supplying power to your scanner

You can power your scanner with batteries or an AC adapter.
Warning: Only set the switch inside the battery compartment to NiMH for use with

nickel metal hydride (NiMH) rechargeable batteries. Never use non-rechargeable batteries when
the switch is set to NiMH.

Set the switch inside the battery compartment to the appropriate setting.

• ALKALINE when using alkaline batteries (not included).
Caution: You must use a Class 2 power source that supplies 6V DC and delivers at least 800mA.

Its center tip must be set to positive and its plug must fit the scanner’s DC 6V 800mA jack. Using
an adapter that does not meet these specifications could damage the scanner or the adapter.

• NiMH when using rechargeable (NiMH) AA batteries (not included). The scanner stops
charging automatically after at most14 hours when the DC jack is connected to power.

battery cautions

• Use only fresh batteries of the required size and recommended type.

- 2 -

• Always remove old or weak batteries. Batteries can leak chemicals that damage electronic

circuits.

• Do not mix old and new batteries, different types of batteries (standard, alkaline, or

rechargeable), or rechargeable batteries of different capacities.

• When the battery icon flashes and the scanner beeps every 15 seconds, replace all

three batteries.

• Always dispose of old batteries promptly and properly. Do not bury or burn them.
Warning: Do not connect a charging adapter to the scanner if non-rechargeable batteries (such

as alkaline batteries) are installed in the scanner and the switch is set to NiMH, 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.

• 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.

connecting the antenna

Attach the supplied antenna to the scanner by screwing it tightly onto the anchor post at the top
of the radio. When using an external antenna, always use 50-ohm, RG-58, or RG-8, coaxial
cable to connect to it. 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 SMA connector, your local
RadioShack store carries a variety of SMA adapters.

connecting an earphone/headphone

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 “mono”
and not stereo.

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.

• 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.
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.

attaching the belt clip

To attach the belt clip:

1. Rotate the belt clip so that the finger indentation is towards the top of the radio.

2. Align the center of the clip with the anchor post.

3. Place the clip on the post and slide the clip upwards until it clicks into place.
To remove the belt clip:

1. Rotate the clip so that the finger indentation is towards the bottom of the radio.

2. Slide the clip up until it comes free of the anchor post.

transferring data to or from another scanner or pc

You can transfer the programmed data to and from another 20-137 scanner using a connecting

- 3 -

cable which has 1/8-inch phone plugs on both ends (not supplied). Connect
the cable between each scanner’s PC/IF jacks. See “cloning your scanner”. You can
also upload or download the programmed data to or from a PC using an optional PC interface
cable and software available through your local RadioShack store. See
“wired programming.”

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, then set the
scanner to scan those communications.

The scanner scans conventional frequencies and racing.
A frequency, expressed in kHz or MHz, is the tuning location of a station. To find active

frequencies, you use the search function.
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 channel-storage banks. Each bank contains 100-channel 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: You search frequencies when you want to find your local frequencies and scan channels
after you programmed your found frequencies.

understanding banks

service banks

The scanner is preprogrammed with all the frequencies allocated to the Car Band, Marine,
Fire/Police, Aircraft, and Ham Band services. This helps you quickly find active
frequencies instead of doing a chain search (see “service bank 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 10 banks of 100 channels. Use each channel-storage bank to group frequencies,
such as those for the police department, fire department, ambulance services, or aircraft. 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 100 (the first channel in bank 1).

turning on the scanner

Make sure the scanner’s antenna is connected, then press and hold / KEYLOCK. The
scanner turns on.

setting the volume

1. Push the SEL/VOL/SQL knob.

2. Rotate the knob to select the volume level you want to set from 0 to 15.

setting the squelch

1. Press Func, then push the SEL/VOL/SQL knob.

2. Rotate the knob to select the squelch level you want to set from 0 to 15.

Using the Scanner at the Racetrack

You can hear drivers communicating with their pit crews, officials communicating with drivers
and crews, and track workers communicating with everybody.
Each user at the racetrack transmits and receives on one or more frequencies.
The scanner organizes racetrack frequencies by the name of the race you are scanning and by
car number. For example, you might hear drivers and their pit crews on the car number
frequencies and officials and the news media on the race frequencies. When you are scanning,
the scanner stops very briefly on each channel to see if there is activity. If there isn’t, the scanner
quickly moves to the next channel. If there is, then the scanner pauses on the transmission until
it is over. You can activate one racing system and as many conventional systems as you want at
the same time. Within a racing system, each driver can have multiple frequencies stored.

before you get to the track

Each driver’s team has several different frequencies they can use during a race. These
frequencies can change depending on local interference sources or other frequency issues. Your
scanner is preprogrammed with all of the drivers and their possible frequencies that were known
when it was manufactured.
Before you leave for the track, check the Internet to see if there are any frequency updates
available for your race. You can save time at the track by setting up as much as possible before
you leave.

when you get to the track

When you arrive at the race, get a list of the actual frequencies in use that race day. These are
normally available for sale on the way into the facility. This list will show the actual frequency
being used by each driver that day, as well as some other useful frequency information.
Then, follow the steps in the sections below to adjust the scanner settings.
