Using Standard AC Power
To power the scanner from an AC out-
let, you need an AC adapter (not sup-
plied) with a 5.5 mm outer diameter/
2.1 mm inner diameter tip.
Cautions:
You must use a Class 2
power source that sup-
plies 12V DC and deliv-
ers at least 500 mA. Its center tip
must be set to positive and its
plug must fit the scanners 
DC
13.8V 
jack. Using an adapter that
does not meet these specifica-
tions 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, dis-
connect the adapter from AC pow-
er before you disconnect it from
the scanner.
1. Connect the adapters 5.5 mm
outer diameter/2.1 mm inner
diameter tip to the adapters cord
and set the barrel plugs tip to pos-
itive.
2. Insert the adapters barrel plug
into the 
DC 13.8V jack on the back
of the scanner.3. Plug the adapter into a standard
AC outlet.
CONNECTING AN 
EXTENSION SPEAKER
In a noisy area, an amplified extension
speaker (available at your local Ra-
dioShack 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 
EXT SP
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 
EXT SP jack
on the back of the scanner. (Your local
RadioShack store carries a wide se-
lection of earphones and head-
phones). This automatically dis-
connects 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 per-
manent hearing loss.
•Set 
VOLUME to the lowest setting
before you begin listening. After
you begin listening, adjust 
VOL-
UME
 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.
CONNECTING THE CLONE 
CABLE
You can transfer the programmed
data to and from another Cat. No. 20-
196 or Cat. No. 20-522 scanner using
the supplied clone cable. Connect the
cable between each scanner’s 
PC/IF
jacks. See “Cloning Programmed
Data from Scanner to Scanner” on
Page 35. You can also upload or
download the programmed data to or
from a PC using an optional PC inter-
face kit available through your local
RadioShack store.

							13 Once you understand a few simple terms used in this manual and familiarize your-
self with your scanner’s features, you can put the scanner to work for you. You sim-
ply 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 fre-
quencies 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 KEYPAD
Your scanner’s keys might seem confusing at first, but this information should help
you understand each key’s function.
Note: 
Some of the scanner’s keys perform more than one function and are marked
with more than one label. The steps in this Owner’s Manual show only the label on
the key appropriate to the action being performed.
SCAN — scans through the programmed channels or ID code.
WX — scans through the 7 preprogrammed weather channels.
AT T (attenuate)
 — turns attenuation on to reduce the scanner’s sensitivity, or turns
it off to increase it.

UNDERSTANDING 
BANKS
Channel Storage Banks
To make it easier to identify and select
the channels you want to listen to,
channels are divided into 10 banks
(0–9) of 50 channels (00 to 49) each.
Use each channel-storage bank to
group frequencies, such as those
used by the police department, fire de-
partment, ambulance services, or air-
craft (see “Guide to the Action Bands”
on Page 45). For example, the police
department might use four frequen-
cies, one for each side of town. You
could program the police frequencies
starting with 000 (the 1st channel in
bank 0) and program the fire depart-
ment frequencies starting with 100
(the 1st channel in bank 1). The first
digit identifies the bank (0–9). The
second and third digits identify the
channel within the bank (00–49).
Search Banks
This scanner is able to search 10
search banks. You can also replace a
bank with one of the preprogrammed
service bands. (For the default setting,
see “Searching a Preprogrammed
Frequency Range” on Page 25).
UNDERSTANDING 
CTCSS/DCS
Continuous Tone Coded Squelch Sys-
tem (CTCSS) and Digital Coded
Squelch (DCS) are two methods used
to prevent interference by other radio
communications. Your scanner can
receive transmissions that use these
codes.
When your scanner receives a CTC-
SS transmission, 
PL (private line) ap-
pears. When your scanner receives a
DCS transmission, 
DPL (digital private
line) and a 3-digit code appear.
PL Codes
PL codes are low-frequency audio
tones that are used to differentiate dif-
ferent users on the same channel. PL
codes appear according to the EIA
standard CTCSS tones, and range
from 67.0 Hz to 254.1 Hz. PL codes
are displayed directly as a frequency.
DPL Codes
DPL codes are similar to PL codes,
except they might be transmitted as
either tones or digital codes. Although
there are as many as 4096 DPL
codes, only about 100 are actually
used.
DPL codes appear in the format
Dxxx, where xxx is an octal code.

