External Power

You can power your scanner using a 9V, 400mA AC/DC adaptor and size C adaptaplugTM (neither supplied).

To use an external power source:

1. Always connect the adapter

(not supplied) to the

scanner rst.

2. Plug the adapter into the

power source.

3. To disconnect, unplug the

adapter from the power

source rst.

If you use an external power source for regular operation, install alkaline batteries for emergencies. Rechargeable batteries will self- discharge, even when not used, and could have no usable power.

Caution: You must use a Class 2 power source that supplies 9V DC and delivers at least 400 mA. Its center tip must be set to positive and its plug must t the scanner’s PWR DC 9V jack. Using an adaptor that does not meet these

specications could damage the scanner or the

adaptor.

Headphones and Speakers

You can plug headphones or an amplied

speaker (neither included) into your scanner’s headphone jack. This automatically mutes the scanner’s speaker.

Even though some earphones/headphones let you hear some outside sounds when listening at normal volume levels, they still can present a

trafc hazard.

To protect your hearing, follow these earphone or headphones guidelines:

POWER DC 9V — External power source (not included).

Headphones and Speakers

You can plug headphones or an amplied

speaker (neither included) into your scanner’s headphone jack. This automatically mutes the scanner’s speaker.

Even though some earphones/headphones let you hear some outside sounds when listening at normal volume levels, they still can present a

trafc hazard.

To protect your hearing, follow these earphone or headphones guidelines:

• 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

listening. Turn on the scanner, and 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.

Trunking Setup

Trunking Modes

In Closed mode, the scanner stops only on transmissions with saved and unlocked Talk Group IDs. This lets you focus a scan on the

frequencies you have identied, ignoring other

transmissions.

In Open mode, the scanner stops for transmissions on any unlocked channel. This lets you search for Talk Group IDs that you can then save.

Instead of transmitting on a specic frequency,

trunking systems choose one of several frequencies during a 2-way radio transmission and simultaneously transmit a Talk Group ID

that identies the 2-way radio user. This allows

trunking systems to allocate fewer frequencies to multiple 2-way radio users.

Dening a Trunking Bank

You can dene any of the 10 banks as a trunking

bank, but each bank can only scan for one system: Motorola, EDACS (GE/Ericsson), or LTR (EF Johnson).

Trunking banks can contain both trunking and non-trunking channels.

EDACS Trunking Setup

Group ID data on a dedicated control channel. Scanning requires clear reception of the control channel at all times, so EDACS systems generally have a smaller usable area. You can manually select the data channel, but an external antenna can greatly improve EDACS scanning. If you are programming frequencies for an EDACS sysstem, you must store them in the Logical Channel Number order (usually listed as LCN#).

LTR Trunking Setup

LTR systems, assign each frequency a Home Repeater (HR) number, and are frequently programmed with unique ID codes for each radio. LTR Talk Group IDs are organized in a

Saving Trunking Channels

Trunking channels are dened using the

same procedure for non-trunking channels. In each bank, you can mix channel modes, including conventional, but you can scan only one trunking mode at a time, either EDACS, Motorola, or LTR.

Trunk Scanning

In each bank, you can mix conventional channels and frequencies in a bank. However, you can scan only one trunking mode at a time, either EDACS, Motorola, or LTR.

To focus on trunk scanning, during a normal scan, you turn off banks that contain only conventional channels.

For Motorola channels, your scanner displays the Talk Group ID memory location, received frequency, voice channel (VC), and the Motorola ID number.

To change the scanning direction, press  or .

Because Motorola control frequencies change daily, you should save all the control frequencies in the same bank. If you do not know the control frequency, save all the Motorola frequencies in the same bank.

EDACS frequencies are assigned Logical Channel Numbers (LCN) and organized in a

specic order. To scan correctly, you must

program the frequencies in LCN order, starting with Memory 01.

Trunked modes (MO, ED, and LT) can only be selected for frequencies above 137 MHz that use trunking operations.

For information about adding text tags to a channel, see “Text Tags” on Page 44.

Trunk Scanning

In each bank, you can mix conventional channels and frequencies in a bank. However, you can scan only one trunking mode at a time, either EDACS, Motorola, or LTR.

To focus on trunk scanning, during a normal scan, you turn off banks that contain only conventional channels.

For Motorola channels, your scanner displays the Talk Group ID memory location, received frequency, voice channel (VC), and the Motorola ID number.

To change the scanning direction, press  or .

Your scanner automatically mutes the audio while it decodes control channel data. However, we recommend you turn SQ clockwise and leave it set to a point just after the hiss stops. This lets the scanner quickly acquire the data channel.

For Motorola trunking systems, more than one talk group can transmit at a time. If you manually tune the scanner, you will hear the talk group on that channel, but the display will alternate between all active Talk Group IDs.

For EDACS and Motorola (above 406 MHz range), the scanner monitors the control channel between each transmission to identify talk groups. For some Motorola (under 512 MHz range) and LTR systems, the scanner uses the subaudible data sent with each transmission to identify talk groups.

