The Basics 4

powering your scanner

You can power your scanner from any of three sources:
internal batteries (not supplied)
standard AC power (using an optional AC adapter)
vehicle battery power (using an optional DC adapter)
Before installing batteries, set the switch in the battery compartment to match the type of batteries you will use. Select RECHARGEABLE for all non-alkaline battery types, including lithium, Ni-Cd and Ni-MH.
Remove battery cover and set battery switch.
5 The Basics
Install 2 AA batteries, matching the polarity
symbols (+ -).
Replace the cover.
The Basics 6
Warning: Set ALKALINE/RECHARGEABLE to RECHARGEABLE for use only with nickel cadmium
(Ni-Cd) or nickel metal hydride (Ni-MH) rechargeable batteries. Never attempt to recharge non­rechargeable batteries. Non-rechargeable batteries can get hot or explode if you try to recharge them.
Cautions:
Use only fresh batteries of the required size and recommended type.
Do not mix batteries of different capacities or different chemistries.
Always remove old or weak batteries. Batteries can leak chemicals that destroy electronic circuits.
When flashes and the scanner beeps every 15 seconds, replace both batteries.
Warning: Always dispose of old batteries promptly and properly. Do not bury or burn them.

using rechargeable batteries

You can also use two rechargeable batteries to power your scanner. Before you use Ni-Cd or Ni-MH batteries, you must charge them.
The scanner has a built-in circuit that lets you recharge Ni-Cd or Ni-MH batteries while they are in the scanner. To charge the batteries, set ALKALINE/
7 The Basics
RECHARGEABLE inside the battery compartment to RECHARGEABLE, install the batteries in the scanner,
and connect an external AC or DC adapter to the scanner's DC 6V jack (see “using AC power” on Page 10 or “using vehicle battery power” on Page 11).
Warning: Do not connect either the AC or DC adapter to the scanner if non-rechargeable batteries (such as alkaline batteries) are installed in the scan­ner and ALKALINE/RECHARGEABLE is set to RECHARGEABLE, or if you are unsure of the switch's position. Non-rechargeable batteries will get hot and can even explode if you try to recharge them.
Before you use Ni-Cd or Ni-MH batteries for the first time, charge them for 14 hours to bring them to a full charge.
Discharged batteries take about 14 hours to fully recharge.
Notes:
Ni-Cd batteries last longer and deliver more power if you occasionally let them fully discharge. To do this, simply use the scanner
until it beeps every 15 seconds and flashes.
To prevent damage to Ni-Cd batteries, never charge them in an area where the temperature is above 113°F (40°C) or below 40°F (4°C).
The Basics 8
If you connect an external power source to the
scanner with ALKALINE/RECHARGEABLE set to ALKALINE, CHArg appears but the scanner does NOT charge the batteries. This is because the scanner's microprocessor unit does not recognize the switch position when you incorrectly connect an external power source. Make sure that you use the correct batteries and set ALKALINE/RECHARGEABLE to the correct position when you connect an external power source.
Important: The EPA certified RBRC Battery Recycling Seal on the rechargeable battery indicates RadioShack is voluntarily participating in an industry program to collect and recycle these batteries a the end of their useful life, when taken out of service in the United States or Canada. The RBRC program provides a convenient alternative to placing used rechargeable batteries into the trash or the municipal waste stream, which may be illegal in your area. Please call 1-800-THE-SHACK (1-800-843-7422) for information on rechargeable battery recycling and disposal bans/restrictions in your area. RadioShack's involvement in this program is part of the company's commitment to preserving our environment and conserving our natural resources.
9 The Basics

using AC power

You can power the scanner using a 6V, 300 mA AC adapter and a size B Adaptaplug™ adapter (neither supplied). Both are available at your local RadioShack store.
Cautions:
You must use a Class 2 power source that supplies 6V DC and delivers at least 300 mA. Its center tip must be set to positive and its plug must fit the scanner's DC 6V jack. Using an adapter that does not meet these specifications 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, disconnect the adapter from AC power before you disconnect it from the scanner.
Follow these steps to use the scanner on AC power.
Make sure the power is turned off.
Insert the Adaptaplug into the AC adapter's
cord so it reads TIP +. Then, insert the Adaptaplug into the scanner's DC 6V jack.
Plug the AC adapter into a standard AC outlet.
The Basics 10