UNDERSTANDING YOUR 
SCANNER’S MODES
Open and Closed Modes
You can set your scanner to change
the way it receives signals. These set-
tings, called 
open mode and closed
mode
, affect how the scanner re-
ceives signals from communications
systems that use some type of closed
squelch (such as PL, DPL, LTR, MOT,
and ED systems). You can set each of
the scanner’s channel storage banks
to open or closed mode.
In open mode, the scanner scans sig-
nals transmitted in all systems. In
closed mode, the scanner scans sig-
nals transmitted only under the follow-
ing conditions:
• When the signals are in the FM
mode.
• When the signals are in the LT,
MO, or ED mode 
and the signals
ID code matches the programmed
ID code.
• When the signals are in the PL or
DPL mode 
and the signals ID
code matches the programmed ID
code.
Note:
 When the signals are in the
PL or DPL mode, the scanner
receives all signals on a channel
when the ID code is set to NONE.
You can also select the users or talk
groups you want the scanner to re-
ceive in closed mode.When you set a channel storage bank
to open mode, 
+ (open) appears un-
der the bank’s number while scanning.
When you set a channel storage bank
to closed mode, 
– (closed) appear un-
der the channel storage banks num-
ber while scanning. Or, 
OPEN or
CLOSED appears while the scanner is
in manual mode or while the scanner
is receiving a signal during scanning.
See “Changing the Open/Closed
Mode” on Page 32 for more informa-
tion about setting the open and closed
modes.
LTR (E. F. Johnson) Mode
You can set your scanner so it de-
codes the talk group IDs used with
LTR systems. This setting is called the
LTR mode.
LTR systems are trunking systems
used primarily by business or private
communications service providers,
such as taxicabs, delivery trucks, and
repair services. These systems en-
code all trunking information as digital
subaudible data that accompanies
each transmission. Users on an LTR
system are assigned to specific talk
groups, which are identified by the ra-
dio as six-digit numbers. These num-
bers are in the form 
AHHUUU, where:
A = Area code (0 or 1)
H = Home repeater (01 through 20)
U = User ID (000 through 254)

							20
When the scanner receives a trans-
mission on a channel set to the LTR
mode, it first decodes the LTR data in-
cluded with the transmission. In the
open mode, the scanner stops on the
transmission and displays the talk
group ID on the bottom line of the dis-
play. In the closed mode, the scanner
only stops on the transmission if the
LTR data matches a talk group ID that
you have stored in the bank’s talk
group ID list and have not locked out.
LTR systems are frequently pro-
grammed so that each radio has a
unique ID code.
Motorola Mode
You can set your scanner so it de-
codes the talk group IDs used with
Motorola trunking systems. This set-
ting is called the 
Motorola mode.
Motorola systems are trunking sys-
tems used primarily by business and
public safety groups to efficiently allo-
cate a small number of frequencies
(as few as 5) to many groups of users
(as many as several thousand). To do
this, each group of users in the system
is assigned to a specific talk group.
For example, the east side patrol offic-
ers might all be assigned to talk group
2160. One channel in the system is
continuously transmitting data that
identifies which talk groups are active
on which channel. In addition, this talk
group information is also transmitted
as subaudible data on each active
channel.When the scanner receives a trans-
mission on a channel set to the Motor-
ola mode, it first decodes the talk
group ID data included with the trans-
mission. In the open mode, the scan-
ner stops on the transmission and
displays the talk group ID on the bot-
tom line of the display. In the closed
mode, the scanner only stops on the
transmission if the talk group ID
matches a talk group ID that you have
stored in the bank’s talk group ID list
and have not locked out.
Motorola trunking systems come in
three categories: 
Type I, Type II, and
Type I/II Hybrid. Each category dis-
plays and uses talk group IDs in slight-
ly different ways.
Motorola Type I IDs are in the form
FFF-SS, where:
FFF = Fleet ID
SS = Subfleet ID
Type I systems are usually organized
with different user groups assigned to
different fleets. For example, a valid
fleet/subfleet ID identifying all detec-
tives within a police department might
be 
000-12, where 000 identifies all
police users and 
12 identifies the De-
tective division.
To properly map the raw Type I data
to the correct fleet-subfleet format,
you must program the correct fleet
map into the scanner. Fleet map infor-
mation is widely available on the Inter-
net for most Type I systems in use.
