About Your Scanner
• 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.
Traffic Safety
Do not wear an earphone or headphones
while you drive a vehicle or ride a bicycle.
This can create a traffic hazard and can be il-
legal in some areas. Even though some ear-
phones and headphones let you hear some
outside sounds when you listen at normal
levels, they still can present a traffic hazard.
CONNECTING AN
EXTENSION SPEAKER
In a noisy area, an extension speaker (not
supplied), available at your local RadioShack
store, might provide more comfortable listen-
ing. Plug the speaker cable's
1
/
8
-inch (3.5
mm) mini-plug into your scanner's
EXT SPKR
jack.
TRANSFERRING DATA TO
AND FROM ANOTHER
SCANNER OR A PC
You can transfer the programmed data to
and from another PRO-2053 or PRO-93 us-
ing a connecting 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 Programmed Data”
on Page 29. You can also upload or down-
load the programmed data to or from a PC
using an optional PC interface kit available
through your local RadioShack store.

About Your Scanner
Once you understand a few simple terms
used in this manual and familiarize yourself
with your scanner's features, you can put the
scanner to work for you. You simply deter-
mine the type of communications you want to
receive, then set the scanner to scan them.
A frequency is the receiving signal location
(expressed in kHz or MHz). To find active
frequencies, you can use the tune function.
You can also use the SEARCH banks, which
are preprogrammed frequencies in the scan-
ner's memory (see “Searching a Prepro-
grammed Frequency Range” on Page 18 for
the frequency list). You can even change the
frequency range on one of the SEARCH
banks (SR5) to limit the search.
When you find a frequency, you can store it
into a programmable memory location called
a channel, which is grouped with other chan-
nels in a channel-storage bank. You can
then scan the channel-storage banks to see
if there is activity on the frequencies stored
there. Each time the scanner finds an active
frequency, it stays on that channel until the
transmission ends.
A LOOK AT THE KEYPAD
