INTRODUCTlON
Your new HadloShack PRO-79 200-Channel Portable Scanner lets you in on all the action.
This scanner gives you direct access to over 25,000 excitmg frequencres, including police
and fire departments, ambulance SeNlCeS, and amateur radio services, You can select up to
200 channels to scan. and you can change your selection at any time.
The secret to your scanner’s ability to scan so many lrequenctes is its customdesigned
mlcroprocessor~ a tiny, built-in computer. Your scanner also has these special features:
Four Sen/ice Banks — let you search preset frequencies in separate fire/police, air, ham
radio, and marine banks. to make lt easy to locate specific types of calls.
Two-Second Scan Deley— delays scanning for 2 seconds before movrng to another channel,
so you can hear more replies.
Ten Channel-Storage Banks — you can store up to 20 channels in each oi 10 different banks,
to group channels so you can more easily identify calls.
20 Monitor Memories — let you temporarily save up to 20 frequencies you locate during a
search, so you can move selected trequencres to channel storage later.
Memory Backup — keeps the channel frequencies stored In memory {or about 1 hour during
a power loss.
HeperSearch TM and HyperScan TM — let you set the scanner to search at up to 50 steps
per second and scan at up to 25 channels per second, to help you quickly find interesting
broadcasts
Duplicate Frequency Check — automatically notifies you if you are about to store a frequency
you have already stored. to help avoid wasting storage space.
Direct Search _ lets you search for new and unlisted frequencies starting lrorn a specified
frequency.

SCANNING LEGALLY
Scanning is a fun and interesting hobby. You can hear police and fire departments,
ambulance services, government agencies, private companies, amateur radio services,
aircraft, and military operations. It is legal to listen to almost every transmission your
scanner can receive. However, there are some electronic and wire communications that are
illegal to intentionally intercept. These include:
. telephone conversations (cellular, cordless, or other private means of telephone Signal
transmission)
. pager transmissions.
. scrambled or encrypted transmissions
According to the Federal Electronic Communications Privacy/Act (ECPA), as amended, you
could be fined and possible imprisoned tor intentionally listening to, using, or disclosing the
contents of such a transmisSion unless you have the consent of a party to the
communication (unless such activity is otherwise illegal). These laws change from time to
time and there might be state or iocal laws that also affect legal scanner usage.

automatically disconnects the internal speaker.
add illustration.
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 the volume to the lowest setting before you begin listening, After you begin listening.
adjust the volume to a comfortable level.
. 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 discomtort might still damage your hearing.
Traffic Safety
Do not wear an earphone or headphones while you drive a vehicle or ride a bicycle. This can
create a traffic hazard and can be illegal in some areas.
Even though some earphones and headphones let you hear some outside sounds when
you listen at normal levels, they still can present a traffic hazard.

UNDERSTANDiNG THE PRO~79
Once you understand a few simple terms used in this manual and familiarlze 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
frequencres, you can use the search tunction.
You can also search the sewioe-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 channslvslorage bank. You can then
scan the channelstorage banks to see it there is activity on the frequenmes stored there.
Each time the scanner finds an active frequency, it stays on that channel until the
transmission ends.

Channel—Storage Banks
To make it easier to identify and select the channsts you want to listen to, channels are
divided into 10 banks of 20 channels each. Use each channel-storage bank to group
frequenmes, such 5 those used by the police department, fire department, ambulance
sen/ices, or aircraft (see “Gurde to the Action Bands” on Page XX). For example, the police
department might use four frequencies, on for each side of town. You could program the
police frequencies starting wrth Channel 1 (the first channel in bank 1] and program the fire
department frequencies starting with Channel 21 (the first channel in bank 2).

Birdie Frequencies
Every scanner has birdie frequencies — signats created inside the scanners receiver, which
might interfere with broadcasts on the same frequencies. If you program one of these
frequenCies. you hear only noise on that trequency. lt the interference is not severe, you
might be able to turn SOUELCH clockwise lo cut out the birdie.
To find the birdies in your scanner:
Disconnect the antenna and move it away from the receiver. Make sure that no other
nearby radio or TV sets are turned on near the scanner.
. Search in each frequency band from its lowest lrequency to the highest. Occasionally, the
searching will stop as it it had iound a signal, often without any sound. That is a birdie.
. Make a list at all the birdies in your particular scanner for future relerenoe.

AVOIDlNG IMAGE FREQUENCIES
You might discover one of your regular stations on another frequency that is not listed. ll
might be what is known as an image frequency. For example. you might lind a sen/toe that
regularly uses a frequency 01453275 also on 474.675.
To see if it 15 an image, do a little math.
Note the new lrequency. 474 675
Double the intermediate frequency of 10.? MHz
(21.400)
and subtract it from the new frequency. 41.400
if the answer is the regular frequency, 453.275
then you have tuned to an 1mage.
Occasionally, you might get interference on a weak or distant channel from a strong
broadcast 21.4 MHz above or below the tuned frequency. This is rare, and the image signal
is usually cleared whenever there lS a broadcast on the actual frequency.

20314 Owner’s Manual Draft
FREOU EN CV CONVERSION
The tuning beation of a station can be expressed in 1requency {kHz or MHz) or in
wavelength (meters). The following inlormation can help you make the necessary
conversions
1 MHz (rmllion) = 1000 kHz (lhousand)
To convert MHz to kHz, multrply 1he number of MHz by 1,000:
30.62 MHZ X 1000 - 30,620 kHz
To conven from kHz to MHz, divide the number of kHz by 1000.
1271800 kHzI1000 2127.8 MHZ
To conven MHz to melers, diwde 300 by the number of MHz‘
300 I 50 MHz = 6 meters
