departmen t, ambul ance
services, and amateur radio operators
(see “Guide to the Action Bands” on
Page 23).
MONITOR MEMORIES
Monitor memories are temporary storage areas where you can store up to ten
frequencies during a search while you
decide whether to save them int o channels. You can man ual ly select and listen
to frequencies stored in monitor memories.
FREQUENCY BANDS
Your scanner has eight frequency
bands, each covering a specific range of
frequencies. You can search these
bands for specifi c bro adcasts by repe atedly pressing
displays the band you want.
For example, you can search through all
frequencies between 29.000 and 54.000
MHz for specific broadcasts by repeatedly pressing
pears. The scanner then automatically
searches the frequencies in that band.

For example, there might be three or
four police departments in your area,
each using several different frequencies.
Additionally, there might be other law
enforcement agenc ies suc h as stat e po lice, county sheriffs, or SWAT teams
that use their own frequencies. You
could program all law enforcement frequencies starting with Channel 1 (the
first channel in Bank 1), then program
the fire department, paramedic, and other public safety freq uen ci es s tarting with
Channel 21 (the first channel in Bank 2).

DELAY
Many agencies use a two-way radio system that might have a pause of sever al
seconds between a query and a reply.
To avoid missing a reply, you can program a 2-second delay into any of your
scanner’s channels or frequencies.
Then, when the scanner stops on the
channel,
continues to monitor the channel for 2
seconds after the transmission stops before it resumes scanning or searching.
You can program a 2-second delay in either of the following ways:

Note:
FREQUENCY CONVERSION
The tuning location of a s tation can be expressed in frequency (kHz or MHz) or in
wavelength (meters). The following information can help you make the necessary
conversions.
1 MHz (million) = 1,000 kHz (thousand)
To convert MHz to kHz, multiply the number of megahertz by 1,000:
9.62 (MHz) × 1000 = 9620 kHz
To convert from kHz to MHz, divide the number of kilohertz by 1,000:
2780 (kHz) ÷ 1000 = 2.780 MHz
To convert MHz to meters, divide 300 by the number of megahertz:
300 ÷ 7.1 MHz = 42.25 meters
