RadioShack Pro 2067 Trunk Track Scanner Owners Manual

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...

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-

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...

14
STEP — changes the frequency step or displays the step frequency during a
search.
MODE — changes the receive mode.
PRI (priority)
 — sets and turns the priority function on or off.
TEXT — lets you input text.
TUNE — tunes a frequency along with s 
or t
.
SEARCH — lets you search the ten search banks.
MAN — stops scanning and lets you directly enter a channel number.
FUNC — lets you access various functions by pressing this key along with other
keys.

15
• — enters a decimal point (necessary when programming frequencies), space, or
hyphen (in Motorola type I code setting).
ENTER —enters frequencies, text, and so on.
TRUNK — stores the trunking ID code or holds the trunking ID while scanning.
L/OUT (lockout)
 — lets you lock out a selected channel, skip a specified frequency
during search, or lock out a selected ID code.
CLEAR — clears an incorrect entry.
PROG (program) 
— programs frequencies into channels.

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...

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...

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...
