step 1: installing your scanner  
You can mount your scanner as a base station or in your vehicle. If  
you are unsure how to install your scanner in your vehicle, consult  
your automobile manufacturer, dealer, or a qualied installer.  
base station  
Attach the four protective rubber feet to the mounting bracket  
when you use the scanner as a base station on a at surface such  
as a desk, shelf, or table. Because the speaker is on the bottom  
of the scanner, you can use the mounting bracket to elevate your  
scanner off the surface for better sound.  
vehicle m ounting  
To mount your scanner under or over the dashboard, use the  
mounting bracket. Before installing, conrm that your scanner  
ts in the desired mounting area and you have all the necessary  
materials to complete the task.  
IMPORTANT: AVOID AIRBAG DEPLOYMENT ZONES. This can  
prevent the airbag from performing properly and result in injury.  
1. Use the supplied mounting bracket as a template to mark  
positions for the two mounting screws.  
2. At the marked positions, drill holes slightly smaller than the  
screws. When drilling holes, be sure to avoid obstructions and  
wires behind the mounting surface.  
3. Attach the mounting bracket to the surface using the supplied  
screws.  
4. Slide the scanner into the bracket, aligning the scanner’s holes  
with the holes in the bracket, and then screw the mounting  
knobs into the scanner.

Quick Start  
Your scanner requires a 2 x 7-1/8 x 5-5/16 inch (50 x 180 x 135  
mm) mounting area. Allow an additional 2-3/8 inch (60 mm) space  
behind the scanner for connectors and wires.  
1. Remove the four rear screws that secure the outer metal case  
and pull off the case with care.  
2. Insert the DIN sleeve into the opening in your dashboard, lip  
facing out.  
3. Push out the top and bottom tabs to hold the sleeve rmly in  
place.  
4. Slowly slide the scanner into the sleeve until it locks in place.  
When mounting in your dashboard, you will need to  
connect an external antenna and an external speaker.  
To remove your scanner from the DIN sleeve, insert the  
two removal keys straight into the scanners front panel  
and pull the scanner out.  
NOTES  
step 2: pow er your scanner  
You can power your scanner from a wall outlet, through your  
vehicle’s ignition, or from your vehicle’s cigarette lighter or power  
port. You must use a Class 2 power source that supplies 12V DC  
and delivers at least 500mA. Its center tip must be set to positive  
and its plug must t the scanner’s DC 12V jack. Using an adapter  
that does not meet these specications could damage the scanner  
or the adapter.

The antenna should be as high  
as possible and vertical for best  
performance.  
NOTES  
Keep the antenna and cable as far as possible from  
sources of electrical noise, such as appliances or other  
radios.  
Always use 50-ohm coaxial cable, such as RG-58 or RG-8, to  
connect an outdoor antenna. For lengths over 50 feet, use RG-8  
low-loss dielectric coaxial cable. You also may need a BNC adapter  
(not supplied).  
external speaker  
To use an external speaker (available at your local RadioShack  
store), plug the speaker’s 1/8 inch (3.5 mm) plug into the scanner’s  
EXT SP jack.  
Connecting an external speaker mutes the scanners  
internal speaker.  
NOTE  
CAUTION: Use extreme caution when installing or removing  
an outdoor antenna. If the antenna starts to fall, let it go! If the

earphones / headphones  
For private listening, you can plug earphones or headphones into  
your scanner’s headphone jack. Do not use headphones with your  
scanner when operating a motor vehicle in or near trafc. Doing so  
can create a trafc hazard and could be illegal in some areas. Some  
headphones let you hear some outside sounds when listening at  
normal volume levels, but they still can present a trafc hazard.  
To protect your hearing, follow these guidelines for 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,  
then adjust the volume to a comfortable level.  
After 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 discomfort might still damage your hearing.

The Basics  
the basics  
A frequency is the tuning location of a station. A channel is a  
programmable memory location for storing frequencies that  
you can scan for activity. Channels are grouped into 10 channel-  
storage banks, each of which contains 100-channels. Service banks  
are preset channel-storage banks of frequencies used by HAM  
operators, marine, aircraft, and police (re/emergency) services.  
For example, many amateur radio frequencies are located in the  
HAM service bank.  
Your scanner provides many features that help you locate,  
monitor, and organize useful transmissions in your area, including  
frequencies used by police and re departments, ambulance  
services, government agencies, private companies, amateur  
radio services, military operations, pager services, and wireline  
(telephone and telegraph) service providers.  
This scanner is designed to prevent reception of illegal  
transmissions, in compliance with laws that require that scanners  
be manufactured to not be easily modiable to pick up those  
transmissions. Do not open your scanner’s case to make any  
modications that could allow it to pick up transmissions that it is  
not legal to listen to. Doing so could subject you to legal penalties.  
It is legal to listen to almost 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 private  
means of telephone signal transmission)  
pager transmissions  
any scrambled or encrypted transmissions  
According to the Electronic Communications Privacy Act (ECPA),  
as amended, you are subject to nes and possible imprisonment  
for intentionally listening to, using, or divulging the contents of  
such a transmission unless you have the consent of a party to the  
communication (unless such activity is otherwise illegal).  
We encourage responsible, legal scanner use.