using vehicle battery power

You can power the scanner from a vehicle's 12V power source (such as a cigarette-lighter socket) using a 6V, 300 mA DC adapter and a size B Adaptaplug (neither supplied). Both are available at your local RadioShack store.
Cautions:
You must use a power source that supplies 6V DC and delivers at least 300 mA. Its center tip must be set to positive and its plug must fit the scan­ner's DC 6V jack. Using an adapter that does not meet these specifications could damage the scanner or the adapter.
Always connect the DC adapter to the scanner before you connect it to the power source. When you finish, disconnect the adapter from the power source before you disconnect it from the scanner.
Make sure the power is turned off.
If the adapter has a voltage switch, set the switch
to 6V.
Insert the Adaptaplug into the DC adapter's cord
so it reads TIP +. Then, insert the Adaptaplug into the scanner's DC 6V jack.
Plug the other end of the adapter into your
vehicle's cigarette-lighter socket.
11 The Basics
If rechargeable batteries are installed and
ALKALINE/RECHARGEABLE is set to RECHARGEABLE, the adapter powers the scanner
and recharges the installed batteries at the same time.
Note: If the scanner does not operate properly when you use a DC adapter, unplug the adapter from the cigarette-lighter socket and clean the socket to remove ashes and debris.
The Basics 12

setting up your scanner

connecting the antenna

To attach the supplied flexible antenna to the connector on the top of your scanner, align the slots around the antenna's connector with the tabs on the scanner's BNC connector. Then slide the antenna's connector down over the scanner's connector and rotate the antenna connector's outer ring clockwise until it locks into place.

connecting an optional antenna

The scanner's BNC connector makes it easy to connect a variety of optional antennas, including an external mobile antenna or outdoor base station antenna. Your local RadioShack store sells a wide selection of antennas.
13 The Basics
Note: Always use 50-ohm, RG-58, or RG-8, coaxial cable to connect an outdoor antenna. If the antenna is more than 50 feet from the scanner, use RG-8 low­loss dielectric coaxial cable. If your antenna's cable does not have a BNC connector, your local RadioShack store carries a variety of BNC adapters.

connecting an earphone/headphone

For private listening, you can plug a 1/8-inch (3.5 mm) mini-plug earphone or mono headphones (not supplied) into the headphone jack on top of your scanner. This automatically disconnects 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 permanent hearing loss.
Set the volume to the lowest setting before you begin listening. After you begin listening, adjust the volume to a comfortable level.
The Basics 14
Once 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.

traffic safety

Do not use an earphone or headphones with your scanner when operating a motor vehicle in or near traffic. Doing so can create a traffic hazard and could be illegal in some areas.
If you use an earphone or headphones with your scanner, be very careful. Do not listen to a continuous broadcast. Even though some earphones/headphones let you hear some outside sounds when listening at normal volume levels, they still can present a traffic hazard.

connecting an extension speaker

In a noisy area, an optional extension speaker, posi­tioned in the right place, might provide more com­fortable listening. Plug the speaker cable's (3.5-mm) mini-plug into your scanner's headphone jack. Your local RadioShack store carries a selection of suitable speakers.

/8-inch
Warning: If you connect an external speaker to the scanner's headphone jack, never connect the audio output line to a power supply and ground. This might damage the scanner.
15 The Basics

attaching the belt clip

To make your scanner easier to carry when you are on the go, use the supplied belt clip. Use a Phillips screwdriver and the supplied screws to attach the clip to the scanner.
The Basics 16

about 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. Simply determine the type of communications you want to receive, and then set the scanner to scan those communications.
A frequency, expressed in kHz or MHz, is the tuning location of a station. To find active frequencies, you use the search function or refer to a frequency refer­ence.
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 the type of services that use those frequencies. 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. The scanner has 10 channel­storage banks and each bank has 20 channels. You can scan the channel-storage banks to see if there is activity on the frequencies stored there.
