. 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.
CONNECTING AN EXTENSION SPEAKER
In a noisy area, an external speaker (not supplied), available at your local RadioShack store, might provide
more comfortable listening. Plug the speaker cable’s 1/8-inch (3.5 mm) mini-plug into your scanner’s
speaker jack on the back. This automatically disconnects the internal speaker.

CONNECTING THE CLONE CABLE
You can transfer the programmed data to and from another PRO-2053 or PRO-93 using the clone cable
(not supplied). We recommend to use RadioShack Cat. No. 42-2420. Connect the cable between each
scanner’s PC/IF jacks. See “Cloning the Programmed Data from Scanner to Scanner” on Page XX. You
can also upload or download the programmed data to or from a PC using an optional PC interface kit
available by special order from 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 determine 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 search function.
You can also search the SEARCH banks, which are preprogrammed frequencies in the scanner’s memory
(see “Searching a Preprogrammed Frequency Range” on Page XX for the frequency list). You can change
the SEARCH frequency ranges in search bank 5.
When you find a frequency, you can store it into a programmable memory location called a channel, which
is grouped with your other channels 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. See “Trunking Operation” on Page XX for
terms related to trunking systems.
A LOOK AT THE KEYPAD
Your scanner’s keys might seem confusing at first, but this information should help you understand each
key’s function.