Troubleshooting

Problem Solution

The scanner is not working at all.

Cause:

The AC or DC adaptor might not be connected.

Be sure the adaptor’s barrel plug is fully inserted into the PWR DC 9V jack. The center tip of the adaptor’s barrel plug must be set to positive.

The batteries might be dead or need to be recharged.

If the scanner does not operate when you connect a DC adaptor, the DC adaptor socket might be dirty.

Recharge the rechargeable batteries or replace the standard batteries.

Unplug the DC adaptor from the power source and clean the socket, or check the adaptor’s internal fuse.

Problem Solution

The scanner does not receive any stations or reception is poor.

Cause:

Antenna might not be connected correctly.

Squelch setting might be too sensitive causing it to pick up unwanted, partial or weak transmissions.

Antenuator might be on so your scanner might not receive weak signals.

The scanner might need to be initialized.

The scanner is on but does not scan.

Cause:

The squelch might not be adjusted correctly.

Check the antenna.

Check the squelch.

Check the Attenuator.

Turn the scanner off then on again, or initialize the scanner.

Turn SQ clockwise.

Save more frequencies into channels.

Turn off keylock.

There might only be one channel or no channels stored in the scanner.

The keylock might be turned on.

Problem Solution

Error message appears when trying to upload or download from a computer.

Cause:

Your computer is using Windows XP and does not have the necessary USB cable driver.

Download and install the “Windows XP Driver to resolve PC

connection error” le

from your scanner’s

Product Support page or the Software Download page on www.RadioShack.com.

Then make your connection and try again. Be sure the correct COM port is selected in device manager.

Birdie Frequencies

All scanners have signals created inside the scanner’s receiver. These birdie frequencies can interfere with transmissions on the same frequencies. If the interference is not severe, you might be able to turn SQ clockwise to omit the birdie.

Initializing the Scanner

If the scanner’s display locks up or does not work properly after you connect a power source or install batteries, you might need to initialize it.

Caution: This procedure clears the scanner’s memory. Initialize the scanner only after trying all other methods to correct issues.

To initialize the scanner:

1. Turn off the scanner, then turn it on again.

2. While “Multi-system Trunking Scanner”

3. Press 1.

4. Press ENT. “Initializing please stand by”

To nd the birdies:

1. Disconnect the antenna and moving it away from the scanner. Make sure that no other nearby radio or TV sets are turned on near the scanner.

2. Start a search of every frequency range from its lowest frequency to the highest. When the search stops, often without any sound, this is a birdie.

3. Make a list of all the birdies in your scanner for future reference.

Service and Repair

If your scanner is not performing as it should, take it to your local RadioShack store for assistance. To locate your nearest RadioShack, use the store locator feature on RadioShack’s web site (www.radioshack.com), or call 1- 800-The Shack (800-843-7422) and follow the menu options.

Scanning Legally

Your scanner covers frequencies used by

many different groups including police and re

departments, ambulance services, government agencies, private companies, amateur radio services, military operations, pager services, and wireline (telephone and telegraph) service providers. 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). This scanner is designed to prevent reception of illegal transmissions, in compliance with the law which requires that scanners be manufactured

in such a way as to not be easily modiable to

pick up those transmissions. Do not open your

scanner’s case to make any modications that

could allow it to pick up transmissions that it is not legal to listen to. Doing so could subject you to legal penalties. In some areas, mobile use of this scanner is unlawful or requires a permit. Check the laws in your area. It is also illegal in many areas to

interfere with the duties of public safety ofcials

by traveling to the scene of an incident without authorization. We encourage responsible, legal scanner use.

Appendix A: Glossary

Frequency – The signal (expressed in MHz)

used by broadcasting radios. To nd active

frequencies, you can use frequency guides available from your local RadioShack store, frequency lists posted on the Internet, or your scanner’s search function.

Bank – A storage unit for a group of channels. A channel contains one frequency, and a bank can hold up to 100 channels.

Channel – A programmable memory locations for a single frequency.

Talk Group ID – A simultaneous trunking

transmission that identies 2-way radio users.

This allows trunking systems to allocate a few frequencies to multiple 2-way radio users.

Sub-bank – Each bank has an associated Talk Group ID sub-bank. In Closed mode, the scanner only stops if a transmission has a Talk Group ID saved in the associated Talk Group ID sub-bank. In Open Mode, the scanner stops on all transmissions, except those you lock out.

Appendix B: Search Banks

Note: All scanners tune by steps. Your RadioShack scanner uses steps consistent with the latest US or worldwide standards. If you enter a non-valid step frequency, any scanner will tune to the next step. Some scanner designs do this without showing the correct step in the display. This scanner will show the actual tuned frequency in the display. Because steps are so close together, the audio quality will not be affected by the offset.

Note: Some Marine frequencies assing two frequencies to one channel. For example, 157.000 and 161.600 are assigned in Channel 20. Search bank: SR1 CB band Receive mode: AM
