Connecting the Antenna

Attach the supplied antenna to the scanner by aligning the slots around its base with the tabs on the scanner, and then slide into place.

When using an external antenna, always connect with 50-ohm, RG-58, or RG-8, coaxial cable. If the antenna is over 50 feet from the scanner, use RG-8 low-loss dielectric coaxial cable. If your antenna’s cable does not have a BNC connector, your local RadioShack store carries a variety of BNC adapters.

Attaching the Belt Clip

Use a Phillips-head screwdriver and the supplied screws to attach the clip to the scanner.

Powering Your Scanner

You can power your scanner with batteries, DC adapter, or AC adapter.

Batteries

1. Remove the battery compartment cover.

2. Set the Battery Switch inside the battery compartment to the appropriate setting:

• ALKALINE when using alkaline batteries.

• Ni-MH when using rechargeable (Ni-MH) AA batteries.

Scanner Setup

3. Insert two AA batteries (not included) into the battery compartment and two AA batteries into the battery compartment cover, matching the polarity symbols (+ and -) marked inside.

4. Replace the cover.

Warning: Only set the Battery Switch to Ni-MH

for use with nickel metal hydride (Ni-MH) rechargeable batteries.

Never use non-rechargeable batteries when the switch is set to Ni-MH.

To charge batteries:

1. Set the Power Switch to Ni-MH.

2. Install rechargeable batteries.

3. Connect an external power source to the DC 9V 300mA jack.

The scanner stops charging automatically after a maximum of 14 hours.

Warning: Do not attempt to charge batteries if non-rechargeable batteries are installed in the scanner and the switch is set to Ni-MH, or if you are unsure of the switch’s position. Nonrechargeable batteries will get hot and can explode if you try to recharge them.

Battery Switch

Scanner Setup

Battery Notes

• When battery power is low,

ﬂashes and the scanner beeps every 15 seconds. When battery power is depleted, the scanner turns itself off.

• Rechargeable batteries last longer and deliver more power if you let them fully discharge once a month. To do this, use the scanner until

ﬂashes.

• Use only fresh batteries of the required size and recommended type. Do not mix old and new batteries, different types (alkaline or rechargeable), or rechargeable batteries of different capacities.

• Remove old or weak batteries. If you will not use the scanner with batteries for a month, remove the batteries. Batteries can leak chemicals that destroy electronic circuits.

• Always dispose of old batteries promptly and properly. Do not bury or burn them.

Recycle Rechargeable Batteries

Placing rechargeable batteries in the

trash can be harmful to the environment. Instead, recycle old rechargeable batteries at your local RadioShack store free of charge. RadioShack participates in the RBRC© battery recycling program, and is committed to preserving the environment and conserving natural resources. Call 1-800-THE-SHACK (1-800-843-7422) for more information.

External Power

You can power your scanner using an external power source that supplies 9V DC and delivers at least 300mA. Its center tip must be set to positive and its plug must ﬁt the scanner’s DC 9V 300mA

Scanner Setup

jack. You can use an “Adaptaplug C” for AC adapters. Using an adapter that does not meet these speciﬁcations could damage the scanner or the adapter.

To use an external power source:

1. Always connect the adapter (not supplied) to the scanner ﬁrst.

2. Plug the adapter into the power source.

3. To disconnect, unplug the adapter from the power source ﬁrst.

Warning:

Do not connect a charging adapter to the scanner if nonrechargeable batteries (such as alkaline batteries) are installed in the scanner and the switch is set to Ni-MH, or if you are unsure of the switch’s position.

Turning on the Scanner

1. Turn SQUELCH fully counterclockwise.

2. Turn VOLUME/OFF clockwise until it clicks and you hear a hissing sound.

3. Turn SQUELCH clockwise until the hissing stops.

Note: Make sure the scanner’s antenna is connected before you turn it on.

To perform a quick check of scanner operation, press the WX / key. If you are near a NOAA weather station, you should hear weather information.

POWER DC 9V

Scanner Setup

Connecting Headphones

For private listening, you can plug headphones (not included) into the headphone jack on top of your scanner. This automatically disconnects the internal speaker. Note that the sound is not in stereo.

Listening Safely

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.

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

Understanding Your Scanner

We use a few simple terms in this manual to explain the features of the scanner. Familiarize yourself with these terms and the scanner’s features, and you can put the scanner to work for you right away.

The scanner scans conventional frequencies and trunked systems. A frequency, expressed in kHz or MHz, is the tuning location of a station. To ﬁnd active frequencies, use the search function. For more information about trunked transmissions see “Trunk Operation” on p. 46.

Scanner Setup

Besides searching within a selected frequency range, you can also search your scanner’s service banks. Service banks are preset groups of frequencies categorized by type of service. For example, many amateur radio frequencies are located in the Ham service bank.

When you search and ﬁnd a desired frequency, you can store it into a programmable memory location called a channel. Channels are grouped into channel-storage banks. Your scanner has 20 channel-storage banks. Each bank contains 50channel sets. So the scanner has 1,000 channels. You can scan the channel-storage banks to see if there is activity on the frequencies stored there.

Note: Search for frequencies to ﬁnd your local frequencies, after you have programmed these frequencies into channels, you can scan the channels.

Service Banks

The scanner is preprogrammed with all the frequencies allocated to the Marine, CB band, FRS/GMRS/MURS, Police (Fire/Emergency), Aircraft and Ham band services. This helps you quickly ﬁnd active frequencies instead of doing a chain search.

Channel-Storage Banks

To make it easier to identify and select the channels you want to listen to, all the channels are divided into 20 banks of 50 channels. Use each channel-storage bank to group frequencies.

For example, the police department might use four frequencies in your town while the ﬁre department uses an additional four. You could program the four police frequencies starting with Channel 0 (the ﬁrst channel in Bank 0), and program the ﬁre department frequencies starting with Channel 50 (the ﬁrst channel in Bank 1).

Scanner Setup

Manual Mode

To enter Manual Mode from any other mode, press MAN/MENU.

Programming Frequencies into Channels

Before the scanner can begin to scan, you must program a frequency into at least one channel.

To locate and store speciﬁc frequencies into channels for later use:

1. From Manual Mode, press ENT/PGM to put the scanner in Programming Mode.

2. Press FUNC + S or T to select a bank.

3. Press S or T to select a channel

4. Use the number keys to enter the frequency, using • for the decimal point.

5. Press ENT/PGM to store the frequency into the channel.

6. To program the next channel in sequence, press

S or ENT/PGM and repeat Steps 4 and 5.

Programming Notes:

• If you entered an invalid frequency in Step 5,

“Invalid Freq.” appears and the scanner beeps error tones. Enter a valid frequency.

• If you entered a frequency in Step 5, which already exists on another channel, the scanner beeps an error tone and displays that channel. Press CL to clear the display, or press ENT/PGM to store the frequency in both channels.

• To erase a frequency from a channel, from Manual Mode press ENT/PGM to enter Programming Mode and then press CL.

Scanner Setup

“Erase Frequency” will appear; press ENT/PGM to erase.

• The scanner automatically rounds the entered number to the nearest valid frequency. For example, if you enter 151.473 (MHz), your scanner accepts it as 151.475.

• After a transmission, the scanner automatically pauses for 2 seconds on this channel before proceeding to the next active transmission. Press •/DELAY to turn the delay function on or off. The scanner stores this setting in the channel.

• To store trunked system frequencies, see “Programming Trunked Frequencies” on p. 46.

If you do not have a list of frequencies in your area, use a chain, ﬁne tune, or service search to ﬁnd a transmission (see “Searching” on p. 21). Also refer to www.radioreference.com.