Skyw arn  
Skywarn jumps directly to the last channel in memory from any  
mode. The scanner pauses any active scans and starts receiving  
transmissions in the last channel. If no frequency is programmed in  
the last channel, No Prog appears and the scanner sounds an error  
tone.  
During inclement weather, reports made by Skywarn observers  
include information about:  
pea-sized and larger hail  
wind and wind gusts 40 MPH and greater  
heavy rainfall  
lightning (cloud-to-cloud and especially cloud-to-ground)  
wall clouds (which can spawn tornadoes)  
severe lowering of a wall cloud  
turbulence in a wall cloud  
funnel clouds  
tornadoes  
high water areas  
downed power lines  
other emergency conditions that affect life or property  
Skywarn broadcasts can help you prepare for inclement weather  
conditions in your immediate area, even before your local NOAA  
weather broadcast and local TV or radio station can announce  
them. Enter the local Skywarn frequency for your area into Channel  
1000 on your scanner. Then, listen to Skywarn rst when severe  
weather threatens. Listen to NOAA for weather alerts and warnings,  
watch box notices, and weather-forecasts. Listen to Skywarn to  
hear trained observers in your vicinity call in ofcial reports to a  
net control station which relays those reports to NOAA and other  
emergency agencies.  
If you tune to a Skywarn frequency when the Skywarn  
net is not active, you may hear nothing, or you may  
hear amateur radio operators talking on a local repeater  
system.

Beyond the Basics  
Signal Stalker I  
Signal Stalker I searches for frequencies in a specied range.  
This works well for locating strong local transmissions, such as  
mobile and handheld two way radios in areas with no other strong  
transmission sources; however, if you are in an area with many  
transmission sources (such as pager radio transmitters, multiuse  
radio towers, trafc control devices, etc.), Signal Stalker I may not  
correctly display.  
Signal Stalker I can work in the background while scanning other  
frequencies and automatically saves strong signals to one of 10  
log channels, located after Channel 1000. You can scan the log  
channels along with the normal channels, or you can manually  
access log channels as Channel 1001, Channel 1002, ... Channel  
1010. “-1-”, “-2-”, ... “-10-” appear as channel numbers.  
Turn off the data skip feature if it is on.  
NOTES You cannot program frequencies in the log channels.

Trunking Operations  
trunking operations  
The scanner can track transmissions for up to 10 Motorola Type I,  
Type II, hybrid, EDACS or LTR analog trunking systems. When the  
scanner nishes checking activity in the trunked system, it scans  
other conventional frequencies in the bank.  
For trunked reception, set the squelch at the center position. If set  
too high, it could prevent your scanner from locking on the control  
channel reliably. If it is set too low, it can delay nding the control  
channel. The best setting is critical for monitoring trunked systems.  
program m ing trunked frequencies  
To program trunked frequencies, complete the following steps:  
1. Press E/ PGM in conventional mode to set the scanner in  
programming mode. Then, press TRUNK. Your scanner beeps,  
then all the bank numbers ash.  
2. Press the number key for the desired target storage bank.

data channel is acquired, the scanner begins a trunk search that  
nds all active talk groups in the trunked system.  
8. (Optional) To turn a bank on or off, press and hold the SCAN/  
MANUAL button during trunk scanning. When the trunked bank  
appears, press the bank number (0–9).  
talk group ID  
Each trunk scanning bank contains ten talk group ID lists (with up to  
10 talk group IDs each), for a total of 100 talk group IDs each. These  
lists organize trunking system users into categories. For example,  
you might use List 1 for police IDs, List 2 for re department IDs,  
and List 3 for emergency medical service IDs. After you store talk  
group IDs in a list, you can scan them just as you scan conventional  
channels.  
To locate talk group ID lists for your local police, re, or  
other agencies, refer to frequency guides available at your

Press SCAN/ MANUAL to begin scanning the lists you have stored.  
If an ID is incorrect, Error ashes twice and the scanner beeps  
several times, then the scan list numbers appear at the top of the  
display. To correct the entry, delete the incorrect ID.  
One of the ten scan lists must always be active. You  
cannot remove all of them.  
NOTE  
To remove a scan list from active scanning, use the number keys to  
enter the scan list’s number. The scan list number turns off, and the  
IDs in that list are not scanned.  
To restore a scan list to active scanning, use the number keys to  
enter the number of the list again.  
locking out a talk group ID  
Many municipal and commercial services use trunk systems to  
transmit signals from devices such as water-meter transmitters,  
door alarms, and trafc signals. These are not voice signals, but are  
assigned talk group IDs. To scan more efciently, you can lock out  
up to 100 talk group IDs.  
To lock out an ID, press L/ O when the ID appears. The ID is locked  
out, and the next active ID appears. If you lock out an ID while  
searching, it is also locked out of the scan list(s).

press . The frequency ashes twice. Then hold down until a  
conrmation tone sounds and the ID and the frequency alternate.  
To return to normal operation, press .  
type I and hybrid trunked system s  
Your scanner is preset to scan Type II system IDs. When you scan  
trunked frequencies, each Type II user ID appears as an even  
number without a dash (example 2160). Your scanner can also scan  
Type I trunked systems. Each Type I ID appears as a three- or four-  
digit number, followed by a hyphen, followed by a one- or two-digit  
number (example 200-14).  
If you notice a mix of odd- and even-user IDs (examples  
6477, 2160, 6481, 6144, and 1167), then you are  
probably monitoring either a Type I or hybrid (a  
combination of Type I and Type II user IDs) system with  
the S-Bit function turned off.  
NOTES  
If you consistently miss responses even with scan  
delay, change your default system type or eet map.
